When manually connected through mmcli, you need to manually configure
the WWAN once connected. This is, once your --simple-connect call
succeeds, you then need to ifup and setup the WWAN.

As Yegor suggests, you can just run a DHCP client on the interface
once --simple-connect succeeds, and the DHCP server built-in the modem
will get you the WWAN setup with the correct details.

But, if you also use NetworkManager, you shouldn't need to run mmcli
--simple-connect, and instead you'll need to create a mobile broadband
setting (doesn't nmcli now allow to do this?) and get that connection
activated in NM. NM will then take care of the MM connection and WWAN
setup automatically.
