MBIM modems may not have their own DHCP built-in server, so
ModemManager always defaults to STATIC IP configuration. If you see
the Bearer object contents once you're connected, you'll get the IP
details you have to use in the network interface:

$ mmcli -b 0

ModemManager doesn't set those; the user (or another app) would set
those. E.g. when used alongside NetworkManager, it's NM the one
setting the IP settings in the iface.
