I upgraded back in Oct 25? From 3G to 4G and STILL has not changed? I’m being charged 4G but still on 3G? So can you please help me with this and put through my up grade , thank you.
I have tried what you suggested and also turned iPhone off and on again , the only things I can switch to is either 3G and LTE , there is no 4G ….my phone is the IPhone XR ..I read that LTE is a half way point between 3 and 4G? But still not a solid...
