Cingular Wireless and MetroPCS enter into agreement on sale of wireless spectrum to MetroPCS in Dallas and Detroit markets

FOR RELEASE MONDAY, NOVEMBER 29, 2004

ATLANTA and DALLAS — Cingular Wireless, a joint venture between SBC Communications Inc. (NYSE: SBC) and BellSouth Corp. (NYSE: BLS), and MetroPCS, Inc. today announced they have entered into a definitive agreement on the sale of wireless spectrum to MetroPCS.

Under the terms of the agreement, Cingular has agreed to sell to MetroPCS licenses for ten megahertz of wireless spectrum in Dallas and ten megahertz in Detroit for $230 million in cash.

Through this transaction, Cingular continues to fulfill the divestiture obligations imposed by the Department of Justice and Federal Communications Commission as conditions of their approval of Cingular’s merger with AT&T Wireless.

“We are very excited to be able to obtain this spectrum, which will allow us to develop two more of the largest markets in the United States with our unique service,” said Roger Linquist, Chairman, CEO, and President of MetroPCS. “Added to the large markets we already serve – Atlanta, Miami, and San Francisco – MetroPCS will now be a force in five of the top twelve U.S. metropolitan areas.”

Closing of the transaction agreement is contingent upon regulatory approval and is expected to occur in the first quarter of 2005.

Bear, Stearns & Co. Inc. acted as financial advisor to MetroPCS and provided a commitment of bridge financing for the license acquisitions.
