MOBILE COMMUNICATION TERMINAL AND INTERNATIONAL ROAMING METHOD THEREOF

摘要

Enclosed are a mobile communication terminal and an international roaming method thereof. The international roaming method includes selecting a visiting country to be internationally roamed when international roaming is requested, detecting a radio communication program corresponding to the selected visiting country, making connection to an external program server to request the radio communication program corresponding to the selected visiting country when the radio communication program does not exist, and downloading the corresponding radio communication program from the program server to install the downloaded radio communication program. In the mobile communication terminal and the international roaming method thereof, no matter which radio communication method is used in a region visitied by a user, a radio communication program is newly installed in accordance with the radio communication method of the region so that the mobile communication terminal is reconstituted to perform communication. Therefore, the convenience of the use of the international roaming is remarkably improved.
