This is my problem with AT&T. Incredibly slow speeds on LTE. I'm in N Fort Worth. Other areas are not as bad but also not as good as I've experienced in the past. Time to get this fixed AT&T!!
That's normal for AT&T for the last year or so all over the western US.
Their network is woefully overloaded and I doubt they'll be able to fix it for years. But they're an oligopoly and have no real incentive to fix anything quickly.
Everybody and their mom watching videos on their phones and tablets was an easily foreseeable problem, and they probably knew it was coming, but again, as an oligopoly, had no reason to care.
