Cingular Wireless was founded in 2000 as a joint venture of SBC Communications and BellSouth.{{cite web|url=http://www.cingular.com/about/company_overview|access-date=September 23, 2021|title=Cingular – About Us|url-status=dead|archive-url=https://web.archive.org/web/20060117060711/http://www.cingular.com/about/company_overview|archive-date=January 17, 2006|df=mdy-all}} The joint venture created the nation's second-largest carrier. Cingular grew out of a conglomeration of more than 100 companies,{{cite web|url=http://edgar.secdatabase.com/2323/95014404001647/filing-main.htm |title=CINGULAR WIRELESS LLC, Form 10-K, Annual Report, Filing Date Feb 24, 2004 |publisher=secdatabase.com |access-date =May 14, 2018}} including 12 well-known regional companies with Bell roots. The 12 companies included:

• Three companies spun off from Advanced Mobile Phone Service
• Ameritech Mobile Communications
• BellSouth Mobility
• Southwestern Bell Mobile Systems
• BellSouth Mobility DCS
• BellSouth Wireless Data
• CCPR Services d/b/a Cellular One of Puerto Rico and U.S. Virgin Islands
• Pacific Bell Wireless
• Pacific Bell Wireless Northwest
• SBC Wireless
• SNET Mobility
• Southwestern Bell Wireless

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 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 of AT&T Mobility.{{cite web|url=http://www.ceoworld.biz/?p=68 |title=CEOWORLD magazine |access-date=February 9, 2017 |url-status=dead |archive-url=https://web.archive.org/web/20071026012723/http://www.ceoworld.biz/?p=68 |archive-date=October 26, 2007 }}

In February 2004, after a bidding war with Britain's Vodafone Plc (at the time a part-owner of Verizon Wireless), Cingular announced that it would purchase its struggling competitor, AT&T Wireless Services, for $41 billion. This was more than twice the company's trading value.

{{plain image with caption|AT&T Wireless logo.svg|width=150px|caption=AT&T Wireless logo, 1987–2005}}

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.Pennsylvania Bulletin [http://www.pabulletin.com/secure/data/vol36/36-35/1740.html Doc. No. 06-1740] 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. Some of the companies that comprised Cingular, such as BellSouth Mobility, ceased to exist when they were legally merged into the operating company subsidiary AT&T Wireless PCS, which was New Cingular Wireless PCS.{{citation needed|date=November 2017}}

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.[http://www.caribbeannetnews.com/2005/06/23/acquire.shtml Caribbean Net News "Digicel to acquire Cingular's Caribbean wireless operations", June 23, 2005] {{webarchive|url=https://web.archive.org/web/20060218141120/http://www.caribbeannetnews.com/2005/06/23/acquire.shtml |date=February 18, 2006 }}[http://www.caribbeannetnews.com/2005/06/24/denies.shtml Caribbean Net News "Cingular denies leaving Caribbean because of losses or poor performance", June 23, 2005] {{webarchive|url=https://web.archive.org/web/20051202140923/http://www.caribbeannetnews.com/2005/06/24/denies.shtml |date=December 2, 2005 }}[http://www.caribbeannetnews.com/2005/06/24/awaits.shtml Caribbean Net News "Digicel awaits regulatory approval from Caribbean territories", June] {{webarchive|url=https://web.archive.org/web/20060218140907/http://www.caribbeannetnews.com/2005/06/24/awaits.shtml |date=February 18, 2006 }}[http://www.caribbeannetnews.com/2005/12/21/over.shtml Caribbean Net News "Digicel officially takes over Cingular in Barbados", December 21, 2005] {{webarchive|url=https://web.archive.org/web/20060404064940/http://www.caribbeannetnews.com/2005/12/21/over.shtml |date=April 4, 2006 }}

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 $122 million, with much of that cost going towards the purchase of the former AT&T Wireless assets in Barbados by Digicel.{{Citation needed|date=August 2007}}

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.{{cite news |url=http://www.seattlepi.com/business/204374_cingularqa20.htm |title=AT&T Network and Cingular Really Separate Networks }} {{Dead link|date=January 2012|bot=RjwilmsiBot}} Enhanced Network Selection (ENS) was used to home cellular devices on either the "blue" or "orange" network during this process.

