Sprint Corporation, commonly referred to as Sprint, is an American telecommunications holding company that provides wireless services and is an internet service provider. It is the fourth largest mobile network operator in the United States, and serves 54 million customers as of October 2017.  The company also offers wireless voice, messaging, and broadband services through its various subsidiaries under the Boost Mobile, Virgin Mobile, and Assurance Wireless brands, and wholesale access to its wireless networks to mobile virtual network operators. The company is headquartered in Overland Park, Kansas. In July 2013, a majority of the company was purchased by Japanese telecommunications company SoftBank Group Corp.,  although the remaining shares of the company continue to trade on the New York Stock Exchange.. Sprint is a CDMA carrier which uses CDMA, EvDO and 4G LTE networks.
Sprint traces its origins to the Brown Telephone Company, which was founded in 1899 to deploy telephone service to the rural area around Abilene, Kansas. In 2006, Sprint exited the local landline telephone business, spinning those assets off into a newly created company named Embarq, which later became a part of CenturyLink. The company continues to be one of the largest long distance providers in the United States.
Prior to 2005, the company was also known as the Sprint Corporation, but took the name Sprint Nextel Corporation when it merged with Nextel Communications that year. In 2013, following the shutdown of the Nextel network and concurrent with the acquisition by SoftBank, the company returned to using simply Sprint Corporation. In July 2013, as part of the SoftBank transactions, Sprint acquired the remaining shares of wireless broadband carrier Clearwire Corporation which it did not already own.
Foundation and early years
Sprint Corporation traces its origins to the Brown Telephone Company, which was founded in 1899 by Cleyson Brown and Jacob Brown to deploy telephone service to the rural area around Abilene, KS.  The Browns installed their first long-distance circuit in 1900 and chartered their own company in October 1902.
In March 1903, they joined with 14 other Kansas independents to incorporate the Union Telephone and Telegraph Company, which would provide long-distance service to Kansas City.
In September 1911, C.L. Brown consolidated the Brown Telephone Company with three other independents to form the second largest telephone company in Kansas, the United Telephone Company, which controlled seven major telephone exchanges.
C.L. Brown formed United Telephone and Electric (UT&E) in 1925 in order to purchase stock in subsidiary companies across widely scattered geographical areas. Brown's UT&E eventually controlled more than 68 other companies, more than two-thirds of which were telephone companies.
Bankruptcy and reorganization
The Great Depression caused more than three million telephone subscribers to give up their phone service between 1931 and 1933. Consequently, UT&E suffered severe financial strain and had to seek protection to reorganize under bankruptcy laws. All but six of UT&E's 85 companies survived, with some showing profits again in 1936. During the reorganization, a number of companies were merged and later phased out. The reorganization plan received final approval in late 1937.
UT&E was dissolved, and its assets were placed in a newly formed company, United Utilities, Incorporated, in 1938.
United Telecommunications (United Telecom)
When Paul H. Henson became president of United Utilities in 1964, he almost immediately reorganized the company in accordance with C.L. Brown’s belief that centralizing some of the company’s functions would result in greater efficiency, cost reductions, and growth. In 1972, United Utilities changed its name to United Telecommunications, commonly referred to as "United Telecom". In 1980, United Telecom launched a national X.25 data service, Uninet. To enter the long-distance voice market, United Telecom acquired ISACOMM in 1981 and US Telephone in 1984. In 1983, United Telecom began offering cellular telephone services in their territories under the brand name "Telespectrum".
Southern Pacific Communications and introduction of Sprint
Southern Pacific Communications Company (SPC), a unit of the Southern Pacific Transportation Company, began providing long-distance telephone service after the Execunet II decision late in 1978. SPC was headquartered on Adrian Court in Burlingame, California, where Sprint still maintains its Sprint Applied Research & Advanced Technology Labs.
Southern Pacific maintained an extensive microwave communications system along its rights-of-way that the railroad used for internal communications. After the Execunet II decision, Southern Pacific expanded its internal communications network by laying fiber optic cables along the same rights-of-way. In 1972, Southern Pacific Communications began selling surplus system capacity to corporations for use as private lines, circumventing AT&T's then-monopoly on public telephony. Prior attempts at offering long distance voice services had not been approved by the U.S. Federal Communications Commission (FCC), although a fax service (called SpeedFAX) was permitted.
Southern Pacific Communications was only permitted to provide private line services, not switched services. After MCI Communications won the court battle giving MCI the right to begin offering Execunet services, Southern Pacific Communications took the Federal Communications Commission to court to get the right to offer switched services, and succeeded (the "Execunet II" decision). Southern Pacific Communications decided they needed a new name to differentiate the switched voice service from SpeedFAX, and ran an internal contest to select a name. The winning entry was "SPRINT", an acronym for Southern Pacific Railroad Internal Network Telecommunications. 
The Sprint service was first marketed in six metropolitan areas: New York City, Boston, Philadelphia, Los Angeles, San Diego, and Anaheim. The first three switches were purchased from Danray, in Plano, Texas, and were located in Los Angeles, New York and Chicago. A customer was required to have a private line connection to one of these switches in order to use the service and paid an access fee per private line. Access was also available by dialing an access number to connect to the SPRINT switch. Customers were then billed at 2.6 cents per tenth of a minute increment.
Consolidation and renaming to Sprint Corporation
In 1982, SPC and GTE entered into merger negotiations, and in 1983, GTE purchased SPC and renamed the company GTE Sprint Communications Corporation (or "GTE Sprint").
