phone switches from LTE to 3G as soon as calling someone and stays on 3G, why?
My phone (iphone2s) switches from LTE to 3G as soon as I start calling someone and stays on 3G. The only i have figured is to go to setting -> cellular -> cellular data option ->Voice and Data and then switch from LTE to 3G and then from 3G to LTE again. This is weird.