On November 21, 2005, Ed Whitacre, then CEO of the newly merged SBC/AT&T, announced plans to market Cingular's service under the AT&T brand. BellSouth spokesman Jeff Battcher countered that the terms of the joint venture allow either party to sell the service under another name, and that he believes they will be using the brand to market to business customers.[http://www.redherring.com/Article.aspx?a=14568&hed=Cingular+to+Become+AT%26amp%3BT Redherring.com] {{webarchive|url=https://web.archive.org/web/20060325143840/http://www.redherring.com/Article.aspx?a=14568&hed=Cingular+to+Become+AT&%3BT |date=March 25, 2006 }} Cingular president Stan Sigman concurred with BellSouth's position, indicating that the Cingular brand would continue but be sold under the AT&T brand where offered in packages with other AT&T services, such as data and wireline telephony.

However, AT&T announced on March 5, 2006, that it would acquire BellSouth.{{cite web|url=http://att.sbc.com/gen/press-room?pid=4800&cdvn=news&newsarticleid=22140|title=AT&T Press Release Headlines & News from AT&T|access-date=July 25, 2016}} The acquisition was finalized on December 29, 2006, when the FCC gave its final approval. The following month, AT&T announced that it would phase out the Cingular brand across all of its services and replace it with AT&T, with an accompanying advertising campaign branding the combined company as "The New AT&T." Commercials featured the orange Cingular "Jack" logo encircling the AT&T globe logo several times, dragging its blue bars behind it to form the globe's blue stripes, before finally disappearing behind it, being backed by the chorus of the Oasis song "All Around the World". AT&T added the color orange to its signage to reflect the change;{{cite web|url=https://www.nytimes.com/2006/12/30/business/30tele.html|title=BellSouth and AT&T Close Deal|date=December 30, 2006|work=The New York Times|access-date=July 25, 2016}}{{cite web|url=https://www.nytimes.com/2007/01/12/technology/12phone.html|title=AT&T Prepares to 'De-Brand' the Cingular Wireless Name|date=January 12, 2007|work=The New York Times|access-date=July 25, 2016}} AT&T would eventually remove orange in 2015 following another rebranding related to its acquisition of DirecTV.

In November 2007, AT&T acquired Dobson Communications, who owned Cellular One and was a roaming partner of AT&T, for $2.8 billion. The sale added 1.7 million subscribers and expanded AT&T coverage in various suburban and rural markets (including Alaska).{{Cite web|url=https://www.informationweek.com/att-gains-17-million-wireless-subscriber/203101769|title=AT&T Gains 1.7 Million Wireless Subscribers In Dobson Deal|website=InformationWeek|date=November 16, 2007|language=en|access-date=2019-01-08}}{{Dead link|date=July 2023 |bot=InternetArchiveBot |fix-attempted=yes }} On November 7, 2008, AT&T announced its intent to acquire Centennial Wireless for $944 million, expanding its coverage in the Midwest, southern U.S., and Puerto Rico.{{Cite web|url=https://www.networkworld.com/article/793448/wireless-at-t-spends-944-million-to-acquire-centennial-communications.html|title=AT&T spends $944 million to acquire Centennial Communications|last=Reed|first=Brad|date=2008-11-10|website=Network World|language=en|access-date=2019-01-08}}

In California, Nevada, Northern New Jersey and New York City, Cingular and T-Mobile USA maintained and shared a GSM-1900 network prior to the acquisition of AT&T Wireless, through a joint venture known as GSM Facilities. The network sharing agreement allowed Cingular to offer local service in northern New Jersey and New York City and T-Mobile USA to offer service in California and Nevada. On May 25, 2004, Cingular and T-Mobile USA announced their intention to dissolve the agreement contingent on Cingular's successful acquisition of AT&T Wireless, the Cingular network was transferred to T-Mobile USA, with Cingular continuing work on the GSM facilities at AT&T Wireless sites.{{cite news| url=http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2004/11/01/BUGTK9HFFK1.DTL | work=The San Francisco Chronicle | title=Cingular services up in air / Customers await effects of merger with AT&T Wireless | first=Todd | last=Wallack | date=November 1, 2004}}

The following chart lists the networks that AT&T previously operated.

As a result of its formation through mergers and acquisitions, as well as the rapid technological change in the wireless industry, AT&T operates the second-largest digital voice and data network within its United States footprint. AT&T's network footprint supports 4G and uses LTE/LTE-Advanced for simultaneous packet switched voice and data communications. AT&T is also in the process of rolling out its 5G network based on the NR specification.

