AT&T Introduces Two New Services That Make Nationwide Paging Reliable and More Affordable.

KIRKLAND, Wash.--(BUSINESS WIRE)--Aug. 17, 1998--AT&T Wireless Services Messaging Division announced today two new services that provide customers increased reliability and flexibility in nationwide paging options.

The first, called AT&T AlphaTrack(SM) Service, helps ensure the delivery of pages by storing messages when the user is out of their coverage area and automatically delivering them when they return to full coverage. The second, called AT&T PreferredCity(SM) Service, allows people to access nationwide paging coverage at lower prices.

AT&T ALPHATRACK(SM) SERVICE

This enhanced paging service stores messages when the pager is out of its coverage area, then automatically delivers them when the customer returns to a full coverage area. For instance, if the customer is on a plane, AT&T AlphaTrack Service will store messages until the customer lands and then deliver the messages to the pager. Pages are automatically re-sent to the user's pager when they return toa full coverage area within 72 hours. And for those times when a customer can't return to a full coverage area, AT&T AlphaTrack lets the customer call in and listen to messages. This service will even correct and re-send garbled messages.

AT&T AlphaTrack also provides features such as Page Recall and Message Retransmission. The system stores messages up to four days (99 hours) and allows a caller to listen to those messages over the phone, or retransmit them to their pager.

With AT&T AlphaTrack Service, customers will worry less about missing a page, because now the page will be delivered when the customer returns to a coverage area.

AT&T PREFERREDCITY(SM) SERVICE

AT&T PreferredCity Service was designed as a low-cost nationwide paging service alternative. This special type of nationwide paging service lets the customer specify where pages are sent. When traveling to a city outside the local coverage area, a single call is all it takes to redirect pages. The caller simply specifies the city in which they want to receive pages by making a phone call and entering the local area code. And, if the customer is between cities, he or she can have the most recent messages re-sent to their pager when they return to a coverage area. Numeric pages can be repeated over the phone.

AT&T PreferredCity Service is one of the most affordable nationwide paging services available, yet it includes more alphanumeric messages, and longer messages than AT&T's full time nationwide service. It is the perfect service for people who travel occasionally, but need to stay in touch with business and family.

FAST, EFFICIENT COVERAGE, COAST TO COAST

Both of these new services from AT&T Wireless Services provide coast-to-coast coverage throughout the continental United States(a). In addition, AT&T PreferredCity Service provides coverage in Alaska, Hawaii, Puerto Rico, the Bahamas and the U.S. Virgin Islands. Both services utilize a single pager with a single pager number when at home or traveling. And, AT&T Wireless Services offers multiple dispatch options for callers, including Internet Messaging options. Anyone with Internet e-mail can send messages to an AT&T AlphaTrack or AT&T PreferredCity alphanumeric pager(b).

ADDITIONAL FEATURES AVAILABLE

AT&T AlphaTrack Service and AT&T PreferredCity Service offer optional features for an additional charge. Included in these options are Personal Toll-free Numbers, VoiceMail, and Live Operator Dispatch--a service that lets a person send a text message through an operator who transcribes and sends the message. AT&T also offers MessageFlash(R) Text Messaging Software, an easy-to-use software program that lets people send detailed text pages directly from their computer. It's the perfect solution for computers without Internet access.

AT&T Wireless Services is the largest full service wireless carrier in the United States with more than 8.75 million wireless customers. AT&T Wireless Services also offers wireless data and aviation communications services. AT&T Wireless Services, Inc. is a wholly owned subsidiary of AT&T Corp. (NYSE:T). AT&T has signed a definitive sale agreement with Metrocall Inc. (Nasdaq:MCLL) for Metrocall to acquire the Advanced Messaging Division of AT&T Wireless Services. Closure of the sale is targeted for fourth quarter, 1998.

(a) Because pagers use radio signals, you may not be able to receive messages in certain areas, such as tunnels and buildings, and under some atmospheric conditions.

(b) Service is available to alphanumeric paging customers on AT&T's owned and operated network and on AT&T Nationwide, AT&T AlphaTrack, and AT&T PreferredCity Services.
