1. A method in a wireless communication device comprising:
- receiving a first System Identification Number (SID) via a first wireless communication signal from a first wireless carrier operating within communication range of the wireless communication device;
receiving one or more additional SIDs via one or more additional wireless communication signals from one or more additional wireless carriers operating within communication range of the wireless communication device;
determining a signal quality level for each of the first and the additional wireless communication signals received from the first and additional wireless carriers respectively;
determining a preference level for each of the first and additional wireless carriers based on a Preferred Roaming List (PRL); and
selecting one wireless carrier from either the first wireless carrier or the additional wireless carriers based on the signal quality level of each wireless carrier and based further on the preference level for each wireless carrier.
