This blog addresses the question of what is a PUK code are, why you should never lose yours, and how to use them properly if you ever find yourself locked out of the phone.

What is a PUK Code?

When a SIM card is rejected after several attempts to enter the correct PIN code, the SIM card can be released with a special eight-digit number called a Personal Unblocking Key (PUK). The mobile network provider allocates a unique PUK code to every SIM card out there. The PUK code is a security protocol that shields the card even if the person carrying the SIM locking equipment possesses the physical mobile device.

Why Do You Need a PUK Code?

A PUK code is called for when the SIM card’s PIN is entered incorrectly several times usually three times. There are several possible reasons for this code to be entered – you may have forgotten your PIN, you hit the wrong buttons by mistake, or someone else tried to use your mobile phone. This leads to SIM card locking, where you cannot use the card for any activity like browsing, texting or making a call. You will have to input the correct PUK code to regain access again.

How to Find Your PUK Code?

Nobody wants to lose their precious SIM card and the good news is, it is easy to find the PUK code if you know where to look. Here are some of the most effective ways how to find your PUK code.

• SIM Card Packaging: This is because when you first purchase your SIM card it may come in a small holder or is connected to another larger card. It is common to see the PUK code written on this packaging. If it’s still with you, chances are it may be written on the card itself, or on any documentation that came with it, and this is the PUK code.
• Mobile Internet Service Provider: This code can be obtained from your service provider of mobile network operators. Customers can communicate with them through a phone call, social media or even on a mobile application. They will ask you some questions like whether you are the rightful owner of the SIM card that is on offer therefore be ready with your identification.
• Online Account: A large number of mobile network operators provide the so-called ‘online account management’. The PUK code is usually relevant to security or SIM card settings each time you access your account at their website or relevant mobile application.
• Customer Service Centers: It can be more insightful if you visit the establishment offering mobile networks’ physical stores or customer service centres. After the confirmation of the identification of the owner, the employees help retrieve the PUK code.

How to Use a PUK Code?

To unlock your SIM card it is quite easy when you have the PUK code at your disposal. Here’s a detailed guide.

• Enter the PUK Code: Simply, type in 8 digit PUK code that is displayed to you carefully as asked for. Be careful while entering the wrong PUK code multiple times as it leads to a permanent SIM card blockade.
• Create a New PIN: If you manage to input the PUK code as a code that will be required to unlock the SIM card then you will be required to input a new PIN. Do not prefer using general PINS such as 1234 or 0000 and instead prefer using a secure number that is easy to remember.
• Verify the updated PIN: Re-enter the new PIN in order to confirm it. Following that, your SIM card will be unlocked and you can then continue to use your phone as you have been.

What if the wrong code is input after the PUK code has been entered?

In entering the PUK code the information should be well keyed in because it’s sensitive information. Usually, you are given ten tries, or a certain number of tries, in which to enter the correct PUK code. You are even in danger of having your SIM card locked permanently if you exceed this amount. In this case, to obtain a new SIM card the following steps will be followed, and that involves contacting the service provider.
