Got my iPhone 5 this morning just before I had to go into work. When I got to work and all was up and running, I was only getting 4G speeds (not LTE). My building is notorious for being a blackhole for service, so I paid little mind. Well, on my way home, I noticed I had 4G all the way home. I'm in the Dallas suburbs, which is highly saturated with LTE. This prompted a call to AT&T. First lady I spoke with tried to tell me that there were no LTE coverage in my area... really? The map you have says different. She came back and said I had. She wanted to reset my network settings, but since I was on the phone, I had to hang up... "call back in 2 minutes" I said. 10 minutes later, no call. Call back in. Finally got someone that actually knew what was going on. I was on another line at this stage... he done some resets, rebooted my phone... still 4G. He said "hold on a second", a few seconds later, as he said "Ok...", LTE appeared!! He said he had to "refresh my registration on the network" Getting decent LTE speeds in my apartment, even though it was also a blackhole for service. Anyway, long story short... if you're having LTE issues where you should be getting LTE coverage, give them a call to reset everything. If this wasn't resolved, it would have been a dealbreaker for someone who has been with AT&T for about 13-14 years.
