    I've noticed a few times now that my phone goes from 4G (AT&T) down to either edge or no signal. I don't live in an LTE area. Then when I'm back in an area with known service, it won't reconnect without toggling the airplane mode. Anyone else seeing this on any other carrier? I think it may be an iOS 6 issue? Hopefully not an issue with the iPhone 5 itself!

    I have a Sprint iPhone 5, and have noticed it kicking off of wifi while in standby... But that's a known issue. Haven't seen it drop 3G but it does drop LTE in standby as well. I don't know of its trying to save power or what - I'm in an LTE area but don't generally leave LTE switched on unless I'm actively using it to conserve battery, but the times I have left it on on accident I've noticed when it'll drop LTE for 3G on occasion.

    Note: I have perfect signal for both 3G and LTE (and WiMAX before) where I live, so it's definitely not a fringe area issue.

    Or possibly the SIM. It can be either of the 3. I would say remove the sim, reboot (hold home and power button until restart) the phone and see if it gets better. You can also reset network settings too in settings. Try those and see what happens.

    My 4S did this more than randomly. Neither iOs6 nor iPhone 5. It's at&t.

    I failed to mention I had an iPhone 4 and this never happened. Only since either iOS 6 or iPhone 5. Not sure which is the culprit.

    I have noticed the same thing. I am with Verizon and saw 30-40mbps speeds on LTE with my android. Since switching to the Five (preordered) I have seen a drop of speed to no better than 12-17mbps at best. I have also noticed that I lose high speed and go down to 1x quite a lot.

    I'm on Verizon & haven't had any issues on my iPhone 5 or my son's 4S running iOS6. I'm in great service area & my signal is always strong for LTE & 3G

    Same here. I like iOS 6 and although it isn't perfect, it is a solid upgrade, in my opinion.

    The signal on my AT&T iPhone 5 is just as good if not slightly better than my old 4S. I haven't noticed any signal loss issue at all since I got it on launch day.

    So I tried resetting the network settings and so far I seem to be holding a signal. Even better, when I go to edge it now goes back to 4G on its own.

    I own the 5, on IOS 6, with Verizon and I too notice 3G dropping to 1x a fair amount in weaker areas. When I am in a legit LTE area the signal stays strong without ever compromising. But in weaker areas I notice my phone will drop to 1x whereas other phones I have had in the past (Nexus and S3) maintained 3G.

    For what it's worth, I decided to try the Lumia 900 instead of the iPhone 5 on a new line of service, (have an iPhone 4s on another line), and I have a similar problem where in a reasonable LTE signal area at home I lose LTE and drop to 4G until the radio is cycled via airplane mode, and then it picks up LTE right away again.

    In fact I was about to give up on the Lumia and replace it with an iPhone 5 until I read this thread. Seems like maybe it's a carrier thing rather than a phone thing?

    Although, I've never noticed this issue with my LTE iPad--seems to always have an LTE signal in the same place where the Lumia 900 drops it.

    I don't seem to have that last step you took..."mobile network settings"

    looks different with the language set to English.
    I guess it is the Network Cell Search option.

    Was traveling today and had the Verizon circle in numerous spots with known 3G coverage. It's frustrating but even more so worrisome because its not likely going to improve. Now I need to figure it out if its bothersome to the point of returning it.

    Well I see I'm digging up an old thread here. But has anyone found a fix to this issue? It seems to be affecting my iPhone 5 as well.

    If it loses 4G signal it seems to not be able to get it back. At work the 4G signal can go in and out as I move around the building. It drops to EDGE, then nothing, back to EDGE. It's like it's cycling through the networks trying to get a signal. It doesn't seem to drain the battery though. There is no LTE at my home yet.

    Unfortunately no. There were some on the apple forums that were saying 6.1 fixes this problem, but I am still having this issue just not as frequently.

    Mine is behaving differently with 6.1 however. On 6.0.2 if it lost 4G it would then jump around to every network type. So it would say EDGE, then I would see the GPRS circle for maybe a second, then no service, then 1 bar with no network icon, then back to EDGE. The repeat. Yesterday it lost 4G and couldn't get it back but it seemed to remain solidly on EDGE this time. I replicated exactly the conditions as before and it still remained on EDGE. I reset the phone and 4G immediately appeared.

    It seems that if it actually loses 4G, which at work can happen, it is unable to get back to 4G without a reset.

    Should I visit Apple for a new one?
