We own a few SmartSense 3G gateways (TM-CELL400-Z-3G) fka TempAlert, but just received an email today these will be going offline soon, due to the fact that Verizon is shutting down 3G coverage.
I can change the SIM-card in these devices to use a different network, but would need to update the APN accordingly. How can we update these settings?
