AT&T Mobility, LLC, commonly referred to as AT&T Wireless or simply AT&T, is a U.S.-based telecommunications provider. Established in April 2000 under the name Cingular Wireless LLC, it operates as a fully owned subsidiary of AT&T Inc., delivering wireless communication services throughout the United States. With a subscriber count of 118.2 million as of June 30, 2025, AT&T Mobility holds the position of the third-largest wireless carrier nationwide.
The company’s main offices are located in Brookhaven, Georgia. Initially launched as Cingular Wireless, it was formed through a partnership between SBC Communications and BellSouth. In 2004, Cingular acquired the former AT&T Wireless. Following SBC’s acquisition of the original AT&T, the business adopted the AT&T brand name. The purchase of BellSouth in December 2006 made Cingular a wholly owned subsidiary of AT&T.
The rebranding from Cingular to AT&T took place in January 2007, with the transition finalized by June to coincide with the launch of the Apple iPhone.
On March 20, 2011, AT&T Mobility revealed its intention to purchase T-Mobile US from Deutsche Telekom for $39 billion, which would have increased its subscriber base beyond 130 million users. Nevertheless, due to opposition from regulatory bodies such as the U.S. Department of Justice and the Federal Communications Commission, along with competitors like Sprint Corporation who raised concerns about diminished market competition, AT&T withdrew its bid in December 2011.
Services
AT&T provides three variations of its Unlimited Your Way offerings: AT&T Unlimited Premium® PL, AT&T Unlimited Extra® EL, and AT&T Unlimited Starter® SL. Other plans available include AT&T Value Plus VL and AT&T 4 GB. Every plan includes unlimited calling and texting; however, unlimited data is available on all except the 4 GB option. Plans at higher tiers offer premium data access with prioritized network usage up to a specified limit per line and include features such as Mobile Hotspot capability. The Unlimited Premium® PL package additionally grants unlimited talk, text, and data usage across 20 Latin American countries without additional fees. Since January 2016, two-year contracts for subsidized smartphones have been discontinued; customers must now utilize NEXT installment plans when upgrading devices. Data speeds on unlimited plans may be throttled according to specific plan conditions.
Current subscribers can continue using legacy plans, though AT&T retains the right to mandate plan changes under its service agreements.
In regions covered by AT&T’s 21-state landline network, retail outlets offer home phone, internet access, and U-verse television services; stores located outside this footprint primarily focus on wireless products. Across all company-operated locations nationwide, DirecTV services are sold and complimentary email accounts are provided for customers.
Employees
A large segment of AT&T Mobility’s workforce is unionized through the Communications Workers of America (CWA). As of early 2006, approximately 15,000 out of the former 20,000 employees at AT&T Wireless were represented by CWA. By late 2009, union membership among AT&T Mobility personnel had grown to around 40,000.
Cingular Wireless
Cingular Wireless was created in April 2000 as a joint venture between SBC Communications and BellSouth, quickly becoming the second-largest wireless carrier in the United States. The company merged more than one hundred entities, including twelve regional Bell-originated companies such as Ameritech Mobile Communications, BellSouth Mobility, and Southwestern Bell Mobile Systems. SBC Wireless operated under the "Cellular One" brand in northeastern markets while BellSouth incorporated operations formerly managed by Houston Cellular.
The network infrastructure predominantly relied on D-AMPS technology except for Pacific Bell and BellSouth Mobility DCS divisions that utilized GSM technology on the PCS spectrum (1900 MHz). The company’s lineage can be traced back to Advanced Mobile Phone Service, an earlier subsidiary of AT&T founded in 1978.
In October 2007, Stan Sigman stepped down as CEO of AT&T Mobility and was succeeded by Ralph de la Vega, marking an important leadership transition within the organization.
AT&T Wireless merger
In February 2004, Cingular revealed plans to acquire rival AT&T Wireless Services for $41 billion, effectively more than doubling its valuation. The transaction concluded in October 2004, boosting Cingular’s subscriber count to 46 million and establishing it as the largest wireless provider in the United States. Following the merger, AT&T Wireless was rebranded as New Cingular Wireless Services.
After completing the acquisition, Cingular sold its operations in the Caribbean and Bermuda to the Irish-based Digicel Group in 2005 for around $122 million, allowing the company to concentrate on its primary markets and optimize its international footprint.
