Syniverse Signs Contract to Provide Wireless Number Portability Services to Canadian Carriers; Canadian Wireless Operators Engage Syniverse for Help Managing the Complexities of WNP.

TAMPA, Fla. -- Syniverse Technologies (NYSE:SVR), a leading provider of mission-critical technology services to wireless telecommunications companies worldwide, announced today it has signed a contract with a group of 10 Canadian wireless carriers to provide clearinghouse capabilities for the implementation of wireless number portability (WNP).

WNP will allow subscribers to keep their same phone numbers when transferring service between wireless carriers and networks as well as from a landline to a wireless number and vice versa. The Syniverse clearinghouse will handle the exchange of porting messages between the carriers and the Number Portability Administration Center, and serve as the centralized service bureau.

"Implementation of WNP is a complicated and time-consuming procedure," said Tony Holcombe, President and CEO of Syniverse Technologies. "Each of the Canadian companies is modifying its systems to create a 'ported' environment that involves network intelligence, switch upgrades and complex routing structures. We look forward to working with these leading Canadian wireless carriers and sharing our considerable expertise in wireless number portability."

WNP is scheduled to be available in most metropolitan areas in Canada beginning March 14, 2007.

Companies that are part of the group contracting with Syniverse for WNP services are Bell Canada with respect to its wireless business in Atlantic Canada, Bell Mobility, Fido, MTS Allstream Inc. (MTS), NorthernTel, Rogers Wireless, SaskTel, TBayTel, Telebec and TELUS.

Syniverse rolled out its market-leading number portability solutions in 2003 in the United States and provides number portability to most U.S. operators and now to most Canadian markets. Syniverse's wireless number portability solution is available for implementation around the world.
