Telcordia MVNE Momentum Continues;
Company Powers new US-based KDDI America MVNO

PISCATAWAY, NJ - June 25, 2007 - Telcordia Technologies (www.telcordia.com), the leading global provider of telecommunications software and services, has today announced that it has enabled KDDI America, Inc. (www.kddimobile.com), a wholly owned subsidiary of KDDI Corporation, the largest international telecommunications company in Japan, to launch a MVNO that offers unparalleled choice of prepaid services and tariffs targeted to Japanese communities in the United States.

KDDI America will be relying on the Telcordia Hosted Solution for MVNOs, which offers high-quality, pre-paid and post-paid wireless services without having to own or manage a network. KDDI America will specifically be providing a real-time pre-paid service that includes flexible rates on calls to and from Japan. Telcordia has a unique MVNE heritage and has driven the launch of numerous MVNOs including Virgin Mobile USA, Kajeet, Disney Mobile and Flying J, based on its ability to lower the entry barrier and speed time to market in the dynamic business segments which are vital to the success of MVNOs.

KDDI America will benefit from expanded geographical reach and rapid time to market in the United States, coupled with lowered cost of entry and Telcordia's capability to provide sophisticated rating that opens up a spectrum of tariffs that offers KDDI America subscribers exceptional choice.

"There are unique synergies between KDDI America's approach of taking advantage of opportunities to expand its subscriber base and Telcordia's experience in providing the innovation, experience and reach that transforms these opportunities into profitable new businesses," said Cathy McMahon, Executive Director, Hosted Solutions, Telcordia. "KDDI America subscribers can look forward to real benefits from Telcordia's involvement as we continue to help MVNOs seize the moment and capitalize on new subscriber segments and geographical markets."

The Telcordia Hosted Solution for MVNOs is powered by the Telcordia Service Delivery Suite and the Telcordia® Real-Time Charging solution, which enables the rapid introduction of new business models while facilitating a real-time, interactive customer experience. The deployment of the Telcordia Hosted Solution for MVNOs helps to dramatically reduce upfront capital investment in technical infrastructure, minimize the need to hire skilled telecom resources and enable companies to launch services quickly.

Telcordia has recently expanded its Hosted Solution offering to include a wide and deep selection of off-the-shelf content, including more than 25,000 ringtones, wallpapers and games, as well as dynamic content such as real-time news feeds. Telcordia MVNO customers can also now provide a handset client, which resides on subscriber's phones to provide user friendly access to static and dynamic content.
