LONDON, September 13 /PRNewswire/ --

NeuStar, Inc. (NYSE: NSR) today announced that it has helped leading UK
network operator 3 to bring the popular Yahoo! Messenger instant messaging
(IM) service to 3's mobile customers in the UK, enabling users to be online
with friends and family at any time from anywhere. 3 chose NeuStar's
industry-leading Mobile Messaging Gateway solution to implement the roll out
of Yahoo! Messenger across its subscriber base.

NeuStar has a longstanding relationship with 3, having implemented the
rollout of 3's popular Windows Live Messenger service in August 2006. In June
2007 alone, 133 million messages were sent across the 3 network via Windows
Live Messenger.

Allen Scott, General Manager of NeuStar Next Generation Messaging, said:
"Mobile IM is a technology whose time is now. Forward-thinking operators like
3 have seen the opportunity, seized it, and are reaping the rewards of
additional data use and increased customer loyalty. The success of 3's
Windows Live Messenger service prompted 3 to offer its customers additional
IM solutions -- in this case, Yahoo! Messenger. We are pleased that the
positive experiences 3 has had working with NeuStar in the past have enabled
us to partner with them to further raise the profile of mobile IM."

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.

3 launched Yahoo's mobile IM service to its customers earlier this month,
building on the success of 3's popular Windows Live Messenger service.
Subscribers to the 3 network now will be able to send and receive instant
messages free for life with any contract through the Yahoo! and Windows Live
Messenger services.
