To achieve a quick emergency call even when rewriting of a SIM is performed.SOLUTION: A radio communication device comprises: a storage unit; a communication unit that performs radio communication with a network; a SIM interface for inputting/outputting information with respect to a SIM; and a control unit that acquires connection destination information in connecting to the network through the communication unit, stores the connection destination information in the SIM, and stores the connection destination information in the storage unit. The SIM is configured to rewrite the information stored in the SIM through communication so that a common carrier is switched. When the connection destination information is not stored in the SIM in issuing an emergency call through the communication unit, the control unit performs processing for connecting to the network by using the connection destination information stored in the storage unit.SELECTED DRAWING: Figure 3

    【課題】SIMの書き替えが行われる場合であっても速やかな緊急通報を実現する。【解決手段】無線通信装置は、記憶部と、ネットワークとの無線通信を行う通信部と、SIに対する情報の入出力を行うためのSIMインターフェイスと、前記通信部を介して前記ネットワークに接続する際に接続先情報を取得し、前記接続先情報を前記SIMに格納するとともに、前記接続先情報を前記記憶部に格納する制御部とを備える。前記SIMは、前記SIMに格納された情報を通信により書き替えることにより、通信事業者の切り替えが行われるように構成される。前記制御部は、前記通信部を介して緊急通報を行う際に前記接続先情報が前記SIMに格納されていない場合、前記記憶部に格納された前記接続先情報を用いて前記ネットワークへの接続処理を行う。【選択図】図3
