I think what confused me is that without the ModemManager i.e. using
just cgact=1,1 to manually connect, i suddenly got an ip address
assigned to the network interface provided by the modem. I thought it
was NetworkManager running its dhcp client on that interface after
getting a dhcp discover ? from the modem ? (i'm not too sure about how
dhcp goes about its business)
Anyway i have now tried to use Network Manager to setup and connect but
now am getting the following message:
modem-broadband[ttyUSB0]: failed to connect 'meig': Connection requested
both IPv4 and IPv6 but dual-stack addressing is unsupported by the modem.
and disabling ipv6 I get:
failed to connect 'meig': Connection requested IPv4 but IPv4 is
unsupported by the modem.
Any idea where to start debugging that ?

I see where you are going with this. It seems I expected more of the
interaction between the ModemManager and Network Manager . To answer your
question, no I have only used mmcli. Let me try the process with nmcli.
:) NM only processes the connections that have been started via NM.
There's a fundamental reason for that, which is that all the
network-specific routing is done at NM level, MM knows nothing about
it. In order for NM to know how to route traffic to through the LTE
connection, it needs to use its own connection settings.
