    I've got the problem too.  I've had to reboot a bunch of times already.  I've got the 16GB AT&T white phone.  Even my 3G worked better than this.  I only had to reboot it once a day.  Sigh.

    Same problem. Black 64GB 4S. I got the "Invalid SIM" message during initial configuratin, so it isn't an iTunes problem (for me, anyway). I'll head to hte AT&T store for help.

    Add me to the list. I activated on Friday. Saturday I would get an occasional "Invalid Sim" which would clear with a re-boot. It became more frequent this morning until I started to get a "No Sim".I have tried all of the suggested remedies but none of them are working. My AT&T store is closed on Sunday so I am without a phone until at least tomorrow. iPhone 4S 64GB.

    This worked for me...

    It took me about an hour to research the site and get this info...  Go to this URL (below) and follow instructions to remove SIM card.  I lightly blew on the card and the SIM card holder space to clear and it is now working fine... Yippee!!!

    Ok.... I just removed and re-inserted the SIM card while the phone was powerd on. It found the SIM card. Previously I had done this with the phone powered off. I am NOT sure this is the preferred method but so tred with caution!! It seemd to have corrected the, issue for now....

    After spending time in the Apple / AT&T 'the other company can help you' vortex, I took out the SIM while the phone was on, blew on it and 'inside' lightly, and then reinserted. After a minute of the phone showing 'No Service', I was back and activated. I'm not feeling exceptionally confident in my hardware after this, though. The Fonzi fix-it approach shouldn't be required for such a high-end device.

     

    This was after I was told by multiple people that the ONLY solution was for me to go to one of their physical stores. Top notch. getting back on the network allowed me to get the AT&T test texts and a message giving me the Apple Care 800#. Black 4s 32 GB.

    Update from an AT&T customer whose phone is working after getting a new SIM card.

     

    AppleCare acknowledged receiving a  number of calls about SIM card problems and patched me through to a senior specialist who asked me to go to an AT&T store for a new card so that we could rule a faulty card in or out.

     

    The nearest ATT store was out of cards and said I wasn't the first new activation to come in seeking help with this issue. The second storeto visited said they hadn't heard of the problem. They replaced the card and it worked.

     

    That was nearly three hours ago. I'm far from confident that the problem won't resurface -- likely at precisely the wrong time. Will be interesting to see whether any of the blogs or other media pick up on this. As of this morning, none had.

    Fixed. I went to the AT&T store, got a new sim, and it works fine now. Fingers are crossed that this is the full extent of the problem.

    Same issue - the phone worked fine for the first 24 hours or so but then I started getting 'SIM Failure' messages every few hours.  Rebooting fixes the issue and brings back cellular connectivity, but it is really annoying nevertheless.

    I'm having the same issue; I received a white 32GB from AT&T in te mail, activated and promptly Saturday morning there was the invalid SIM; did a reset...all well until today, when I reset 5 times with no luck.

    Read this post, popped it out, blew it aka Nintendo Style, reinserted, fine for 4 hours....

    On a call, SiM disappeared and had to pop out and reset (no more blowing my phone)...

     

    Is te consensus AT&T And VZW shipped dud SIM cards or is it the contacts in the phone?

    Any word on how to address this?


    I've synced back to iTunes just in case there was an upadate but nothing...

    Have't gone back to the store, seems to be acting fine now, but constantly ejecting the SIM to reset is rather lame..

     

    COME ON APPLE!!

    Called AT&T about this issue.  Advised to head to an AT&T store for a new SIM.  Been 8 hours and no problems.....  We'll see.

    I too am having major issues with the sim card.

     

    Has anyone noticed that this is happening and the right side of the phone getting incredibly hot? I have only noticed this SIM Card Failure issue after using my phone to do video chat, or after playing a little Angry Birds, or doing something a bit intensive. The SIM card slot is definitley hotter to the touch than the rest of the phone.

     

    I'm on Sprint currently, and I'll have 3G, use Angry Birds, then boom, I'm down to the dreaded "circle" instead of the 3G on my status bar. Ever since the second sim failure I had, I have not been able to use 3G at all. And I'm getting one bar of service on the low-speed network. Almost seems like my antenna's just fried or something.

    I think one explanation for atleast some of these sim failures could be poorly cut cards! If you have cut your own micro sim card using either scissors or sim card cutter as I did then you may have cut too close to the contact points which can cause the sim to short out on the Iphone or its sim tray! Possibly explains the intermittent nature of the fault!

     

    Here's a link describing what i'm talking about with images of both good and badly cut micro sims!

    You can see images below examples where the cut is too close to the contact points it is important to leave some plastic around the outside edge as in 3rd image!
