FOMA, officially short for Freedom of Mobile Multimedia Access, is the brand name for the 3G services being offered by Japanese mobile phone operator NTT DoCoMo.
FOMA was the world's first WCDMA 3G service when launched in 2001. However, FOMA's variant of the technology is currently incompatible with standard UMTS, including Vodafone Japan's 3G service, and hence does not provide global roaming.
FOMA has not been particularly successful.
