NeuStar and SFR Bring Windows Live Messenger to Mobile Phone Users in France

LONDON, November 28 /PRNewswire/ --

NeuStar, Inc. (NYSE: NSR) today announced that it has partnered with
leading mobile phone operator SFR to bring Windows Live Messenger to SFR's 18
million customers in France.

SFR customers now will be able to access Windows Live Messenger directly
from their mobile phones using the same login information and enjoying the
same feature-rich experiences and buddy lists that they would on their
desktop PCs. Users can download the service from the SFR website to a number
of mobile handsets.

NeuStar was selected by SFR to provide NeuStar's innovative Mobile
Messaging Gateway (MMG) solution, which enables operators to roll out
PC-based Instant Messaging solutions to the mobile environment quickly and
easily. The engaging MMG solution is familiar to users, and therefore
intuitive to use.

Allen Scott, general manager of NeuStar Next Generation Messaging (NGM)
said: "More and more operators across the globe are realizing that they can
generate revenue and user loyalty by rolling out mobile Instant Messaging
services to their customers. We knew that it would be rewarding to provide a
service to SFR because they always want to offer their customers the best
possible solution. It has been great working with them to bring this project
to fruition."

The SFR Windows Live Messenger service went live in August 2007.
