If the verification user additional information inputted as a result of the determination in step S470 matches the user additional information previously stored in the USIM card 240, the flow proceeds to step S480. On the other hand, if the input user additional information does not match the user additional information previously stored in the USIM card 240, the flow proceeds to step S475.

In step S475, it is determined whether the user additional information does not match a predetermined number of times. If the user additional information does not match, the memory unit 220 of the portable terminal 100 is accessed to check the remaining number of matching checks, and the user additional information is determined to be matched to the extent possible.

For example, when the predetermined number of times is set to five times, and if the number of times that the user additional information does not match is less than five times, the process returns to step S460 and the user additional information is input again. On the other hand, when the number of times that the additional user information does not match is more than five times to proceed to the emergency mode. In this case, the emergency mode is a state in which a general call cannot be made but only an emergency call can be made. In the above example, a certain number of times has been described as five times, but this may be variously changed within the scope of the present invention.
