A method for steering of roaming (SOR) in wireless communication networks includes sending by a mobile equipment (ME) a registration message to a visited public land mobile network (VPLMN). The ME receives a first message from a home public land mobile network (HPLMN) through the VPLMN. The ME determines that the first message has failed a security check. In response to determining that the first message has failed the security check, the ME sends a second message to the VPLMN, the second message including an indication that the first message has failed the security check.

Method and apparatus for multi-SIM selection

A method and mobile transceiver with adaptive monitoring are provided. In accordance with one embodiment, there is provided a method of operating a mobile transceiver, comprising: waking up the mobile transceiver from a low power mode in response to a wakeup event; determining a waypoint in a travel itinerary corresponding to the wakeup event, the travel itinerary defining a number of waypoints including an origin endpoint and destination endpoint; and setting one or more subsequent wakeup events based one or a combination of a time of the wakeup event, sensor data at the time of the wakeup event, and the determined waypoint.

Mobile transceiver with adaptive monitoring and reporting

A mobile transceiver having multiple subscriber identity module (SIM) cards and a method of selection is provided. In accordance with one embodiment, there is provided a method of operating a mobile transceiver, comprising: using a cellular transceiver in association with a first subscriber identity module (SIM) card in a plurality of SIM cards to access a first wireless network; and using the cellular transceiver in association with a second SIM card in the plurality of SIM cards to access a second wireless network in response to a failure to access the first wireless network with the first SIM card.

A mobile transceiver having multiple subscriber identity module (SIM) cards and a method of selection is provided. In accordance with one embodiment, there is provided a method of operating a mobile transceiver, comprising: activate a cellular transceiver using a first subscriber identity module (SIM) card in the plurality of SIM cards; switch from the first SIM card to a second SIM card in the plurality of SIM cards in response to a determination that a wireless service for the first SIM card is not available.

A method and mobile transceiver with adaptive monitoring are provided. In accordance with one embodiment, there is provided a method of operating a mobile transceiver, comprising: waking up the mobile transceiver from a low power mode in response to a wakeup event; determining a waypoint in a travel itinerary corresponding to the wakeup event, the travel itinerary defining a number of waypoints including an origin endpoint and destination endpoint; performing an action associated with the wakeup event; determining a wakeup frequency associated with the determined waypoint; and setting a wakeup frequency of one or more subsequent wakeup events in accordance with the determined wakeup frequency.

A mobile transceiver having multiple subscriber identity module (SIM) cards and a method of selection is provided. In accordance with one embodiment, there is provided a method of operating a mobile transceiver, comprising: waking up the mobile transceiver from a low power mode; selecting a first subscriber identity module (SIM) card from a plurality of SIM cards; activating a cellular transceiver using the first SIM card; searching, via the cellular transceiver, for available wireless services associated with the first SIM card; and switching from the first SIM card to a second SIM card in the plurality of SIM cards when a wireless service for the first SIM card is not available.

Method and apparatus for multi-sim selection

A method of scheduling wakeup events, method of operating a mobile transceiver, and devices configured for same are provided. In one aspect, there is provided a method of scheduling wakeup events for a mobile transceiver, comprising: obtaining a first GNSS data set comprising a plurality of GNSS coordinates, the first GNSS data set defining a route; applying a curve simplification algorithm to generate a second GNSS data set comprising a plurality of GNSS coordinates, wherein the second GNSS data set is a subset of the first GNSS data set; defining one or more alarms as wakeup events to activate the satellite receiver from a low power mode based on the plurality of GNSS coordinates of the second GNSS data, wherein the one or more wakeup events are each defined by an alarm; and applying the one or more alarms.

Method of scheduling wakeup events, method of operating a mobile transceiver, and devices configured for same

A mobile transceiver having multiple subscriber identity module (SIM) cards and a method of selection is provided. In accordance with one embodiment, there is provided a method of operating a mobile transceiver, comprising: activating a cellular transceiver using a first SIM card in a plurality of SIM cards, wherein the first SIM card is a last used SIM card in the plurality of SIM cards; searching, via the cellular transceiver, for available wireless services associated with the first SIM card; and switching from the first SIM card to a second SIM card in the plurality of SIM cards when a wireless service for the first SIM card is not available.

A mobile transceiver having multiple subscriber identity module (SIM) cards and a method of selection is provided. In accordance with one embodiment, there is provided a method of operating a mobile transceiver, comprising: waking up the mobile transceiver from a low power mode in response to a wakeup event; determining whether a SIM card has been pre-selected for a location of the mobile transceiver or the wakeup event; when a SIM card has been pre-selected, selecting the pre-selected SIM card as a first subscriber identity module (SIM) card, activating a cellular transceiver using the first SIM card, and searching, via the cellular transceiver, for available wireless services associated with the first SIM card; and when a wireless service is available, sending at least a portion of a data log to an asset tracking service using the wireless service.
