AT&T; Mobility LLC is a wholly owned subsidiary of AT&T; Inc. that provides wireless services to 110.6 million subscribers in the United States, Puerto Rico and the U.S. Virgin Islands. AT&T; Mobility is the largest wireless telecommunications provider in the United States ahead of Verizon Wireless, which has 97.9 million customers as of the second quarter of 2011. AT&T; Mobility is headquartered in the Lenox Park area of DeKalb Co. Georgia, just outside Atlanta.
Originally Cingular Wireless LLC, a joint venture between SBC Communications and BellSouth, the company acquired the old AT&T; Wireless in 2004; SBC later acquired the original AT&T; and re-branded as "The New AT&T;". Cingular became wholly owned by AT&T; in December 2006 as a result of AT&T;'s acquisition of BellSouth.
In January 2007, Cingular confirmed it would re-brand itself under the AT&T; name. Although the legal corporate name change occurred immediately, for both regulatory and brand-awareness reasons both brands were used in the company's signage and advertising during a transition period. The transition concluded in late June, just prior to the rollout of the Apple iPhone.
On March 20, 2011, AT&T; Mobility announced its intention to acquire T-Mobile USA from Deutsche Telekom for $39 billion. If AT&T; receives government and regulatory approval, AT&T; will have more than 160 million subscribers.
SBC Wireless had previously operated in several northeast markets under the "Cellular One" brand, while BellSouth's wireless operations incorporated the former Houston Cellular.
Cingular's lineage can be traced back to Advanced Mobile Phone Service, which was a subsidiary of AT&T; created in 1978 to provide cellular service nationwide. AMPS, Inc. was divided among the Regional Bell Operating Companies as part of the Bell System divestiture.
With the exception of Pacific Bell and BellSouth Mobility DCS, the digital network consisted of D-AMPS technology. The Pacific Bell and BellSouth Mobility DCS networks used GSM technology on the PCS frequency band (1900 MHz).
In October 2007, AT&T;’s president and chief executive officer Stan Sigman announced his retirement. Ralph de la Vega, group president-Regional Telecom & Entertainment, was named as president and CEO, AT&T; Mobility.
The merger was completed on October 26, 2004. The combined company had a customer base of 46 million people at the time, making Cingular the largest wireless provider in the United States. AT&T; Wireless was then legally renamed New Cingular Wireless Services, Inc. Shortly after, new commercials were shown with the "AT&T;" transforming into the Cingular logo, and with the Cingular logo's text turned blue to acknowledge the change. First announced on June 22, 2005, Cingular Wireless announced the intention to divest its Caribbean and Bermuda operations and licenses which it acquired from the acquisition of AT&T; Wireless, to Irish-owned and Jamaica-based Digicel Group under undisclosed financial terms.
In 2006, one year following the deal, a high ranking source allegedly close to the sale pointed the Barbados Daily Nation Newspaper towards some SEC filings made by Cingular which were said to establish an idea of the approximate sale price of the deal. According to the SEC filings Cingular was paid around US$122 million, with much of that $122m cost to Digicel going towards the purchasing of the former AT&T; Wireless assets in Barbados.
At the time of the merger, there were two networks: the historic AT&T; Blue Network and the Cingular Orange Network. Both networks contained a mix of both TDMA and GSM facilities. Approximately 50,000 cell sites had to be melded together. From a technical standpoint, the "blue" and "orange" networks were considered different networks until integration was completed in 2005. Enhanced Network Selection (ENS) was used to home cellular devices on either the "blue" or "orange" network during this process.

Cingular, the predecessor to AT&T; Mobility, supported legacy D-AMPS/TDMA and analog wireless networks. In March 2006, Cingular announced that these networks would be shut down by February 2008. As of March 31, 2007 Cingular ended TDMA supported for GoPhone (pre-paid) customers. On February 18, 2008, AT&T; Mobility officially ended service on their AMPS and TDMA network, except for in areas previously operated by Dobson Communications; the Dobson AMPS and TDMA network was shut down March 1, 2008.
Networks formerly operated by AT&T; Mobility predecessors including Cingular also include various paging services and the Cingular Interactive division, which became Velocita Wireless. Velocita was later purchased by Sprint Nextel.
