As a side comment, if automatic connection is ever implemented, it
should probably
consider whether the modem is roaming or not, to avoid excessive charges.

I've given this a stab in lr/gsm-default-apn branch. Please take a
look:
https://gitlab.freedesktop.org/NetworkManager/NetworkManager/merge_requests/98
Connecting the modem is not entirely automatic; you still need to
connect a device ("nmcli d connect ttyUSB666").
For the device to connect automatically new_default_connection() would
need to be implemented for NMDeviceModem. That would probably involve
factoring out the logic from src/devices/nm-device-ethernet.c's
new_default_connection().
Elsewhere in the thread Aleksander argued that it would be somewhat
risky, but it has been also argued that phones tend to do that and the
world hasn't imploded yet. I tend to think it is in fact a good policy
for most installations and distributors or users who would object this
could do so by dropping a snippet with no-auto-default= setting into
conf.d/.
For now the biggest shortcoming of the branch is that the code is
probably not very beautiful and could use some review or polishing. If
you'd like to pick it up and maybe add the autoconnect functionality,
you're welcome to do so. Feedback is also welcome.

I'm not sure if this fear is based on known real usecases or it should really be obsoleted by now, though, especially since all LTE devices have "some sort of active connection" as soon as they're registered to the network. Otherwise, the worst thing that could happen if using a wrong APN is that the modem doesn't connect with the automatic settings, which, well, that shouldn't be a big issue. Users that require special APN settings will anyway need to insert them manually. I really have mixed feelings, so I've always suggested that automagic APN setup to be optional.

Why so? I’d see such a thing as a lovely features, and you pretty much loose the benefit of it being default if you have to find out you need to activate. On the other hand it would be so neat to put a sim card in a computer that happens to have a free-software supported wwan card and get stuff just working! I mean, it’s what most mobile phones do, right? Could it at least be done so more user-friendly distribution (such as Debian, by opposition with, say, Parabola, Gentoo, etc.) makes this a default, through configuration files (and not only GUI), so uncaring user would benefit it neitherless? ___ networkmanager-list mailing list networkmanager-list@gnome.org https://mail.gnome.org/mailman/listinfo/networkmanager-list
Re: automatic APN selection
Hey, just so you know this basically exists. You just need to create a connection profiles with the correct "sim-id" "apn" pairs. Some users, myself included, wouldn't want this to be automatic because we use private APNs, but you could easily put together an optional package of connection files that accomplishes this.

Re: automatic APN selection
Sorry, I meant "sim-operator-id". "sim-id" wouldn't work, as it is unique to each sim card. Alex Ferm PetroPower, LLC. 3003 E. 37th Street N.
