MOUNTAIN VIEW, CA–May 11, 2006 –VeriSign, Inc. (Nasdaq: VRSN), the leading provider of intelligent infrastructure services for the Internet and telecommunications networks, today announced that MetroPCS Communications, Inc., the innovative regional wireless service provider, is using VeriSign’s iRoam solution to power its new TravelTalk service.

“By using VeriSign’s iRoam service, MetroPCS can offer customers an added benefit to their flat rate, unlimited service calling plans,” said Roger Linquist, president and CEO of MetroPCS. “TravelTalk allows customers to enjoy wireless freedom while easily managing their expenses.”

The iRoam solution provides operators with the ability to generate real-time billing for pre-paid subscribers that are traveling.
