iOS 7 "No Sim Card Installed"

I too am getting the same "No Sim" issues at random on my iPhone 5 running IOS 7.0.3 I took it to Verizon, and they got me a new sim card. I had the same issue the next day, and returned to the Verizon store who sent me to the apple store. The apple store tryed to sell me a new iPhone for $265 since I was 40 days out of warranty. Very frustrated, and the only way to solve the message is to reboot for me. I followed http://support.apple.com/kb/ts4148 and keep getting this. Hope they come up with a solution or its back to the Galaxy for me.

Come on Apple! Is anyone in Cuppertino paying attention!? Give us some help. Please! This message was only occurring for me every few weeks, now I've had it 4 times jn less than 24 hours. It clears up with a complete shutdown but how customer service oriented is allowing that to be the "fix"? It amounts to zero customer service. Give us some help.

Same problem here.. iPhone5 getting the "No Sim" message around 5 times a day! Re-starting the iPhone solves the problem until the next message. Apple, HELP please (ASAP)!
(This is happening with the carrier vodafone - in Portugal).

Same problem. iPhone 5 running iOS 7.0.3 on AT&T and this has happened multiple times now. Took the SIM card out and reseated it, didn't help. Only thing that fixes this is a hard reboot. Hard to believe this is still happening almost two months after the release of iOS 7.

Same here iPhone 4S call faild phone is no use ipad 3 just says invalid sim or no sim since ios7 helppppp

Same here with iPhone 4 after iOS7 install. Now have 7.0.3 installed. With Telstra in Australia. Normally excellent reception everywhere & fast. Since 7, as soon as weak signal strength, says No Sim Card Installed or Invalid Sim. Only way to correct is to reboot. But this works only if in higher signal strength area. Now rebooting at least a dozen times a day. Pre 7.0.0 no problems anywhere even in low signal strength area. When is Apple going to address this issue? It seems very common everywhere in the world.

Did a complete reset on iPad2 ...worked for a couple of hours, then "No Sim Card" again. Put in a new Sim Card ... worked for about 1 hour, then "No Sim Card" again.

Same thing happens to me, started in less than 24 hours after I installed iOS7! How super annoying!

In my case, I have to reboot a few times and leave my iPhone totally turned off for a while to make the SIM reappears. Which means: takes a lot of time! Unacceptable!

Apple - you'd better listen to your customers!

I'm having the same problem. I've had my iphone 5 for just over a year. The error began appearing shortly after iOS7 was installed and has happened several time since then.

Restarting the phone has always fixed the issue. I've never removed the SIM card since the phone was purchased. To me this seems a software issue as the reboot always resolves the error. If they can't fix it soon then I'll moving to Android with my next phone purchase.

Same problem with iPad 2. Had AT&T replace the SIm card no help. Genius Bar told me iPad was out of warranty and offered to sell me a new one. I told them it was an issue with IOS 7 and was in turn told that if there are 30 people on a forum it's just a coincidence! Really! I'm not a statistician but I wonder what are the odds of the SIM reader failing and then what are the odds of multiple people having their SIM card reader fail at exactly the same time?

I hope I'm not jumping the gun, but after having the same "No Sim Card" problem, trying the various "fixes" ... removing and replacing Sim Card, turning Airport Mode off and on, etc., without a permanent fix, just now I removed the Sim Card and cleaned the inside of the Sim Card slot on my iPad2. To do this I took a thin flexible piece of plastic (it's actually one of the collar stiffeners from a men's dress shirt, but a strip of cardboard would also work. I folded a cut to fit strip of paper towel ( I used heavy duty Bounty paper towel so it wouldn't fall apart ... a piece of clean cotton would work as well) over the plastic strip, soaked it with isopropyl alcohol, and carefully slid it back and forth in the slot a couple of times.

Then I reinserted the sim card and turned the iPad back on. At first I got the no card message again, but after simply turning Airport mode off and on, then wi-fi off and on, it started working again. This was a few hours ago. I've gone back to the iPad several times now and when I've turned it on, it continues to work properly. Only time will tell if this will work, but since I've had the no card message non-stop for 2 weeks now, it's definitely encouraging.

It makes sense, because one of the fixes was to clean the Sim Card. Why wouldn't the Sim Card's receptacle be just as likely to get dirty or have a tiny bit of dust on it, stopping the connection. Wish me luck.

I'm having the same problem. Powering down the phone is the only solution that is working. It seems to happen once a day.

It's not the most annoying thing in the world, but it seems like a software bug if so many people are having the problem, one I hope they fix. However, I could be wrong. I will try getting a new SIM card, as everyone suggests.

I am having the same issue as well. Every day, once a day, I get the "no sim" message. It seems like nothing for sure will work to fix. I guess I'll try a new SIM from AT&T.

I am have the same problem.. Since I updated my IPhone 4 to iOS 7, I been receiving this message very two to three days.. No SIM card installed .. I restarted my iPhone rest every thing and take the sim out and put it on and the same problem comes after a day .. I went to At&t and changed the sim and after few days I'm facing the same problem.. No solution and I think Apple is responsible on all that .. I'm even thinking now to go with samsung at least without headache from Apple every while.. With every updates, Apple send new bug for iPhone users..

People shoul stop buying iPhones..

I've got an iphone 4s and having the same problem. No sim installed straight after downloading 7.0.4. i've been fobbed off by twice by online chat and once by the shop with them saying its a hardware failure and trying to charge me £160 for another phone which i'm not willing to do. Apple when are you going to admit that this is a software issue. Other companies are catching you and will be overtaking you if you dont get this sorted
