1. A method for determining the availability of a user of a mobile communications device on a network, comprising:

  • collecting, from a plurality of mobile communications devices associated with a coverage service and one or more carriers, a plurality of data sets;

    determining at least one predefined service boundary in respect of each of the one or more carriers using the plurality of data sets, the predefined service boundary defining a locus of locations where a change in service is expected to occur;

    after determining at least one predefined service boundary, generating service coverage data defining a geographic location of at least a segment of the at least one predefined service boundary for a predetermined geographic region;

    providing service coverage data comprising at least a segment of a predefined service boundary between different areas of service provided by different service providers;

    determining, using tracking data for the mobile communications device, when the mobile communications device is likely to exit the predetermined geographic region;

    transmitting to the mobile communications device further service coverage data defining the geographic location of at least a segment of the predefined service boundary for an adjacent predetermined geographic region that the mobile communications device is expected to enter; and

    issuing a notification of a change in service associated with crossing the predefined service boundary from one area serviced by one service provider to a different area serviced by another service provider.
