Here is a helpful guide in case you ever need to quickly check a command for your Simvalley GT-170 or GT-280 GPS Tracker. A quick tip to help you remember commands is to remember the 2-3 digit numbers, since the format and password stay the same for each command.
For smartphone users, a fast way to send commands is to copy and paste previous commands that you used by scrolling up on your SMS dialog.
