With known information terminals, the method of inputting the telephone number or like information directly from a keyboard on the terminal does not require a specialized writing implement but there have been problems with this method such as input errors occurring easily and the time consuming process of inputting all items. The information terminal relating to the present invention includes a wire communication device which obtains a telephone number for wireless telephone communication via wire lines from management equipment which manages users, a control device which stores the aforementioned telephone number for wireless telephone communication, and a wireless communication device which conducts wireless communication using the aforementioned telephone number for wireless telephone communication, wherein registration of information such as the telephone number, encryption key, and the like can be conducted in a speedy and sure manner without necessitating human intervention. Also, there is little danger of the encryption key falling into other hands upon registration thereof, since the encryption key does not pass through a third party such as a dealer.
