AT&T GoPhone is the brand name of prepaid mobile phone service from AT&T Mobility, a wholly owned subsidiary of AT&T Inc. 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. 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.
