3Com Introduces the Go Anywhere, Do Anything Mobile Connectivity Solution

NEW YORK — June 22, 1999 — 3Com Megahertz 56K Global GSM & Cellular Modem PC Card Delivers Fast, Reliable and Simple Connections Around the World

3Com Corporation (Nasdaq:COMS) today introduced the 3Com(R) Megahertz(R) 56K(1) Global GSM & Cellular Modem PC Card — a feature-rich connectivity solution for today's mobile professional. Building upon its award-winning PC Card and modem technology, 3Com has delivered a truly global modem with the advanced features customers expect from the leader in network connectivity.

The 3Com Megahertz Global GSM & Cellular Modem PC Card is a modem that gives laptop users fast and reliable access to corporate networks and the Internet — whether connecting via standard phone lines or the most popular cellular and GSM phones. It also features 3Com's durable XJACK(R) connector for easy, dependable phone connections without additional cables. The XJACK connector has been redesigned to improve reliability, with a sturdier form factor and built-in lights to indicate connection status.

"In the increasingly global marketplace, mobile workers in the 21st Century must be able to travel anywhere in the world. 3Com is committed to supplying our customers with first class connectivity solutions wherever business takes them," said Sylvio Jelovcich, director of worldwide product marketing for 3Com's Business Connectivity Group. "3Com's next generation modem supports a multitude of landline and mobile phone systems, and provides easy connections in over 250 countries and regions worldwide."

The 3Com Megahertz Global GSM & Cellular Modem PC Card features several exclusive technologies that distinguish 3Com's connectivity products as best-of-class solutions, including:

— Exclusive Line Probing technology negotiates line impairments to deliver high modem throughput and reliable connections — even on the worst lines.

— WorldPort(TM) country selection software allows users to configure the modem for phone lines worldwide by simply clicking on the appropriate flag or country name.

— DynamicAccess(R) Mobile Connection Manager delivers one-step configuration, saving time and lowering total cost of ownership for IS managers and mobile workers.

— GSM Connection Manager software works with mobile data applications from Nokia and Ericsson to automatically route data calls to a GSM handset if one is present — without reconfiguring the system.

The platform independence of 3Com's new offering enables guaranteed compatibility with laptops running Microsoft Windows 95/98/2000 and NT 4.0, Mac OS, Linux and DOS. This operating-system independence, coupled with product localization in 18 languages, allows customers to standardize on one product — even in multi-platform and global environments.

The Global GSM & Cellular Modem PC Card is slated for worldwide availability in mid-July at an estimated list price of $ 229. 3Com supports all of its PC Cards with an industry-leading lifetime limited warranty. Additional information about this product can be found at http://www.3com.com/mobile.
