Singapore Appoints Syniverse as Sole Provider of National Number Portability.

Syniverse Will Be Licensed to Develop and Administer a Centralized Database as Well as Establish Service Agreements with All Singapore Operators

TAMPA, Fla. -- Syniverse Technologies (NYSE: SVR), a leading provider of technology and business solutions for the global telecommunications industry, announced today that Infocomm Development Authority of Singapore (IDA) has appointed Syniverse as the country's only number portability centralized database administrator. Syniverse will be awarded the license to provide number portability solutions to Singapore's telecommunications operators, and will establish number portability service agreements with all of Singapore's telecom providers.

The license will allow Syniverse, as an operator-neutral third party, to administer the database and provide number portability services to operators for seven years.

The number portability database will facilitate the seamless transfer of telephone numbers when subscribers wish to keep their numbers but change service providers between two mobile operators. Also included in the license is the right to provide number portability services to fixed-line operators and others, such as VoIP and wireless broadband operators, should the need arise. Singapore Computer Systems (SCS), a Singapore-based information and communications technology service provider, will provide local support for Syniverse's number portability solution.

Singapore's new centralized database is expected to be in place by the second quarter of 2008, at which time service providers will be expected to meet the IDA's new number portability regulations. According to the IDA, Singapore's operators serve more than six million subscribers.

"Singapore has one of the most sophisticated telecommunications systems in Asia, and Syniverse is honored to have been chosen by the IDA to provide its telecom operators with even more robust local number portability services than are already available," said Tony Holcombe, President and CEO, Syniverse. "Syniverse has an excellent track record over many years in building and maintaining sophisticated systems that interconnect different service providers' networks, and we look forward to providing Singapore's telecom industry with a solution that will be efficient and cost-effective for the operators as well as beneficial for their subscribers."

Raymond Cheung, Executive Vice President and CEO-Asia Pacific, Syniverse, said the license award from Singapore strengthens Syniverse's position as a global leader in end-to-end number portability solutions.

"We already provide number portability services to many operators around the globe, including most mobile operators in the United States; all mobile operators in Canada and the United Kingdom; and select operators in Hong Kong, Taiwan and Macau. We continue to strive to expand Syniverse's footprint in this area as more and more countries require their telecommunications providers to implement number portability solutions," said Cheung.

Singapore was one of the first countries to implement number portability in 1997 and is respected as a leader in providing this valuable service to subscribers. The move to a centralized database solution further demonstrates Singapore's leadership in providing leading-edge telecommunication services to subscribers across the industry.
