Looks like ModemManager is crashing somewhere as it's disappearing from the bus all the time. Could you get debug logs? Steps here: http://www.freedesktop.org/wiki/Software/ModemManager/Debugging/ Also, if you could compile MM (from the mm-1-4 branch in git) yourself and get a backtrace while running gdb that would be superb.

Running into a snag. The ModemManager debug log for a couple minutes of trying to enable the LTE connection is 225MB in size. For comparison the NetworkManager log is about 300KB. What do you suggest to do? (In reply to Andrew G. Dunn from comment #3) > Running into a snag.

How come is that big? Can you compress it and share it somehow (email me privately if you cannot put it anywhere online)? -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.

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.
