Abstract At switch-on or when recovering from lack of coverage, a UE determines first frequency bands corresponding to an initial MCC of a country in which the UE currently is located (402). The frequency bands include a first set of frequency bands associated with a network carrier to which the UE is subscribed and a second set of frequency bands not associated with the network carrier (404). The UE scans the first set of frequency bands (406). In response to detecting a new MCC and determining that no service is available within the first set of frequency bands (408), the UE scans a third set of frequency bands preferred by the UE within a second plurality of frequency bands corresponding to the new MCC (410). In response to determining that no service is available within the third set of frequency bands, the UE scans the second set of frequency bands (412).