Cingular, the predecessor to AT&T, 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 July 15, 2007, AT&T TDMA on 1900 MHz was retired, while TDMA on 850 MHz remained. On February 18, 2008, AT&T Mobility officially ended service on their AMPS and remaining 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 predecessors including Cingular also include various paging services and the Cingular Interactive division, which became Velocita Wireless. Velocita was later purchased by Sprint Nextel.{{cite web|url=http://www2.sprint.com/mr/news_dtl.do?id=10500|title=Sprint – Tariffs|access-date=February 9, 2017}} AT&T also offered Enhanced Push To Talk (PTT) services on smartphones. The original PTT service was sunset.

The AT&T wireless data network began in 2002 as a Cingular initiative called "Project Genesis" that involved a GPRS overlay of the entire wireless network. Project Genesis was completed by the end of 2004. Later, this network was upgraded to EDGE across the GSM footprint.

In 2005, AT&T launched a broadband network known as "BroadbandConnect", based on UMTS and 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 to HSUPA,{{cite web |url=http://www.engadgetmobile.com/2008/05/22/atandt-closing-in-on-completion-of-hsupa-upgrade/ |title=AT&T closing in on completion of HSUPA upgrade – Engadget |publisher=Engadgetmobile.com |access-date=May 15, 2012 |archive-date=June 19, 2009 |archive-url=https://web.archive.org/web/20090619162308/http://www.engadgetmobile.com/2008/05/22/atandt-closing-in-on-completion-of-hsupa-upgrade/ |url-status=dead }}

During the first quarter of 2006, Telephia reported that during an extensive nationwide test of major wireless carriers in 350 metropolitan markets around the country, Cingular dropped the fewest calls across the country. In turn, Cingular began aggressively advertising the "Allover Network", citing Telephia as "the leading independent research company." Telephia's report was in stark contrast to the Consumers Union publication, Consumer Reports, based on a survey of 50,000 of its members in 18 cities, which criticized Cingular for static and dropped calls.{{cite news | url=http://www.consumerreports.org/cro/electronics-computers/cell-phones-service/cell-phone-service-1-07/overview/0107_serve_ov_1.htm | title=Best cell service | work=Consumer Reports | publisher=Consumers Union of U.S. | date=January 2007 | access-date=March 13, 2007| archive-url= https://web.archive.org/web/20070315002555/http://www.consumerreports.org/cro/electronics-computers/cell-phones-service/cell-phone-service-1-07/overview/0107_serve_ov_1.htm| archive-date= March 15, 2007 | url-status= live}} Furthermore, J.D. Power and Associates consistently ranked Cingular at or near the bottom of every geographical region in its 2006 Wireless Call Quality Study, which is based on a smaller survey of 23,000 wireless users. This campaign had to come to an abrupt end.

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."{{cite news | first=Bruce | last=Mohl | url=http://www.boston.com/business/articles/2006/04/23/the_fewest_dropped_calls/?page=1 | title=The fewest dropped calls | work=Boston Globe | publisher=The New York Times Company|date=April 23, 2006 | access-date=April 27, 2006}} 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."{{cite news | first=Ken | last=Belson | url=https://www.nytimes.com/2006/05/03/business/media/03adco.html?ex=&en=b376483a9562df2b&ei=5088&partner=rssnyt&emc=rss | title=Best Cellphone Company?

AT&T now states "We are still continuing to run ads that emphasize the importance of not dropping calls.

AT&T Prepaid (stylized AT&T PREPAID; formerly GoPhone) is a prepaid mobile phone service from AT&T Mobility.

The GoPhone name and product were originally conceived and implemented by McCaw Cellular by its founder Craig McCaw and first used in commerce in 1987 by his company. It was later bought by AT&T in 1995 and used by the pre-2004 "AT&T Wireless" after Cingular's purchase of AT&T Wireless in 2004 for $41 billion.Rohde, Laura, [http://www.pcworld.com/article/114799/article.html "Cingular Buys AT&T Wireless"] {{Webarchive|url=https://web.archive.org/web/20200919034237/https://www.pcworld.com/article/114799/article.html |date=September 19, 2020 }}, PC World, IDG News Service, Feb 17, 2004 At that time, Cingular was jointly owned by SBC Communications (Southwestern Bell Corporation) of San Antonio, Texas, which owned 60 percent, and BellSouth of Atlanta, Georgia.