Integrating the two separate infrastructures—the AT&T "Blue" Network alongside Cingular's "Orange" Network—involved consolidating approximately 50,000 cellular towers. Each network utilized a mix of TDMA and GSM technologies. The full technical unification was accomplished in 2005 through Enhanced Network Selection (ENS), which facilitated seamless device connectivity during the transition phase.
This consolidation markedly strengthened Cingular’s market presence and competitive positioning within the U.S. wireless sector.
The New AT&T
On November 21, 2005, Ed Whitacre, then CEO of the merged SBC/AT&T entity, declared intentions to promote Cingular’s services under the AT&T brand name. Executives from BellSouth and Cingular noted that while the Cingular brand would persist—primarily focusing on business clientele—the AT&T brand would be emphasized in bundled service offerings.
On March 5, 2006, AT&T announced its merger with BellSouth, which was completed on December 29, 2006, following regulatory approval by the FCC. Subsequently, AT&T phased out the Cingular name across all services and launched a marketing campaign introducing "The New AT&T." This rebranding included incorporating orange hues into AT&T’s logo to symbolize the integration; however, this color scheme was removed in 2015 after another rebranding linked to acquiring DirecTV.
In November 2007, AT&T expanded its subscriber base by acquiring Dobson Communications for $2.8 billion, adding 1.7 million customers and enhancing coverage across suburban and rural regions, including Alaska. On November 7, 2008, AT&T announced plans to purchase Centennial Wireless for $944 million, further broadening its footprint in the Midwest, southern United States, and Puerto Rico.
Failed acquisition of T-Mobile USA
On March 20, 2011, AT&T reached an agreement to buy T-Mobile USA from Deutsche Telekom for roughly $39 billion in cash and stock, subject to regulatory consent. The deal encountered regulatory challenges from both the FCC and U.S. Department of Justice; on August 31, 2011, a lawsuit was filed to block the merger. In November 2011, FCC Chairman Julius Genachowski recommended an extended review of the acquisition. Facing mounting opposition, AT&T withdrew its application on November 23, 2011, incurring a $4 billion charge related to breakup fees and spectrum transfer commitments.
2012–present
On August 2, 2012, AT&T announced intentions to acquire NextWave Wireless. By January 2013, it pursued purchasing Atlantic Tele-Network’s U.S. retail wireless operations (Alltel) for $780 million. In June 2014, AT&T obtained assets and operations from Plateau Wireless covering eastern New Mexico and western Texas, including valuable spectrum licenses and approximately 40,000 subscribers.
During late 2014 and early 2015, AT&T broadened its international reach by acquiring Mexican carriers Iusacell and Nextel Mexico, merging them into what became AT&T Mexico.
On October 9, 2019, Liberty Latin America declared a $1.95 billion agreement to acquire AT&T Wireless Services in Puerto Rico and the U.S. Virgin Islands; this transaction closed on November 2, 2020. By mid-2021, Liberty began consolidating branding with AT&T before fully retiring the AT&T brand in September of that year.
On February 22, 2024, a major nationwide service disruption affected customers of AT&T across multiple regions.
GSM operations
Prior to Cingular's acquisition of AT&T Wireless, a joint venture called GSM Facilities facilitated a shared GSM-1900 network between Cingular and T-Mobile USA in regions including California, Nevada, Northern New Jersey, and New York City. This partnership provided local network coverage within these areas. On May 25, 2004, both companies declared their intention to terminate this arrangement upon completion of the AT&T Wireless acquisition. Consequently, the Cingular network assets were transferred to T-Mobile USA, while Cingular retained GSM infrastructure at AT&T Wireless locations.
Fiber optic switching centers
AT&T manages a Tier-1 global subsea fiber network switching hub located on St. Croix in the U.S. Virgin Islands. This facility operates in collaboration with the University of the Virgin Islands Research and Technology Park.

Coverage
AT&T maintains the second-largest digital voice and data network within the United States, supporting 4G LTE while actively deploying 5G NR technology. Building upon the foundation established by Cingular's earlier infrastructure, AT&T phased out both analog and TDMA systems by early 2008 to concentrate on GSM and UMTS platforms.
