AeroMobile ™ becomes a member of the GSM Association

London, 7 March 2006 – AeroMobile, a joint venture between ARINC and Telenor, the leading developer of in-flight mobile (cell) phone services, is pleased to anounce that it has been granted membership of the GSM Association. AeroMobile’s membership of the GSMA is a further key step in AeroMobile’s market-leading progress towards implementation of operational services on aircraft in 2006.

AeroMobile is the first commercially available in-flight communications service which allows passengers to make and receive calls or SMS messages using their own handset. All calls are invoiced through their network provider, using roaming services, so membership of the GSM Association (GSMA) is an important step forward for AeroMobile. The GSMA membership allows the use of GSMA roaming agreements and algorithms, and means that AeroMobile’s network can be made available through International Roaming Agreements to any other GSM operator worldwide.

“Becoming a GSMA member is a major milestone for us and clearly demonstrates the maturity of AeroMobile both with regard to our aircraft and ground infrastructures” said Graham Lake , President, AeroMobile. “Acceptance from the GSM Association is a quality mark and shows that AeroMobile is a fully integrated and independent GSM operator. The commercial use of GSM services onboard aircraft has taken another step forward and will soon be a reality for all passengers.”

GSMA Membership is open to licensed 2G and 3GSM mobile network operators committed to implementing the GSM family of technologies (GSM, GPRS, EDGE and 3GSM) for digital wireless communications.

“The development of AeroMobile in an environment where there is currently no service will expand the service availability that GSM network providers can give to their customers and will allow them to look for increased roaming revenues. The customers will also benefit from being able to use their mobile phones on aircraft for business and leisure calls and messages. Further development of the AeroMobile service will also allow the use of PDA and other data exchange devices such as BlackBerrys,” added Lake.

AeroMobile officially became a member of the GSM Association on 3rd March 2006.
