How To Unlock PUK Blocked Sim Card For MTN, Airtel, Glo, And 9Mobile

If you have a SIM card PIN enabled on your phone to access data on the SIM card, but you repeatedly enter it incorrectly, the SIM card may lock you out from further attempts. You can reset the SIM card, using what’s called a personal unlock code, or PUK code, which you can usually obtain from your phone carrier.
In today’s article, we’ll be sharing tips on how to get a PUK code to unlock your SIM card on Airtel, Glo, MTN, and 9mobile networks in Nigeria.
If you enter the wrong SIM card PIN repeatedly, your SIM card will lock as an added security measure. This prevents someone from simply guessing every possible PIN to access your data if they steal your phone or SIM card.
Once the SIM card is locked, you will need to use a separate code called a PUK code to unlock it. Your carrier can provide you with the PUK code for your SIM card. You can sometimes find this on your carrier’s website after you log in, and you can usually also obtain it by calling customer service or taking the phone to a carrier store. Once you have the PUK code, you can enter it and reset your SIM PIN to the one you know.
Get the PUK code from the SIM card packaging: When you purchase a SIM card, it comes in a little package, and the PUK code should also be included in it. If you still have the package, look for the plastic card that the SIM was snapped out of. The 8-digit PUK code should be printed on the back, together with the SIM PIN code.
