4G LTE Won't Enable on AT&T iPhone 5S?

A few days ago I upgraded my iPhone 4S to the 5S and was pretty excited for some LTE speeds. But all that my phone shows is that I have regular 4G and I have no idea why. I checked the AT&T website for support with no luck. I even checked my account setting for my phone and nothing seems to be wrong. Why am I not getting LTE?

4G and LTE are the same thing.
They say a new standard is coming out soon called LTE-A but the phones will need to be equipped with such a chip.
For now, that's it: 4G = Long Term Evolution

LTE same as 4G

  • Why won't my iPhone connect to LTE when switching from Wi-Fi? The LTE symbol is visible at the top of my phone. However, I still can't access the internet or Siri. This happens when I'm out of Wi-Fi range and trying to switch into LTE. I tried turning on/off the Wi-Fi and Data connection. It seems the only solution is to shut off my phone and turn it back on. However, this is too inconvenient.
  • Why won't LTE work on my iPhone 5s? Just got the iPhone 5s for US Cellular. Data usage is part of my plan. However, when I'm not connected to Wi-Fi, the internet does not work. It says I'm connected to LTE, and I have 4-5 bars of service, yet, it does not work. Any advice or answers as to what is going on and how I can fix it?
  • My LTE won't work on iphone 5? To the right of where it sais AT&T it's empty and I've reset my network settings, taken out the SIM card switch on and off airplane mode and power off my phone. I quit
  • LTE on my new iPhone 5 won't work? I just bought a used iPhone 5 from a friend. He used to have Verizon but he took the SIM card out. I put my SIM card in and my carrier is Straight Talk. Ever since I got my new phone I don't get LTE but the plan I have gets LTE. I've only been receiving 3G and it's really annoying. Please help me figure out why this is and who I need to contact to fix it or if I can fix it myself.
