Mobile paging telephone with an automatic call back function

When a page message containing a caller ID is received from a caller, a call back message containing one of prepared response messages is transmitted to a call number associated with the caller ID. For this, the system displays the prepared response messages and prompts the user to select one of them. A call back message is compiled from a call back number associated with a caller ID contained in the page message and the selected response message. The call back message is transmitted to the call back number. The compilation of call back message is performed such that the format of call back message is adapted to the type of the caller's communication device associated with the caller ID.
