Vancouver, Canada and London, UK-November 21, 2006

Sierra Wireless (NASDAQ: SWIR - TSX: SW) and Orange Business Services today announced that the Sierra Wireless AirCard 850 Mobile PC Card is now available in the United Kingdom. The card is the first 3G+-enabled card offered by Orange and offers mobile professionals a proven, reliable wireless connection in advance of Orange’s planned 3G+ network upgrade, expected to begin in Q1 2007. The AirCard 850 Mobile PC Card is available through Orange retail, online, and business channels.

The AirCard 850 Mobile PC Card with the Orange Business Everywhere service will allow roaming on the best available 3G+ and 3G wireless networks across Europe, and is fully compatible with EDGE and GPRS networks around the world, providing business travelers with the ability to maintain close contact with colleagues and clients while away from the office.

Orange Business Everywhere customers in the UK benefit from one contract, one customer service point of contact and one bill, regardless of the mobile data network (3G+, 3G, EDGE/GPRS, WiFi or broadband) used. The 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.
