My iPhone 5 on the UK carrier EE keeps on losing its signal and going to "No Service" in areas with very good signal (on my iPhone 4 and OH's 4S). If I turn on airplane mode, and then turn it off again, I connect up to the network again with full signal. The connection is then fine until I walk, or drive to a new location, and when I take my phone out of my pocket, it has No Service again. I love my iPhone 5, but this problem is driving me mad! Has anyone else had this issue? A lot of people are talking about this online, but I can't seem to find anyone that has actually come up with a solution!
