Description
On a new T450s, installed Fedora 23, and have:

This is my first time attempting an LTE card, so I might have something configured wrong, I just want to give my system state and see if there is any advice, or detect a potential bug.
This is a fresh install with:
ModemManager 1.4.10-2.fc23
I try and enable, then add an LTE profile for ATT on my machine (with my ATT SIM), however that profile never seems to hold. Looking at the systemd ModemManager process I see:

Where it appears I'm trying to add an ATT LTE account over and over.
