These directions arre for AT and T phones but other than that would be the same for your carrier.
A PUK (PIN Unlock Key) code is required to unlock SIM cards that have become locked following three successive incorrect PIN entries. If your SIM card becomes locked, you will need to get a PUK code from AT&T to unlock your SIM card.
You can obtain your phone's PUK code from AT&T in one of these ways:
Log in to myAT&T online
Use our Technical Support Chat
Contact Customer Care at 1-800-331-0500
Get Your Phone's PUK Code Online
Go to the Phone/Device page in myAT&T.
From the My Phone/Device screen, select the Unblock SIM Card link under the My Make & Model heading.
The Unblock SIM screen will display your PUK code and will give you instructions for unblocking your SIM Card.
Once you receive your PUK code, you will need to enter it into your phone to set a new PIN code.
Note: If you enter the wrong PUK code 10 times in a row, your SIM card will be invalidated, and you will need to purchase a new SIM Card. The phone will display the following error: "PUK blocked call operator."
