    • GSM Association Press Release
    • INTERSTANDARD ROAMING GOES GLOBAL AS FIRST GSM-CDMA AGREEMENT KICKS OFF IN KOREA
    • World Cup visitors can use GSM service on CDMA handsets
    • 15 January 2002 - LONDON, UK: The GSM Association, the world's leading wireless industry organisation, has announced the first successful GSM-CDMA inter-standard international roaming. The wireless technology breakthrough was achieved with an unprecedented cooperation between the GSM Association's Global Roaming Forum (GGRF), Korean CDMA operator Korea Telecom Freetel (KTF) and Bouygues Telecom, which operates the French GSM 1800 network. The GGRF is driving inter-standard roaming, and the commercial launch enables KTF to provide roaming services to visiting GSM subscribers from networks with a roaming agreement in place with KTF. The first of these is Bouygues Telecom. The partnership is pertinent and timely as the French operator's home country will be defending the FIFA World Cup in this year's football tournament, hosted in Korea and Japan in the coming months. KTF has developed intelligent handsets that accept the visiting GSM SIM card, so all personal information is still available to the roaming client, who also retains his GSM number. With the World Cup kicking off in June, KTF anticipates a potential 100,000 GSM roaming clients during the year.
