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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The method of claim 1, further comprising: resetting the cellular transceiver using the second SIM card; searching, via the cellular transceiver, for available wireless services associated with the second SIM card; and switching from the second SIM card to a further SIM card in the plurality of SIM cards when a wireless service for the second SIM card is not available. ### Claim 3 (depends on 1) The method of claim 1, wherein the first SIM card is determined in accordance with a location of the mobile transceiver. ### Claim 4 (depends on 1) The method of claim 1, wherein the first SIM card is determined in accordance with a country in which the mobile transceiver is located. ### Claim 5 (depends on 1) The method of claim 1, wherein the mobile transceiver is waken up from the low power mode in response to a wakeup event, wherein the first SIM card is determined in accordance with the wakeup event. ### Claim 6 (depends on 1) The method of claim 1, wherein selecting the first SIM card from the plurality of SIM cards comprises: determining from a memory of the mobile transceiver a pre-selected SIM card from the plurality of SIM cards; and selecting the pre-selected SIM card from the plurality of SIM cards. ### Claim 7 (depends on 6) The method of claim 6, wherein the first SIM card is pre-selected in accordance with the wakeup event. ### Claim 8 (depends on 6) The method of claim 6, wherein the pre-selected SIM card is a last used SIM card. ### Claim 9 (depends on 1) The method of claim 1, wherein the wakeup event is a time-based alarm. ### Claim 10 (depends on 1) The method of claim 1, wherein selecting the first SIM card from the plurality of SIM cards comprises: determining a location of the mobile transceiver using a satellite receiver; and selecting the SIM card from the plurality of SIM cards in accordance with characteristics of the first SIM card and the determined location of the mobile transceiver. ### Claim 11 (depends on 10) The method of claim 10, wherein the wakeup event is a sensor-based alarm. ### Claim 12 (depends on 1) The method of claim 1, further comprising: when each SIM in the plurality of SIM cards has been attempted and no wireless service is available, initiating a low power mode for the mobile transceiver. ### Claim 13 (depends on 1) The method of claim 1, wherein the plurality of SIM cards comprises virtual SIM cards. ### Claim 14 A mobile transceiver, comprising: a processor; a memory coupled to the processor, the memory having stored thereon executable instructions for execution by the processor; a cellular transceiver coupled to the processor; a plurality of subscriber identity module (SIM) cards coupled to the processor; wherein the executable instructions, when executed by the processor of the mobile transceiver, cause the mobile transceiver to: wake up the mobile transceiver from a low power mode; select a first SIM card from a plurality of SIM cards; activate a cellular transceiver using the first SIM card; search, via the cellular transceiver, for available wireless services associated with the first SIM card; and switch 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. ### Claim 15 (depends on 14) The mobile transceiver of claim 14, wherein the executable instructions, when executed by the processor, cause the mobile transceiver to: reset the cellular transceiver using the second SIM card; search, via the cellular transceiver, for available wireless services associated with the second SIM card; and switch from the second SIM card to a further SIM card in the plurality of SIM cards when a wireless service for the second SIM card is not available. ### Claim 16 (depends on 14) The mobile transceiver of claim 14, wherein the first SIM card is determined in accordance with a location of the mobile transceiver. ### Claim 17 (depends on 14) The mobile transceiver of claim 14, wherein the first SIM card is determined in accordance with a country in which the mobile transceiver is located. ### Claim 18 (depends on 14) The mobile transceiver of claim 14, wherein the mobile transceiver is waken up from the low power mode in response to a wakeup event, wherein the first SIM card is determined in accordance with the wakeup event. ### Claim 19 (depends on 14) The mobile transceiver of claim 14, wherein the executable instructions to select the first SIM card from the plurality of SIM cards, when executed by the processor, cause the mobile transceiver to: determine from a memory of the mobile transceiver a pre-selected SIM card from the plurality of SIM cards; and select the pre-selected SIM card from the plurality of SIM cards. ### Claim 20 A non-transitory machine readable medium having tangibly stored thereon executable instructions for execution by a processor of a mobile transceiver, the mobile transceiver comprising a cellular transceiver and a plurality of first subscriber identity module (SIM) cards coupled to the processor, wherein the executable instructions, when executed by the processor, cause the mobile transceiver, to: wake up the mobile transceiver from a low power mode; select a first SIM card from a plurality of SIM cards; activate a cellular transceiver using the first SIM card; search, via the cellular transceiver, for available wireless services associated with the first SIM card; and switch 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.
