NeuStar Delivers Live Content over Mobile IM with Mobinex

LONDON, United Kingdom, 8 February 2008  - NeuStar, Inc. (NYSE: NSR) today announced that it has partnered with Mobinex to deliver live data services over NeuStar's leading mobile Instant Messaging (IM) applications. The combined solution – which NeuStar will demonstrate at Stand #7C58 in Hall 7 at the Mobile World Congress in Barcelona beginning Monday, February 11 – will help mobile operators to promote new data services, increase average revenue per user (ARPU), and provide a richer mobile experience.

Mobinex, the global provider of on-device solutions, integrated its Smartface platform with NeuStar's mobile IM platform. The integrated solution will enable users to access data services whilst in an IM conversation through a one-click access button called "Live Tab." Users will be able to select from a range of services from downloads, ringtones, news, and mobile TV without leaving their IM session. In addition, operators will be able to deliver immediate data services within the IM client, delivering a better user experience whilst creating awareness around new operator services.

Allen Scott, general manager at NeuStar Next Generation Messaging, said: "Delivering a rich user experience is key to successful mobile services. IM is instant and 'chatty' by nature, and communicating users don't want to have to dip in and out of their IM session. In this way, the Live Tab solution is a great cross-selling opportunity for operators."
Scott continued: "NeuStar is enabling innovation in messaging, and we are working with developers to build new services and add value to existing services. These services will be integrated into a framework that can be accessed by more than 300 million mobile users worldwide through NeuStar's existing mobile IM solutions, which are currently live with more than 31 operators globally."

Murat Bahar, vice president of marketing at Mobinex, said: "With NeuStar, we have demonstrated the first embedded On-Device Portal functionality within a messaging application. I am sure that users will love it. It is both convenient and entertaining."

The Live Tab solution will be offered with the NeuStar Instant Messaging suite, and will be available on a series of J2ME-supported devices.

Working with more than 31 leading operators worldwide – including Vodafone, 3, Orange, Telecom Italia, Turkcell, and Beeline – NeuStar has the most field-proven launches of a range of mobile IM services. Building on its success and experience in the market since 1999, NeuStar has developed its pioneering services, working with operators and their users through focus groups, user forums, and research campaigns to provide a compelling service to meet all operators' demands and service models.
