Answer:
A PUK code (Pin Unlock Key) is required when you enter an incorrect PIN 3 times. After entering the wrong PIN 3 times, the card will be locked and you will need to get a PUK code from your service provider to unlock it.

If you have AT&T ;

Sorry to inform you but it sound like your SIM is now locked .. Here is some info to help.

please take the time to review my advice and be kind and leave a feedback rating it helps me too.

You can receive your phone's PUK code from AT&T, either by logging into your account at myWireless Account, visiting our Technical Support Chat, or by calling Customer Care at 1-800-331-0500.

Once your PUK has been received, it will need to be entered into your phone to set a new PIN code.

If the wrong PUK code is entered ten times in a row, the SIM card becomes invalid and you will need to purchase a new SIM Card. The phone will display "PUK blocked call operator".