The original GoPhone service was discontinued and Cingular renamed its prepaid services under GoPhone. The GoPhone brand name was still in use even after "Cingular" renamed itself "AT&T Mobility" until 2017 when it was rebranded AT&T PREPAID.{{Cite web|url=https://www.att.com/esupport/article.html#!/wireless/KM1216661|title=AT&T GoPhone is now AT&T PREPAID|website=att.com|language=en|access-date=2018-05-31}}

In 2017, AT&T began to similarly use the trademark 5G Evolution (5G E) to refer to LTE networks upgraded to support higher data speeds via LTE Advanced and LTE Advanced Pro features, such as 4x4 MIMO antennas, 256-QAM, and three-way carrier aggregation. AT&T promotes these networks as having a theoretical top speed of 400 Mbit/s.{{Cite web|title=Apple just endorsed AT&T's fake 5G E network|url=https://www.theverge.com/2019/2/4/18211044/apple-att-5g-e-network-icon-iphones-misleading-ios-software-update-beta|last=Gartenberg|first=Chaim|date=2019-02-04|website=The Verge|access-date=2019-02-05}}{{Cite web |url=https://www.theverge.com/2017/4/25/15425414/att-5g-evolution-network-lte-advanced-misleading-marketing |title=AT&T announces it will build a fake 5G network |last=Gartenberg |first=Chaim |date=2017-04-25|website=The Verge |access-date=2018-12-21}}{{Cite web |url=https://www.rcrwireless.com/20180422/wireless/att-grows-gigabit_LTE-based_5G_Evolution-tag41|title=AT&T grows its gigabit LTE-based 5G Evolution|date=2018-04-22|website=RCR Wireless News|language=en-US|access-date=2018-12-21}} In late-2018, AT&T distributed phone software patches changing network indicators to refer to these networks as such.{{Cite web |url=https://www.theverge.com/2018/12/21/18151764/att-5g-evolution-logo-rollout-fake-network |title=AT&T will put a fake 5G logo on its 4G LTE phones |last=Kastrenakes|first=Jacob |date=2018-12-21|website=The Verge |access-date=2018-12-21}}{{Cite web |url=https://www.engadget.com/2018/04/20/att-5g-evolution-new-markets/ |title=AT&T switches on its pseudo-5G in over 100 locations |website=Engadget |date=April 20, 2018 |language=en|access-date=2018-12-21}}

5G Evolution is entirely unrelated to actual 5G wireless standards; AT&T states that these technologies "serve as the runway to 5G by boosting the existing LTE network and priming it for the future of connectivity",{{Cite news|url=https://www.washingtonpost.com/brand-studio/wp/2018/12/14/the-dawn-of-the-5g-world/|title=The dawn of the 5G world |newspaper=The Washington Post|language=en|access-date=2018-12-21}} and argued that "the customer doesn't need to think about the exact technology – they only care on the performance and what it enables."{{cite web |url=https://www.anandtech.com/show/13665/qualcomm-day-1-live-blog-starts-at-2pm-et |title=Qualcomm Tech Summit, Day 1 Live Blog (Starts at 2pm ET) |work=Anandtech |access-date=2018-12-21}} AT&T marketing likewise promotes this network with the slogan "The First Step to 5G".{{Cite web|title=AT&T won't remove fake 5G logo even after ad board says it's misleading|url=https://www.theverge.com/2020/5/20/21265048/att-5g-e-misleading-advertising-recommendation-narb|last=Statt|first=Nick|date=2020-05-20|website=The Verge|language=en|access-date=2020-05-21}}

AT&T once again faced allegations that the branding was misleading, because it is merely a rebranding of existing 4G networks in order to ride upon consumer anticipation of actual 5G technology.{{cite web|author=Roger Cheng |url=https://www.cnet.com/news/at-t-brings-5g-evolution-not-real-5g-to-117-more-markets/ |title=AT&T brings '5G Evolution' (not real 5G) to 117 more markets |publisher=CNET |date=2018-04-19 |access-date=2018-12-21}}{{cite web|author=Mike Dano |url=https://www.fiercewireless.com/wireless/at-t-defends-use-5g-evolution-branding-for-lte-service-promises-theoretical-speeds-up-to-1 |title=AT&T defends use of '5G Evolution' branding for LTE service, promises theoretical speeds up to 1 Gbps this year |website=Fierce Wireless |date=2017-04-26 |access-date=2018-12-21}} T-Mobile US and Verizon Wireless have deployed similar late-stage upgrades in a larger number of markets than AT&T, but promote them as being upgrades to their 4G LTE service.

