RICHARDSON, Texas--(BUSINESS WIRE)--June 19, 2002

Inet Technologies, Inc. (Nasdaq:INTI), a leading global provider of communications software solutions for current- and next-generation networks, today announced that Smart Communications, Inc., one of the Philippines' leading wireless carriers, has successfully deployed Inet's GeoProbe Mobile(TM) solution.

GeoProbe Mobile is the enabling platform for Inet's Interconnect Management application suite for wireless carriers and will allow Smart to track Short Message Service (SMS) data traffic for rapid, accurate inter-carrier settlement.

"In the Philippines, the adoption of SMS communication by end consumers is growing very quickly," said Elie Akilian, Inet's president and chief executive officer. "To offer SMS as a global form of data communication, wireless carriers must support SMS interconnection. As a result of our ongoing research and development efforts in the areas of both wireless and data communications, we can provide our wireless customers with the tools to effectively manage interconnection settlement for SMS."

In the Philippines, regulation mandates that regional wireless carriers provide SMS interconnection. Inet's GeoProbe Mobile Interconnect Management application suite enables Smart to bill its interconnection partners for SMS traffic, as well as verify incoming interconnection invoices for SMS.

The GeoProbe Mobile helps Smart and other wireless carriers increase interconnection revenues, ensure accurate inter-carrier compensation and better manage cash flow with rapid settlement resolution. Inet's solution will also help ensure that the global evolution to next-generation wireless is a smooth transition for Smart, its interconnection partners and its subscribers.

The contract award from Smart was received through Inet's local distributor in the Philippines, SMS Global Technologies.
