In one aspect, a method of operating a mobile transceiver comprising a processor, a memory, a satellite receiver, and at least one wireless transceiver is provided. The method comprises activating a wireless transceiver associated with a last used wireless service from a low power mode, searching for a wireless signal for the last used wireless service, and selecting an alternate wireless service when the last used wireless service is not available. Different approaches for selecting the alternate wireless service are provided. ## Claims ### Claim 1 A method of operating a mobile transceiver, comprising: activating a wireless transceiver for use with a last used wireless service from a plurality of a wireless services supported by the mobile transceiver in response to waking up the wireless transceiver from a low power mode; searching for a wireless signal of the last used wireless service; when the last wireless service is available, accessing the last used wireless service; and when the last used wireless service is not available, selecting an alternate wireless service from a plurality of wireless services, accessing the alternate wireless service, and updating a last used wireless service in memory in response to accessing the alternate wireless service. ### Claim 2 (depends on 1) The method of claim 1, wherein the plurality of wireless services supported by the mobile transceiver comprises wireless access technologies. ### Claim 3 (depends on 1) The method of claim 1, wherein the plurality of wireless services supported by the mobile transceiver comprise two or more WWAN wireless services. ### Claim 4 (depends on 1) The method of claim 1, wherein the plurality of wireless services supported by the mobile transceiver further comprises WLAN wireless service. ### Claim 5 (depends on 1) The method of claim 1, further comprising: when the last used wireless service is not available, determining via a satellite receiver a location of the mobile transceiver; wherein the alternate wireless service is selected in accordance with stored information identifying which of the plurality of wireless services may be available at the determined location. ### Claim 6 (depends on 1) The method of claim 1, wherein the alternate wireless service is selected from the plurality of wireless services in accordance with one or more selection parameters stored in memory and the determined location. ### Claim 7 (depends on 1) The method of claim 1, further comprising, before determining the location of the mobile transceiver, activating the satellite receiver from a low power mode. ### Claim 8 (depends on 1) The method of claim 1, further comprising: storing the determined location and a time associated with the determined location in the data log stored in the memory; sensing, via one or more sensors, an environment of the mobile transceiver; and storing sensor data obtained via the sensors and a time at which the sensor data was obtained in the data log stored in the memory. ### Claim 9 (depends on 1) The method of claim 1, further comprising: switching to an alternate wireless service specified by a switch command when a switch command is received from an asset tracking service. ### Claim 10 (depends on 1) The method of claim 1, wherein the alternate wireless service is selected from a plurality of wireless services in accordance with one or more selection parameters stored in memory. ### Claim 11 (depends on 1) The method of claim 1, further comprising searching for a wireless signal for the alternate wireless service, wherein the alternate wireless service is accessed when the alternate wireless service is available. ### Claim 12 (depends on 1) The method of claim 1, further comprising: when no wireless service is available, performing a data logging cycle via one or both of a satellite receiver and a plurality of environmental sensors, and initiating a low power mode for the satellite receiver and/or the plurality of environmental sensors after completion of the data logging cycle. ### Claim 13 (depends on 1) The method of claim 1, further comprising: when no wireless service is available, initiating a low power mode for the wireless transceiver. ### Claim 14 (depends on 1) The method of claim 1, further comprising: initiating a low power mode for the wireless transceiver, after sending at least a portion of the data log to an asset tracking service. ### Claim 15 A mobile transceiver, comprising: a processor; a memory coupled to the processor; a satellite receiver coupled to the processor; and a wireless transceiver coupled to the processor; wherein the processor is configured for: activating a wireless transceiver for use with a last used wireless service in a plurality of a wireless services supported by the mobile transceiver in response to waking up the wireless transceiver from a low power mode; causing the wireless transceiver to search for a wireless signal of the last used wireless service; when the last wireless service is available, accessing the last used wireless service; and when the last used wireless service is not available, selecting an alternate wireless service from a plurality of wireless services, accessing the alternate wireless service, and updating a last used wireless service in memory in response to accessing the alternate wireless service. ### Claim 16 (depends on 15) The mobile transceiver of claim 15, wherein the plurality of wireless services supported by the mobile transceiver comprises wireless access technologies. ### Claim 17 (depends on 15) The mobile transceiver of claim 15, wherein the plurality of wireless services supported by the mobile transceiver comprise two or more WWAN wireless services. ### Claim 18 (depends on 15) The mobile transceiver of claim 15, wherein the plurality of wireless services supported by the mobile transceiver further comprises WLAN wireless service. ### Claim 19 (depends on 15) The mobile transceiver of claim 15, wherein the processor is further configured for: when the last used wireless service is not available, determining via a satellite receiver a location of the mobile transceiver; wherein the alternate wireless service is selected from the plurality of wireless services in accordance with the determined location. ### Claim 20 A non-transitory machine readable medium having tangibly stored thereon executable instructions that, when executed by a processor of a mobile transceiver, the mobile transceiver comprising a processor, a memory, a satellite receiver, and a wireless transceiver, cause the processor to: activating a wireless transceiver for use with a last used wireless service in a plurality of a wireless services supported by the mobile transceiver in response to waking up the wireless transceiver from a low power mode; causing the wireless transceiver to search for a wireless signal of the last used wireless service; when the last wireless service is available, accessing the last used wireless service; and when the last used wireless service is not available, selecting an alternate wireless service from a plurality of wireless services, accessing the alternate wireless service, and updating a last used wireless service in memory in response to accessing the alternate wireless service.
