Hello all, I had a Raspberry Pi running Arch with two USB LTE Modems on two differet Network operators. This was all working perfectly but suddenly crashed mid week. Instead of repairing that old system, I still have it and can go back to it, but I decided that I'd grab a new SD card and install the latest and greatest. This is where the problem is I create my two LTE network connections and sometimes the network manager seems to be attempting to create network connections on the wrong modem. When I pulled one modem I powered up and got an IP Address from one connection but when I couldn't ping anything I had a look in the network manager and it's connected a "Three" operator connection on a "Vodafone" SIM. This used to work perfectly. BTW as both my modems are exactly the same model I can't distinguish them with udev rules.
Only recently, on master there are 3 connection properties to match a gsm-onnection on a device: device-id, sim-id, and sim-operator-id. https://bugzilla.gnome.org/show_bug.cgi?id=756916 http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=dd2f09c8b166cc5f317a5298f01ea161c63895e6 I think that would be a solution for you, but the patches are not backported to nm-1-0 branch.
