SMS over GPRS

SMS over GPRS means that all standard SMS commands text can be sent to device via GPRS in Codec12 format.

If you are not able to receive/send SMS commands (e.g. SMS's are disabled for your SIM card), you can use GPRS commands. GPRS commands use Codec12 and require a direct connection with a server.

SMS over USB

If you cannot send GPRS commands (due to: SIM plan, Codec12, direct server connection, ...) to a target device, you may try connecting the target device to a PC via USB to save logs of the device. While log is being recorded, you should send command
@sms_run:lvcangetinfo

This will print out the information on the CAN adapter in terminal. If possible, itereate the command several times while logging, to make sure that an answer is received. The log is now ready to be analyzed.
