Diversinet Launches Passport SMS Messenger Zero-Client Solution For Existing Phones

Enterprise solution uses existing mobile phones to help Internet-enabled applications easily reach users

TORONTO, Canada, May 7, 2003 – Diversinet Corp. (Nasdaq OTCBB: DVNT), a leading provider of secured mobile solutions, today announced the launch of Passport SMS Messenger, a new zero-client solution that enables application providers and enterprises to rapidly extend mobile connectivity to key business and consumer applications.

Passport SMS Messenger provides a complete, cost-effective solution for mobilizing Internet-aware applications by using current mobile phones and widely-available text messaging services.

It is a server-side solution that supports industry-standard messaging and communication protocols. This model provides organizations with a key tool that can help in unlocking the promise of mobility for such applications as mobile lotteries and sweepstakes, and authenticating credit card purchases made via the Internet.

“By employing Passport SMS Messenger, enterprises and customer-facing organizations can quickly deploy mobile-enabled features, and extend their return on a broad range of applications,” said Hussam Mahgoub, Vice President of Products at Diversinet Corp. “With more than 1 billion SMS messages exchanged each month, this solution incorporates a service platform that people worldwide already have and use.”

Passport SMS Messenger brings mobility to the Internet world while removing the need to develop applications that use specific mobile communication protocols. Passport SMS Messenger is a zero-client solution that works with existing mobile phones, and can address mass-market Internet applications. Passport SMS Messenger can be deployed quickly and easily with most Internet-aware applications since it manages the exchange of information between an application and the mobile service provider’s messaging gateway. The application interface supports industry-standard messaging and communication formats. Passport SMS Messenger supports XML, HTTP and SMPP, and will soon support UCP and other commonly-used protocols.

It is an ideal solution for enterprises that want to extend corporate applications to mobile devices using commonly-available SMS technology. Enterprises are looking for ways to extend existing applications to mobile workers, and mobility presents new access channels to application providers who make value-added services available to both consumer and business users.

“Mobile wagering has the promise of being an enormous channel for gaming operators as it allows them to reach users anytime, anywhere,” said Dr. Lee Keng Ho, Chief Executive Officer, Effective Solution Ltd. “Diversinet’s Passport SMS Messenger allows lottery service providers to deliver lotteries to the majority of wireless users by leveraging commonly available SMS services and existing mobile phones.”
