To unblock your MTN SIM pin you will need to use its PUK number. This will allow you to create a new SIM pin to replace the old one. PUK is short for Pin Unlocking Key, a 10-digit number you can use to unlock a SIM security PIN that has been blocked from entering its pin number. A SIM pin number only allows for three tries, and on the third unsuccessful try, it will be blocked from any more PIN entries.

SIM cards use pin numbers as security measures that prevent unauthorized users from accessing the SIM’s information or using up your airtime and data, especially if inserted into a different device. If you don’t remember your original PIN and it has been changed you can purposefully block your PIN so that you can create another one using your PUK number.

You can get your PUK number that corresponds to your SIM card on the MTN app, SIM pack, or from the MTN SA self-service number.