GTE had acquired a national X.25 provider Telenet in 1979. In 1986, GTE Sprint and Telenet merged with the United Telecom properties US Telecom, Uninet, and ISACOMM, forming US Sprint. This was a joint venture co-owned by GTE and United Telecom. In 1988, United Telecom sold Telespectrum to Centel to fund the purchase of an additional 30% of US Sprint. This purchase gave United Telecom operational control of US Sprint.
In 1989, United Telecom purchased a controlling interest, and in 1991, it completed its acquisition of US Sprint. On February 26, 1992, United Telecommunications adopted the nationally recognized identity of its long distance unit US Sprint, changing its name to Sprint Corporation, due in large part to the increased brand recognition as a result of the successful Candice Bergen "Dime Lady" advertisement campaign.
Expansion into Canada
Sprint Corporation entered the Canadian market in the early 1990s as a reseller of bulk long-distance telephone lines that it bought from domestic companies. Under Canadian foreign ownership regulations, Sprint could not open its own network. In 1993, Sprint entered into a strategic alliance with Call-Net Enterprises, a Canadian long-distance service, and bought 25 percent of the company. Call-Net’s long-distance service was renamed “Sprint Canada”, and expanded to include landline and internet services. In 2005, Call-Net and Sprint Canada’s 600,000 customers were acquired by Rogers Communications. 
Return to wireless
In 1993, Sprint acquired Centel, allowing Sprint to provide local service in a total of 18 states, putting them back in the wireless market. In 1994, Sprint spun off their existing cellular operations as "360 Communications" for regulatory reasons, in order to start a new service in the PCS band. In 1998, 360 Communications was acquired by Alltel, which was in turn acquired by Verizon in 2009.
In late 1994 and early 1995, Sprint acquired near nationwide 1900Mhz PCS spectrum, via Sprint Spectrum–APC (a joint venture between Sprint and several cable companies). Later in 1995, the company began to offer wireless service under the Sprint Spectrum brand in the Baltimore-Washington metropolitan area. This was the first commercial PCS network in the United States. Although the current Sprint PCS service is CDMA, the original Washington-area network used GSM. Eventually, Sprint launched its new nationwide CDMA network, then in 1999 sold the decommissioned GSM infrastructure to Omnipoint which re-launched in May 2000. Omnipoint was later acquired by VoiceStream Wireless, which eventually became part of T-Mobile USA.
Partnerships and more consolidation
In September 1996, Sprint announced a deal with RadioShack, and in 1997, Sprint stores opened at RadioShack to offer communications services and products across the United States. Since then, over 20 million Sprint cell phones have been sold via the RadioShack outlets. RadioShack was one of the first retailers to offer Sprint services and an all-digital nationwide network for its customers.
On October 5, 1999, Sprint and MCI WorldCom announced a $129 billion merger agreement between the two companies. The deal would have been the largest corporate merger in history at the time. However, due to pressure from the United States Department of Justice and the European Union on concerns of it creating a monopoly, the deal did not go through.
In 1999, Sprint began recombining its local telecom, long distance, wireline, and wireless business units into a new company, in an initiative known internally as "One Sprint". In April 2004, the separately traded wireless tracking stock PCS was absorbed into the New York Stock Exchange FON ticker symbol, Sprint's former ticker symbol (FON stood for "Fiber Optic Network", but was also a homophone of the word "phone"). This was challenged in many lawsuits by Sprint PCS shareholders who felt their stock was devalued because it was trading at the ratio of 1 share of PCS stock for 1/2 share of FON stock. The PCS shareholders claimed a loss of 1.3 billion to 3.4 billion dollars.
Merger of Sprint Corporation and Nextel Communications
On December 15, 2004, Sprint Corporation and Nextel Communications announced they would merge to form Sprint Nextel Corporation. While billed as a merger of equals, the merger was transacted as purchase of Nextel Communications by Sprint Corporation for tax reasons; Sprint purchased 50.1 percent of Nextel. At the time of the merger announcement, Sprint and Nextel were the third and fifth leading providers in the U.S. mobile phone industry, respectively.
Sprint shareholders approved the merger on July 13, 2005. The merger deal was approved by the U.S. Federal Communications Commission (FCC) and U.S. Department of Justice on August 3, 2005. The FCC approved the merger on the condition that Sprint Nextel was to provide wireless service via the 2.5 GHz band within four years. Sprint Nextel was formed on August 12, 2005, when the deal was completed.
Sprint and Nextel faced opposition to the merger, mostly from regional affiliates that provided wireless services on behalf of the companies. These regional affiliates felt that the new company would be violating non-compete agreements that the former companies had made with the affiliates.
On September 1, 2005, Sprint Nextel combined plan offerings of its Sprint and Nextel brands to bring uniformity across the company's offerings.
Nextel has licensed its identity to NII Holdings, Inc., of which Sprint Nextel owned 18%. NII has used the Nextel brand to set up networks in many Latin American countries. Following Sprint's purchase of Nextel, Nextel sold all of its investment in NII Holdings.
The integration process was difficult due to disparate network technologies. Sprint tried to address this with the advent of PowerSource phones. These phones routed voice call and data services over Sprint's PCS spectrum, while maintaining DirectConnect services over 800 MHz spectrum. However, this was not sufficient in coverage, due to the inability to roam on non-PCS spectrum. Soon after the merger, top Nextel Executives began leaving the company immediately after the merger closed. Tim Donahue, Nextel CEO, stayed on as executive chairman, but ceded decision-making authority to Gary D. Forsee. Tom Kelly, COO of Nextel, took an interim staff position as Chief Strategy Officer. Two years after the merger, only a few key Nextel executives remained, with many former Nextel middle- and upper-level managers having left, citing reasons including unbridgeable cultural difference between the two companies.
