Abstract:
A user device determines whether a modem specifies at least one network present at a current geographical location of the user device. When the modem does not specify any present networks, the user device identifies one of the present networks that is available to provide a roaming service to the user device, and adds the identified network to a list of preferred networks in the modem.
