TU-KA, an affiliated company of KDDI, is a 2G Personal Digital Cellular cellular operator who did not apply a 3G license. Telephone companies KDDI Corporation(1) au/KDDI and Vodafone Japan's wireless data services have been proved to be more successful than DoCoMo's i-mode. More detailed studies can show that Vodafone Japan was more successful in 2001 and 2002, while au/KDDI has been more successful since. The statistics also show huge advantage against DoCoMo and Vodafone Japan. Recently DoCoMo is forced to slice it FOMA packet prices up to 50% in an effort to hold the out-going customers. DoCoMo will also follow the suit to provide flat data rate.
