Howdy all,

Does anyone know what the default SIM PIN is on the iPhone? In the SETTINGS menu under PHONE:SIM PIN, I am trying to turn the SIM PIN on, yet it keeps asking me for a password. It says I have 1 attempt left, so I don't want to enter a code until I am sure I have the right one. I've tried calling Apple and they transfer me to AT&T... and then AT&T transfers me back to Apple... and repeat.

Any suggestions would be greatly appreciated.

Thanks All.

iPhone 8GB, Mac OS X (10.4.10)

    Dont touch it, don't put in any pins, etc.

    ATT/Cingular will lock up your phone if you mess with the sim pins and then you have a paperweight until they unlock it again for you.

    Don't mess.

    I'm sorry, but this isn't true.

    The default PIN for the iPhone is "1111". As is most other Cingular/AT&T phones.

    Even if you do manage to lock the SIM due to 3 failed attempts, call AT&T support to get the PUK code and you can unlock it and change the PIN.

    The whole point of the PIN is to keep someone from stealing your SIM and making a bunch of fraudulent calls charged to your account. Everyone should have their SIM locked.

    Oh, I forget to say,

    APPLE, you need to put this information about the default PIN in the Manual! It's required info. Even AT&T CS didn't know what the default PIN for an iPhone was.

    Any Device specific information can only be provided by APPLE CARE 1-800- MY IPHONE. AT&T only troubleshoots network issues and checking to make sure your Visual Voicemail is setup correctly in their systems. Basically if you wanna know how to use youriPhone, call APPLE!

    You dont have to call AT&T. You can get the PUK unlock code yourself from your account page at the AT&T Wireless page.

    True, but the SIM is an AT&T controlled component, not Apple. If you call AT&T CS about the default PIN, they currently don't know since it's not in the Apple manual. I even raised this up to a director level there. If you call Apple, they tell you call AT&T. No one wants this hot potato...

    The default PIN needs to be put into the User Manual. It's inexcusable to leave it out since inserting the wrong PIN 3 times results in the SIM being blocked and a non-functioning phone until the PUK has been entered or the SIM replaced by AT&T.

    Good info PTBoater. I wish they had the default PIN listed there somewhere so the PUK would be unnecessary.
  • jaystad Level 1 Level 1 (10 points)
    Thank you very much for all of the responses. the default unlock code was indeed '1111'.

    Very much appreciated.

    Yeah, i've been trying all day since last night to access my account and keeps saying to try again later.

    One other question. If you lock the SIM on the iPhone and then want to take that sim out and put it in another phone, do you run into any problems?
  • saudaqeta Level 1 Level 1 (0 points)
    If you put a locked SIM into another GSM phone, you'll be required to enter the PIN in order to use the phone.