Sprint's acquisition of Nextel was a disaster from a fiscal standpoint – in 2008, the company wrote down $29.7 billion of the $36 billion sum it had paid for Nextel in 2005, wiping out 80 percent of the value of Nextel at the time it had been acquired.  The write down reflected the depreciation in Nextel's goodwill since the date of acquisition. 
Affiliate acquisitions and settlements
Prior to their merger, Sprint and Nextel were dependent on a network of affiliated companies. Following the announcement of the merger agreement, some of these affiliates came forward with a strong opposition to the Sprint-Nextel merger on the grounds that the merged company might violate existing agreements or significantly undercut earnings to these affiliates. In order for Sprint Nextel to allay some of this opposition, they initiated discussions of either acquiring some of these affiliates or renegotiating existing agreements. In several cases, the newly formed company was forced to acquire affiliated companies in exchange for their dropping their opposition to the merger. Foresee said that the company would likely have to acquire all of its remaining affiliates.
In 2005, Sprint Nextel acquired three of its ten wireless affiliates: US Unwired, acquired in August; Gulf Coast Wireless, acquired in October; and IWO Holdings, acquired in October. Alamosa PCS, which Sprint Nextel acquired on February 2, 2006, was the largest of its affiliate carriers. Other acquired affiliates include Ubiquitel, iPCS, Enterprise, and Northern. Of Sprint's original ten affiliates, only two, Shentel and Swiftel, now remain.
Below are companies which Sprint Corporation has agreed to acquire or has already acquired:
- August 12, 2005: Sprint acquires the Sprint PCS affiliate US Unwired for $1.3B, thus adding 500,000 additional direct customers to Sprint Nextel. 
- August 30, 2005: Sprint Nextel announces its intention to acquire IWO Holdings, Inc., a mainly New England -based network affiliate for the Sprint PCS business. The acquisition closed on October 20, 2005.
- Sprint Nextel acquires Gulf Coast Wireless, adding 95,000 customers, mainly in Louisiana and Mississippi, to Sprint Nextel's CDMA network. The acquisition closed on October 3, 2005.
- November 21, 2005: Sprint Nextel announces a $4.3-billion acquisition agreement for Texas-based Sprint PCS affiliate Alamosa Holdings, potentially adding 1.48 million customers to Sprint Nextel. 
- December 16, 2005: Sprint Nextel announces a $98 million agreement to acquire Enterprise Communications of Columbus, Georgia, thus adding over 52,000 customers to the company's PCS Wireless division. 
- December 16, 2005: Sprint Nextel announces acquisition of non-affiliate Velocita Wireless. The transaction enhances the iDEN network's 900 MHz spectrum position.  On July 2, 2007, Velocita Wireless, which became an indirect subsidiary of Sprint Nextel, was acquired by United Wireless Holdings, Inc. 
- December 21, 2005: Sprint Nextel Corporation and Nextel Partners, Inc. reach an agreement for a $6.5 billion deal whereby the Sprint Nextel Corporation acquires the largest of Nextel's affiliates to end Nextel Partners' opposition to any changes by Sprint in relation to the Sprint-Nextel merger. Once completed, the Nextel Partners deal adds more than 2 million customers directly to the Sprint Nextel company. 
- April 20, 2006: Sprint Nextel Corporation and Ubiquitel PCS Corporation reach an agreement whereby the Sprint Nextel Corporation acquires Ubiquitelpcs, an exclusive Sprint PCS provider. 
- March 17, 2007: Sprint Nextel Corporation completes integration of Nextel Partners customers into the Sprint Nextel system. Nextel Partners' Las Vegas headquarters shuts down service, and all Nextel Partners customers are now handled through the new "Ensemble" billing system. All Nextel Partners customers are now Sprint Nextel customers and are entitled to the same promotions as all other Sprint Nextel iDEN customers.
- August 2, 2007: Sprint Nextel Corporation completes the acquisition of Northern PCS for $312.5 million including debt. 
- July 28, 2009: Sprint Nextel announces a $483 million acquisition agreement for Virgin Mobile USA, adding 5 million pre-paid customers to Sprint Nextel, although these subscribers were counted in Sprint's total subscriber count, as Virgin Mobile USA was an MVNO on Sprint's CDMA network. 
- October 19, 2009: Sprint Nextel agrees to acquire iPCS, one of its last remaining affiliates. 
Consolidation to Overland Park
After the Sprint-Nextel merger, the company maintained an executive headquarters in Reston, Virginia and operational headquarters in Overland Park, Kansas. Sprint CEO Dan Hesse recognized that having two headquarters was not helping the merger effort, sent the wrong message to employees and contributed to the post-merger cultural clash. To resolve the problem, Hesse decided to consolidate all headquarters operations in the Sprint World Headquarters Campus located in Overland Park, Kansas, a suburb in the Kansas City metropolitan area.
