Syniverse and RealNetworks Sign Long-Term Alliance

Messaging platform will support Syniverse's global SMS offerings

TAMPA, Fla., and SEATTLE – March 24, 2010 – Syniverse Technologies (NYSE:SVR) and RealNetworks®, Inc. (Nasdaq: RNWK) have entered into a nine-year alliance to use Real's intercarrier short message service (SMS) platform as the power behind Syniverse's peer-to-peer (P2P) messaging interoperability solutions. Terms of the agreement were not disclosed.

The extension of the relationship between the two companies means Real, which today provides the technology foundation underlying Syniverse's intercarrier SMS solution in the Americas, also will supply the same platform for Syniverse's global SMS Interworking Gateway, SMS Open Connectivity and SMS-IP solutions.

Charles Landry, Executive Vice President, Messaging, Syniverse, said this strategic alliance combines Syniverse's understanding of the mobile messaging ecosystem, global footprint, and network and messaging expertise with the superb development capabilities of Real.

"Subscribers around the world expect one thing from mobile messaging: That it works," Landry said. "Real, with its proven reliability, is an excellent fit with our ongoing commitment to excellence in our own platforms. Implementing their technology across all our global SMS solutions means operators everywhere will have access to the same industry-leading messaging solutions our customers have come to expect from Syniverse and will have the ability to give their subscribers a superior, consistent messaging experience anytime, anywhere."

Under the agreement, Real supplies core message processing software and services while Syniverse implements, manages and maintains the SMS interoperability offerings that include a robust set of next-generation reporting tools.

Vern Poyner, Senior Vice President, Technology Products and Solutions, RealNetworks, said he is looking forward to the opportunity to expand the benefits of Real's proven, scalable messaging platform to even more operators around the globe.

"SMS volumes are exploding worldwide as more mobile device users than ever before choose SMS as their preferred mode of mobile communication," Poyner said. "We understand, like Syniverse, that stability and reliability are essential elements of any messaging solution. With zero downtime during the past four years, the Real platform has earned an industry reputation as the premier provider of SMS technology. We are pleased to be working with Syniverse to raise the standard of mobile messaging across the world."
