    This is my second iPhone 5. First one was replaced for this exact problem. You can try to have it replaced and maybe you will have better luck than me. At least with this iPhone 5 it does not happen multiple times a day like the previous one.

    I've had an issue with signal strength flat-line in my house on my iPhone 5 (AT&T) while my wife's 4S (also AT&T) not changing one bit. So far AT&T has logged two incidents on my phone's signal. I don't get many phone calls and use WiFi at home so it's not a huge deal. AT&T is not that solid in my neighborhood anyway plus, outside my house, the signal is fine. Bottom line it seems to me that, in my situation, iPhone 5 is more finicky about signal strength than the 4S.

    I have two iPhone 4's and a 4s that are fine with signal as well.

    I'll just see how it goes for a little longer. It's more annoying than anything. Guess I'll do some comparisons when my Nexus 4 arrives next week hopefully.

    Sorry to bring up an old thread. I'm having tis same issue on my iPhone 5 on VZW.... Anyone find a fix? I'm on my 2nd iPhone 5. I've reset network settings and that fixes the problem for a bit. But then the issue resumes a few days later. The only way t fix it is to turn on airplane more and then back off.

    Anyone find a fix?

    I just turned off international data roaming that fixed my problem.

    Ive had almost 30 4s units and almost all have done this. It's a combo carrier+AppleOS+AppleHardware issue. It's been going on since Oct 2011. There are TONS of reports of this all over the internet now, and so far no firm fix. Some say go back to an old OS where it was known to start, but I have since tried that and updated through, and it has not fixed it.