The company introduced its broadband UMTS/HSDPA network in 2005 to rival Verizon Wireless and Sprint Nextel’s EV-DO services, achieving coverage across all principal metropolitan areas by 2006. By early 2009, AT&T had completed enhancements to HSUPA technology and subsequently rolled out HSPA+, which was marketed under the "4G" label. LTE service commenced in 2011 with a gradual rollout; however, deployment pace trailed competitors, partially attributed to the pending T-Mobile USA merger.
On January 1, 2017, AT&T terminated its 2G GSM network, followed by the shutdown of its 3G UMTS network on February 22, 2022. In April 2017, the company unveiled "5G Evolution" (5G E), an advanced LTE network positioned as a transitional step toward genuine 5G connectivity.
Currently, AT&T operates the nation’s second-largest 5G network, reaching roughly 30% of the U.S. population. It leverages a combination of low-, mid-, and high-band spectrum; mid- and high-band services are marketed as "5G+" with significantly enhanced speeds. The firm aims to substantially expand its mid-band 5G+ footprint throughout 2023, targeting coverage for approximately 200 million users by year-end.
This progression underscores AT&T’s strategic approach centered on infrastructure modernization to sustain competitive positioning and secure market share within wireless communications on a global scale.
"Fewest dropped calls"
In early 2006, Telephia conducted a nationwide evaluation across 350 metropolitan areas which found that Cingular experienced the lowest rate of dropped calls. This finding prompted an assertive marketing campaign promoting the "Allover Network." Telephia claimed to perform the largest wireless network test globally, analyzing over six million calls annually and was regarded as an independent authority in wireless research. Nevertheless, these results conflicted with a Consumers Union survey featured in Consumer Reports, which criticized Cingular for dropped calls and audio interference. Furthermore, J.D. Power and Associates placed Cingular near the bottom in its 2006 Wireless Call Quality Study.
Initially withholding detailed information about the study, Telephia later clarified that although Cingular showed statistically lower dropped-call rates in select markets and timeframes, it was unaware of how Cingular derived its marketing claims. In response to this dispute, AT&T discontinued using the verbal slogan "The Fewest Dropped Calls" in advertisements but continued efforts emphasizing call dependability and minimizing call drops.
iPhone
On June 29, 2007, Apple launched its iPhone in the United States exclusively through AT&T until February 10, 2011, when Verizon began offering the iPhone 4. Early on, AT&T encountered billing challenges including highly detailed monthly statements—one notably spanning 300 pages—which drew significant media attention following exposure by YouTube personality iJustine.
The iPhone 3G debuted with AT&T on July 11, 2008. Apple announced sales exceeding one million units within three days—a dramatic acceleration compared to the original iPhone’s seventy-four days to reach one million—highlighting rapid consumer adoption. Best Buy started retailing the iPhone 3G for AT&T customers in August 2008, broadening availability. By October of that year, AT&T extended sales into Puerto Rico and the U.S. Virgin Islands.
The iPhone 4 launched on June 24, 2010, selling more than 1.7 million units during its initial days—making it the fastest-selling phone at that point—and significantly enhancing AT&T’s second-quarter financial results. The iPhone 5 followed on September 12, 2012; Apple reported five million units sold over its opening weekend. During Q4 of that year, AT&T activated approximately 8.5 million iPhones, reflecting robust demand and contributing notably to revenue growth.
Android-powered smartphones
On February 18, 2010, AT&T unveiled its inaugural Android smartphone, the Motorola Backflip, which became available on March 7, 2010. Subsequently, the carrier launched the HTC Aria on June 20, 2010, followed by the Samsung Captivate, a member of the Galaxy S series, on July 18, 2010. During the final quarter of 2010, Motorola further broadened its Android portfolio with the introduction of the Flipout, Flipside, and Bravo devices.
For the fiscal year 2011, AT&T announced plans to release three new 4G Android smartphones: the Motorola Atrix 4G, HTC Inspire 4G, and Samsung Infuse 4G. These devices operated on Android 2.2 (Froyo) initially, with anticipated updates to Android 2.3 Gingerbread and improved 4G functionality. Unlike other carriers in the U.S., AT&T initially limited users from installing applications outside the official marketplace. However, in May 2011, the company shifted its approach by permitting sideloading of unofficial apps on select existing and forthcoming Android models, signaling a strategic move aimed at enhancing user flexibility and strengthening market competitiveness.
