Loosing signal outside of city center.
I have a Iphone 4S that looses all the signal outside of city center. At home i have full 5 dots signal with 3G.
But a 5-10 min drive outside of the city center i only get 1 dot, but with 3G. Calling does not work.
If turning of the 3G, i will loose all signal.
Driving back home and i will have full signal again. calling and stuff works again. Tried upgrading to newest IOS. Restarting many times, turning on 3G on and off. Turning to airplane mode on/ off.... Nothing do work when the signal is lost.
