      I am trying to connect a Quectel BG96. Every time after configuring

      AT+COPS=1,2,"20416",9

      It says

      CME Error: 13

      Also a simple command to retrieve the IMSI AT+CIMI gives an error then.

      When I reset the modem and use AT+CIMI again, it works and returns the IMSI. However, after trying to configure the COPS again, the error comes back…

      Any ideas?
