        Hello @anvup1

        Searching through the SIM7020G AT command document the command AT+CCINFO is not listed. I don't think that command exists for SIM7020G.

        For most commands you can check if they are supported by adding =?. E.g. AT+CCINFO=?. Does that actually return OK?

        Thanks
