Error Message "no SIM card installed"

Hello, All has been fine with my Iphone but..... I just got on a plane earlier today and watched a Heroes episode on the phone... about half way through I realized the phone said "No Sim" in the Service Carrier area (top left).

Now I'm home I have restarted 10+ times, re-seated the sim 5 odd times.........no luck. I put my wifes sim card in and it knew it was the wrong carrier sim, I also took off the Next Sim 2 from my sim and tried that on its own..... Again, it read the sim and knew it was not the right carrier. I put the Next Sim 2 back on tried again but it just went to "no sim installed again"

I live in Australia so its a huge pain to send it back.... can anyone help??
thanks


I have a "Next Sim 2" on my Vodafone sim with a JB'ed 1.1.2 otb.

    Yes I have the same "No Sim" error with firmware 1.1.2.

  • damaris Jan 19, 2008

    i live in ireland, bought the iphone 1.1.2 from the us and got a next sim 3 - i had no problem jailbreaking, downgrading and upgrading the firmware. i can now (with the next sim 3) get an o2 sim to work in the iphone but i cannot get my vodafone sim to work!! is there something else i need to do for the vodafone sim? i've tried using the vodafone sim with the next sim 3 in another phone but it doesn't seem to make a difference to the iphone which still tells me the vodafone/next sim3 combo is an "invalid sim". i'm sure you can all relate to being so close and dying to use the !&£$^ing thing!!! any suggestions?

    I indeed have the same problem. My Iphone has worked properly for one month and then, al of a sudden this problem accured and did nog disappear. Only a hard reset seems to help. Can this problem be caused by swithing between networks (home wireless vs telcom provider)?

    "No SIM card" x 24 hrous.



    I looked at all of the advice and after multiple restarts I inserted a paperclip in the top and took out the SIM card and holder. i reinserted both and it works well now. so far. . . .

  • jerryfrancel Nov 26, 2008

    Updated my 3g to the new 2.2 software and have been having the "No Sim" message ever since. I have re-started my phone 10+ times- very temperory fix (5-45 mins) I have placed a new sim card in my phone from ATT, no good, I have re-stored my phone 2x and phone was fine untill.......I put my applications back on my phone. I have not figured out witch app could be causing the error yet but I think that it may be APP SNIPER. What good is the phone without apps?

  • mvmichael69 Nov 27, 2008

    my Blackberry at& t doesnt read the other network sim card. It show's invalid sim card. How to unlock it. Please help me .

  • almoagnadna Feb 12, 2009

    Same problem, although mine is intermittent.



    I will typically see all my bars go down to a flat line (or close to it) and then a few minutes later it will read "No Sim." Usually if I reboot the phone, it will reset and 'find' the SIM card again. /However/, it will maybe last a minute or two, or a few hours. It's gotten increasingly worse, and will just cut me out of phone calls mid-conversation, and only sometimes will come back after I restart. It's getting VERY frustrating.



    Any thoughts are appreciated!!!

  • Anonymous Mar 22, 2009

    My phone fell and I had the same error. I made sure the SIM was in all the way (it had come loose), and viola! It worked like a champ.

    everything was fine on my phone then yesterday it started randomly saying no sim. now im having to restart the phone or put it in and out of airplane mode to make it read my sim, any ideas on whyt his is happening or how to fix it?

  • alannabob May 19, 2009

    I am having the same problem with the "no SIM" msg. It sometimes recognising the SIM if I turn the phone off and on again or select airplane mode and then deselect. I never had this problem until the past month and I have no APPs on my phone as I have not had a PC until now! So, despite what one user with a common problem may think it cannot be related to APPs. It could be the new version 2.2 as I never experienced this issue before. Plus I don't actually know where the SIM is in the phone or how to get it out...?? It was inserted at the shop and I haven't touched it since. Also, my phone has never been dropped or anything so I don't understand how the SIM could have dislodged?! Has anyone contacted Apple direct about this?

  • sisk May 23, 2009

    Have the same problem, the message no sim card installed keeps popping on and off while no service shows on the top left side. Tried to reset all settings, reset network settings, clean the sim card but no luck shows till now. What else can I do? Can someone help me?

  • damaris May 11, 2010

    hiya, i put a post on this thread outlining the details of my problem - i tried your suggestion by putting the at&t/next sim 3 (yeah - i have the next sim 3, not sure if that'll make a difference) into another phone (blackberry pearl) but that phone didn't recognize a sim at all. all the same, it was worth a shot so thanks for the idea!

Hold down the power switch at the top and the main selection button at the bottom. After a few seconds a new screen should come up that allows for shutdown should you slide the slider to the right. DO NOT SLIDE THE POWER OFF. Keep holding the two buttons down. Wait until the silver apple logo comes on the screen. At this point you may release the two buttons. Continue to wait while the iPhone reboots. Once the iPhone finishes booting the "No Sim" message should be gone and you should see bars again. No new sim card or reactivation required!