The AT&T; Mobility wireless data network began in 2002 as a Cingular initiative called "Project Genesis" that involved a GPRS (General Packet Radio Service) overlay of the entire wireless network. Project Genesis was completed by the end of 2004. Later, this network was upgraded to EDGE (Enhanced Data rates for GSM Evolution) across the GSM footprint.
In 2005, AT&T; Mobility launched a broadband network known as "BroadbandConnect," based on UMTS and High-Speed Downlink Packet Access (HSDPA), to counter Verizon Wireless and Sprint's EV-DO networks. UMTS service was launched on December 6, 2005 in Seattle, Portland, San Francisco, Salt Lake City, San Jose, San Diego, Las Vegas, Phoenix, Puerto Rico, Austin, Houston, Dallas, Detroit, Chicago, Boston, Baltimore and Washington D.C. and expanded to all major metropolitan markets by the end of 2006. As of early 2009, AT&T; Mobility has completed its upgrade of the 3G network to HSUPA, and will begin a new round of upgrades to the HSPA+ standard.
Designed to be backwards-compatible with GSM and HSPA, LTE incorporates Multiple In Multiple Out (MIMO) in combination with Orthogonal Frequency Division Multiple Access (OFDMA) in the downlink and Single Carrier FDMA in the uplink to provide high levels of spectral efficiency and end user data rates exceeding 100 Mbit/s, coupled with major improvements in capacity and reductions in latency. LTE will support channel bandwidths from 1.25 MHz to 20 MHz and both FDD and TDD operation. MetroPCS has activated the first LTE network, which is fully operational. AT&T; Mobility has not set an official date to begin building their LTE network. Depending on the amount of spectrum the carrier deploys it is expected AT&T; will deploy 10 MHz = 70 Mbit/s.
AT&T; has noted that they will begin their upgrade to HSPA 14.4 as a part of their effort to enhance their 3G wireless network as well as the transition to LTE. AT&T; has stated that their upgrades will be complete at the end of 2010 after backhaul connections leading from cell sites to AT&T; switching facilities . In addition, AT&T; has stated that their LTE network will be completed by year end 2013.
However, AT&T;, Inc. announced on March 5, 2006 that it would acquire BellSouth. The acquisition was finalized on December 29, 2006 when the FCC gave its final approval. According to AT&T;, the company began the rebranding of Cingular Wireless to "AT&T;".
On January 12, 2007 AT&T; announced a major rebranding transition campaign to transition Cingular to the new AT&T; ("in February 2009 "new" was removed). The former Cingular stores, after being rebranded to AT&T;, sold all AT&T; products and services: wireless, landline, Internet, U-Verse, and more.
Cingular to AT&T; Rebranding Transition:
On March 20, 2011, AT&T; and Deutsche Telekom announced that AT&T; had agreed to acquire T-Mobile USA from Deutsche Telekom in a deal estimated to be worth $39 billion in cash and stock. AT&T; said the deal is expected to close in 12 months and is subject to regulatory approval. As of June 2011, it is being examined by the FCC. On August 31, 2011, the United States Department of Justice formally announced that it had filed a lawsuit to block the merger.
Telephia, which tests wireless networks by making over 6 million calls per year in what it claims is the world's largest wireless network test program, initially refused to provide details on its study, and a spokesman for the company has said, according to the Boston Globe, that "Cingular shouldn't have even mentioned the company's name to a reporter." The research company later stated that Cingular did indeed have a "statistically-significant lower dropped-call rate than the competition across some market/time period groupings", but that Telephia had "no knowledge of the specific methodology (markets, time periods or statistical thresholds) that Cingular used for its 'lowest dropped call' claim." While AT&T; has abandoned its verbal claim of "The Fewest Dropped Calls" in its commercials, it continues to show situations where two persons are speaking with each other on their phones, and one of the users' call drops. AT&T; now states "We are still continuing to run ads that emphasize the importance of not dropping calls. That campaign is continuing.
Teething problems with AT&T;'s billing process emerged soon after the iPhone's release, as early adopters started receiving exceptionally detailed monthly telephone bills with one of the most notable being the 300-page iPhone bill that was featured in an online video by blogger Justine Ezarik.
Apple launched the iPhone 3G with AT&T; on July 11, 2008. Although specific AT&T; sales numbers are unavailable, Apple announced that over 1 million iPhone 3G devices were sold during the first three days – in contrast, according to Steve Jobs, Apple’s CEO, “It took 74 days to sell the first one million original iPhones." In August 2008, Best Buy announced that it would begin selling the iPhone 3G for use on the AT&T; network. In September 2008, AT&T; announced that it would also sell the iPhone 3G in Puerto Rico and the US Virgin Islands.
