BellSouth Mobility DCS was a mobile phone network operated by the American landline telephone company BellSouth. It was founded in the mid-nineties. It ran GSM at 1900 MHz, and covered North and South Carolina, and eastern parts of Georgia and Tennessee. In 2000, it became part of the Cingular Wireless network, and the BellSouth branding was dropped. It then legally existed as BellSouth Mobility DCS, Inc. d/b/a Cingular Wireless. In 2007, it became known as BellSouth Mobility DCS, Inc. d/b/a AT&T Mobility.
