SMS commands

Every SMS command sent to device must have a generated signature at the end of the message. Signature depends on entire SMS text, IMEI, key and encryption algorithms. Therefore, SMS must be sent from Wialon or other system which has programed signature generation. Signature is designed to prevent device control by third parties. SMS could be sent from any number.

For the list of SMS commands for SDK devices, check here.

These are the commands that can be sent with via SMS text that will allow to get the wanted information or changes.
Every SMS command should start with the bestpassword as it allows to skip the process of generating a signature.
