SEVEN-Enabled Email Services Now Available to 80% of Japanese Mobile Subscribers -- The World's Largest Mobile Data Market

Redwood City, Calif. (October 6, 2003) - SEVEN, a leader in Out of Office™ mobile technologies, announced today that SEVEN-enabled services are now available to 80% of Japanese mobile subscribers. SEVEN is the only mobile email provider to penetrate the Japanese market, providing secure, real-time mobile email services to businesses and individual users. SEVEN services are available via NTTDoCoMo and KDDI Corp.

Named 2003 Network Magazine Mobile Service of the Year, SEVEN services have been internationalized and localized for operators worldwide, and deployed in leading wireless data regions including Japan, Asia Pacific, Europe and North America. SEVEN is the only mobile data services company to serve as the foundation for tier-one business services at Japan's two leading operators.

"The success of SEVEN's Japanese deployments is driven by the success we've seen from North American and European operators adopting our network-centric approach," said Bill Nguyen, founder and president of SEVEN. "Japanese operators have experienced unprecedented subscriber adoption and generated increased revenue in the consumer market. By launching SEVEN-enabled services, they are looking to extend their consumer traction to the enterprise market."

Japan's mobile phone market is growing exponentially; according to the Japan Electronics and Information Technology Industries Association (JEITA), the monthly shipment of mobile devices has exceeded 4 million for the past four consecutive months. Furthermore, Japan's 75 million subscribers are among the world's most prolific data users enjoying fully deployed next-generation networks and devices. The average data revenue per subscriber in Japan is $12, which is higher than any other region.

"Japan has historically driven much of the mobile data innovation in the prosumer market," said Stephen Drake, Mobile Infrastructure Software Program Manager, at IDC, a leading provider of global IT research and advice. "The ability to penetrate this key regional market is critical to market leadership."

In addition to SEVEN's leading position in Japan, SEVEN also delivers the greatest flexibility for individuals and businesses considering a mobile groupware service.
