FOR IMMEDIATE RELEASE

LEUVEN - BELGIUM - December 10th 2003 - OPTION (Euronext: OPTI), the wireless technology company, today announced that its new GlobeTrotter Combo has been chosen by T-Mobile, one of the world's leading mobile communications companies and subsidiary of Deutsche Telekom (NYSE: DT), to extend its range of mobile data services to the German market.

Option announced GlobeTrotter Combo, the data card combining GSM/GPRS and Wireless LAN (WiFi) technologies, at ITU TELECOM WORLD in October 2003. The card was launched to satisfy the market need for the mobile professional to take full advantage of the growing number of WLAN & WiFi services being bundled by mobile operators, of which T-Mobile is a leading player.

Last year T-Mobile already selected Option's GlobeTrotter GSM/GPRS only card. Both data cards are sold under the T-Mobile brand.

Jan Callewaert, CEO at Option: "I am very pleased for the continuing business with T-Mobile in taking our new product GlobeTrotter Combo. A strong track record in developing and manufacturing wireless data cards and a solid support service were, once again, the main reasons for choosing Option."

T-Mobile's choice for the GlobeTrotter Combo clearly shows that the market is ready for the next generation of wireless data cards. Until recently GPRS was the only widely available choice for wireless data. Now we see WiFi hotspots at destinations like hotels, conference centres and corporate premises and in transit locations like airports, train stations, public buildings and marinas. With roaming agreements between GPRS and WiFi becoming commonplace the GlobeTrotter Combo will be great market success.
