In a handsfree system, when a mobile phone receives an incoming voice call from a mobile phone network while data communicating with a device that is an in-vehicle device (handsfree device), the mobile phone is automatically changed from a handset mode to a handsfree mode. Thereby, immediately after the mobile phone receives an incoming voice call from the mobile phone network, the mobile phone can be automatically changed from a handset mode to a handsfree mode without any user's operation.
