First Claim
1. A mobile terminal for providing mobile service subscribers with a mobile service, comprising:
- a country code storage unit for coupling each mobile communication network ID received from each of a plurality of mobile communication network MSCs (Mobile Switching Centers) providing a mobile communication network service for every service area with a country code of a prescribed country in which the mobile communication network is located, and for storing and managing the coupling result of the mobile communication network ID and the country code;
a subscriber information storage unit for storing and managing mobile service registration information and mobile service usage history information of the mobile service subscriber;
a phone number storage unit for storing and managing phone number information; and
a controller for detecting a mobile communication network ID of a current PLMN (Public Land Mobile Network) service, retrieving mobile service usage history information from the subscriber information storage unit upon receiving either a phone number storage command or a phone number search command, determining whether a roaming operation of the mobile terminal is executed on the basis of the mobile communication network ID of the current PLMN service and the mobile service usage history information, and executing a phone number storage command or a phone number search command using both a received entry phone number and a detected country code.

Abstract
A mobile terminal for providing a mobile service and a method for storing and finding a phone number using the mobile terminal. The mobile terminal stores and manages country code information, a mobile service subscriber'"'"'s registration information, and mobile service usage history information; automatically generates a country code of a country where the mobile terminal is located using the mobile service subscriber'"'"'s registration information and mobile service usage history information; and executes a phone number storage command or a phone number search command using the country code. Where an international roaming service is executed by a user'"'"'s moving from one country to another country, the mobile terminal can automatically generate a country code or store an arbitrary phone number. Thus, there is no need for mobile service users to manually enter a country code in their mobile terminal when roaming service is executed.
