ATT Iphone 6 intermittently says no sim card installed, but works the rest of the time. thoughts?

Had a simalar problem. But we weren't getting any service. AT&T said it was a defective SIM card and pretty much everyone that bought an AT&T iPhone 6 from the online store had a defective sim. had to buy a new sim from best buy because att were sold out because the problem was so wide spread.

Original iPad 3G 64GB intermittantly says no sim card installed

My iPad, original 3G 64 GB intermittantly says no sim card installed. There is no pattern as to when this occurs. Retarting the iPad sometimes helps. I have removed the sim card, blown out the sim slot and reintalled the sim card. I have done everything I can think of short of restoring back to factory condition. I have since been lent another iPad (identical to mine) and have installed my original sim card. So far, no issues. This leads me to believe it is an issue with the iPad itself. Can anyone offer any suggestions or help?
Thanks,
Art M.

If you're stuck within an app or you've noticed a problem, simply hold both the home button and sleep/wake button at the same time. It's important to keep your fingers on these buttons until step 3.
After a few seconds the red ‘slide to power off' screen will appear, simply ignore this. Ensure your fingers are still holding down the home and sleep/wake switch.
Shortly after you should see the Apple logo, it's now safe to let go of the iPad's buttons. Your iPad should now boot, beware this process can take up to 15 minutes or so.

Jailbroken phones can not be discussed here.
It's highly likely that it is now bricked. The jailbreak most likely did permanent damage. There are lots of reports of previously jailbroken/hacked phones that become unusable when attempting to apply a legitimate unlock.

My phone is saying No SIM card installed, when I clearly have my SIM inserted?

My phone is saying No SIM card installed, when I clearly have my SIM inserted. I can't make or receive calls. What can I do to fix this?

Did you already try to remove it and put it back again?
When changing the SIM card, power off the device prior to opening the SIM tray. After you have changed the SIM card for your iPhone you may need to reconnect it to iTunes.
iPhone keeps a record of previously inserted SIM cards, but if the carrier name of your SIM does not show up in the status bar after you changed the SIM you will need to reconnect iPhone to iTunes. If you do not connect iPhone to iTunes after changing or reinserting the SIM, iPhone may not work as expected.
If iPhone does not work with the SIM card after connecting to iTunes, you might need to restore your iPhone. Consult the iPhone User's Guide for more information on iTunes and iPhone.
If your iPhone does not show up in iTunes (on the left hand side of the iTunes window under Devices), please see the following links for assistance:
iPhone: Not recognized in iTunes for Mac OS X
iPhone: Not recognized in iTunes for Windows

If this does not work, contact your provider, maybe your SIM is damaged.

This Apple doc might help ya out -> iPhone: Troubleshooting No Service or No SIM
If those tips don't take care of it, try contacting the carrier to get another SIM.

I've had my iPhone 5 forever & it started with a message No SIM card installed. How do I fix this?

Insert a SIM card.
If one is already inserted, remove and re-insert.
If the problem continues, replace the SIM.

Why does my iPad keep saying no SIM card installed?

I have an iPad 2 IOS8. It keeps saying I have no SIM card installed, why is that and why do I need a SIM card?

Hi CusMan!
I have an article here for you that can help you troubleshoot that issue:

The article is written toward iPhone users, but the steps for troubleshooting on the iPad are the same. Thanks for being a part of the Apple Support Communities!

AT&T Unlock iPhone 4 without a Sim Card installed question

I just put in my request to unlock my iPhone 4 from AT&T.
My contract has expired, and my old phone number is no longer active as of about 2 weeks ago, I also no longer live in the US (I've already travelled abroad), but they said that it would have no problem to unlock my iPhone as it's all done via iTunes.
I still have my old AT&T Sim card, but the number is not activate and like I said I'm in another country.
I have heard for the unlock process to be completed you need an activate sim card installed in the phone. Does it matter what carrier's sim I use (can I use a local one?) or does it absolutely have to be an AT&T sim?
I'm in Dubai now and have an active prepaid du sim card (they said it can easily be cut to micro-sim).
Contacing AT&T from here is a nightmare (the "international" number they gave me won't dial out and the website won't let me access my old account info since it's closed now and thus can't access their web chat either).

From another poster in the Communities:
Stipulations
•     Phone must be off contract or you must be in the military traveling abroad.
•     Account must be in good standing for the last 30 days.
•     You must have valid email or phone number where you can be reached when the unlock is completed by Apple.
How it works:
1.     Call AT&T at 1-800-331-0500 and go through the prompts to get to a customer service agent
2.     Have your IMEI # ready along with your active email address and current phone number
3.     If your phone qualifies then AT&T will submit a request to Apple to authorize the unlock on your phone. (AT&T will tell you right then on the phone if it can be done )
4.     Make sure you get your case number in the event something doesn't go through so you can get support from AT&T.
5.     Once you recieve the email from Apple, open iTunes and transfer purchases, backup your phone and then perform a restore.
6.     Once this process is complete your phone should now be unlocked to use other carriers.
It will be up to you to find a way to call a US 800 number from outside the country; do a web search and you should find suggestions.
Regards.

IOS 6 installed but now it says no Sim card installed....what the??

Ok I believe I got iOS 6 installed finally...... But........I start the ohone up now....it wants me to pick language and then country which I do....then it says there is no Sim card installed ....say what?.....its been in there for 4 years......whats up with this.....does Apple have a cure for this?
I have removed it a few times and reinstalled it....same thing

Most likely your phone was previously hacked to carrier unlock. When you updated, the hack was removed and the phone re-locked to its original carrier. It will now operate only with a SIM card from that carrier.

IPhone 3gs shows no Sim Card installed in newly unlocked phone.

My uncle has just givin me his old I phone 3GS which was locked on Orange.
He has paid for the phone to be unlocked and orange have emailed over the confirmation that it is unlocked and how to unlock it.
This is where the problems start. Windows recognises that there is a phone and I tunes tries to activate the phone but it cannot and the No Sim Card installed message appears (even though there is a brand new Tesco I phoen sim). I have taken the phone into recovery mode and restored from there, however this has still not resolved the problem.
Once the system restores the software the phone restarts to the menu screen and the same message appears.
HELP!!!!!!!!!!!!! it is so frustrating.

Why does my iPad say No SIM card installed?

When I plugged in my ipad to charge a message came up that said: No SIM card installed. Is this OK?

Check the right and left sides of your iPad for a small hole the size of a paper clip (remove your smart cover if you have one). If you see this, then you have the wifi + cellular model. If you do, use a paper clip to remove the sim tray (or the sim removal tool that came with your iPad if you have it) as shown in the image below.
If the tray has a sim card in it, push the sim tray back in to re-seat it in the side of the iPad, then turn it on to see if the error message re-appears. If it re-appears, take it to a Verizon store and have them give you a new sim card.
If you have a sim tray but it is empty, you'll need to go to a Verizon store to get a sim card for it.
