BellSouth Mobility, LLC headquartered in Atlanta, Georgia, was a BellSouth subsidiary.

BellSouth Mobility operated wireless networks using many different wireless communication standards. The most widely used of these technologies is called Digital AMPS, or D-AMPS. Data services were provided by BellSouth Wireless Data, and used the pre-2.5G Mobitex standard[1].

BellSouth Mobility was a mobile phone network operated by the American landline telephone company BellSouth. It was founded in 1984 during the breakup of AT&T, which included dividing Advanced Mobile Phone Service, Inc. among the Baby Bells. It ran AMPS and D-AMPS across most of the territory covered by the BellSouth landline company. In 2000, it became part of the Cingular Wireless network, and the BellSouth branding was dropped.

As now part of AT&T Mobility, BSM is known as BellSouth Mobility, LLC d/b/a Cingular Wireless.


  • BellSouth Mobility used D-AMPS as opposed to Sprint and Verizon's IS-95 technology. Despite this, BellSouth Mobility offered Sprint and Verizon customers roaming on to their older AMPS network.
