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 billion.
Cingular became wholly owned by AT&T in December 2006 as a result of AT&T's acquisition of Bell South.
Originally known as Cingular Wireless from 2000 to 2007, a joint venture between SBC Communications and Bell South, the company acquired the old AT&T Wireless in 2004; SBC later acquired the original AT&T.
Existing customers who had A-List on their account prior to September 1, 2011, are able to keep the feature as long as they stay on a qualifying rate plan.
As of October 25, 2013 AT&T no longer offers Nation Plans or Family Talk Plans to its new customers.
The CWA represented roughly 15,000 of the previous 20,000 formerly AT&T Wireless employees as of early 2006.
