ITunes restore iPhone SIM Card no longer works.

Ok, I had all my contacts and information backuped onto my computer so I could easily transfer them from my 16GB 3G to my new 32GB 3GS. After being restored and synced with my computer my SIM Card no longer works. It wont let me place a call or text. When I un-plug the SIM Card and then plug it back in a message comes up saying invalid SIM and then disappears. Also it either has 1 "bar" with the rest flat and no AT&T logo or 3G, or says No Service.

Sounds like you need to call AT&T.

  • Iwhy is my sim card no longer working after restoring my 4S

    I bought a 4S and had to restore it now my sim card no longer works in my phone. I tried it in another phone and it works so its not the sim card.

    I would try two things. First go to the store for your phone carrier and get a new sim card.
    If that doesn't work, schedule and appointment with a genius at your closest apple store. 

  • My iTunes got deleted off a (no longer working) computer. Is there a way I can transfer all content from my iPhone onto iTunes on a new computer? I want to update my phone, but do not want to lose any music off it when syncing it.

    My iTunes got deleted off a (no longer working) computer. I have lost all music & data that was on this original itunes. Is there a way I can transfer all content from my iPhone (music & photos) onto iTunes on a new computer? I want to update my iphone (3GS), but do not want to lose any music off it when syncing it. Help please!!

    By design, the iphone will sync itunes content with one computer at a time. Any attempt to sync such content with a second computer will result in ALL itunes content being first erased from your phone & then replaced with the content from the second computer. This is a design feature and cannot be overridden. Because you are using a new computer, your phone will see this computer as a "new" computer. The itunes content sync is one way: computer to phone. If you have photos that were synced to your phone or music ripped on your own that were not backed up, you will first have to extract them from your phone using third party software, before you do anything else, as Apple makes no provision to do so:
    http://www.wideanglesoftware.com/touchcopy/index.php
    Once you've done that, do the following in the order specified:
    1. Disable auto sync when an iPod/iPhone is connected under iTunes>Preferences(under the edit menu if using Windows)>Devices in itunes.
    2. Make sure you have one contact & one event in the supported applications(Address Book & iCal or Outlook, Windows Address Book) on your computer. These entries can be fake, doesn't matter, the important point is that these programs not be empty.
    3. Connect your phone, iTunes running, DO NOT SYNC at this point.
    4. Store>Authorize this computer.
    5. File>Transfer Purchases(To make sure all purchased content on your phone will be in your itunes library).
    6. Right click in the device pane & select reset warnings.
    7. Right click again and select backup.
    8. Right click again & select restore from backup, select the backup you just made. When prompted to create another backup, decline.
    9. This MUST be followed by a sync to restore your itunes content, which you select from the various tabs, You'll get a popup regarding your contacts & calendars asking to merge or replace, select merge.
    You should be good to go.

  • HT2188 i have iphone 3 and when i updated the software my sim card as stopped working, pls what can i do

    i just updated my iphone_3, and my sim card has stopped working, i tried to restore and it kept coming back with erorr mrssage, what can i do

    An iPhone 3G cannot be updated to 5.1.1; the last version supported is 4.2.1. So if you managed to get 5.1.1 on it through some means that bypasses Apple's protections you have wiped out your phone.

    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.

  • My Contracted SIM is for an android phone, but when i put the sim in an iphone my 3g no longer works?..

    My Contracted SIM is for an android phone, but when i put the sim in an iphone my 3g no longer works?.. Is it because my 3g is only active on the android os and not the ios platform? Texts, Calls and Wifi work fine but the 3g doesn't work. My phone only shows 'GPRS' in the top left corner. Also I get a message come up saying "Could not activate mobile data network. You are not subscribed to a mobile data service".
    Any advice would be great.

    Hi hexonxonx, I'm on o2. Thanks for your advice. You are right. All I had to do was change one of my APN settings to mobile.o2.co.uk and reboot my phone and this sorted it out straight away! Thanks again. Much appreciated . I was thinking I was going to have to go back to an android phone to use my 3g again but this eliminated that need. Thanks.

    It has NEVER been possible to purchase an unlocked iPhone 3G in the US. Your phone was hacked. Updating it has re-locked it to AT&T. AT&T will NOT unlock iPhones for any reason.
    The phone is now useless to you. There is no legitimate way to fix this. Buy a new phone. Preferably in India.

  • Why does itunes say my sim card is not supported?

    i have an at&t iphone i just picked up from the apple store yesterday with original at&t sim card that was working until after i restored my phone.  This is the 4th iphone this has happened to in the last month. i wanted to restore my iphone 4 to factory setting so i could set up as new iphone. i put a previous back up on it before. what is going on? a restore should not be rendering the sim reader in the phone useless. yesterday at&t tried 3 different sim cards and they did not work so apple replaced the phone.  the third replacement this month.  now ill have to take this new phone back.  i even tried uninstalling itunes and reinstalling it.  I have a macbook unibody (the last model before it was discontinued) running osx snow lepard

    What is happening is that, as iPhone Warrior said, almost certainly your friend mistakenly purchased an iPhone that is locked to AT&T rather than an unlocked iPhone (which Apple only began selling a short time ago in the US) and then hacked the iPhone to bypass the carrier lock. When you updated iOS on the iPhone, that hack was removed and the iPhone then locked back to AT&T.
    Restoring the iPhone will not fix this problem. Only the carrier could officially unlock the iPhone, and AT&T will not do so for any reason. The only way to use the iPhone again is to hack (jailbreak) it again, and we cannot discuss that in these forums.
    Regards.

  • My iPhone 4s is no longer working.

    My iPhone 4s is no longer working. It kept turning off and on on it's own and i tried to restore it. I pressed the lock and home button. I connected it to itunes as it says. Once in itunes it says the iPhone is on recovery mode and then when it is suppose to restore it says :Verifling with apple and connecting to iphone. Then another screen pops but that an unknown error has happened and doesn't recovery it. What can I do?

    It has no serial number or nothing.

  • Help please - itunes doesnt read SIM card

    Lately my iphone shuts down by itself when i turn it on
    On the screen it says “Activate iphone connect to itunes”
    So I connect it to itunes and a window pops up saying
    “The phone “iPhone” cannot be used with iTunes because the SIM card is not installed. You must insert your SIM card into your iPhone in order to activate it.”
    My SIM card is inserted into my iPhone but does not connect to itunes [i have the recent version]
    I cant do anything in my phone or in itunes
    I went to the apple store and they replaced the phone already for a couple of times [problem keeps happening]
    So one of the people in apple told be to get a new SIM card because that might be the problem [since this problem keeps happening with the same SIM card but different phones]
    Today I bought a new SIM card went to the apple store, they gave me a new iphone, they said it should be able to work
    I came home again the problem happened
    I need help my phone doesn’t work at all and it keeps happening

    Hey BeatrizG,
    If your seeing the issue with multiple iPhones and SIM cards, its most likely an external source causing the issue.
    Do you have a protective case on the iPhone? If the case has a magnetic clip that could be the cause of the issue.
