Business Editors/High-Tech Writers

EL SEGUNDO, Calif.--(BUSINESS WIRE)--Sept. 16, 2003

Infonet Services Corporation (NYSE:IN), a leading provider of global communications services for multinationals, and KCOM Corp., a wholly owned subsidiary of KDDI Corp. (KDDI) -- Japan's second largest telecommunications carrier, today announced the availability of the high-speed AirH" (pronounced "Air Edge") mobile data service for enterprise users throughout Japan.

KCOM and Infonet have been providing mobile data solutions within Japan since 2000 with the release of its award-winning PIAFS service offering. The integration of the DDI POCKET's AirH" service provides users the ability to access enterprise content at speeds up to 128kbps -- twice the speed of the current offering. Utilizing Infonet's IP/MPLS network, enterprise customers are able to establish a closed network environment with the new offering, providing enhanced performance and a secured environment independent of the public Internet.

In keeping pace with the tremendous demand for high-speed mobile access technology in Japan, Infonet and KCOM have simplified the packaging of the service, offering a flat rate per month package for enterprise users. Users can select the phone price combination provided by DDI POCKET, Inc. (another subsidiary of KDDI) via one of many widely-available network interface cards, giving them a high-speed wireless alternative that provides high-quality access anywhere the AirH" service is available.

"The notebook computer and personal data organizer have become the mobile professional's briefcase -- providing essential tools for keeping them connected to their enterprise in real-time," said Marc Patterson, Vice President of Mobile Workplace Solutions for Infonet Services Corporation. "In the past, inherent speed and performance challenges limited the use of these mobile devices and left mobile professionals in Japan waiting for a next-generation solution that could provide a truly exceptional level of access speed and service. The integration of the AirH" service into our IP/MPLS environment provides enterprise customers high-speed on-demand access throughout Japan while ensuring their enterprise is secure."

"This collaboration is the next step in our initiative to provide solutions to the needs of wireless data and mobile users throughout Japan," remarked Yozo Takenouchi, Managing Director, KCOM. "Our collaboration with Infonet has provided a unique capability to our customers which is in high-demand."

The solution, while currently available only in Japan, provides an important component to the mobile data offering provided by leading providers in Japan. The offering further demonstrates the viability of next generation wireless technology, and positions Infonet for similar offerings in other parts of the world.
