How To Unlock PUK Code On MTN, Airtel, Glo & 9Mobile SIM Card

One of the things that could really get you frustrated with your SIM is when your Sim card gets blocked after you incorrectly inputted a wrong SIM PIN thrice. At this juncture, you will be required to provide the SIMs PUK number in order to unlock PUK code on the SIM.


The issue could easily be short-lived if you have the phone numbers SIM pack available. Other than that, the issue could even be more complicated.

Because of the difficulties experienced just to retrieve your PUK code to unlock your SIM card due to wrong PIN attempts, I now decided to make a full guide on how you can easily retrieve your PUK code on all networks (MTN, Airtel, Glo, and 9Mobile).

What Causes Sim Cards to be Blocked?

After undergoing a series of research, I found out that what mostly causes people’s SIM cards to be blocked by their network providers is a result of too many attempts of wrong PINs.


Even though other factors could also constitute the blocking too, incorrect PIN attempts is the most feasible.

How does this happen? Some people usually prefer to lock their SIM cards mostly for security reasons to avoid people from accessing their data in their SIM card.

Now, to enable this PIN on the SIM card one is required to set a four (4) digits number as his or her PIN. Once activated, no one will be able to access sensitive data in the SIM.


As time passes by, the owner of the SIM might forget the security PIN he or she used to lock their SIM card. Now, on the day they are required to provide this PIN inorder to unlock their SIM, since they may have forgotten the PIN they used, they try to guess the PIN.

To avoid abuse, you are only given 3 attempts to unlock your SIM card if it is locked with a PIN.

So after attempting to unlock the SIM with a wrong PIN three times, the SIM card automatically gets blocked by the respective telco company.


The only lifeline for this is to use the SIMs PUK code.

So the big question now is how to get your PUK code so you can unlock or unblock your SIM card particularly if you have misplaced or lost your SIM pack.

Read below to see how to unlock PUK code on your SIM card.


How To Find and Unlock PUK Code On Your SIM Card

The term PUK is an acronym for Personal Unblocking Key. Every SIM card usually comes with its own unique PUK code. The PUK code is usually found written on the SIM pack of the SIM.

So if you have gotten your SIM card blocked and it is requesting a PUK code to unblock it, simply reach out to your SIM pack, check the back of the pack. Depending on the network, the PUK code could either be located at the top, centre, or bottom of the SIM pack.

When you find it, now type in the PUK code correctly to unlock or unblock your SIM card.
