My SIM locked after an update

My SIM card for my iPhone 5 locked up after an update just a few minutes ago. Apparently, the right code (which I've used for years) was wrong. Now, I've got to enter the PUK code. What the heck happened?

Yes I know I have to do that, but why should that happen in the first place!

  • SIM locked after upgrade

    I upgrded to an iPhone today. Got it home. Got it working almost perfectly after a little bit of work. iTunes then prompted me to "upgrade" the iPhone's softare, so I said yes. After the update the phone rebooted and said the SIM was locked. Should I have gotten an unlock code when I bought the phone? I'm on t-mobile in Germany.

    In Germany, the iPhone is carrier locked to T-Mobile.

    my phone is locked after software update

    In some cases a reboot by holding both the power and home buttons until the apple logo appears, ignoring the red slider if that appears, has helped.  In more difficult cases it has been necessary to restore via the recovery mode per the instructions in http://support.apple.com/kb/HT1808.

  • How do I know if my iPhone 4 will not get locked after I update to ios5 ?

    How do I know that my iPhone 4 will not be locked once I update to ios5 ?

    Then have your father ask this someone he sended to get the iPhone for you.
    Do you still have the retail sales box?
    If so, is any carrier name or carrier logo available on the rear of the box?
    If so, the iPhone was sold as carrier locked.

  • Unable to read SIM card after latest update

    I downloaded the most recent android update on my Samsung Galaxy Note 4 on 12/10.  Since that update, i've gotten the message "Unable to read the SIM card.  Please restart your phone to read the card" a half-dozen times.  The timing between the messages is sparatic (one time it was a few hours between messages, another time a full day, then 12 hours the third time, etc...).
    Is anyone else experiencing this issue?  Is there a simple fix to this (such as just getting a new SIM card from Verizon)?  I'd like to think that the update wasn't the culprit of this, but I've had my Note 4 since the initial release, and it's only started happening since the last update.
    Any help would be greatly appreciated.  Thanks!

    I'm having the same "Unable to read the SIM card" issue. My phone is less than two months old, the unable to read SIM card issue started about a week after I purchased the phone. That was followed by a host of erratic, sporadic issues to the phone becomes unusable and the only way to temporarily fix it is to remove the battery for a few seconds.  I've gone through the factory reset with Verizon reps where I purchased the phone from as well as with a Verizon online Chat representative. In a nutshell, I got a ticket to send the phone back to Samsung in Plano, Texas to get the phone fixed, I am going to do that today because this problem is ridiculous.

  • Droid DNA - No SIM card after OTA update

    I took the OTA update for the DNA today. Now my phone says it doesn't have a SIM card. Reboot does not solve the problem. Has anyone else experienced this?
    Why can't Verizon properly test updates before unleashing them on its customers?

    I have had the 'No SIM Card' issue before and after the software update, and am beginning to wonder if it's a hardware issue. Last night, I did not have a connection for nearly twenty minutes, and during that time I rebooted (quick power off as well as closing all apps) and turned airplane mode on/off about 20 times. I've had the No SiM card issue for about 3-4 weeks in varying occurrences. I've taken very good care of my phone, haven't dropped it, and haven't done anything to damage it, so I don't know what Verizon is going to do about this, but it's holding me back from updating my data plan and buying expensive accessories like the wireless charger.
    Furthermore, if an emergency situation were to happen while this problem were occurring, I will absolutely hold Verizon responsible for any damages or injury caused by the inability to communicate through 911, etc. 

  • Sim locked after downloading IOS5

    I have a new iphone 4S 32Gb only just got the new sim from Telstra yesterday and it was working, could make calls, texts etc until I downloaded ios5 and synced it with my computer.  Straight away it says 'the sim is locked.  Insert a valid sim with no pin unlock.' How can I unlock it? Or do I have to take it back to Telstra to get a new sim?

    Thanks very much. They were able to unlock it and gave me the code as well.

  • ITunes not recognizing my sim card after iPhone update

    Hi,
    So I just updated my iPhone software to the iOS 4 version on my 3G and connected it to itunes. Everything got backed up fine but when connecting to the itunes store, it says that my sim card is not supported.
    I've tried turning it off and switching it back on, but nothing seems to work.
    If anyone can help me in this, it would be awesome!
    Thanks!

    Are thses actual microSIMs or regular SIMs that have been cut down?
    IF they have been cut down, it's possible they were not cut properly and are not making contact resulting in marginal performance.
    If they are microSIMs then it's possible the iPhone is experiencing a hardware issue.

    If it locked while trying to do an update then you probably have a hacked/jailbroken phone.
    You will have to find help elsewhere as we cannot help you here.

  • Q10 still locked after ad Update.

    Hi, i updated my Blackberry Q10 by OTA.
    Then a configuration process stated at 100%.
    Now, although i reboot the system i cannot start OS.
    It's still on 100% without fluctuations.
    I need help! Thanks in advance.

    How long has it been that way? Is it still that way? If so, you may need to connect to Link and reinstall the OS from scratch.

    The phone was hacked to unlock it. It relocked when you updated. ONLY the carrier it is locked to can authorize unlocking it. If you are not/never were an AT&T customer and you do not have an original store receipt from either an AT&T or Apple store in the U.S. for a no commitment AT&T iPhone, they will NOT unlock it.
    Buy a new phone.
