Sega Mobile is Sega's mobile phone games service in the USA and Europe. Unlike its sister service in Japan Sonic Cafe, there is no monthly subscription - instead, games are bought on a one-by-one basis, usually from the network carrier such as AT&T or Vodafone. As such, it is available on the majority of phones that support J2ME on the carrier.
The game list is large, with a number of ports of classic games along with several new ones. The list below contains only the Sonic related games that have been released.
