Abstract
Official abstract text for this publication.
A computerized method for subscribing an international roaming plan for a communication device, the communication device includes an electronic map. At least one border checkpoint of a predetermined country can be determined on the electronic map. A distance between a current location of the communication device and the location of the at least one border checkpoint is calculated. When the calculated distance is less than a predetermined distance and the current location of the communication device is within the home country, a user may be prompted to select whether to subscribe to an international roaming plan for a particular period of time. A preset message is sent to a predetermined service terminal provided by a telecommunication company to subscribe to the international roaming plan for the communication device when the user makes a selection to subscribe to the international roaming plan for the communication device.
