I live 20 miles north of Detroit and still only able to get 3g while my wifes t-bolt has 4g. Is it the weak radio in my phone? I already pulled battery.
You could try to power cycle the device. I have a problem where I lose data when switching the network modes from LTE to CDMA. I have to cycle the device to have to pick back up(I'm guessing it's an authentication error).
