VeriSign Launches Mobile Alerts Service for Wireless Carriers That Want to Offer Real-Time Weather, News, Sports, Stocks and Digital Content

WeatherBug to Be First Premier Content Provider Offering SMS Weather Alerts to Midwest Wireless Subscribers

SAN FRANCISCO, CA—CTIA Wireless IT & Entertainment 2005—September 28,  2005—VeriSign, Inc. (Nasdaq: VRSN), the leading provider of intelligent infrastructure services for the Internet and telecommunications networks, today introduced VeriSign® Mobile Alerts Service, which features tailored mobile content that is delivered to mobile devices using a Short Messaging Service (SMS).

The first premium content provider contributing alerts is WeatherBug, the leading provider of weather information services in the United States, and the first service customer is Midwest Wireless, which offers weather alerts as part of a mobile alerts service that includes stocks, sports, news and horoscopes for $3.95 a month.

“The launch of the VeriSign Mobile Alerts Service will enable customers to receive timely and relevant information on their mobile devices, wherever they are, whenever they need it,” said Vernon Irvin, executive vice president and general manager, VeriSign Communications Services.  “We are pleased to be working with WeatherBug and Midwest Wireless, which are playing an important role in helping evolve mobile devices into information portals.”

The VeriSign Mobile Alerts Service is a managed service that provides subscribers with up-to-date information about weather, news, sport scores, stock quotes and horoscopes. This premium content is delivered to mobile devices via a text message, sent out upon a customer’s request when information is updated or at regularly timed intervals. The service is part of the company’s Mobile Messaging Platform (MMP), which provides carriers with a single, secure architecture to deliver enterprise-wide messaging and interactions and efficiently handles diverse wireless technology and carrier integration. The platform features content and applications that enable businesses and consumers to conduct transactions and communicate using different devices and platforms.

Working with VeriSign, WeatherBug will leverage its nationwide network of 8,000 WeatherBug Tracking Stations and issue 24-hour forecasts, 3-day forecasts and live local weather conditions to Midwest Wireless subscribers. Consumers, businesses and government agencies, including the National Weather Service, depend on the WeatherBug neighborhood-level network data.

“WeatherBug is the only weather source that can provide truly live, local data at the neighborhood level.  Alternative sources are based upon computer modeling from hourly airport data.  Weather conditions can differ greatly in intensity, even over a few miles distance, so this precision and accuracy is important to VeriSign carrier customers and end users who often rely upon their wireless service as their ‘lifeline’ – especially during extreme weather seasons,” said Andy Jedynak, senior vice president and general manager, WeatherBug.  “By joining forces, VeriSign and WeatherBug enable consumers to better plan their days.”

“The combination of wireless communications and real-time local and national weather information enables us to offer a value-added service and build customer loyalty. Offering digital content that changes as often as the weather does can improve customer satisfaction and be a competitive differentiator,” said Scott Bergs, chief operating officer for Midwest Wireless.