Acquisition by SoftBank Corporation
On October 14, 2012, the Japanese telecommunications company SoftBank announced it intended to purchase 70% of Sprint Nextel Corporation for $20.1 billion. SoftBank states that Sprint will remain a separate entity, will remain a CDMA carrier and will continue executing Sprint's plan to become an all-LTE carrier by 2017. On April 15, 2013, Dish Network announced a higher bid for Sprint Nextel than the offer placed by SoftBank, with an $25.5 billion offer. On June 18, 2013, DISH retracted its bid and decided that it would instead focus on its intent to purchase Clearwire, however on June 26, 2013, DISH also retracted its bid for Clearwire, leaving the road clear for SoftBank to acquire the company. The United States Federal Communications Commission approved SoftBank's acquisition of a stake in Sprint. The FCC's acting chairwoman Mignon Clyburn and commissioner Ajit Pai both gave statements vociferously supporting the acquisition, saying the deal "serve[s] the public interest". The acquisition was completed on July 10, 2013.
On August 6, 2013, SoftBank purchased approximately 2% more shares of Sprint Corporation, increasing its ownership stake in the company to 80%. 
On November 7, 2012, Sprint Nextel announced the acquisition of 20 MHz of spectrum and 585,000 customers from US Cellular in Chicago, St. Louis, central Illinois and three other Midwest markets. The deal was expected to close in mid-2013. 
Prior to July 9, 2013, Sprint Nextel only owned a 50.8% equity interest in Clearwire Corporation; On December 17, 2012, Sprint Nextel agreed to pay US$2.97 per share, US$2.2 billion in total, to purchase the portion of Clearwire shares that Sprint Nextel did not already own. On June 20, 2013, Sprint Nextel increased its offer to $5 per share, the transaction was approved by regulators on July 5, 2013, and closed on July 9, 2013, and Sprint Nextel became the complete owner of Clearwire and its assets.
On March 31, 2015, the U.S. bankruptcy court approved a $160 million takeover of electronics store chain RadioShack by Standard General; as part of the deal, the company entered into a partnership with Sprint to serve as co-tenants in 1,435 of its locations, beginning on April 10, 2015. Roughly a third of the retail space in each location is dedicated to Sprint products and services, and the stores will ultimately adopt Sprint as their primary brand in place of RadioShack. Sprint stated that this deal would increase the company's retail footprint by more than double. 
On February 17, 2017, it was reported by Reuters that Softbank was considering selling its majority share in the company to Deutsche Telekom, which would effectively merge the carrier with T-Mobile US.  However, after months of speculation and rumors about a potential deal being reached, both Sprint and T-Mobile announced on November 4th, 2017, that while they have had discussions about a merger, they have both decided to end talks about any mergers with each other due to not being able to agree on the terms of the combined deal  (Softbank's board of directors reportedly held a vote on October 27th where they decided not to give up control of Sprint  ).

Sprint Web Services
Sprint offers its enterprise customers managed web based services through its Sprint Web Services  program. It allows enterprise customers to create managed web-based applications
IoT & Connected Services
Telecommunications Relay Services
Sprint wireline is also responsible for traditional telecommunications relay service (TRS), speech to speech relay service (STS), and captioned telephone service (CTS). Sprint is in the process of upgrading these services from a TDM network to an IP based network 
Sprint branded services
Sprint Corporation offers post paid wireless voice and data services primarily under the Sprint brand.
Sprint Prepaid Group
The Sprint Prepaid Group is a division of the company formed in May 2010 that is responsible for the operations of Sprint's pre-pay subsidiaries. SPG's branded products and services are sold via web and available at retailers nationwide, including Best Buy, Walmart, Target and other independent dealers.
Boost Worldwide, Inc. is a wholly owned subsidiary of Sprint that provides nationwide, prepaid wireless voice, messaging and broadband data products and services to customers in the continental United States under the Boost Mobile brand. The services are provided as an MVNO hosted on the Sprint-owned CDMA, EVDO, WiMAX, LTE, and now the Sprint LTE Plus Network.
Virgin Mobile and Assurance Wireless
Virgin Mobile USA, L.P. is a wholly owned subsidiary of Sprint Corporation which provides nationwide, prepaid wireless voice, messaging, and broadband data products and services to customers in the continental United States under the Virgin Mobile, payLo, and "Assurance Wireless Brought to You by Virgin Mobile" brands. It operates as an MVNO that provides services to its customers via the Sprint-owned CDMA, EVDO, WiMAX, and LTE networks.  Virgin Mobile USA targets younger consumers and serves approximately 6 million users.
Virgin Mobile USA, L.P. also offers lifeline telephone service subsidized by the U.S. Federal Communications Commission's Universal Service Fund under the "Assurance Wireless Brought to You by Virgin Mobile" brand. The program offers a free wireless phone and 250 free local and domestic long distance voice minutes per month to eligible low-income customers in 31 states. End users do not receive a bill, nor are they required to sign a contract, and do not pay activation fees, recurring fees, or surcharges. 
Sprint Smart Velocity
Sprint Velocity is Sprint Corporation's Connected Vehicle Platform.
Wireless wholesale operations and affiliates
Sprint Corporation provides services using both its own spectrum and network equipment through affiliate agreements. Smaller affiliated companies operate their own network assets and retail operations but offer services to customers in their geographic region under the Sprint brand.
In the early stages of network build-out, the company relied significantly on network partners known as affiliates to rapidly expand its coverage. These affiliates would lease Sprint's PCS spectrum licenses in a specific geographic area, typically rural areas and smaller cities, and provide wireless service using the Sprint brand. Sprint provided back-end support such as billing and telephone-based customer service, while the affiliates built and maintained the network, sold equipment to customers, and staffed the retail stores in their specific regions. Its customers could "roam" across Sprint-operated and affiliate-operated portions of the network without being aware of the distinction, and vice versa. Outwardly, efforts were made to make it appear as if the network was operated by a single entity under the Sprint name, though complex revenue-sharing agreements were in place which were very similar in nature to cross-carrier roaming tariffs. In later years, the relationship between Sprint and its affiliates grew contentious, particularly after Sprint's acquisition of Nextel.
