Syniverse Technologies (NYSE:SVR - News), a leading provider of mission-critical technology services to wireless telecommunications companies worldwide, today announced an agreement with OpenMIND Networks to create an enhanced MMS interoperability gateway service to provide mobile operators with global interoperability.

Today, the majority of mobile subscribers can only send photos or video clips from their mobile phone to another subscriber on the same carrier network. Syniverse's MMS interoperability gateway provides the necessary interoperability to exchange MMS with subscribers on different networks, including performing the complex transcoding required between CDMA and GSM networks. Additionally, as the leading provider of mobile number portability in the United States, Syniverse's MMS gateway service provides automatic LNP database dips for all messages destined for North America.

The Syniverse MMS interoperability gateway service also leverages the global reach of the Syniverse GRX network. GRX is a centralized IP routing network used by GSM operators to transport MMS and other mobile data services. Syniverse is the GRX provider for all major North American GSM operators and also provides GRX services in Asia Pacific and the Middle East.

"Syniverse and OpenMIND support the industry's efforts to provide worldwide MMS interoperability to stimulate widespread adoption of this high value service," said Michael O'Brien, vice president - marketing, Syniverse. "Due to the complexities associated with implementing MMS and the variations of multimedia messaging service centers in use today, Syniverse's long-term experience as a hub network provider and interoperability expert will help mobile operators open up messaging quickly and efficiently."

Syniverse will use OpenMIND's Message-OS Platform MMS applications to manage the routing, interworking and billing of MMS messages being sent between operator MMSCs (multimedia messaging service center) both nationally and internationally.

"OpenMIND is delighted to partner with Syniverse to provide their mobile operator customers with enhanced MMS interoperability services. Our Message-OS Platform allows Syniverse to meet the existing MMS business requirements and also is highly expandable for future business requirements," said Alex Duncan, CEO, OpenMIND Networks.
