    I have had an iphone 5 for a year. No problems with it. I updated to IOS7 and after about a week I got a warning message that said 'no sim detected'. The phone signal disappeared at this point and 'no sim' appeared where it would normally have the dots and 'LTE'. Turned phone off and on and signal came back.

    I have had this happen 3 further times, twice yesterday. Each time it has corrected after a power cycle. Anyone else seeing this?

    I've been having the same problem in ios 7 on an iPhone 5s. I've checked the sim and it is seated correctly. Same as you a reboot seems to fix it temporarily until it happens again in a couple hours.

    No issue with my iPhone 5 and iOS7 update.

    Have you tried the usual remedies of

    settings > General > Reset > Reset all Settings or Reset Network Settings.

    Or a full restore.

    I've had this happening since the 90's, and it has always been due to one of two things: dirt (or whatever it is, oxidation?) or loose SIM card. Take it out, wipe it clean, put it back in and it should be good.

    Well I'm waiting for my 5s to be delivered so its not a big deal for me, more of a nuisance. If its dirt or something like that it seems strange that I had no problems for a year and then with iOS7 I'm suddenly having problems

    Correlation does not imply causation. Just remove it, wipe it clean, see if it works.

    You are right. Correlation does not imply causation. However I have another saying for you - I don't believe in coincidences..........

    I was taking a dump at the same time Tony Romo threw an interception. Coincidence? I don't think so.

    Were you able to resolve this problem?
