iPhone 5: No SIM, SIM Failure

I bought iPhone 5 week ago and in the same day aftet few hours use the Phone was saying "SIM Failure" (AT&T SIM). Needed to reboot the phone and works again.

Now after one week the phone is complaining "No SIM", four times so far today. Every time after one time or two timesboot works again.

Even phone is on the table and push menu button to go out from screen saver there is "No SIM".

So for me this sounds that it is NOT a HW contact problem, but its more likely the SIM interface problem between the phone processor and SIM card.

Same problems were suffered like ten years ago with normal SIM card when it was new and now the new Micro SIM is causing same "childhood disease"!

So, I'm really frustrated if this continues!!

So, Apple please offer soon a SW update with improved SIM_SW to get rid of this!!!

And If You say that just clean or re-insert the SIM, something has gone wrong badly with introducing the micro SIM card!!!

Waiting for SOON fix!!!

Just got a new SIM card from AT&T (no charge). So far, so good. I'll repost if the problem returns.

During the nightime my phone was again in the "No SIM" -mode. Needed to reboot two times and then worked like ten minutes and went back to "No SIM". So I removed the SIM card and put it back, now 30mins ok....

Yes, need to really try to get a new SIM from AT&T if it somehow fixes the problem...

Did You got any explanation from AT&T why the new SIM shoud be better?

No explanation, but she acted not surprised and just whipped out a new card as soon as I told her the problem. She seemed "experienced" with the problem.

I had the identical problem on an iPhone 5 received (as an upgrade) directly from Apple. "No SIM" ever few hours. A full power-off/power-on cycle required. Verizon swapped the SIM at no charge and the issue appears to be fixed.

I had a similar problem yesterday with my 5 AT and T. In the bowels of lower Michigan in an area of good service it just stopped working. No service error. No phone, not even emergency call. Went to AT and T and they swapped out the sim and it is now working. I tried everything, restore, reboot, retool to no avail. Hope this settles it so I dont have to carry an emergency phone in the car for when my sim blows out

I had the same problem with Sprint. Went to Sprint and they could do nothing. Took it into Apple and they said the "NO SIM" is a hardware problem and they simply replaced the phone. I then had to go back to Sprint who replaced the nano sim card to reactivate the service. So far, no problems.
