service offers exceptional value and flexibility as it offers the unique
possibility of being able to add multiple users to share a price plan.

"Mobile professionals today are busy enough, and the extra time they
spend looking for hotspots or waiting for downloads on slow connections is
time they don't have," said Jim Lahey, Vice President EMEA for Sierra
Wireless. "The launch of the AirCard 850 on the Orange UK network,
following on the recent launch of the card with Orange France, is an
example of the leadership position Orange and Sierra Wireless have taken in
providing business customers with effective, efficient access to the
information they need."

The AirCard 850 is a 3G wireless WAN Type II PC Card with a slim
design that allows users to conveniently store the card inside the laptop
with the antenna attached. Fully functional on 3G+, 3G, EDGE, and GPRS
networks, the AirCard 850 utilizes the 2100 MHz 3G frequency band common to
European 3G networks, offering average data rates of 1 Mbps, with bursts up
to 1.8 Mbps on the Orange 3G+ network. In areas where 3G+ or 3G network
coverage is not available, these cards will connect to EDGE and GSM/GPRS
networks and enable international roaming on all four frequency bands (850,
900, 1800, and 1900 MHz) used worldwide.
