I think we are talking about the same thing. Or I don't understand.
My device ($MODEM) is always cdc-wdm0. I have a python script
that creates multiple profiles that are identical apart from the
[gsm] block that has different values for sim-operator-id, apn
(and optional username, password and network-id).
I tried the multi-setup stuff, and it is much easier than I thought.
So now I have 7 mobileXXXX profiles and NM is smart enough
to get the correct one and connect on startup, without even needing
nmcli device connect $MODEM
$ nmcli connection
NAME UUID TYPE DEVICE
eth0 7f79871d-15ff-446a-b1c3-5978c81c176b ethernet eth0
eth1 5317eb97-1514-4852-b120-ab4fa9173350 ethernet eth1
mobile20404 ef48d247-00df-433a-bf6a-97ad54e3b757 gsm cdc-wdm0

Wired connection 1 d82449b5-69e2-33c3-944d-c132881f9052 ethernet --
So... Now I just need a way to get the connection name. Is there a
better way than
nmcli c | awk '/cdc-wdm0/ {print $1}'
?
And I managed to make a case when none of the profiles connects (set
gsm.network-id to a provider that isn't in range).
Then it doesn't activate any profile, and it seems like there is no
hope to start the modem.
This is a feature our customers need, that instead of connecting to
the IMSI of the sim card (like 21407), we prefer to roam with operator
12345.
If that fails, fall back on normal roaming. Is that doable? Am I using
gsm.network-id wrong?
