VeriSign Provides Clearing, Settlement and Exchange Services to Third Largest GSM Wireless Provider in the United States

MOUNTAIN VIEW, CA (Marketwire) - VeriSign, Inc. (NASDAQ: VRSN), the leading provider of digital infrastructure for the networked world, today announced it will provide Dobson Communications (NASDAQ: DCEL), the third largest Global System of Mobile Communications (GSM) wireless provider with approximately 1.7 million customers in the U.S., with VeriSign® Settlement and Exchange Services beginning in April 2007.

VeriSign® Settlement and Exchange Services platform allows Dobson to know their financial position with roaming partners for voice and data traffic and provides customized Web-based reporting systems.

"The convergence of old and new services and a growing number of records from multiple roaming partners continues to increase the complexity of rating, billing, clearing and settling for rural wireless service providers," said Lee Huggins, vice president, VeriSign. "The unique ability to provide Dobson Communications with our bundled roaming and revenue assurance solution will help provide accuracy, timeliness and above all faster response to their customer needs."

VeriSign's GSM solution internationally complements its existing cellular intercarrier billing exchange record (CIBER) clearing business that has supported time division multiple access (TDMA) and code division multiple access (CDMA) operators for more than a decade. VeriSign currently provides clearing services to 35 carriers, 16 of which are GSM operators.
