I can't get my TTGO SIM7000G board to connect to a cellular network. I'm using a SIM that works with other boards so I'm sure that is OK.
Using AT+CSQ from the USB port responds with 20,99. I've never seen 20 before on a SIM7000G so perhaps the modem is faulty?

The signal value of 20 is very normal. In my case, it is about 19~23.