Sprint Rural Alliance
Sprint Rural Alliance (SRA) members (aka Sprint Partners) are those carriers who use their own equipment and also sell their own service under their own name while using Sprint spectrum. Sprint is given access to the SRA network in return for allowing use of Sprint spectrum. This allows Sprint to keep the spectrum license for the geographic area being served by the SRA member.
SRA Members: Alaska DigiTel in Alaska.
Former SRA Members: Alltel Wireless in Montana. This portion of the network was obtained by AT&T during the merger of Alltel and Verizon Wireless. Pioneer Cellular in Kansas and Oklahoma ended their agreement with Sprint on March 1, 2012. They have since transitioned to an agreement with Verizon Wireless through the LTE in Rural America program. nTelos that operated in West Virginia and western Virginia was bought out and merged with Shentel which is a Sprint Affiliate.
Mobile virtual network operators (MVNOs)
Sprint Corporation provides wholesales capacity on its CDMA2000, EVDO, and LTE wireless networks to mobile virtual network operators (MVNOs), which allows other wireless providers to utilize its networks to offer its services. Sprint's prepaid brands also operate using Sprint's networks, however they are not MVNOs, but rather wholly owned prepaid subsidiaries of the company.
Bring Your Own Sprint Device
Sprint Corporation allows certain Sprint MVNOs to accept and activate old Sprint-branded phones through its "Bring Your Own Sprint Device" program which was established for Sprint's initiative to further reduce the number of cell phones that are thrown away each year. The program is also beneficial to MVNOs customers who do not want to pay subsidized prices. 
Custom Branded Device Program
Sprint Corporation offers its MVNOs a program called the "Custom Branded Device Program", which gives MVNOs access to completely unbranded Android smartphones with no references to Sprint; the MVNO can then customize with its own branded apps and services through Sprint's Mobile ID and Mobile Zone products. Though these phones are free of Sprint branding, they continue to be certified to run on Sprint networks. 
Data roaming agreements
On May 9, 2006, Sprint Nextel and Alltel agreed on a new Nationwide Roaming partnership.   The new roaming agreement is for voice and 1x and EV-DO data roaming coverage. This is different from the voice-only roaming agreement between Alltel and Verizon Wireless in that it is reciprocal, giving Alltel customers access to the Sprint 1x and EV-DO network, and Sprint customers access to Alltel's denser, rural 1x and EV-DO voice and data coverage. This agreement represents the first of its kind between U.S. wireless carriers. Although Alltel merged with Verizon Wireless in 2008, one of the conditions of the merger was that Verizon would honor all preexisting agreements between Alltel and other companies. The roaming reciprocity agreement between Alltel and Sprint is set to expire in 2016.
Sprint and Verizon Wireless have a reciprocal data roaming agreement  that allows for the use of Sprint Power Vision content like TV, movie downloads, and stream radio in Verizon 1x coverage areas.
Sprint and U.S. Cellular also have a 1xRTT, EVDO and LTE data and voice roaming agreement. Sprint has a LTE roaming agreement with AT&T, which is typically limited to 3G speeds. Cases of where Sprint phones are roaming on Verizon for voice and AT&T for data have been observed in 2017.
The following is a list of known 3G and LTE frequencies which Sprint employs in the United States:
|Frequency Band||Band Number||Protocol||Generation||Status||Notes|
|800 MHz ESMR||10||1xAdvanced||3G||Active||For voice and low-speed data (<150kbit/s). |
|26||LTE||4G||LTE band for "range" and better indoor coverage.|
|1900 MHz PCS||2||1xRTT / 1xAdvanced / EVDO / eHRPD||3G||In the process of refarming to LTE.|
|25||LTE / LTE Advanced||4G||"Primary" LTE band. |
|2.5 GHz BRS/EBS||41||TD-LTE / LTE Advanced||4G||Sprint 8T8R Deployment Underway.  3x20 Carrier Aggregation deployed.  Marketed as "". |
Sprint operates a nationwide CDMA network in the 1900 MHz PCS band. In 2006, Sprint's EV-DO "Power Vision" network reached more than 190 million people. Sprint then continued to upgrade their 3G EV-DO network until it reached 260 million people in 2007. Today, Sprint covers over 300 million POPs with EV-DO services. Sprint has recently added eHRPD to its network (EV-DO routed through an LTE core network) in order to facilitate smooth handoffs between LTE and EV-DO.
On July 28, 2011, Sprint announced that it had decided to end its roll out of the 4G network using WiMAX technology, in favor of more internationally accepted LTE technology. Sprint had also announced that it entered into a 15-year agreement that included spectrum hosting, network services, 4G wholesale and 3G roaming, with LightSquared, although that deal was later dissolved due to regulatory issues which LightSquared was unable to resolve with the FCC.
Sprint announced initial LTE deployment plans at the Sprint Strategy Update conference on October 7, 2011. Network Vision-partner Samsung began LTE deployments on October 27, 2011, in Chicago, Illinois.  Sprint projected that the LTE network would cover 123 million people in 2012 and over 250 million people by the end of 2013.
