Hi, I think you would create each profile only once. Afterwards, you should be able to nmcli device connect $MODEM and then (depending on the SIM), only one of the profiles is a suitable candidate to activate. You can set properties in the profile that tie to the operator, can't you? The only problem is that you have a larger number of profiles, and that you need to create them (once). > > > Note there is merge-request [1].
