VIVO CHOOSES INTELLISYNC EMAIL/DATA SYNCHRONZATION.

Intellisync Corporation (NASDAQ:SYNC), San Jose, Calif., a leading developer and marketer of wireless email and mobile software, has been selected as the mobility platform for VIVO, the largest operator of mobile telephony in the Southern Hemisphere, and one of the largest CDMA carriers in the world. VIVO, part of the Portugal Telecom and Telefonica Moviles groups, will license Intellisync mobile software to deliver push-based wireless email and data synchronization capabilities across a wide range of mobile device types to its more than 27 million customers in Brazil. VIVO is ranked as No. 10 in worldwide rankings of the largest global mobile carriers by RCR Wireless News with an estimated market share of 45% in Brazil. The company is present today in 19 Brazilian States plus the Federal District, corresponding to 86% of the Brazilian territory encompassing 83% of the country's GNP. The technological option of the company is CDMA, the basis for the third generation of mobile telephony, according to the International Telecommunications Union -- ITU.

Vivo Smartmail, "Powered by Intellisync," allows users to wirelessly access personal and enterprise e-mails based on Lotus Notes, Microsoft Exchange, POP3 or IMAP servers. The Intellisync technology allows continuous bidirectional synchronization, ensuring that any change in a user's handheld device (including contacts, email, calendar items and tasks) is automatically synchronized with the data on the user's personal computer.

"We believe that it [Smartmail] is a superior solution to some of the other competing solutions; it is more complete and is not tied to a specific terminal (device)," said Roger Sole, Vivo's director of business-oriented data solutions.

The solution will initially be released with the following PDAs offered by the operator -- the Harrier by Audiovox (Microsoft OS) and the Palm Treo 600 -- both devices offer a qwerty keyboard. "One of the advantages is that corporate users can integrate additional applications within the same device," added Sole. According to Sole, the initial target market will be large corporations. "After that, we will lead to offer the solution to SME's (small and medium size enterprises) and close to the end of the year we will target the independent professionals," he said.

"Intellisync is the wireless email provider of choice for the world's largest and most demanding mobile carriers, and we are thrilled to be selected as the primary wireless email provider for the largest mobile carrier in South America," said Clyde Foster, Intellisync's chief operating officer. "The agreement with VIVO represents a large win for Intellisync and its expanding global presence. Our comprehensive mobility platform and, ubiquitous device and application support make Intellisync an ideal partner for driving activations and revenue opportunities for VIVO."
