In step S51, it is determined whether or not there is an association with the type of the USIM card. If it is determined that there is no association, the process proceeds to step S52 where the telephone directory data is read from the memory 15.
If the judgment is made at 51, the type of the USIM card cannot be matched at the time of reading, so that reading becomes impossible, and a message to that effect (reading impossible) is displayed on the display unit 18 at step S53.

As described above, according to the above-described portable telephone, the telephone directory data is registered in the telephone in association with the type of the USIM card, while the USI at the time of registration and at the time of reading are registered.
By making the phonebook data readable from the telephone by matching the type of the M card, it is possible to prevent another person from seeing your phonebook data stored in the telephone.

The above description of the operation has been made in the case of telephone directory data. However, the same operation can be applied to the case of received electronic mail, downloaded information (music, pictures, etc.), or other personal information such as voice memos. As reading, they can be prevented from being seen and heard by others.

Further, the association with the type of the USIM card can also be applied to the case of setting the telephone itself. The telephone settings include, for example, ring volume and ring tone type, call volume, key operation confirmation sound ON / OFF, and alarm ON / OFF.
There are many items to be set such as OFF, backlight color, and the like. That is, the setting of the telephone itself is performed in association with the type of the USIM card inserted in the telephone.
Thereafter, when a USIM card is inserted into the phone, the settings of the phone itself are automatically set to the settings associated with the type of the USIM card.

In this way, once the setting of the telephone itself is set to the desired state once for each USIM card (user), the setting of the telephone itself is changed even if the user (USIM card) changes thereafter. Each card is automatically set to a desired state, improving usability.

Although the above-described embodiment is a case where the present invention is applied to a next-generation IMT2000 standard mobile phone, the present invention can be applied to all mobile phones having the same operation method.
