When a recall mode is selected as the operation mode of a PHS terminal (PS1), recall data is generated. The recall data specifies the other party (e.g., a PHS terminal (PS2)), a state wherein the other party enters a specific service area, and a message "the other party has arrived at Y station (in the specific service area)" which is to be received from a server (5) or the PHS terminal (PS2) when the other party (PS2) 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 (5) or the PHS terminal (PS2). When the PHS terminal (PS2) enters the service area of a public base station (2c) (designated state), the server (5) or the PHS terminal (PS2) transmits the message to the PHS terminal (PS1) in the recall mode (designated action). The PHS terminal (PS1) displays the transmitted message on a display device (19). The user of the PHS terminal (PS1) can know that the user of the PHS terminal (PS2) has arrived at Y station and that communication with the other party (PS2) is enabled. The state of the other portable information terminal can be recognized without requiring any operation to the other party. <IMAGE>