On January 5, 2012, Sprint announced via Twitter its first 4G LTE markets, that included Atlanta, Dallas, Houston, and San Antonio; on June 27, 2012, Sprint stated that it will launch its new 4G LTE network in the first five markets the following month and on July 15, 2012, Sprint commenced operating the LTE network. In addition to the five announced markets, it was launched in 10 other markets, with more markets to be covered by the end of the year.
Sprint initially deployed LTE in the 1900 MHz G block and over time has added LTE to its 1900 MHz A-F blocks. Sprint has also deployed LTE in the 800 MHz ESMR band and the 2500 MHz band it acquired from Clearwire under the name LTE Plus.
Today, Sprint covers more than 300 million POPs with LTE services.
LTE Plus (previously Sprint Spark)
On October 30, 2013, Sprint announced that it would begin offering devices that are capable of accessing its 2.5 GHz LTE network to post-paid subscribers in the following month. This service, previously called "Sprint Spark", was first announced with limited availability. Sprint more recently rebranded this service as "LTE Plus", demonstrating peak speeds of more than 250 Mbit/s. Sprint has also announced three-channel carrier aggregation and demonstrated a 295 Mbit/s download speed on their HTC 10 smartphone. Today, Sprint Corporation's LTE Plus service is available in more than 150 markets. Most users with LTE Plus enabled phones are still unable to use LTE data while on a voice call. Calling Plus has been introduced to select Android phones, which allows for voice to use LTE but is more limited than VoLTE, as HD Voice is disabled, and Wi-Fi/Wi-Fi calling must be enabled, as well as the phones having harder hand-offs from Wi-Fi to LTE, as opposed from LTE to Wi-Fi. . Sprint has made no announcements to a time frame as to when VoLTE will be launched. 
Wireless products and services
Sprint has a variety of wireless and mobile broadband products selection from a full range of manufactures, that are preloaded with the largest mobile operating systems including Google's Android, Apple's iOS, and Microsoft's Windows Phone. Sprint partner device manufactures include Apple, BlackBerry, HTC, Kyocera, LG, Motorola, Samsung, Sharp, Sonim, and ZTE.
Broadband for the home via Sprint Mobile
In order to offer broadband directly to the home, Sprint launched a co-branded Broadband  Wireless Access Point device along with Linksys, a unit of Cisco Systems. This unit allows Sprint customers to set up a special in a home or office computer network, connecting multiple computers or laptops wirelessly to Sprint's PowerVision network. This broadband service to the Internet will allow some customers to have broadband without paying for telephone service. The PowerVision router may allow one to bypass the local telephone and cable broadband service providers. Such Broadband offerings to the home or office without cable or DSL means the router could be used to provide cheaper VoIP services through Sprint's High Speed network.
Sprint Music Plus
On October 31, 2005, the Sprint Music Store was launched. Initial record-label participation included EMI Music, Sony BMG Music Entertainment, Warner Music Group, and Universal Music Group. On November 1, 2006, after one year of service, the Sprint music store had sold more than 8 million songs, partly thanks to the five free songs it offered customers at launch.  On April 1, 2007, the Sprint Music Store started offering music downloads at the price of 99 cents per track to customers who agreed to subscribe to a Vision pack of $15 or higher. Sprint Music Store is available for all Android 3G and 4G phones, and for the BlackBerry Style 9670 phones, and was launched as the Sprint Music Plus service in 2011, powered by RealNetworks. It offers full track music files from various labels (albums and single tracks), ringback tones, and ringtones. An icon on BlackBerry phones for Sprint Music Store directs users to a page describing that Sprint will release a version of Sprint Music Store soon. In 2011, the Sprint Music Store became available for the BlackBerry Bold 9650.
Sprint Airave and Magic Box
On September 17, 2007, Sprint Nextel launched the Airave, which increased cell reception over an area of 5,000 square feet (460 m 2) and could handle up to three calls at once by hooking into an existing broadband connection and using VOIP. The Airave helped eliminate poor signal quality inside buildings. Airave was used only for voice calls using a Sprint CDMA phone and was unavailable for Nextel iDEN phones or data cards/USB modems. By default, the Airave unit allowed any Sprint phone to connect through it, but it could be reconfigured to accept only connections from up to 50 authorized numbers in order to eliminate unwanted use. It should be noted that the Airrave uses the customers' own bandwidth to connect calls—potentially slowing internet speeds on less ample connections, and causing the customer to essentially subsidize the Sprint network.  That being said, Sprint is one of the only carriers that historically has not charged its customers for this type of device if the customer can demonstrate that Sprint coverage is inadequate where they live.
Airave 2.0 is a device that supports up to six devices simultaneously and data usage. The device requires a land based internet service (such as DSL or Cable Modem) to produce the CDMA signal. The Airave 2.5 improved reliability and had two LAN ports. 
Airave 3.0 is a device that broadcasts both CDMA and LTE using band 41 that was approved by the FCC in late 2016  and became available in 2017 . It requires a cable internet connection and includes a WAN RJ45 port and two RJ45 ethernet LAN ports.
The Magic Box creates its own Band 41 LTE signal and uses Band 41 or Band 25 LTE signal instead of a cable connection for internet. It is designed to be placed on a window sill and broadcasts to the inside of the building plus outside the building for 100 meters or further. 
Defunct brands and Networks
Common Cents Mobile
Sprint Nextel began offering pre-paid wireless products and services via wholly owned MVNO Common Cents Mobile on May 13, 2010. Sprint Nextel intended these products and services as a lower-cost alternative, charging $.07 per minute for voice calls with round-down timing and $.07 per text message. The products and services were initially available through Walmart stores; Sprint Nextel had planned to expand the distribution of Common Cents Mobile to other outlets, but never did. 