4G LTE (Long-Term Evolution)
In 2012, AT&T launched a BBDO advertising campaign centered on promoting its 4G LTE network. Featuring Beck Bennett interviewing children with the tagline "It's not complicated," these commercials—directed by Jorma Taccone—utilized guided improvisation to emphasize the network’s speed and user-friendly nature.
Appearances in Need for Speed Games
In the transition between Need for Speed: Underground 2 and Need for Speed: Carbon, Cingular—AT&T’s previous brand identity—was featured as the in-game mobile internet service provider.
Current offerings
AT&T brought back unlimited wireless data plans in 2016, initially requiring customers to subscribe to an AT&T-owned pay TV service such as DirecTV or U-verse. By April 2017, the Unlimited Plus plan was offered at a reduced price and included HBO access through either AT&T’s pay TV platforms or HBO GO. In June 2018, these options were replaced by "Unlimited & More" plans that incorporate AT&T's "Watch TV" streaming service at no additional charge. The premium tier allows subscribers to add services like Cinemax, HBO, Showtime, Spotify, Starz, Amazon Music Unlimited, Pandora Premium, or VRV. The basic tier restricts video streaming quality to standard definition. These modifications illustrate AT&T’s strategy to merge wireless connectivity with content services to boost customer value and maintain a competitive edge.
AT&T Prepaid
AT&T Prepaid (branded as AT&T PREPAID; formerly known as GoPhone) represents AT&T Mobility's prepaid wireless service. The GoPhone brand originated in 1987 under McCaw Cellular, founded by entrepreneur Craig McCaw. After AT&T acquired McCaw in 1995, GoPhone was integrated into AT&T Wireless before Cingular Wireless purchased AT&T Wireless for $41 billion in 2004. At that time, Cingular was jointly owned by SBC Communications (60%) and BellSouth.
Following this acquisition, Cingular discontinued the original GoPhone service but retained the brand name for its prepaid products until it was rebranded as AT&T PREPAID in 2017. By January 2019, AT&T Prepaid had amassed around 6 million subscribers, underscoring its prominent position within the prepaid market segment.
NumberSync
Introduced in 2015, NumberSync expands AT&T’s offerings by enabling postpaid subscribers to utilize a single phone number across various gadgets—such as smartphones, tablets, and wearables—ensuring smooth synchronization of calls and text messages. This feature aligns with AT&T’s objective to boost customer loyalty through unified device connectivity.
Slogans of AT&T
- "Your World. Close At Hand." (1999)
- "What do you have to say?" (2000–2002)
- "Fits you best" (Cingular Wireless) (2002–2004)
- "Raising the bar" (Cingular Wireless) (2004–2006)
- "More bars, In More places" (2006–2007)
- "Your world. Delivered" (2007–2010)
- "Rethink possible" (2010–2014)
- "Mobilizing Your World" (2014–2017)
- "Entertainment Your Way" (2017)
- "More For Your Thing, That's Our Thing" (2018–present)
Mislabeling as 4G (LTE)
Beginning in 2011, following T-Mobile USA’s lead, AT&T started promoting its HSPA and HSPA+ networks as "4G," accompanied by updates to device software to display this classification. Although the ITU had broadened the 4G definition to incorporate HSPA+, the original HSPA standard did not fulfill 4G criteria, and devices lacking Evolved HSPA capabilities were incapable of achieving HSPA+ speeds. This marketing tactic faced widespread criticism for being misleading and raised concerns about potential confusion when authentic 4G VoLTE services became available.
Mislabeling as 5G
In 2017, AT&T launched the 5G Evolution (5G E) trademark to describe LTE networks enhanced with LTE Advanced and Pro technologies such as 4x4 MIMO and 256-QAM modulation, boasting theoretical maximum speeds up to 400 Mbit/s. Network indicators on devices were updated via software to show "5G E." Nevertheless, this branding does not correspond with official 5G standards; AT&T presented it as a transitional phase toward true 5G, focusing on enhanced performance rather than actual technology compliance, marketing it as "The First Step to 5G."
