This is a new 3G tracker which uses a completely different command set but still has a similar feature set to other devices.
The command set is case insensitive but I have chosen to use upper case for the commands, as per the manual, to make it clearer.
The accompanying manual for the tracker is available here… TK119-W 3G Manual
It seems to be a vehicle oriented tracker, taking a wide voltage input range (6-36V) so it can be powered directly on pretty much any vehicle. It also has a relay control so the fuel pump or some other cutout can be used to immobilise the vehicle remotely.
Unlike the majority of trackers this device does not use a password, relying instead on the caller ID to authorise. I’m not sure if this is a security risk or not at this stage as I’ve not had a unit myself to experiment with.
