Acision Powers Advanced Messaging and Charging at Tata Teleservices for Tata Indicom and Tata DOCOMO

MOBILE WORLD CONGRESS, BARCELONA, Spain, February 16 - Acision, a world leader in mobile data, today announces that
Tata Teleservices, one of the fastest growing dual technology telecom service
providers in India, has selected Acision SMSC, Acision MMSC, Acision Business
Tools, and Acision's mobile data charging solution for its brands - Tata
Indicom (CDMA services) and Tata DOCOMO (GSM services).

Tata Teleservices Limited wanted to work with a strategic
partner to provide value-added services that will support the service
provider in increasing the revenue potential sitting in both its networks. As
Tata's incumbent messaging supplier since 2004, Acision was selected because
of its ability to offer high-performance, scalable mobile data solutions that
are focused on supporting Tata Teleservices current and future business
strategy and help its services stand out in an increasingly competitive
Indian market.

The new contract includes capacity expansion on the Acision
SMSC and Acision MMSC, with the aim of increasing Tata's text and multimedia
messaging traffic volumes by up to 90%. Tata Teleservices will also have the
ability to view information and report on data usage and performance across
all its messaging services with Acision Business Tools. In addition, Tata
will deploy advanced, real-time rating and charging with Acision's mobile
data charging solution, giving the operator access to accurate account
information. This will also give Tata Teleservices the control to reduce
exposure to revenue leakage and secure the network against the threat of
prepaid fraud.

"Partnering with Acision has given Tata Teleservices a strong
and competitive advantage in the messaging VAS space over its competitors,"
said Mr. A G Rao, Chief Technology Officer and President, Enterprise
Business, Tata Teleservices Limited.

"Analysing data in real-time, using Acision Business Tools,
will help us serve the customer more efficiently. Today those businesses that
operate in real-time using predictive technology methods lead the way in
winning customer loyalty and customer satisfaction. While selecting a partner
for deploying messaging solutions on our GSM network, we were confident that
Acision was the right technology partner to replicate the success that we
achieved using their tools on our CDMA network. With Acision's innovation and
expertise, Tata Teleservices is on track to establish itself as the best
telecom network provider in India," Mr Rao added.

Rory Buckley, CEO at Acision, commented: "Acision is proud to
support Tata Teleservices to meet their ambitious business plan to achieve
profitable and sustainable growth as the company moves forward. This win
reaffirms our track record and strong commitment to Tata and demonstrates our
ability to rollout innovative messaging and mobile payment services."
