1. A method of scanning frequencies for registration onto a wireless service provider by a wireless device comprising:
- receiving and storing itinerary information on the wireless device, the itinerary information including a plurality of locations of the wireless device at a future date and time outside of the wireless device'"'"'s home network;
requesting a plurality of predefined priority sequences of frequencies based on the itinerary information;
receiving and storing the plurality of predefined priority sequences of frequencies on the wireless device;
determining on the wireless device a current expected location of the wireless device in real-time based on the itinerary information;
determining on the wireless device a priority sequence to be scanned from the plurality of stored priority sequences based on the current expected location; and
scanning frequencies according to the priority sequence for the current expected location.

Abstract
A method of scanning frequencies for registration onto a wireless service provider by a wireless device is provided. The inventive method comprises predefining a priority sequence of frequencies in association with each of a plurality of locations. Itinerary information is received and a current expected location of the device in real-time based is determined based on the itinerary information. The device then scans frequencies according to any priority sequence predefined for the current expected location.
