How to Find O2 PUK Code and Pin Code

If you haven’t locked your SIM using the O2 Pin code and O2 PUK code then a great risk is hovering over your head! Most people have linked their Facebook or other social IDs with their SIM numbers and anyone can easily hack those IDs. They just have to remove your SIM from your mobile, enter it into a new mobile and get a one-time code from Facebook. Moreover, thieves are also using stolen SIMs for criminal purposes.

But you don’t need to panic because O2 provides its users with a SIM lock feature to protect your SIM from unauthorized use. You just need your O2 Pin code and O2 PUK code. I’m sure you’re wondering what these two codes are. Let us tell you!

In this guide, you will find about O2 Pin codes and O2 PUK codes and how you can access them if you have forgotten them. And we’ll also look at different FAQs regarding these codes.

What Are O2 PUK Code and O2 Pin Code?

What is the O2 PIN code?

O2 PIN code is a 4-digit code that is needed to unlock the SIM whenever it is inserted into a new mobile or the mobile is restarted or restored. The default O2 PIN code is either “0000” or “1234” but it can be some other number also. You can find the O2 Pin code written on the SIM card package.

How to Change the Default O2 Code?

I’m sure you’re wondering how to change the default 02 code. That’s why here’s a step-by-step guide on how to change the O2 Pin code:

Step 1. On your iPhone, go to “Setting > Phone > SIM PIN” and turn on the SIM lock by sliding the toggle to ON and entering the default O2 Pin code.

But if you have an Android phone, go to “Settings > Security > SIM Card Lock” and turn on the SIM lock by turning on the toggle and entering the default O2 Pin code.

Step 2. Tap the “Change Pin” option and press “Done” after entering the current O2 Pin code (The remaining process is the same for both iPhone and Android devices.)

Step 3. Now enter the four-digit number you want to use as your O2 Pin code (preferably not your birthday) and press “Done”.

Step 4. The device will ask to confirm your new Pin. So, re-enter your new O2 Pin code and press “Done”.

Now your Pin has been changed, and you need to enter this new Pin code whenever you restart your phone or enter the SIM in a different phone.

But what if you forget the O2 Pin code and enter the wrong pin many times? That’s when your sim will be blocked, and you will need the O2 PUK code to unblock it. Now let’s see what the O2 PUK code is!

What Is O2 PUK Code?

O2 PUK (Personal Unblocking Key) code, also known as PUC (Personal Unblocking Code) or NUC (Network Unlocking Code) is an 8-digit SIM-specific code required to unblock the SIM when the wrong O2 pin code has been entered 3-times on the device.

But one thing that should be noted here is that the O2 PUK code is unique to the SIM and it cannot be changed by the user. So make sure to save this code or write it down somewhere safe.
When you enter the PUK code, the service will ask you to create a new O2 Pin code, so enter a new pin code and confirm it to continue.

But the sad news is that if you enter the wrong O2 PUK code 10 times, your SIM will be permanently blocked, and you will need to contact the O2 Customer Care Service.

So, what to do if you have forgotten your O2 PUK code too? Is it over for you now? Of course not! The problem can be easily handled if you know what to do.

Below, we have compiled all the easy and accessible ways to get your lost O2 PUK code.
