Technical Examples
  1. Methods and apparatus for selecting a cellular network to provide one or more communication services for a mobile communication device are disclosed. A scanning operation is performed by the mobile device to identify a plurality of cellular networks that support a voice communication service in a geographic coverage area. The mobile device then identifies which of the cellular networks makes a data communication service available to it. Advantageously, the mobile device assigns priority to or selects a cellular network that makes the data communication service available over a network that fails to make the data communication service available, and may register with that network. The data communication service may include, as examples, an e-mail communication service or an Internet access service. Preferably, the cellular network operates in accordance with GSM (Global System for Mobile) and GPRS (Generalized Packet Radio Service).