On May 18, 2011, Sprint Nextel discontinued operating its Common Cents Mobile pre-paid brand, on the basis it was a duplicate of the offerings of the Virgin Mobile USA PayLo brand. Common Cents Mobile customers were transitioned to a Virgin Mobile payLo service plan that allowed the former Common Cents Mobile customers to keep their existing $.07 per minute rate.   
Nextel Direct Connect
Sprint Nextel decided to decommission the iDEN (Nextel National) network it had acquired after merging with Nextel Communications in order to repurpose the network for LTE coverage; Sprint stopped offering Nextel Direct Connect walkie-talkie service. Instead, Sprint persuade many of its customers into their replacement service - Sprint Direct Connect which operates on the CDMA network.
CLEAR was the brand of mobile broadband services offered by Clearwire Corporation, which was acquired by Sprint Nextel in July 2013. The brand provided mobile and fixed wireless broadband communications services to retail and wholesale customers in Belgium, Spain and the United States. Sprint ended the CLEAR brand in September 2013 shortly after it closed its acquisition of Clearwire, and it no longer offers CLEAR branded products and services to new customers. 
Sprint Nextel operated an iDEN nationwide network in the 800 and 900 MHz SMR frequency band. Sprint Corporation acquired the iDEN network as a result of its merger with Nextel Communications in 2005. The iDEN network was originally deployed as a dispatch radio service and is unique in blending the half-duplex push-to-talk one-to-many broadcast capability of a walkie talkie with the one-to-one private communication of a phone. Sprint later marketed "push-to-talk" services under the Nextel Direct Connect name.
In October 2010, as part of the "Network Vision" plan, Sprint CEO Dan Hesse announced the decommissioning of the iDEN network to reduce costs, improve the coverage and performance of the 3G CDMA network and enable Sprint Nextel to focus on 4G LTE technology. Sprint Nextel announced on May 29, 2012, that it will stop marketing iDEN devices in the third quarter of 2012 and that the iDEN network could be completely decommissioned "as early as June 30, 2013".  As of June 5, 2012, Sprint and Boost Mobile ceased offering iDEN devices, removing the devices and their associated service plans from the Sprint and Boost Mobile websites and retail locations. The Nextel national network was shut down on schedule at 12:01am on June 30, 2013.
|Radio frequency range||Band number||Generation||Radio Interface||Status|

|900 MHz ESMR  ||N/A||2G||iDEN||Decommissioned|
Sprint Corporation operated a 4G WiMAX network in the 2.5 GHz band, which had been operated by Clearwire Corporation before it was acquired. Sprint also provided its prepay partners Boost Mobile and Virgin Mobile access to data services via the WiMAX network; including other Mobile virtual network operators under wholesale agreements.
Sprint Nextel had won rights to radio spectrum in the 2.5 GHz band to provision fourth generation services and began to build out a WiMAX network, offering services under the Xohm brand. However, on May 7, 2008, Sprint Nextel announced it would merge its WiMAX wireless broadband unit with Clearwire Corporation, receiving equity in Clearwire in return. The two companies completed the transaction on November 28, 2008.  Sprint became the owner of Clearwire, after outbidding Dish Network for the company.
On October 8, 2008, Sprint Nextel launched WiMAX in Baltimore and showed off several new laptops that will have embedded WiMAX chips. They announced that Sprint will be offering dual-mode 3G/4G products by the end of the year. Baltimore was the first city to get Xohm, but it was launched soon after in more cities, such as Chicago and Philadelphia. 
On April 19, 2011, Sprint Nextel announced it agreed to pay at least $1 billion to Clearwire so it can operate on the 4G WiMAX network through 2012, and a later agreement, announced in December 2011, specified terms allowing Sprint, its subsidiaries, and wholesale customers to continue having access to the Clearwire 4G WiMAX network through 2015. On July 9, 2013, Sprint Nextel acquired the remaining stock shares it did not already own in Clearwire and its assets.
Sprint Corporation is working on migrating WiMAX customers to LTE compatible devices in order to begin transitioning the WiMAX bands to TDD LTE. In July 2013, Sprint announced its first tri-band products capable of accessing TDD-LTE data connections in the 2.5 GHz band still used for WiMAX. 
Sprint planned to shut its WiMAX network on November 6, 2015, however an emergency injunction was granted by a judge of the Massachusetts Superior Court on November 5 to keep the WiMax network online for another 90 days, due to the ongoing lawsuit from non-profit groups. The groups, Mobile Beacon and Mobile Citizen, said that the network shutdown violates the contract which requires Sprint to provide high-speed internet services for low-income families and public institutions, as most of the equipment was still not LTE-compatible. Sprint pledged to provide upgrades to the equipment and work out a solution with the groups as soon as possible. Most of the WiMax network not running in the affected areas was shut down. On February 1, 2016, the same court declared that Sprint can proceed with the network shutdown in the remaining 75 cities. Sprint took the network of 16 cities, including New York City, offline on February 2, and closed 39 more on February 29. On March 31, the last 25 cities' networks were shut down. 
Except devices launched on or after February 15, 2015, Sprint does not authorize the use of GSM-capable devices, including both phones and tablets it sells, on a United States-based competitor's network, such as T-Mobile or AT&T.  Unlike the aforementioned companies, which have comparatively lenient policies about unlocking phones, such as when the device is paid off or the contract is fulfilled, and Verizon, whose GSM-capable devices ship with the GSM portion already unlocked, Sprint will unlock devices for international use only for customers in good standing after contacting customer support. 
