SIM Card Connectivity Issues on the fleet 790
When a SIM card is inserted into the SIM card slot, it is necessary to reboot the modem before it can be registered on a cellular network. The easiest way to reboot the modem is to completely power off the device and power it back on when not connected to power.
Cellular data connectivity will only become possible if the device is provisioned with the correct APN settings. The APN settings are automatically provisioned by the device, but in some situations, the APN may need to be provisioned manually. Upon installation of a new SIM, the device APN settings should be verified and can be updated directly on the device via the device APN setting or via an API provided by the Fleet SDK.
