I live in Miami, Florida. There is supposed to be excellent LTE coverage for miles around and I haven't been able to,get my phone to connect to it by way of seeing the LTE symbol on my phone. It is strictly 4G all of the time. My DL speeds range from 1.5Mb to 9.5Mb and UL speeds are around 1.3Mb. Nowhere near attainable speeds for my area as I have seen posts confirming 20up/10down. I called AT&T support about this and spent a good half hour to forty five minutes with a main CS rep, then a tech support specialist. In the end, the specialist told me that I am actually connected to the LTE network but my phone just says 4G and Apple would be issuing an update "soon" to fix the situation. I asked the specialist why my speeds weren't near real LTE expectations and he copped out to "network congestion". I don't believe the runaround about the update from Apple. Has anyone had a similar response from AT&T? My next step is to,talk to Apple Support and see if maybe it's a hardware issue with my phone in particular.
