Mobile Messaging Numbers Continue to Skyrocket, VeriSign Reports

MOUNTAIN VIEW, CA, Aug 27 (MARKET WIRE) --
VeriSign, Inc. (NASDAQ: VRSN), the trusted provider of Internet
infrastructure services for the networked world, announced today another
record-breaking quarter for mobile messaging, based on the latest
quarterly index of mobile messaging statistics compiled by VeriSign's
Messaging and Mobile Media division.

Through June 30, 2008, VeriSign's combined mobile messaging networks
delivered 95.4 billion Inter-carrier Short Message Service (ICSMS)
messages in the calendar year, eclipsing the previous record for text
messages in the first half of any year. VeriSign's network also set a
single-day record by enabling 648 million texts over a 24-hour period and
a one-hour record of 42 million messages.

All told, VeriSign's combined mobile messaging networks enabled more than
52 billion messages in Q2 2008, up more than 20 percent from the previous
quarter. VeriSign facilitated an average of approximately 572 million
messages per day in Q2 2008, compared to approximately 476 million
messages per day in Q1 2008 and approximately 230 million messages per
day in Q2 2007. These record-breaking numbers provide additional evidence
to support VeriSign's projection earlier this year that its combined
mobile messaging networks will enable close to 200 billion total messages
worth more than $7 billion in revenue to VeriSign customers by the end of
the year.

"As mobile messaging usage continues to grow at a rapid pace, consumers
and operators are demanding secure and reliable delivery of their
messages. VeriSign continues to raise the bar by providing unparalleled
service and delivery at scale with 99.999-plus percent availability in
the past 18 months and 100 percent availability for the last nine
months," said Charles Landry, vice president and general manager,
Products and Innovation, for VeriSign's Messaging and Mobile Media
division. "This is critical, because as texting traffic will only
continue to grow, service providers and end users will need a network
that they can count on."

VeriSign offers one of the most robust, scalable and reliable mobile
messaging delivery engines in the world, connecting to more than 600
carriers and reaching more than 2.4 billion wireless subscribers across
carrier, enterprise, and media/entertainment networks. VeriSign's combined
mobile messaging networks power inter-carrier mobile messaging for seven
of the top ten wireless carriers in North America and many other major
operators throughout the world. The network generates billions of dollars
in revenue for its customers.

Application to person messages (A2P), such as news alerts, ring tones,
promotional video clips, and enterprise messages sent to mobile users,
also rose sharply in Q2 2008, from approximately 186 million messages in
Q1 2008 to approximately 249 million messages in Q2 2008, an increase of
close to 33 percent. Contributing to this growth were increases in the
steady adoption of mobile banking services by VeriSign's customers,
including 7 of the top 10 banks in the United States and a 30 percent
increase in traffic volumes for standard and premium A2P traffic messages
carried in Europe.
