Abstract: An SMS-based wireless value-added service implementation method and system. The method comprises the steps of: disassembling a wireless value-added service into command identifiers for commands and corresponding information bodies at the service provider side, said information bodies including information required for the commands and service related information; combining each of said command identifiers and corresponding information body into a command body, and inserting a logic sequence identifier that indicates the logic sequence of the commands into the command body, then assembling the command bodies into a short message. The service server sends the short message to the mobile terminal, and the interpretation program in SIM card of the mobile terminal interprets the short message into corresponding commands and information which have a logical sequence and can be executed in the mobile terminal. The mobile terminal executes the commands based on the logic sequence, and displays the information.
