I have had my iPad 2 for about 2 years now and have never experienced this problem a few days ago. I live in Hawaii and had taken a trip to Colorado. IPad worked fine while I was away. On the last flight back I didn't use my iPad so I turned it off when told to do so before takeoff and didn't turn it on until I returned home. When I did turn it on, I got the "No Sim Installed" error message. Tried turning it on and off a few times but had no luck. Decided to try letting the battery drain so I let my kids play with it until it shutdown because it was out of power. Plugged it in to the wall and left it overnight. In the morning when I turned it on, the Sim was back. Working great so far...

So here's what worked for me. In my case I deactivated my cellular plan on my iPad mini thinking that I was just cancelling the auto-renewal (like a lot of people seem to do). Went to my local Verizon store to buy a new SIM card - the iPad mini kept giving me the "SIM card not installed" message (even though the old deactivated card could still be recognized). Spent hours on the phone with Verizon support and searching for help online but nothing worked. Verizon said that the SIM card is likely defective and suggested that I get it replaced. Before doing that I decided to try one last thing: I cleaned the contacts on the card with a Q-tip and some denatured alchohol (which doesn't have any water in it like regular rubbing alchohol). It dried quickly and when I put it back in the iPad, lo and behold, it was recognized!

First of all, I have to thank God for giving me grace to do some things that seems impossible, i always have this feelings of there must be a way and it has always be helping me. here is the solution to the problem of 'ipad 2 no sim card installed'
1. Look for the pin(for removing the sim Tray) that came with your ipad.
2. Use it to remove the sim tray
3. Goto settings and Erase all Contents and Settings
4. Insert the base of the Pin into the sim card opening and use it to scruble the panel inside up and down gently. (Note, the original follow come pin that came with your ipad)
5. Re-insert a good sim card with the tray and you are good to go. 100% work do not panic.

I've had the same problem as most everyone on this thread, unfortuntaley nothing has fixed the problem. I purhcased the ATT 3G iPad for use in Europe and in 2011 everything worked fine. We're getting ready for a trip in August and went to turn on the Cellular Network earlier this week and that's when the problem started.
As soon as Cellular Data was swiped (in Settings), the NO SIM error appeared in the upper left of the iPad screen. I've since had the SIM card replaced at ATT and taken the iPad to an Apple store. We were told the iPad needs replaced at the Apple Store.
We're looking for any help or suggestions - we've tried replacing the SIM Card, restoring to factory original settings and restoring the iPad from our computer.
Could this be something as simple as a setting from an App related to notificaitons?

I have had this issue on and off for a few weeks now and the last 3 days I have constantly had this message. I tried some of the suggestions and the one that worked for me was turning my device off, taking it out of it's magnetic case, leaving it off for a few minutes then turned it back on again. Hey presto, it's working again. I suspect it is something to do with the magnetic case. Going to leave it out of the case for a while and put it back in, in a few days. Will update :)

I said I would update on my findings, so here it is. Had my ipad mini out of the case for couple of days. Today the message came back. I have tried different things to get the SIM card to work, turning my ipad on and off, toggling airplane mode, hard resetting, letting it run down and charging it and none of these worked. I managed to get the SIM card out as I haven't touched the tray since the SIM card was placed. I blew into the tray hole and cleaned the sim with a cotton cloth, placed it all back in and it is working again for now. Will keep you all updated. :)

I have been an Apple consumer since 1985 and have kept coming back for more, without any major concerns until July 23 when out of the blue I got the No SIM message. I have tried every suggesting, including new SIM card from Rogers (Canada) and at best have had a few minutes service before the No SIM message reappears. APPLE has to now this is a design flaw of some sort, and it is unconscionable they are not taking responsibility for this. My 2 year warranty expired in April, so I am now left with wifi only, seriously hurting my business dealings. APPLE, address this problem, and give us replacements! Anything less will harm your reputation beyond repair.

I had the same problem with my iPad 2 and after weeks of trying all the suggestions to get it going I eventually got it to read the sim cards by removing the sim and slightly bending the sim tray. On my 3rd attempt in very small amounts of bend the iPad read the sim successfully. So far it is still working.

