AT&T Mobility LLC or AT&T U.S. Mobility, also known as AT&T Wireless, marketed as simply AT&T, is a wholly owned subsidiary of AT&T Inc. that provides wireless services to 165.9 million subscribers in the United States, including Puerto Rico and the U.S. Virgin Islands. AT&T Mobility is the largest wireless telecommunications provider in the United States and Puerto Rico ahead of Verizon Wireless and the largest wireless telecommunications provider in North America when including AT&T Mexico.\nOriginally known as Cingular Wireless (a joint venture between SBC Communications and BellSouth) from 2000 to 2007, the company acquired the old AT&T Wireless in 2004; SBC later acquired the original AT&T and adopted its name. Cingular became wholly owned by AT&T in December 2006 as a result of AT&T's acquisition of BellSouth.\nIn 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.\nOn March 20, 2011, AT&T Mobility announced its intention to acquire T-Mobile USA from Deutsche Telekom for $39 billion. If it had received government and regulatory approval, AT&T would have had more than 130 million subscribers. However, the U.S. Department of Justice, the Federal Communications Commission (FCC), and AT&T Mobility's competitors (such as Sprint Corporation) opposed the move on the grounds that it would substantially reduce competition in the cellular network market. In December 2011, in the face of both governmental and widespread consumer opposition, AT&T withdrew its offer to complete the merger.
