iPhone 4S SIM Card Failure -- "NO SIM CARD". Anyone else getting this?
My black 16GB iPhone 4s reported "invalid SIM card" and then "No SIM card" 24 hours after activation. There is a growing number reports of this problem on Apple's user forum.
Anybody here experience the same thing? Some folks have had luck rebooting their phones and/or removing and reinserting their SIM cards. That hasn't worked for me.
If you're having the same problem, I encourage you to report it here and over in this Apple thread : "Sim Card Failure No Sim with iPhone 4S Anyone Else?". Google it and you should find it. There were 22 reports at last count.
Also, please share any experiences you have either fixing this problem yourself or trying to get help with this problem from Apple, AT&T or other carrier.

Yep...me too. It's happened 3 times since I got my phone last Friday. All 3 times the phone was just sitting on my bed and when I realized I hadn't received any calls for hours at a time, I'd pick up my phone and sure enough, I'd have the Invalid SIM message. I reboot and it seems to fix it but I can't figure out why it's happening in the first place.

A little confused. I did not even have to use my sim card
I went from a non Iphone to the 42 and it never asked for my sim card
It has been working for four days without the need of the sim card

^ Your AT&T phone came with a SIM card already installed.
Brief update: AT&T store replaced my SIM card Sunday. Four days later and everything is copasetic, although the phone does tend to run warm.
I share the concerns posted here and on the Apple support forum that the phones are defective.

OK. This just happened to me today. I have an iPhone 4s 16Gb. I rebooted the phone and it seems to be ok now. Can I take this to any ATT store to get the SIM tested, or can I go to an Apple store to have this taken care of under Applecare (the Apple warranty)?
Thanks

Apple may have some SIMS but just go to an ATT corporate store and have them activate a new SIM in your phone. There is not really a way to test a sim except put it in a different phone. If it works then it points to the hardware. Since the iPhones do not store anything on a SIM, getting a new one activated should not cause you any issues or lost information.

The problem is that the tray that holds the sim card is made of metal and makes contact with the sim card. When this happens, it shorts out the sim and you get the 'no sim' error. What you need to do is remove the sim card, place a VERY THIN sliver of tape on the long edge of the sim ( the side opposite the notched side) that sits in the tray. What you are doing is insulating the potential connection point between the sim contact and the metal tray the sim sits in. There are a couple of videos on youtube that show you how to do it. http://www.youtube.com/watch?v=z2y0abjPFfk
Should we have to do this? No. Should Apple should fix this immediately and offer the fix to everyone asap? Better believe it!
Are you listening Apple?

4S 16 Gb white apple store 10/15/11, no sim card problems at all. if you have a sim card problem go to AT&T ask them to replace your sim card for free.

I had the same problem within the very first weeks after I bought 4S Phone. I went to Apple store, they reset it, I got to the street and got the same message SIM FAILURE/NO SIM CARD. I went back and got my phone exchanged. Almost after a month, I repeatedly started getting this message again today. I needed to turn off the phone after noticing this message and turn it back on. That helped. But before I have noticed it passed some time and I have lost an important business deal.