In the United States, the iPhone 3G is available for purchase with or without an AT&T; contract, as most big box retailers, like Best Buy, will gladly sell it sans contract. AT&T; is rumored to have heavily subsidized the iPhone's price to reach a broader spectrum of consumers.
On December 27, 2009 reports began to surface that AT&T; had suspended online sales of the iPhone. Spokesman Fletcher Cook said that the phone company periodically "modifies" its distribution channels, but had no further comment on the suspension of sales in the New York City area. One AT&T; employee incorrectly stated that, "New York wasn't ready for the iPhone," and that it lacked a sufficient number of cell towers to meet the heavy data demands imposed upon the network by iPhone users. Sales of the popular iPhone resumed December 30, 2009. This incident has revived speculation that AT&T;'s wireless network is not up to the demands of the current generation of 3G smartphones. The official AT&T; statement is that a large amount of fraudulent activity caused the withdrawal of sales in the area.
The latest version of the iPhone is called the iPhone 4. It was released June 24, 2010. It brought a number of new features like an upgraded camera, flash, a new exterior design, upgraded screen, and the new version of Apple's software. According to Apple, over 1.7 million iPhone 4s were sold in the first few days, which is the most out of any phone ever sold. These sales propelled AT&T; to strong Q2 results.
As of July 17, 2011 AT&T; and Asurion announced that the Apple iPhone will be insurable with their Mobile Protection Pack service.
After trying and failing to persuade NASCAR to approve the addition of the AT&T; globe logo to the rear of the car, AT&T; filed a lawsuit against NASCAR on March 16, 2007. On May 18, AT&T; won a preliminary injunction in the United States District Court for the Northern District of Georgia in Atlanta and, following a failed emergency motion for a stay by NASCAR on May 19, re-branded the #31 car, now driven by Jeff Burton, in time for the Nextel All-Star Challenge that evening. NASCAR was later granted an appeal to be heard on August 2.
On June 17, NASCAR announced it had filed a US$100 million dollar lawsuit against AT&T; and would like AT&T; and all other telecommunications companies out of the sport in 2008.
On August 13, a ruling by the United States Court of Appeals for the Eleventh Circuit cleared the way for NASCAR to prevent AT&T; Inc. from featuring its logo on the car. The 11th Circuit threw out a lower court's ruling that prevented NASCAR from stopping AT&T;'s plans. The appeals court remanded the case to the district court.
At first practice for the Sharpie 500 at Bristol Motor Speedway on August 24, the #31 car was colored orange and black, but was bare; that is, no primary sponsor (but associate sponsors appeared) were on the car, similar to Formula One cars run in races where tobacco advertising was prohibited. The pit crew wore grey Richard Childress Racing shirts and Burton had a plain orange fire suit with associate sponsors. The car which carried a "subliminal advertising" scheme arrived in a black hauler with only the number 31 on the side. NASCAR officials said the car would not have made it through inspection with the AT&T; logos. During that weekend, AT&T; claimed that two alternate paint schemes proposed by AT&T;—one advertising its "go phone" and another with the old Cingular slogan "more bars in more places" that AT&T; recently brought back—were rejected by NASCAR. The Go Phone scheme had been used in the past. NASCAR later denied these claims.
The car remained bare on race night on August 25, although ESPN aired the AT&T; logo during shots from its in-car camera. Fox Sports had done so earlier in the dispute, with the words "Cingular is the new AT&T;" on-screen during these shots.
On September 7, 2007, a settlement was reached where AT&T; Mobility could remain on the #31 car until the end of 2008, but the associate sponsorship of the #29 Nationwide Series Holiday Inn Chevrolets not affected because they are in lower series.
Richard Childress Racing announced the AT&T; Mobility sponsorship will move to Grand American Road Racing Association sportscar racing in 2009 with the sponsorship of the Childress-Howard Motorsports #4 AT&T; Pontiac Daytona Prototype sportscar. Childress is a part-owner of this team.
If the planned acquisition of T-Mobile USA is completed, AT&T; will be the largest network provider in the U.S., with 129.2 million subscribers, overtaking Verizon Wireless with 101.1 million subscribers.
