Abstract: A system for monitoring device geolocations may enable a mobile device to operate effectively as the device moves across various coverage areas. The system may include a server that receives geolocation data from a mobile device and modifies one or more service plans associated with the device based on the geolocation data. The mobile device may include application software for communicating with the server. The system may also include an administration application that notifies an administrator when a change in a device's geolocation may trigger an action item. The administrator may act on the action item, for example, by modifying one or more service plans associated with the device to enable or disable certain account for the change in the device's location.
