A method and apparatus for an enhanced SMS can include receiving a short message, checking whether the received message is user data, processing the user data by referring to previously received control data if the received message is user data, and outputting the processed user data to a screen. The short message and SMS can be used in all mobile telecommunication devices. Further, such a short message and SMS can be encapsulated to the conventional short message service (SMS) protocol, and thereby used in a system or a protocol without change.
