Mobiletech Selects Diversinet’s Wireless Security For Its Mobile Productivity Products

mSuite Integrated Mobile Business Applications Delivers High-Value Information to Mobile Users Across Mobile Channels

ITU Telecom Asia 2002 – Hong Kong SAR, China / Toronto, CANADA – December 3, 2002 – MobileTech Ltd. and Diversinet Corp. (NASDAQ SmallCap: DVNTC), a leading provider of mobile commerce (m-commerce) security infrastructure solutions, today announced that MobileTech has licensed Diversinet’s Passport ONE(tm) wireless security software to secure its mSuite product line.

MobileTech’s mSuite collection of mobile business productivity applications is a comprehensive mobile business solution that systematically delivers customized, high-value information to mobile users with an easy-to-use experience across mobile channels. With crucial business applications such as mLogistics, mBanking and mBills, mSuite allows enterprises to bridge the information gap between headoffice and remote staff, thereby enhancing workflow and increasing overall effectiveness of business operations.

MobileTech is leveraging its strength in the China market and targeting the government, transportation and enterprise industries.

To control access to sensitive information, MobileTech employs Diversinet’s Passport ONE wireless security technology. The inclusion of Diversinet’s security provides an extra layer of security to mSuite applications, raising the standard of data protection.

“In today’s mobile economy, there is an enormous access barrier between enterprise backend information systems and field staff. While the Internet provides a ubiquitous network for a wide array of browser-based desktop applications, mobile staff does not enjoy the same benefits as their wireline counterparts,” said Sam LAM, CEO of MobileTech Ltd. “MobileTech enables enterprises to securely bridge the information gap, enhancing the workflow and increasing overall effectiveness of business operations.”

“With the number of mobile phone users in China at 176 million and climbing, nearly all forecasts indicate that the country will be the fastest-growing wireless market in the short term,” said Nagy Moustafa, President and CEO of Diversinet Corp. “MobileTech’s mSuite is ideally targeted at high-value mobile data users, such as enterprises, government and transportation mobile workers, who will require immediate access to sensitive corporate data, and that data needs to be secure.”

According to Yankee Group analyst Shiv Putcha, China represents a huge opportunity for technology providers. In June 2002, China’s Ministry of Information Industry (MII) reported that 176 million people in China now have wireless phone service, representing an increase of 31.35 million people in the first half of 2002. Industry projections show the total number of wireless users in China will rise to between 350 million and 500 million by 2005.
