AT&T Wireless and T-Mobile USA Sign Airport Wi-Fi Roaming Agreement

February 04, 2004

Agreement Covers Wi-Fi at Denver International, Philadelphia International and San Francisco International Airports

Bellevue, Wash. — Feb. 5, 2004

Driving expanded Wi-Fi (802.11b) service coverage at the nation's airports, T-Mobile USA, Inc. and AT&T Wireless (NYSE: AWE) today announced a reciprocal Wi-Fi roaming agreement for Denver International (DIA), Philadelphia International (PHL) and San Francisco International (SFO) airports. Today’s announcement marks the first roaming agreement between AT&T Wireless and T-Mobile for Wi-Fi service.

As a result of this roaming agreement, T-Mobile HotSpot subscribers can soon add DIA and PHL to the list of hotspot locations available to them to stay connected to the Internet, access their corporate networks, or check e-mail via a Wi-Fi enabled laptop or PDA. For AT&T Wireless Wi-Fi customers, the roaming agreement means they will be able to use their Wi-Fi device throughout the public areas of SFO. The companies’ respective customers will be able to roam using their same user ID and password.

"Whether using Wi-Fi in a local hotspot or our EDGE service throughout thousands of cities, AT&T Wireless customers can stay connected to their critical, corporate information while away from the office,” said Jeff Bradley, senior vice president for business data offers at AT&T Wireless. "The addition of SFO is an important component in our airport Wi-Fi strategy, and it will be the seventh major airport in which our customers will have access to a Wi-Fi network.”

“We’re pleased to offer our T-Mobile HotSpot subscribers the added value this roaming agreement brings,” said Joe Sims, vice president and general manager of T-Mobile HotSpot. “In addition to more than 4,000 convenient locations our subscribers can visit today, they will soon have even more airports where they can stay connected to important information during a layover or waiting for their flight.”

The parties expect to complete integration efforts and enable roaming in mid-2004. For rates and technical support to connect to either the AT&T Wireless or the T-Mobile HotSpot Wi-Fi service, please visit their respective Web sites at www.attwireless.com/wifi and www.t-mobile.com/hotspot.
