Locked out of phone

Hello John_Pilling, we're here to help unlock your phone's sim card.

When you enable SIM lock, your device asks you to enter a PIN code:

• The default PIN code for an AT&T SIM card is "1111".
• Change the default PIN code for more security.
• After activating SIM lock, you must enter the PIN code if you move the SIM card to another device.
• If you forget your SIM lock PIN code, learn how to get the PIN Unlock Key (PUK) code to unlock your SIM card.

To unlock the SIM card if you have an AT&T PREPAID device:

1. Call 800.901.9878 to get the PUK code.
2. If a Motorola device isn’t currently displaying Enter PUK, enter **05* before entering the PUK code.
3. Enter the eight-digit PUK code in your device.
4. Select OK/Yes.
5. Follow the prompts to create a new PIN code.

If your device displays PUK2 or PUK blocked call operator, then the wrong PUK code was entered 10 or more times in a row. The SIM card is blocked and must be replaced. To replace the blocked SIM card, call 800.901.9878.

Let us know if this helps, and thank you for reaching out to the AT&T Community Forums.
