Trying to figure what Protocol is this tracking device using.

Hi, I am doing some tests with a TKStar TK905 5G.
I can see that the structure of the commands are like this:

[SG*9059075136*0009*LK,0,70]

I was wondering if anyone know what GPRS protocol it uses or if anyone has the proper documentation for it.

I would very much appreciate it, thank you in advanced!

Probably one of these:

Look like Watch protocol port 5093

Thanks you both, I've found it there, it was indeed Watch protocol, I really appreciate it.
