AT&T Mobility

AT&T Mobility, LLC, also known as AT&T Wireless and <a href="/facts/Trade_name/0tbWP1Sn">marketed</a> as simply AT&T, is an American telecommunications company. Formed in April 2000 as Cingular Wireless LLC, It is a <a href="/facts/Wholly_owned_subsidiary/l25YN38x">wholly owned subsidiary</a> of <a href="/facts/AT%2526T/y3Lo9uhk">AT&T Inc.</a> and provides <a href="/facts/Wireless/GfDoFwfo">wireless services</a> in the <a href="/facts/United_States/P0sCdLe5">United States</a>. AT&T Mobility is the <a href="/facts/List_of_mobile_network_operators_in_the_United_States/lbpULz7Q">third largest wireless carrier in the United States</a>, with 118 million subscribers as of March 31, 2025.
The company is headquartered in <a href="/facts/Brookhaven%2c_Georgia/NTAdDw1X">Brookhaven, Georgia</a>. Originally known as Cingular Wireless (a joint venture between <a href="/facts/SBC_Communications/hjL9lrHX">SBC Communications</a> and <a href="/facts/BellSouth/vT90BWJj">BellSouth</a>) from 2000 to 2007, the company acquired the old <a href="/facts/AT%2526T_Wireless_Services/6lVrmR3n">AT&T Wireless</a> in 2004; SBC later acquired <a href="/facts/AT%2526T_Corporation/BfsX7eX2">the original AT&T</a> and adopted its name. Cingular became wholly owned by AT&T in December 2006 as a result of AT&T's <a href="/facts/Mergers_and_acquisitions/YfczSf3M">acquisition</a> of BellSouth.
In January 2007, Cingular confirmed it would rebrand 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 <a href="/facts/Apple_Inc./oTJYta3k">Apple</a> <a href="/facts/IPhone/h5WeKRl9">iPhone</a>.
On March 20, 2011, AT&T Mobility announced its intention to acquire <a href="/facts/T-Mobile_US/tRY9PLtF">T-Mobile US</a> from <a href="/facts/Deutsche_Telekom/GBfL2DPH">Deutsche Telekom</a> for $39 billion. If it had received government and regulatory approval, AT&T would have had more than 130 million subscribers. However, the <a href="/facts/U.S._Department_of_Justice/2SuTuevo">U.S. Department of Justice</a>, the <a href="/facts/Federal_Communications_Commission/Ueghz8W0">Federal Communications Commission</a> (FCC), and AT&T Mobility's competitors (such as <a href="/facts/Sprint_Corporation/lD1pWBWS">Sprint Corporation</a>) opposed the move on the grounds that it would substantially reduce competition in the <a href="/facts/Cellular_network/8zA0jQJ9">cellular network</a> market. In December 2011, in the face of both governmental and widespread consumer opposition, AT&T withdrew its offer to complete the merger.
