1. A mobile station for providing a communications link for a machine-to-machine (M2M) application, the mobile station comprising:
- mobile equipment comprising;
a microprocessor module operative to control operation of telemetry of the mobile station based on local sensor information and commands received via a cellular network;
a transceiver, operatively coupled to the microprocessor module, operative to process wireless signals incoming from and outgoing to the cellular network; and
an antenna, associated with the transceiver, that conducts the wireless signals;
a subscriber identity module (SIM); and
a computer program loaded on the subscriber identity module, the computer program comprising a timer that increments time based on detecting transmissions of periodic messages containing location information, wherein the timer is operative to trigger one or more time-based actions responsive to the timer determining that a predetermined amount of time has passed by counting the transmissions of periodic messages and comparing the count to a threshold number that is greater than one, the threshold number equating to the predetermined amount of time according to transmission time interval,wherein the subscriber identity module comprises forbidden public land mobile network data stored in memory of the subscriber identity module and managed by the one or more time-based actions that the timer is operative to trigger.

Abstract
A mobile station connected to a wireless network can comprise a subscriber identity module. The subscriber identity module can maintain a list of networks. The list can comprise forbidden public land mobile network data. Software can manage the forbidden public land mobile network data. For example, an applet transmitted to the subscriber identity module can periodically delete entries from the list and/or reset the subscriber identity module on predefined time intervals or when specified events occur.

6. A mobile station for a machine-to-machine (M2M) application, comprising:
-
a transceiver that is configured to send telemetry data over a cellular network to a gateway; and a subscriber identity module (SIM) comprising instructions for; tracking time from within the subscriber identity module by counting communications that carry location information and that are transmitted periodically over the cellular network; determining if the tracked time has met a threshold by determining if a predetermined number of the communications have been counted, the predetermined number at least two; and if the tracked time has met the threshold, modifying forbidden public land mobile network data stored in memory of the subscriber identity module. - View Dependent Claims (8, 9, 10, 11, 12, 13)
