AT&T Wireless Forms Systems Integrator Program to Design and Implement End-to-end Mobile Solutions for U.S. Corporations

Initial Members Include Cap Gemini Ernst & Young, Deloitte Consulting, Fujitsu Consulting and HP

New Orleans, LA, March 18, 2003 — AT&T Wireless (NYSE: AWE - News) today announced the formation of the AT&T Wireless' Systems Integrator Program with a number of leading systems integrators, including Cap Gemini Ernst & Young*, Deloitte Consulting, Fujitsu Consulting, and HP. By teaming with some of the world's leading systems integrators, AT&T Wireless is extending its ability to assist U.S. companies in the design and implementation of wireless data solutions.

In response to the growing demand of corporations to access critical business information in mobile environments, AT&T Wireless and its program members will market a broad portfolio of differentiated, repeatable, and scalable solutions for today's companies. In addition, since AT&T Wireless operates one of the largest GSM(TM)/GPRS network in the Western Hemisphere, companies will benefit from the ability to use their solutions across the U.S. and in cities throughout the world.

"Today's corporations are looking for wireless solutions that meet their unique business needs," said Carolyn Billings, senior director of business development for AT&T Wireless Mobile Multimedia Services. "By teaming with the systems integrators that these companies already rely on for IT support, we can streamline the process of delivering wireless data solutions that enhance the productivity of our corporate customers."

"We are pleased to join with AT&T Wireless, a company that mirrors our commitment to delivering superior technology solutions that enable corporations to meet their business objectives, " said Perry Spiropoulos, Vice President for Telecom Media Networks (TMN), a global industry practice of Cap Gemini Ernst & Young. "By leveraging AT&T Wireless' portfolio of products, we can offer our clients a complete mobile solution, from hardware and application, to strategy, integration and outsourcing. This alliance can enable enterprises to fully realize the benefits of a mobile workforce, enhance the productivity of the existing remote personnel and reduce operational costs."

"Data-on-the-go is ready for corporate usage, with demand growing at a rate higher than that for general technology. Shortly after first implementations, our clients have noted significant productivity gains. With this alliance, clients may objectively measure the benefits from mobility, opt for higher levels of service based on their requirements, and deploy wireless solutions faster," said David Sult, principal with Deloitte Consulting.

"At Fujitsu, we are delivering scalable enterprise mobile solutions to our customers that provide them measurable business benefits and productivity improvement. Strategic alliances with next-generation wireless providers such as AT&T Wireless complement our portfolio of solutions and allow us to provide our customers a complete end to end mobile solution," said Greg Berman, Vice President for Enterprise Mobility at Fujitsu Consulting, the global consulting arm of the $38 billion Fujitsu group.

"As more workers spend increasing amounts of time away from the office, it is critical that enterprises find ways of extending access to critical communications and information to these workers. A truly adaptive IT infrastructure has to quickly and easily adopt and deploy mobile solutions to meet this challenge," said Rene Schuster, vice president, HP Services.

"AT&T Wireless expertise in wireless communications, together with HP's leadership in IT infrastructure technology and services, is a powerful combination for our enterprise customers, who can realize immediate business benefit from end- to-end mobility solutions that are rapidly designed and deployed."

AT&T Wireless expects to add additional members to its systems integrator program throughout the year.