This branding drew accusations of consumer deception by rebranding advanced LTE networks as 5G. While competitors like T-Mobile and Verizon also promoted similar network enhancements, they labeled them as improved 4G LTE rather than 5G. T-Mobile openly criticized AT&T’s strategy. Industry analysts pointed out that other carriers’ designations—for example, Claro’s "4.5G"—were less likely to cause confusion.
Sprint filed a lawsuit against AT&T in February 2019 over the "5G E" trademark, alleging false advertising and consumer misunderstanding regarding network capabilities compared to genuine 5G. The dispute was eventually resolved with an agreement permitting AT&T to continue using the trademark.
Following complaints from T-Mobile, the National Advertising Review Board in May 2020 recommended that AT&T discontinue use of the terms "5G Evolution" and related slogans in marketing materials due to possible consumer confusion. AT&T consented to halt these phrases in advertisements but retained the right to display the "5G E" logo on devices.
NASCAR sponsorship dispute
Cingular Wireless began sponsoring the #31 Chevrolet car fielded by Richard Childress Racing in NASCAR's Winston Cup Series in 2002. After Nextel Communications (now Sprint Corporation) acquired naming rights for NASCAR's premier series in 2004, Cingular and Alltel, which sponsored the #12 Dodge driven by Ryan Newman for Penske Racing, were allowed to continue under a grandfather clause. When AT&T acquired Cingular in early 2007 and planned a rebrand to AT&T Mobility, NASCAR enforced the Viceroy rule, prohibiting changes in team names or branding on the #31 car.
After NASCAR refused permission for AT&T branding on the vehicle, AT&T initiated legal action against NASCAR on March 16, 2007. On May 18, a preliminary injunction was granted in favor of AT&T, permitting rebranding of Jeff Burton’s #31 car for the Nextel All-Star Challenge. NASCAR appealed this decision and filed a $100 million countersuit on June 17 seeking to exclude AT&T and competing telecom sponsors from NASCAR events in 2008.
The United States Court of Appeals for the Eleventh Circuit ruled on August 13 supporting NASCAR’s position, allowing them to block AT&T branding on the car. By August 24 at Bristol Motor Speedway, the #31 car competed without primary sponsor logos; associate sponsors remained visible but no AT&T branding was present. NASCAR rejected two alternative paint schemes proposed by AT&T—one featuring its "Go Phone" brand and another reviving Cingular’s slogan "more bars in more places"—though NASCAR later denied having rejected these designs outright.
A settlement reached on September 7, 2007 permitted AT&T Mobility sponsorship of the #31 car through the end of 2008; sponsorships at lower levels like the Nationwide Series were unaffected.
Since this dispute, no division of AT&T has returned as a NASCAR sponsor. The Viceroy rule's focus shifted from telecommunications companies toward beverage sponsors when Monster Energy became Cup Series sponsor in 2017; later, NASCAR eliminated title sponsorship altogether—lifting many restrictions on team sponsorships subject to approval. It is notable that previously, AT&T's parent company had been involved in litigation against a NASCAR team and driver it sponsored over performance-related issues.
Throttling of "unlimited" plans
In 2012, AT&T came under fire for reducing data speeds on unlimited plans, claiming it had the contractual authority to slow service after users exceeded certain data limits. That same year, Matt Spaccarelli succeeded in a small claims court case, receiving $850 after his service was intentionally slowed; the court determined that the term "unlimited" should not be interpreted to allow speed reductions. Additionally, AT&T's user agreement restricts customers from initiating class-action lawsuits against the company.
The Federal Trade Commission took legal action against AT&T in 2014, accusing the company of deceptive throttling practices. By 2019, AT&T reached a $60 million settlement, agreeing to provide partial reimbursements to impacted customers and to transparently disclose any future throttling policies on its wireless offerings.
Mobility Administrative Fee
Beginning in May 2013, AT&T implemented a monthly "Mobility Administrative Fee" of $0.61 for each postpaid wireless line, including those under contract. This charge, listed separately on billing statements, brings in over $500 million annually and is intended to cover expenses related to cell tower infrastructure and upkeep. In June 2018, the fee was raised to $1.99 per line, potentially increasing annual revenue by approximately $800 million.
Illegal location data sharing
In April 2024, the Federal Communications Commission imposed a $57 million penalty on AT&T for unlawfully distributing customers' real-time location information. AT&T contested the FCC’s decision, asserting that the ruling lacked both legal and factual justification.
