NeuStar Builds 3’s Mobile IM Footprint in Asia

LONDON, UK, 12 November 2007

NeuStar, Inc. (NYSE: NSR) today announced that it has facilitated the rollout of Windows Live Messenger with 3 Macau as part of 3’s popular X-Series brand, building upon the success of the mobile IM service with 3 Hong Kong.

Expanding on its successful partnership with the 3 Group in Europe – specifically in the UK, Ireland, Sweden, Denmark, Austria and Italy – NeuStar worked with 3 Hong Kong and 3 Macau to implement and launch the popular mobile IM service. As a result of these new partnerships, 3’s subscribers are able to access Windows Live Messenger to communicate with friends and family from their mobiles.

Allen Scott, general manager of NeuStar Next Generation Messaging, said: “Innovative operators like 3 Hong Kong and 3 Macau have recognized the value of providing mobile IM services to their users and giving customers new and innovative ways to communicate. We are delighted that our successful relationship with 3 is being strengthened in Asia.”

Scott continued: “We are now working with more than 30 operators worldwide to make mobile Instant Messaging a reality. This year, we have seen many leading operators successfully launch these services to their user bases. Mobile IM is poised to become a truly mainstream service in 2008.”

NeuStar has a longstanding relationship with 3. For example, NeuStar implemented the rollout of 3 UK’s Windows Live and Yahoo! Messenger services. Also, 133 million messages were sent across the 3 network via Windows Live Messenger in June 2007 alone.

NeuStar works with more operators worldwide than any other company offering Mobile IM services. The success of the Windows Live Messenger service on 3’s network is further proof that mobile consumers will readily adopt familiar services that are easy to use and suitable for the mobile environment as operators make these services available.
