Hello I am trying to find out if it's possible to turn off the 3G radio and not the LTE radio because at my desk my phone automatically switches over to 3G even though I get an LTE signal of about one or two bars which are good enough to have a perfect connection. If I walk to one end of the room I get four bars of LTE but then when I go back to my desk it slowly drops until I have one or two bars at my desk which is still a good enough signal. I don't know if there's a way I can manually enter the network profile for the 3G to disable it or I might have to jailbreak the phone or it's just not possible.
