Abstract
A communication apparatus such as a cellular phone is described in which a control unit judges, when an incoming call is received, whether a sounding unit or a vibrating unit is to be activated for announcing the reception of the incoming call. The control unit determines that the announcing of the reception is prohibited if the mobile communication apparatus is in a roaming area. When the announcing of the reception is prohibited, the control unit sends a message, showing that the reception of the incoming call is unavailable, to a calling party.
