AT&T Extends Global Network to Vietnam

AT&T Announces Collaboration with Viettel to Extend Networking Services to Multinational Companies in Vietnam

San Antonio, Texas, November 15, 2006

Hanoi, Vietnam - AT&T Inc. (NYSE: T) today announced that Vietnam will be accessible from the AT&T global network through collaboration with one of the leading local telecommunication carriers, Viettel Corporation. The collaboration with Viettel, sealed against the backdrop of the Asia Pacific Economic Cooperation CEO Summit 2006 (APEC CEO Summit) in Hanoi, paves the way for AT&T to extend advanced information and communications support to its growing number of multinational enterprises customers with sites in Vietnam.

Chris Rooney, senior vice president of AT&T Operations Inc., who will also speak at the APEC CEO Summit 2006, said, "As the second fastest-growing economy in the Asia Pacific region, Vietnam is an exciting place for us to be deepening our network reach. AT&T can already provide data services to a global area accounting for 97 percent of the world's economy, and our collaboration with Viettel will extend it further. This demonstrates our commitment to global customers who are doing business in Vietnam and our determination to provide them with a consistent set of services offering high levels of quality and reliability wherever they do business."

"Global enterprises require transnational communications support in order to function efficiently, and their decisions are influenced by the availability of a reliable communications infrastructure before they move into new markets. We expect that this collaboration between AT&T and Viettel will promote investment in Vietnam by all telecom-dependent industry sectors and provide a catalyst for further economic growth in the country," Mr. Rooney added.

AT&T currently serves customers with sites in Vietnam through interconnection agreements with domestic telecom carriers. Viettel will provide services within Vietnam, while AT&T will provide service outside Vietnam. However, through this collaboration, Viettel and AT&T will connect Vietnam into the AT&T Global network and offer multinational enterprise customers in the country advanced networking services through Viettel. Initial services will include Virtual Private Network and Frame Relay services. There are plans to add more services in the future.

Following the recent award of new telecom licenses to AT&T in India announced in October, the collaboration agreement in Vietnam marks another significant milestone for AT&T in the expansion of its global network, providing enhanced connectivity in the United States and around the world to meet the growing demands of multinational enterprises. Today, AT&T offers MPLS-based services in 137 countries from more than 1,600 service nodes. AT&T also offers remote access in 149 countries through 45,000-plus access points.
