iOS 7 "No Sim Card Installed"

Also intermiatently getting this error. Rebooting the phone always fixes it. But its happened 3 or 4 times.

Ive been having this issue too since downloading that awful ios7.. Will be visiting Verizon tomorrow..

A had the same issue with updating to iOS7. Solved this by configuring the APN setting. After I have entered a valid APN string all is working ok.

Same problem here. Upgraded iPad 2 to iOS 7. Worked fine for a couple of days, then started getting intermittent "No Sim Card" messages. Turning iPad off and on worked until yesterday. Have taken out Sim card and cleaned. Still doesn't work. Also my iPhone 4S intermittently loses some of the Blu-ray controls for music through my 2013 Toyota Rav4. Works for a while, then doesn't. Have to remove device and reinstall to get it working. Also won't send email.

Sorry you're having trouble, I've had the "no sim card" message pop up on my iph5 a few times since upgrading to ios7 too. I don't have an answer different from any of the other submissions but wanted to join the ranks of hasseled. Apple! Please get this figured out because I'm getting tired of the message and accompanying shutdowns, along with wondering about missed communications! Thanks.

Got new sim from verizon. No charge. Problem solved.

A new update came through a few hrs. ago. It didn't mention anything about the SIM card problem but as soon as it finished installing, the card is working again. I'm hoping it keeps working.

Ignore my post above. SIM card was working last night right after latest fix install but first thing this morning it's not working. Will try new card.

Same problem and even the latest update haven't fixed that. At the beginning, I was able to temporary fix it by resetting the device, but it hasn't been working for a week now. No problems before the upgrade.

Same exact problem. Was never a problem before ios7. Looks like microsoft, starting to work that way too.

When I installed iOS 7 on my 32 Gb iPad 2 w/3G, I started getting the "No SIM card installed" message. Toggling the iPad on/off would temporarily fix the problem, but as of today, the "No SIM card installed" message was permanent. I went to AT&T Corporate store first to replace SIM card but that did not solve the problem. Set an appointment at the Apple store and they could not resolve the problem so they sold me a "new" iPad 2 for $249 plus 6% tax.

I'm extremely disappointed in Apple. This is obviously a defect that needs to be addressed at their expense, not their customers. Ten hours of work, wasted fuel, and $263.94 out of my pocket and I'm back where I started, perhaps. My "new" iPad2 comes with a only 90 day warranty, so I wonder how soon I'll have this problem again.

Thanks, smikez. Guess I will have to get a new SIM from Verizon too. 😐

It's ironic that an iPhone running on Verizon's CDMA network would bork because of an issue with the SIM card, which only serves to access GSM networks! I did not expect ever to have to return to a bricks-and-mortar Verizon store when I picked up my iPhone 5 on launch day last year. Good thing that T-Mobile US now has the iPhone as well, because I will be switching from Verizon back to T-Mobile as soon as my 2-year contract is up!

I'm having the same issue. iPhone 5 on Verizon.

To follow up on this, I did go the Verizon store where I originally purchased my iPhone 5, and they replaced my SIM card with a new one free of charge. With the new SIM, my phone has been working flawlessly once again.

The problem is apparently a corrupted SIM card. This is something that happens occasionally and randomly. While iPhones running iOS 7 may appear to have a higher incidence of corrupted SIMs, this has happened with previous-generation iPhone as well as other brands of (non-Apple) phones, both GSM-only phones and GSM/CDMA capable phones like the iPhone 5 and up.

Bottom line: While the "no SIM" error is a PITA, there is an easy fix. Just get a new SIM card to replace your corrupted one. If you're on contract with a decent carrier, they will likely replace your SIM free of charge.

Same problem. ios 7 ipad 2, No Sim error. VIRGINBROADBAND ( Australia). Tried 2 SIM cards, same result. Initially solved by airplane mode on/off but now getting nothing. VERY annoying.
