Telcordia Enables Total Call Mobile's Entrée into Prepaid Wireless

Hosted Solution Provides Seamless Path to MVNO Success

PISCATAWAY, NJ - May 9, 2006 -- Telcordia (www.telcordia.com) today announced that Total Call Mobile (totalcallmobile.com), a provider of high-quality mobile telecommunication services for business and residential customers, has selected the Telcordia Hosted Solution for Mobile Virtual Network Operators (MVNO) to support the launch of its prepaid mobile phone service.

"We are pleased that Telcordia could provide a proven solution to support our deployment of our new offering and enable us to launch the prepaid mobile service in less than 90 days," said Mark Leafstedt, CEO of Total Call Mobile. Total Call Mobile is the premier provider of International Direct Dial mobile service. The company, which targets multi-cultural ethnic groups in the U.S., has nationwide coverage available with the choice of either monthly or commitment-free prepaid plans.

Total Call Mobile selected Telcordia for its proven track record and its ability to assist in rapidly and cost effectively deploying prepaid services in the most reliable, secure and profitable manner.

"Total Call Mobile has identified a market that is incredibly loyal and until now has been largely untapped," said Doug Patterson, Vice President, Telcordia Hosted Solutions. "Telcordia's comprehensive product portfolio provides a seamless solution that helps companies like Total Call Mobile expand its business plans to better serve its customers, drive revenues, and expand its offers."

MVNOs are growing in popularity in the U.S. and around the world because of the benefits realized by all parties. Customers who might not otherwise purchase wireless services often sign up with MVNOs who tailor offerings to meet the specific needs of particular demographic groups. MVNOs, such as Total Call Mobile, benefit from the ability to extend their brands and open up new revenue opportunities without incurring the costs associated with building and managing prepaid network infrastructure.

The Telcordia Hosted Solution for MVNOs offers features such as real-time call management, which helps eliminate revenue leakage and facilitates a positive customer experience. The deployment of the Telcordia Hosted Solution dramatically reduces upfront capital investment in technical infrastructure and minimizes the need to hire skilled telecom resources. This enables companies to launch service quickly. Telcordia has signed 11 customers since launching its Hosted Solutions business last year. The Telcordia Hosted Solution includes elements of the Telcordia® Maestro™ IMS Portfolio of products, services, and applications that enable carriers to offer any service, over any network, via any device.
