Warning

The exact command to create a new connection depends on the 3G card model used and the sim card provider. Different cards will use different interfaces (ifname) and different sim providers will use different apn, user an password.

To check the port to be used execute the command 'sudo mmcli -m 0' and check the System / Primary Port
