DULLES, Va. & REDMOND, Wash.--(BUSINESS WIRE)--Jan. 31, 2002

America Online, Inc. (NYSE:AOL), the world's leading interactive services company, and AT&T Wireless (NYSE:AWE), the largest independently traded wireless carrier in the United States, announced that the AOL(R) Instant Messenger(TM) (AIM) service is now available on select AT&T Wireless phones.

The AIM service is used by millions of Internet users every day to communicate in real-time with friends and family. Instant messaging has become an online phenomenon, and now, AT&T Wireless customers can access their AOL Buddy List(R) and "chat" with family and friends by typing short text messages on their wireless phones. Customers also have the added benefit of knowing that their messages are being received and read virtually in real-time.

"Together, AOL and AT&T Wireless have tens of millions of customers who want simple ways to stay connected with the people they care about," said John Bunyan, senior vice president of AT&T Wireless Mobile Multimedia Services. "Now our customers can use AOL's popular instant messaging service with the added freedom of being able to step away from their desktop whenever they want to do so. Messaging services, including instant messaging, text messaging, and e-mail, will become a defining consumer wireless data application in 2002. As we continue to expand our messaging portfolio, we're proud to have a leader like AOL by our side."

"AOL is excited to bring this service to AT&T Wireless subscribers, as more and more people around the world are embracing the tremendous convenience of instant messaging from mobile devices," said Lisa Hook, president of AOL Anywhere. "Using the AIM service on wireless phones really unites the wired and wireless worlds, offering an easy and fun way for people to stay connected with family, friends and co-workers, whether they're online from their computer or on their phone. It's another example of how we continue to build and deliver the best interactive communication experience to consumers, no matter where they are."

Millions of people have made instant messaging part of their daily lives, and many others are learning how simple, fun and convenient it can be. Already, AOL's online audiences send more than 1.3 billion instant messages a day to their friends and loved ones. With "mobile" instant messaging, they have that convenience wherever they go and enjoy benefits such as:

-- Chat Without Talking - Mobile instant messaging is ideal in situations when
you need to reach someone quickly and discreetly;

-- See When Contacts Are Available - With AOL's Buddy List feature, you have
the added benefit of seeing whether the person you're trying to reach is
actually connected and available to communicate;

-- Stay in Touch - Everyone from busy professionals to teenagers and college
students are placing a greater emphasis on staying in touch with their friends
and family -- mobile instant messaging offers a convenient way for the millions
of consumers using cell phones or other handheld mobile devices exchange quick
messages in real-time.

Customers will not have to pay any additional fees to use the AIM service beyond those of AT&T Wireless' standard text messaging feature plans:

-- Pay no monthly charge and pay $.10 per message sent OR

-- Pay 4.99 per month for 100 included outgoing messages and $.10

per message thereafter.

Both plans offer customers unlimited incoming instant messages for no additional charge.

Availability: The AIM service for AT&T Wireless subscribers nationwide is now available on all 2-way text messaging capable phones. A complete list of AT&T Wireless 2-Way Text Messaging capable phones is available at www.attwireless.com. To set-up and register their existing mobile phones with the AIM service, customers can visit www.attwireless.com/aim or AOL Keyword: Wireless.

The AIM service is available through major wireless network carriers and is an extension of the AOL Anywhere(SM) strategy to make AOL's industry-leading brands and features available to online consumers anywhere, anytime through a range of devices beyond the PC. This launch builds upon the cooperative efforts that America Online and AT&T Wireless have announced, including the introduction of the AOL(R) Mobile service for AT&T Wireless PocketNet(R) subscribers -- providing access to e-mail, movie show times, weather updates, shopping capabilities and more. The two companies will continue to work together on cross-promotional opportunities to enrich the wireless experience of their collective customers. This launch also builds on AT&T Wireless' pioneering legacy in messaging services. AT&T Wireless was the first national carrier to bring short messaging service (SMS) to the United States. Last November, AT&T Wireless also became the first national carrier to allow its customers to send text messages to virtually any wireless phone -- regardless of the carrier -- simply by knowing the recipient's phone number.
