Abstract
A method of selecting a cellular network entails determining a current location using a Global Navigation Satellite System (GNSS) receiver in a mobile device, prioritizing bands based on the current location to create a set of prioritized bands, and searching the set of prioritized bands for the cellular network. This method expedites selection of the cellular network when a mobile device is powered on or when its cellular radiofrequency transceiver is activated.
