When you enter the wrong PIN for your mobile more than three times, your SIM card will be locked. This prevents anyone trying to guess your PIN. To unlock it, you'll need a PUK code.

You can find your PUK code on the package your SIM card came in.

If you no longer have your SIM packaging, follow the steps in Get your PUK code.

What is a PUK code?

PUK stands for Personal Unlocking Key. You might also see this described as PUC, or Personal Unblocking Code.

Once you have your PUK code, enter your PUK code on your mobile as you would a phone number.

The formula to follow is: * * 05 * PUK code * new PIN * new PIN #

So, on your mobile phone's keypad enter:

star, star, 0, 5, star, 'PUK code', star, '1-8 digit number', star, 'repeat 1-8 digit number', hash

Please note: If an incorrect code is entered too many times, the SIM card will be permanently blocked (between 7-10 attempts depending on handset).
