Sinotrack ST-901 can only respond to phone call

Hao6 years ago

Hey guys. I'm testing Sinotrack ST-901 but have some trouble with it.

My service provider is Google Fi. I only have nano SIM card so I manage to insert it with 3 pins touching the SIM card. I can see that the yellow LED is ON all the time which means GSM should be working. I tried to called the number and can receive a SMS from it reporting current location and speed. However, it doesn't responding to any SMS commands now. No RCONF. No RESTART.

Does anybody know how to fix that?

Somehow, I randomly received two messages of RCONF response! But it disappeared after that. No idea what's going in.
