getting "no Sim Installed" error on iPhone 4

I got my iPhone on launch day, and only had that happen to me on the 4th of July (like7 times...I resolved it by popping the sim back out and in) and then just the other day on Friday 10/8. Got it like 5 times that day. Popped the sim like before and then all was good UNTIL just 5 minutes ago and it happened again. I just did a reboot instead of SIM pop. We'll see how it goes.

 

Maybe a new sim for the both of you may be the fix. Pop on down to at&t or your provider and pick one up. Good luck.

 

LoL guess the joke is on me!! I'll be taking a trip to att to get a new sim as mine has done it several times in the last few hours!

 

Got the same error everyday for two weeks. Put a piece of scotch tape on the non-contact side and haven't got an error since.

 

Interesting, all of you guys too? Yeah, this has happened to me about 4 times now. Oddly, I can usually fix it by toggling Airplane Mode. It seems odd to me that this would work, given that the No SIM error sounds more like a hardware issue while toggling Airplane Mode is a software fix.

I've also been considering trying a new SIM anyway.

 

Had the same problem, used to happen about twice a day. A reboot would usually fix it. But it was pretty annoying so i went to the apple store and they replaced the phone no questions asked.

 

My first iP4 had this. Took it to Apple, walked out with a new one in 15 minutes. See my sig...

 

Had this problem on mine as well. Got it replaced thankfully. They likely problem is that the metal part of the sim is contacting the metal tray and causing it to short. A quick temp fix is to try using a small amount of thin tape to hold the sim higher in the tray. Also, you can always go to att and get another sim, hopefully one without any movement in the tray.

 

Well mine literally started doing it today, after I read and posted to this thread. I was jb on 4.0.1 and tried to upgrade and got an error from iTunes. It then started happening. Updated and it has done it 2 times. If it continues I will visit ye ol apple store and swap.

 

To anyone else this is happening to: try togging Airplane Mode on and off to see it that fixes it (temporarily) for you as well. Ensure that you leave it in Airplane Mode for 2 seconds or so before toggling back, as it appears that if you toggle too quickly it doesn't finish.

It'd be great if you could report back here as to whether or not that works for you.

 

Had same issue today with no sim installed. Took it down to AT&T and sim card was bad. They installed a new one and everything is back to normal now.

 

Having the same problem. Called Apple last week, they suggested the following steps:

1) take sim out and put it back in (didn't work)
2) restore phone and set up as new (didn't work)
3) get new sim (worked so far)
4) take to Genius Bar for new phone

It's been about three hours since I got the new sim and it hasn't happened since. However, I'm still inclined to take it in to the Genius Bar (have an appointment in two hours) and see if they'll replace it.

Any idea if they can tell through diagnostics if the "No Sim Card Installed" notification has happened and when? Partially I'm afraid I've missed one and partially I'd just rather they swap it out so I don't have this problem again.

 

Any update on this? Did the new SIM fix the problem for more than 3 hours?

 

My wifes iphone 4 had the same problem today, after searching online for a fix, I found the simcard tray fix with tape, I used their picture to show what I did on mine.

Before this tape mod I TRIED EVERYTHING......Restore, Simcard insertion and removal several times, Airplane mode, update from 4.0 to 4.1 lets say nothing worked.

In my case the simcard electrical contacts on the outside edge were smaller and not close to the outside edge, but I did find that the sim card electrical contacts on the side are very close to the metal tray.

I just added a tape to make sure the simcard electrical contacts doesnt short with the simcard tray. And so far is the only thing that worked great SO FAR.

I tried to move the simcard tray once it was installed with the tape mod and so far I havent had any problems.

Here is a picture of what I did photoshop style

 

Does that fixed the issue til now?