In February 2019, Sprint Corporation sued AT&T Mobility for false advertising, presenting evidence that consumers were being misled into believing these services were of equal or higher performance than actual 5G networks. Sprint sought an injunction to halt AT&T's promotion of the network with this trademark.{{Cite web|url=https://www.theverge.com/2019/2/8/18216747/sprint-sues-att-5g-evolution-e-lies-misleading|title=Sprint is suing AT&T over '5G E' lies|last=Porter|first=Jon|date=2019-02-08|website=The Verge|access-date=2019-02-08}} However, the two parties later settled, with AT&T being allowed to continue to promote their network with the trademark.{{Cite web|url=https://www.theverge.com/2019/4/22/18511660/att-sprint-5ge-false-advertising-lawsuit-settlement|title=Sprint and AT&T settle lawsuit over "blatantly misleading" 5G E logo|last=Robertson|first=Adi|date=2019-04-22|website=The Verge|access-date=2019-04-23}}

In May 2020, following complaints by T-Mobile to the National Advertising Division, the National Advertising Review Board (NARB) recommended that AT&T stop using "5G Evolution" or "The First Step to 5G" in advertising, as "the term 'Evolution' is not likely to alert consumers to the fact that the service is not 5G." AT&T stated that it would not use "5G Evolution" or the slogan in future advertising, but that it will still use the 5G E logo, and not remove the indicator from devices.

Cingular Wireless began its sponsorship of the #31 Chevrolet, owned by Richard Childress Racing, in the NASCAR Winston Cup Series in 2002. Two years later, when Nextel Communications (now Sprint Corporation) purchased the naming rights to NASCAR's top division (rebranding the division as the Nextel Cup, and later the Sprint Cup), Cingular and Alltel, sponsor of the #12 Dodge (owned by Penske Racing and driven by Ryan Newman), were allowed to stay as sponsors under a grandfather clause. In early 2007, following its purchase by AT&T, Cingular began a re-branding effort to the AT&T Mobility brand. NASCAR quickly claimed that a clause in their contract with Sprint Nextel (the Viceroy rule) would not allow Cingular to change either the name or brand advertised on the #31 car.

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, driven by Jeff Burton, in time for the Nextel All-Star Challenge that evening.{{Cite web |url=http://www.nascar.com/2007/news/headlines/cup/05/18/att.wins.lawsuit.ap/index.html |title=NASCAR.COM - Judge rules AT&T; can change branding of No. 31 - May 18, 2007 |access-date=August 26, 2007 |archive-url=https://web.archive.org/web/20070521200500/http://www.nascar.com/2007/news/headlines/cup/05/18/att.wins.lawsuit.ap/index.html |archive-date=May 21, 2007 |url-status=dead |df=mdy-all }}{{cite web|url= http://www.nascar.com/2007/news/headlines/cup/05/19/nascar.loses.stay.att.ap/index.html| title=NASCAR loses stay, AT&T; logo allowed on No. 31 car|archive-url=https://web.archive.org/web/20070521164853/http://www.nascar.com/2007/news/headlines/cup/05/19/nascar.loses.stay.att.ap/index.html| archive-date= May 21, 2007}} NASCAR was later granted an appeal to be heard on August 2.

On June 17, NASCAR announced it had filed a US$100 million lawsuit against AT&T and would like AT&T and all other rival telecommunications companies out of the sport in 2008.{{cite web|title=NASCAR sues AT&T; for $100 million in countersuit|url=http://www.nascar.com/2007/news/headlines/cup/06/17/nascar.sues.att.ap/index.html|access-date=13 November 2017|archive-url=https://web.archive.org/web/20070617225706/http://www.nascar.com/2007/news/headlines/cup/06/17/nascar.sues.att.ap/index.html|archive-date=June 17, 2007}}

