Q: No SIM card installed, No SIM, Invalid SIM card

Hello,

I'm getting No SIM card installed on my iPhone 4. I got a new SIM card and 15 minutes later same error. I've reset network settings and also tried a restore with no luck. Genius Bar recommended wiping and starting over without restoring from Backup. Was going to erase mine and start over tonight but....

My wife bought a brand new iPhone 4 from AT&T today... At exactly the same time both of our phones came up with the No SIM card installed message! Her brand new iPhone 4 said the same thing.... This is after I sync'd it up to iTunes, only a few songs and a bunch of apps.

There is something going on with either the network or something with the phone or iTunes causing a problem with the phone. I've almost pinned it to something in iTunes 10.1 because I think this started happening about the same time I updated to iTunes 10.1. Both of us are now on iTunes 10.1.1.4.

iOS 4.2.1 on both phones... Anyone else experiencing similar issues?

Thanks

    Replaced my phone at the Apple Store, no more issues! Thank you Apple for making the process quick and simple.

    I called Apple Support and they suggested going into Settings, turning the Airplane mode ON and then OFF--and this worked! Now connected again. FWIW, they also suggested popping out the SIM card and reinstalling, but I didn't need to do this. We'll see if the problem recurs

    I am having the same problem. I went to AT&T to get a new SIM card as someone suggested in another thread. Now I still get the same error message, but a lot more often at least once or twice a day. I have done hard resets each time and sometimes it works sometimes it doesn't. Tech support suggested going to the Apple store, but the closes one is about 3 hours away.
    As far as iTunes update, I think you are on to something because that is about the time mine started acting up. I am hoping an update in iTunes or the phone software will fix the problem.

    I have been having the same issue intermittently for the last couple of months. The first time, I read on here to pop out the SIM and make sure it was clean (I suppose it could get linty or whatever) and that stopped it for about a month. But now it happens a lot the last few days, and often if I put it down while it's in that "No SIM" state, it will lock up and then crash.

    Sounds like I need to go to the Apple Store?
