AT&T Mobility
former wireless service subsidiary of AT&T
AT&T Mobility, LLC, also known as AT&T Wireless and marketed as simply AT&T, is an American telecommunications company. Formed on October 5, 2000 as Cingular Wireless LLC, it is a wholly owned subsidiary of AT&T Inc. and provides wireless services in the United States. AT&T Mobility is the third largest wireless carrier in the United States, with 109.8 million subscribers as of June 30, 2026.
The company is headquartered in Brookhaven, Georgia. Originally 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.
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 Apple iPhone.
This brief starts where responsible research should: with the source description of “AT&T Mobility” as former wireless service subsidiary of AT&T. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as former wireless service subsidiary of AT&T. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 4, 2026. The linked authority identifier is Q298594. VIAF identifies the subject as 154923041. The Library of Congress control number is n94018570. 3 of 5 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 2000, 2026, 2007 and 2004.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
