In a mobile phone (1) that is changeable to a plurality of styles, when connecting a call in response to an originating call or an incoming call by a wireless communication section (14), a central control section (11) controls a style detecting section (24) to detect a current style, and judges whether or not the call should be restricted by referring to an operation mode information storage section (M5). The central control section (11) then restricts the call based on this restriction judgment result and the detection result from the style detecting section (24). Also, the central control section 11 drives a notifying section (20) to give a notification indicating that a call in a certain style is restricted.
