Andrei,
I’m using an Orange Pi 2G IoT device (http://www.orangepi.org/OrangePi2GIOT/). I believe I’ve tried that as well but still no luck. Was wondering if anyone else had a series of AT commands that were successful. I’ve tried several things and its like the SIM won’t register with the network. Starting to wonder if the SIM or board is bad.
ryanHologram had suggested in another post (Device Not Registering/No Network Available) running the following commands and posting their output so I’ll give that a shot.
