AT&T Mobility

AT & T Mobility is the second -largest U.S. mobile phone company since the acquisition of AT & T Wireless by Cingular 's competitors with about 77 million customers. On 15 January 2007 the Company's name from Cingular to AT & T Wireless was converted.

Kennedy Airport, the supply of GSM 850 is better than the PCS 1900.
