The issue persists when I restore the backup. If I do not restore it (ie if I ser it up as a new phone), then it connects to LTE. I already know that it is some kind of setting that is being restored with the backup that is causing the issue to persist, as I indicated in my original post. I would like to find a solution that allows me to isolate whatever setting in the backup is causing the issue and address that rather than having to wipe all the data from my phone. Based on my issue, this is a known issue, and there should be a solution that doesn't require me to delete everything.
