I know that only AT+CSTT=“apn”,“pass”, AT+CIICR and AT+CIFSR where needed but I’ve used the other commands to show more usefull(?) info.

Seems like the SIM is not getting network connection? Are you sure its registered to the network? Ring the module SIM card and check to confirm. Its a 2G device, hope your network supports 2G