I'm not sure were eveyone is based, I'm in the UK and I had "No Sim card" message yesterday, so i want to see the Apple guenues bar and for some reason my 3G ipad did not reconise O2 sim card but it will work with 3G sim.. So the guys at the genues bar was not sure what to do.. They advise I reset ipad and hope that will work, but saddy it does not, any idea? 3G is not the best next work so am not sure I want to go with that sim, or I will have to get a refube ipad which will cost me £200.00 Any ideas?

SIMPLE: This sounds too easy but I had removed the cover to clean my ipad for the first time and when I replaced the cover this message appeared. I did a search of the problem and amongst all the technical posts a few mentioned 'covers' and somehow removing them can cause this problem.
1. I turned off ipad.
2. Removed cover again.
3. Waited few minutes and turned ipad on. .... 3G had returned !!
4. Carefully replaced cover watching 3G remained.
PRESTO. I am a senior citizen so have no clue how this worked but give it a try.nnif anybody can explain I would be interested.

I had this problem for two months, tried resets and everything. But it appears that for me this problem has hardware - weak contact - nature. I also tried to insert a paper clip. The clip hasn't made it into the device, but the applied pressure evidently forced sim card beneath and 3G works now. For how long - to be researched.

"NO SIM CARD INSTALLED ERROR" iPad 2 (32 GB model)
So here is my story, what ended up actually fixing the problem.
After 3 years out of the blue this error came up. being a Tech, tried some tricks, hard reboot, sim card removal, hair dryer heating the contacts of the sim card slot, replaced 4 times the Sim card, visit the Apple store etc (AT&T people starting recognizing me already), but no succes. I also "had" unlimited data on my Iphone 4 and being a frequent traveler, for me that and the 3G on the iPad was important.
After my last visit with the AT&T store I went back to the Apple store and they would not even attempt a repair, what surprised me since there is nothing wrong with my device than the above mentioned problem. Being an Apple Fan, (having multiple devices within my family) I agreed to buy a new 32 GB Ipad 2 with 3G for a fixed price of $249 + tax (WA state) and return my old iPad. Although the device wasn't available, I left with an unhappy feeling not sure if I had made the right decission. Apple would call me when ready to pick up. This give me a few days to think about it and when Apple called that the new device was ready for pick up I decided to cancel the order.
I went back to AT&T (5th time) and decided to cancel my monthly subscription of 2 GB data for $25 on my iPad as well cancel the unlimited data on my iPhone for $30. (this was done instantly by AT&T without any questions!!) I changed my monthly service to a 5 GB data package with Tethering and use my iPhone as a personal hotspot.
Guess what!!!, after an hour or so when my subscription was canceled on my iPad and my unlimited data on my iPhone was canceled, the error message was gone and I got a message on my iPad (left my old SIM card in) that there was no data package available and to go to "My AT&T to sign up! Seriously, What ??
Now of course I got curious and took my active sim card from my iPhone, put it in my iPad, and guess what! 3G is working fine again (turned of Wifi of course) I had this done before when both my accounts were still active as normal and it didn't work. Now I wonder what game AT&T is playing with this. Not a happy camper after all.

After reading all the posts regarding this issue I'm convinced that this is a hardware failure; one that Apple isn't interested in reparing unless your iPad is still under warranty. The sim card slot on my iPad 2 gradually declined to the point where it wouldn't recognize the SIM at all and it still won't. No amount of tricks or gimmicks will bring it back whether it is changing the case or toggling the device in and out of Airplane mode. I suspect that the people who had success with like techniques had a later failure or will shortly. Either that or mine is deader than normal.
I contacted Apple both on line and in the store and while their customer service is excellent the only viable solution they were able to offer was to purchase another iPad which I am understandably reluctant to do. So, if your iPad worked after trying one of the fixes described on this forum then congratulations. The only advice I can offer is that it seems that the more I tried switching out the SIM card, or just reinserting the old one, the quicker the error message would reappear. The error could be tied to a gradual failure of the connection in the SIM card slot.
Or maybe the magic ran out.

That sums it up nicely. I finally gave up trying to fix my iPad 2 and instead relied on setting my iPhone to personal hot spot when i needed to use it. I think the very least Apple should do is offer a substantial rebate on purchases of any new iPad replacement. Sadly, I think they will choose instead to ignore this hardware problem until the complaints just fade away.

Thanks so much for this post. I have an iPad 4 and kept getting the No Sim Card message. I tried everything then found your post. When I took the iPad out of the case and left it off for 5 minutes and then turned it back on it worked. I have had it off and on again the next day and it still worked. :)
