I have just moved to a rural area with weak phone signals and my iPhone 5 is struggling to maintain a usable connection indoors. I was wondering if the reception in weak areas was improved with newer iPhones or whether the antennas are of similar performance between phone generations? I am in the UK with O2 and it appears to be the most used provider in my area but I am just on the cusp of a low hill and on the edge of the signal "shadow". That mast is enabled for all services up to 4G (which I don't get on the iPhone 5 of course). At best I get 2 dots of 3G indoors, more often one. At several times of day it drops to EDGE and still only gives me 2 dots. If I go outdoors, the signal improves a little in that I get 3 dots of EDGE and the phone usually polls back to 3G when it notices the change and gives two or three dots of 3G. The construction materials of the building are timber throughout with no stone or particularly brick. What are my options here? Do you think a 7 would have a more sensitive antenna? Am I allowed to ask for a micro-transmitter?
