In a radio display pager, a paging signal from a transmitter station is received and checked by a decoder to see if it contains a pager's first identifier or a pager's second identifier. The first and second identifiers are respectively followed by a caller's telephone number and a sequence of caller's message codes. If the decoder determines that the paging signal contains the first identifier, the caller's telephone number is displayed and if it determines that the paging signal contains the second identifier, the subsequent message codes are used as address pointers to read alphanumeric data from a memory to reconstruct a caller's message, which is displayed.
