Wireless Content Offering Allows Wireless Subscribers to Unwire the Web And Deliver Information On Demand

ATLANTA, Sep 24, 2002 /PRNewswire-FirstCall via COMTEX/ -- Numerex Corp. (Nasdaq: NMRX) today announced the availability of a new mobile messaging offering, WebTap(TM), which can transform Web content into customized wireless services for SMS-enabled mobile phones.

Through an agreement with Voxline Communications, Inc., Numerex can now offer its Data1Source(TM) wireless carrier customers a Short Message Service (SMS) solution that addresses the information needs of their subscribers with the use of a new tool that unwires the Web for content delivery, along with pre-formatted content via The Associated Press.

"As the number of mobile subscribers in the U.S. continues to climb, on- the-go users are relying more on their mobile phones for timely wireless communication," said Greg Hull, vice president of marketing and business development, Numerex Corp. "Numerex has experienced rapid growth in text messaging usage, with a 36 percent increase in the number of text messages sent over our Data1Source SMS network in the last thirty days alone. Through WebTap(TM), mobile users can stay current throughout the day by receiving the latest breaking news pertaining to their own interests, whether that's financials, politics, technology or entertainment on demand, straight to their wireless phone."

Data1Source's wireless content service offering now makes it possible for users to get local news, weather forecasts or stock quotes at specified times every day via SMS messages, all controlled and managed by the user. Users select the Web content they want to unwire, and the information is then extracted from the Web and recast in structured documents (tailored to each individual's needs) and made accessible instantly for any mobile phone.

"We have good reasons to believe that our innovative content applications will change the way people use their cell phones today. Partnering with Numerex will give us the right leverage to make this happen for millions of mobile users," commented Sandor Fejes, chairman and CEO, Voxline Communications, Inc.

According to a recent SMS report by the Yankee Group, SMS revenues in the U.S. are expected to reach $4.5 billion or nearly 4% of total wireless voice and data revenues, within the next five years. Information alerts and branded content (both push and pull) are expected to warm consumers and business users to SMS, and drive traffic and revenues for the carriers.
