I know a lot of you have been struggling out there with your LTE speeds I am no different. It is honestly quite an outrage but here's what I have done and while it's not perfect it is improvement. Don't get me wrong, this fight is not over. I need fast LTE and am paying good money for it. But anyway here are some tips u can try 1) re-insert sim 2) try turning phone off and on 3) try resetting network settings 4) try restoring 5) tell AT&T to reset on their end 6) try another sim 7) make sure safari is noticeably slower at loading pages than in an area where you are getting faster speeds. Don't just go off of speed test. Ultimately, change the darn carrier. It's your money. It's your Internet.
