Openwave And Verisign Team To Drive Advanced Mobile Messaging Community



VeriSign To Provide Service Bureau for Openwave Mobile Instant Messaging

Openwave Systems Inc. (Nasdaq: OPWV), the worldwide leader of open IP-based communication infrastructure software and applications, and VeriSign Inc. (Nasdaq: VRSN), the leading provider of digital trust services, today announced that they will collaborate to drive adoption of advanced mobile messaging services. The collaboration calls for VeriSign to host Openwave's SMS-enabled Mobile Instant Messaging solution for carriers as a service bureau offering. Additionally, VeriSign and Openwave will work together to provide their mutual customers with a tightly integrated solution for inter-carrier messaging (ICM). This solution includes the Openwave(tm) Mobile Messaging Gateway (MMG) in the carrier network as the gateway to the VeriSign Metcalf Global Messaging (Metcalf GM) ICM service that VeriSign has deployed with MobileSpring, for delivery of SMS messages outside of the originating carrier network.

Openwave and VeriSign expect these messaging solutions to be compelling and popular with carriers and their users worldwide.

Benefits include:
Carrier Benefits
* Accelerate SMS and Mobile Instant Messaging adoption and usage in the Americas. As seen in Europe, inter-carrier messaging communities have proven to be the critical catalysts of highly profitable mobile messaging services.
* Provide operators with a service bureau implementation of their own branded, highly scalable and interoperable Mobile Instant Messaging service, along with a low-risk, pay-as-you-grow model from a proven leader in service
bureau offerings for operators.
* Provide a proven end-to-end solution to intelligently route, consolidate, track and deliver a growing volume of SMS messages over the more cost-effective IP network, both within and between different operator networks.

User Benefits
* Make it possible to address short text messages to other users by simply using their mobile phone numbers or their buddy names, ignoring previous barriers between different operators.
* Enhance the SMS experience by adding instant messaging features like presence-enabled buddy lists that provide users with information on the availability of their online "buddies."
* Provide for the upgraded experience of full instant messaging through WAP, native mobile client and PC interfaces, in addition to SMS.

"There are currently around 30 billion SMS text messages and 30 billion Internet instant messages sent monthly. Today's announcement helps to bridge the gap between these two huge and important communities: SMS and the Internet," said Andrew MacFarlane, vice president, messaging, Openwave Systems Inc. "VeriSign's scalability and secure service capabilities and Openwave's advanced messaging portfolio will provide carriers with the right
combination of technology to deliver open, flexible mobile communications services to both consumer and business users."

"While businesses and consumers already recognize the productivity benefits of SMS and instant messaging, we have only scratched the surface in adoption of these services," said Terry Kremian, executive vice president-telecommunications, VeriSign. "With Openwave's best-in-class Mobile Instant Messaging software and our experience in providing world-class services to some of the world's largest mobile operators, we can offer a tremendous opportunity for operators to grow their data services revenue with little or no capital investment. Operator-branded messaging services are critical in reducing churn and increasing subscriber stickiness."

The end-to-end SMS solution provided by Openwave and VeriSign supports interconnection between Openwave's MMG and VeriSign's Metcalf GM inter-carrier messaging service, based on application technology from VeriSign's partner, MobileSpring, a leader in wireless messaging. Openwave and VeriSign intend to cooperate to ensure that the MMG and the Metcalf GM service are optimized for one another in a way that allows for support of advanced end-to-end user features, including confirmed delivery, validity periods and urgency indicators.
