MCI ANNOUNCES WIRELESS AND INTERNATIONAL ACCESS OPTIONS FOR MCI MAIL.

ATLANTA--(BUSINESS WIRE)--Aug. 28, 1996--MCI announced today two new access options for its MCI Mail customers -- a new wireless access to MCI Mail using XstreamAir and increased international access via Concert Packet Services.

Effective immediately, MCI Mail users can now send and receive e-mail messages even without a phone line with MCI's new wireless access service for MCI Mail. Using a cellular phone connected to a personal computer, customers simply dial an MCI XstreamAir access number and connect to MCI Mail and all of it's delivery options. The wireless access option is available nationwide where there is cellular service.

XstreamAir is a dial up data network service that supports reliable circuit switched cellular data calls to host data applications such as MCI Mail. By accessing XstreamAir, which supports data correction protocols MNP10 and ETC, customers are assured of quality connections and high speed performance. While there is no charge for using the local XstreamAir access number, an 800 number for XstreamAir is available at $.10/minute.

"MCI Mail's wireless access option is ideal for traveling executives and roaming field personnel such as technicians and sales representatives," said Martha Hanlon, MCI's director of messaging marketing. "By utilizing XstreamAir access, the customer is assured of receiving high quality connections. Because the technology is in our network, and not the cellular network, customers can make wireless data calls anywhere they can make a voice call today."

MCI ADDS LOWER COST INTERNATIONAL ACCESS TO MCI MAIL

MCI also announced, effective September 1, increased international accessibility of MCI Mail to 48 countries via the global Concert Packet Services(a) network -- a global data packet network operated by Concert, the BT-MCI joint venture for global services. The rate for using the service is $.35/minute, except in Canada where the rate will be $.06/minute.

MCI Mail Global Access (MMGA)(b) continues to be an alternative access method outside the U.S., and is available in 32 countries at a rate of $.50/minute, with Datapac (a Canadian data packet network) access available in Canada for $.15/minute. In some countries, both MMGA and Concert Packet Services access will be offered giving customers a choice in access options. Without Concert Packet Services or MCI Mail Global Access, customers would need to make prior arrangements with the local telecommunications provider or place a long distance call to the United States.

MCI, headquartered in Washington, D.C., is one of the world's largest and fastest growing diversified communications companies. With annual revenue of more than $15 billion, MCI offers consumers and businesses a broad portfolio of services including long distance, wireless, local, paging, messaging, Internet, information services, outsourcing, and advanced global communications.
