Today my LTE went out in Waco, TX. I had the 4G icon, my network was LTE14, but I had no connection.
I got on chat and the rep said they were having issues and it should be resolves shortly.
3 hours later I am getting LTE in areas of my home that I did not previously have. Worth the wait. I'm getting about 4000down 4000up in the middle of my home.
