AT&T Wireless Services Inc. offers a high-speed wireless data service called Mmode. The service is based on NTT DoCoMo Inc.s Imode service, which is popular in Japan. DoCoMo, which owns 16 percent of AT&T Wireless, was integral in designing Mmode.
Mmode runs on the GPRS (General Packet Radio Service) network and is available in markets that AT&T has upgraded to GPRS, including Chicago; Detroit; Las Vegas; Phoenix; Miami; and Orlando, Fla. The Mmode screen is basically a portal, with links to various categories ranging from information to games.
Mmode comes in three packages. The Mini plan costs $2.99 per month, plus 2 cents for each kilobyte of data. The Mega plan comes with 1MB of data and costs $7.99 per month, with each additional kilobyte costing 1 cent. The Max plan, which comes with 2MB of data, costs $12.49 per month and costs a penny for each additional megabyte.