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 from featuring its logo on the car. The 11th Circuit dismissed a lower court's ruling that prevented NASCAR from stopping AT&T's plans. The appeals court remanded the case to the district court.{{cite web|title=Appeals court sides with NASCAR in AT&T; dispute|url=http://www.nascar.com/2007/news/headlines/cup/08/13/jburton.nascar.lawsuit/index.html|website=nascar.com|access-date=14 November 2017|archive-url=https://web.archive.org/web/20070816092205/http://www.nascar.com/2007/news/headlines/cup/08/13/jburton.nascar.lawsuit/index.html|archive-date=August 16, 2007|date=August 13, 2007}}

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, associate sponsors appeared, but no primary sponsors were on the car, similar to Formula One cars run in races where tobacco advertising is 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.[https://www.espn.com/racing/news/story?seriesId=2&id=2989526 As the logo turns: Burton's car missing AT&T again] ESPN. 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.{{cite web|title=NASCAR rejects proposed paint schemes for No. 31|url=http://www.scenedaily.com/stories/2007/08/20/scene_daily452.html|access-date=13 November 2017|archive-url=https://web.archive.org/web/20070825154848/http://www.scenedaily.com/stories/2007/08/20/scene_daily452.html|archive-date=August 25, 2007|date=August 23, 2007}} NASCAR later denied these claims.[https://www.espn.com/racing/news/story?seriesId=2&id=2990201 NASCAR losing patience with AT&T court battle] ESPN.

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 Chevrolet was not affected, because it is in a lower series.{{cite news|last1=Fryer|first1=Jenna|title=AT&T, NASCAR Reach Sponsorship Agreement|url=https://www.washingtonpost.com/wp-dyn/content/article/2007/09/07/AR2007090701537.html|access-date=13 November 2017|agency=The Associated Press|newspaper=The Washington Post|date=September 7, 2007}}

No division of AT&T have sponsored any organization in NASCAR since, even though the Viceroy rule changed from telecommunications companies to beverages when Monster Energy took over sponsorship of the Cup Series in 2017 before NASCAR removed series title sponsorship in the Cup Series altogether, effectively removing any restrictions on which brands can sponsor teams, pursuant to NASCAR approval. In fact, AT&T's parent division had sued a NASCAR team and driver it sponsored, Mike Borkowski, on performance grounds.[https://web.archive.org/web/20020904204429/http://sportsillustrated.cnn.com/motorsports/news/2000/11/07/borkowski_suit_ap/ Sponsor fights back], CNNSI, November 7, 2000, Retrieved 2012-07-11

In 2012, AT&T came under scrutiny for throttling the speed of data delivered to consumers with an unlimited data plan. The company has claimed that, despite its claim of network speeds, it is within its legal rights to reduce the speed of data to consumers who reach preset thresholds. In May 2012, Matt Spaccarelli, a truck driver, won a small claims lawsuit against the company for slowing down his service. A Simi Valley, California judge awarded Spaccarelli $850, agreeing that "unlimited" service shouldn't be subject to slowdowns.{{cite news| url=http://www.huffingtonpost.com/2012/03/01/att-data-throttling-unlimited_n_1314046.html | work=Huffington Post | title=AT&T Comes Clean On Throttling 'Unlimited' Data | date=March 1, 2012}} Additionally, AT&T's user agreement does not permit class-action suits against the company.Reardon, Marguerite.

In May 2013, AT&T added a 61 cent "Mobility Administrative Fee" per-month per-line to all of its wireless postpaid lines, including lines still under service contract. The fee appears "below the line" making it appear like a tax at the bottom of a customer's phone bill. This fee is thought to bring more than a half-billion dollars in a year for AT&T, which claims the fee is for covering the cost of cell sites and maintenance.{{Cite web|url=https://www.cnet.com/news/at-t-adds-61-cent-mobility-fee-to-wireless-bills/|title=AT&T adds 61-cent 'mobility' fee to wireless bills|last=Mihalcik|first=Carrie|website=CNET|language=en|access-date=2019-02-05}} In June 2018, AT&T raised the administrative fee to $1.99 from 76 cents per-line.{{cite web |last1=Villas-Boas |first1=Antonio |title=AT&T is adding $1.23 to your wireless bill, which could make it an extra $800 million this year |url=http://www.businessinsider.com/att-increases-admin-fee-on-wireless-bills-will-make-800-million-more-year-2018-6?r=UK&IR=T |website=Business Insider |access-date=13 July 2018}}