Ok so i've been having the same problem for about a week and I finally found a fix for it, atleast temporarily. First, turn on airplane mode so it doesn't try to read the SIM card. Then, restart the iphone regularly. Turn the iphone back on and then turn airplane mode back off and if you have service in that location, it should work. I hope this works for everyone else. let me know

I simply popped out the sim card: look at the top of the phone- it's barely visible, but there is a tiny **** with hole in it. You have to get a safety pin or small paperclip to insert into it. It will pop out. I blew the dust out and wiped the card on my shirt. Popped the card back in and voila!

Mine would work for about 10 minutes after a reboot or network power off/on (airplane mode on/off cycle).
It appears that small dents appear on the sim over time reducing the pressure on the contacts. Possibly these could be caused by contact corrosion. But cleaning the contacts didn't fix it. Getting a replacement SIM should fix it long-term.
I put a single layer of cellotape on the back of the sim to make it a tiny bit thicker. Working now.

The easiest way to get this thru is take your sim out and clean it and put it back in and make sure you really press it all the way in, try pushing it more until it recognizes it. It worked for me and i had been trying many things!

I live in the SF Bay area, which has notoriously bad 3G network service, and my iPhone is about 9 months old. I went to sleep listening to music on my iPhone and woke up to the "No SIM installed" message.
I'm in favor of starting with the least invasive solutions first, so I did a few hard reboots. It didn't work.
I read about resetting network connections as a solution and was about to do that next when I read somewhere to try putting the phone into "Airplane Mode" and doing a hard reboot, then taking it off "Airplane Mode". THIS WORKED for me. As soon as I took it off "Airplane Mode" it redetected the network.

This morning my phone said "no sim". I just went to "settings", scrolled down to "general", then scrolled down to "reset". I pressed "reset all settings," and it worked!! I can now use my phone and "no sim" is no longer on the left hand corner.

Try putting a slim piece of paper behind the SIM card. This will press the card firmer against the contact pins. So far, this seem to work for my iphone 3g.

The reason this happens is when you dont get service, the phone goes in no service mode. In order to fix it"

Take out the sim from iphone and put it in another phone and make a call
Then take out the sim again and place it back in the iphone and make a call and it should work.
This is bad because when you dont get service it will happen over and over...for me i carry an extra phone in my car just incase it happens. Thanks.

    Okay, for those of you who have been having issues with the intermittent "No SIM" error, this may be a possible solution. As many people have, I'm sure, I've dropped my phone a few times. Every time, the SIM card pops out and then you have to slide it back in. After being dropped a few times, things inside (such as electrical contacts) may jar loose or get bent slightly to the point where no matter how many times you slide the SIM assembly in it will not pop up.

    Before I share my find, if any of you are experiencing the intermittent "No SIM" error, try pushing on the SIM assembly while it's still inside the phone AND while its not recognizing the SIM. Unlock screen as you normally would, and see if the "No SIM" error goes away. If it starts recognizing the SIM and you notice its working but when you release the pressure the error comes back, read on.

    WARNING! (Just in case) I am not verifying this as the "perfect fix". Do it at your OWN RISK, as this may damage the internal components of the phone. I take no responsibility if YOU break YOUR phone.

    I had this issue recently and I used a somewhat unorthodox way to fix it. At the very bottom of the slot in the phone, there is a "sensor" (or contact) that seems to engage the SIM circuits in the phone when the SIM assembly is inserted.

    1. Take a small piece of scotch tape (I used scotch tape b/c its very thin) and wrap it around the very end of the SIM assembly. However, don't press the tape against the end of the assembly, instead leave about a 1/32" of the wrap of the tape sticking out, as if to make the SIM holder a bit longer.
    *Make sure the tape is sealed nicely or you may have an additional problem, getting the tape stuck in the slot!

    2. Reinsert (carefully!) the SIM assembly in the slot. Be sure to push it all the way in, as far as it will go.

    3. Check and see if it works! If it does, you're finished. If not, then I suggest taking it to your nearest Wireless carrier for professional advice.

    Hope this helps!!

Hi,
i'm not sure if this will help but, the first time i tried to use my 1.1.2 otb with a turbosim it didn't work, after trying almost everything, i was told by the seller of the turbosim to setup the turbosim first with the at&t simcard that came with the iphone and then attach my simcard to the turbosim and it worked fine after that with no problems. Maybe try the setup process again with the at&t simcard attached to the next sim 2 and then attach your simcard to the next sim 2 and see if that works.
n.b you wont be able to do the setup with your iphone, it won't let you...you'll have to use another mobile phone preferably an unlocked phone to carry out the setup process.

Error message no sim card installed despite sim being in place.


This is a simple fix. Just pop the sim card out and put it back in. Sometimes you only need to disconnect the sim totally to refresh the cellular connectivity.

I assume that you have a valid SIM card inserted or your service provider has not disabled your mobile line.
Please check if you have an Aeroplane ICON at the top line of your iPhone display. If yes, go to Settings and disable Offline or Plane mode. The phone should work now.

You can try these steps just as a work around:

No SIM card installed


I too have had the "no sim card installed message. What has always worked for me is to go into settings and put the phone into airplane mode for about ten seconds and then switch back to regular mode which causes the phone to reconnect to the ATT network. The sim message goes away. This is also a good fix for when your phone isn't connecting to 3G or showing an "E" instead of 3G.