This limitation means phones and tablets sold by Sprint which were launched prior to February 15, 2015 will only lawfully function on the Sprint network, a policy that prevents what may otherwise be compatibility with another carrier's network. Additionally, the resale value of Sprint-sold iPhones generally are the lowest of devices sold by the top four carriers in the country.  Means to unlock a GSM-capable iPhone exist, such as using a SIM interposer, but the device may not function fully or correctly on the desired network, and unlocking of the device had been a violation of the law under the terms of the DMCA up until August 1, 2014 when President Obama signed into law a bill allowing the unlocking of cell phones. 
Lack of SIM purchase options
Although with the launch of the LTE network, it is now technically possible to bring many third-party devices, like Nexus 5 or Nexus 6, onto Sprint's LTE network by simply inserting a provisioned SIM card from the carrier. Customers are able to purchase SIM cards directly from some stores and some phone representatives, provisioning is still being restricted to branded Sprint postpaid services and only certain postpaid plans, and is completely unavailable for its prepaid plans and brands like Virgin or Boost Mobile. Some MVNOs sell SIM cards for Sprint.  
As of December 2016, Sprint finally does have a web-page,, purchasing a SIM card online is now available, the only stores stocking cards are those with repair shop capabilities.  Meanwhile, redirects to a business offering,  and a generic BYOD/BYOP shortcut is not known.
Sprint remains the only of the four nationwide wireless carriers to not readily offer SIM card sales, where even Verizon (which like Sprint—and unlike AT&T and T-Mobile —has neither GSM nor UMTS / HSPA+ networks) does make SIM cards readily available since more than a year ago. 
FCC fine over Do Not Call rule breaches
In May 2014, the company was fined $7.5 million by the U.S. Federal Communications Commission for failing to honor consumer requests to opt out of marketing messages delivered by phone and text messages. Sprint was ordered to implement a comprehensive two-year plan to comply with the commission's rules including training of Sprint employees on how to comply with Do Not Call rules. American consumers have had the option of nominating not to receive telemarketing calls and texts since 2003, by placing their names on the National Do Not Call Registry. 
As required by law in the United States, in response to court orders and warrants, Sprint Nextel provided law enforcement agencies with its wireless subscribers' GPS locations over 8 million times in one year between September 2008 and October 2009.  The disclosures occurred by way of a special, secure portal which Sprint developed specifically for government officials, which enabled users to automatically obtain Sprint customers' GPS locations after the request has been reviewed and activated by Sprint's surveillance department.
After Sprint merged with Nextel Communications, which was ranked by Bloomberg News as one of the worst mergers for shareholder value,  Sprint implemented a social media employee engagement program called "Social Media Ninjas" in order to improve Sprint's reputation. Sprint Ninjas are employees who are trained to advocate for Sprint's products and services in their personal online networks by posting content and interacting with customers.  Sprint was awarded by the American Customer Satisfaction Index as the most improved company in customer satisfaction from 2008 to 2012.  
In 2016, Sprint began a major television advertising campaign promoting its reliability as being within 1% of other major providers, such as Verizon. The advertisements feature Paul Marcarelli, an American actor once known for pitching Verizon with the phrase "Can you hear me now?" In the ads, Marcarelli notes that he has switched to Sprint and touts pricing of approximately half that of other providers, commenting "Can you hear that?" The ads feature the slogan "Don't let a 1% difference cost you twice as much." 
Sprint cellphones were product placed in such movies such as Men in Black II (2002), The Departed (2006), Dan in Real Life (2007), Superbad (2007), Wild Hogs (2007), 27 Dresses (2008), Baby Mama (2008), Beverly Hills Chihuahua (2008), Eagle Eye (2008), The Spiderwick Chronicles (2008), Sex and the City (film) (2008), Alvin and the Chipmunks: The Squeakquel (2009), Bride Wars (2009), Transformers: Revenge of the Fallen (2009), and The Gambler (2014).
Sprint was the official wireless sponsor of the 2007 MTV Video Music Awards. Sprint Power Vision customers were able to watch the VMAs on a live simulcast on their Sprint Power Vision handset free of charge.
In Time Magazine' s November 13, 2006 issue, Sprint Nextel's NASCAR FanView was named One of Best Inventions of 2006.  The NASCAR FanView is a portable PDA that runs on Sprint's data network. The device offers fans access to "Race telecast and up to seven in-car camera channels, direct audio feeds allowing the user to listen to live driver and team conversations, as well as the radio broadcast and an exclusive audio-replay feature."
From 2008 to 2016, Sprint Corporation was the major title sponsor of NASCAR ’s top racing series, formerly called the NEXTEL Cup, which became known as the Sprint Cup Series on January 1, 2008.  Since then, Sprint signed a contract extension with NASCAR to continue sponsoring the series through the 2016 season.  Sprint was replaced by Monster Energy after the 2016 season. 
Sprint Nextel announced in December 2011 that it reached a multi-year exclusive partnership with the National Basketball Association (NBA) to be the league's official wireless service partner.
Sprint is a major sponsor of competition reality shows, such as Big Brother and Survivor on CBS, enabling viewers to vote each week for "Player of the Game". Viewers can text a vote for their selected contestant, and a randomly selected participant who votes for the most popular player wins a cash prize.
