When a recall mode is selected as the operation mode of a PHS terminal, recall data is generated. The recall data specifies another PHS terminal, a state wherein the other terminal enters a specific service area, and a message, for example, that "the other party has arrived (in the specific service area)" which is to be received from a server or the other terminal when the other terminal is set in the designated state. The recall data is set in the subaddress of a call set-up message and registered in the server or the PHS terminal. When the other terminal enters the specific service area, the server or the other terminal transmits the message to the PHS terminal in the recall mode. The PHS terminal displays the transmitted message on a display device. The user of the PHS terminal can thus know that the user of the other terminal has arrived in the specific service area and that communication with the other terminal is enabled. The state of the other terminal can therefore be recognized without requiring any operation on the part of the other party.
