(NASDAQ: PHCM), and Telstra Corporation Limited, Australia's largest telecommunications company, today announced at the Unwired Universe Conference that Telstra Corporation has licensed the Phone.com� Wireless Application Protocol (WAP)-compatible UP.Link� Server. Under the terms of the agreement, Telstra will use its Phone.com software license to provide new wireless Internet service offerings to its Australian mobile customers.

Phone.com's software will enable Telstra to offer mobile customers with WAP-capable mobile phones access to a full range of Telstra information services and resources.

These new Telstra services can be accessed through mobile phones equipped with a WAP-compatible microbrowser such as the Phone.com� UP.Browser� microbrowser.

"In the future, we expect WAP will provide not only interaction with Internet based information, such as transport timetables, flight arrival and departures, and telephone directory information services, but users will be able to check bank accounts and carry out transactions as well as gain access to on-line ticketing with airlines."

"Our agreement with Telstra shows that Phone.com continues to deliver on our strategy to provide world class telecommunications companies the fastest time to market for scalable and reliable WAP services." said Alain Rossmann, president and chief executive officer of Phone.com.
