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.
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.
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!
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.
The first method by which you can get access to your O2 PUK code and O2 Pin code is to look at the SIM card package. When a new sim is bought, these codes are provided by the mobile operators on the plastic card the SIM is attached to. So, just look for it there and enter it on your mobile to access all the services the mobile operators provide.
But SIM card Package is not something that most people keep safe. So if you have lost your SIM card package, there’s no need to fret, because another way to get the O2 PUK code is through the mobile operator’s website. Let’s see how to do it!
If you are an O2 user, then you must have made your My O2 account. Here are the steps to get the O2 PUK code from the website using My O2 account:
You can also get the O2 PUK code from the My O2 mobile App by following the same process. But if you haven’t made your My O2 account, then don’t worry! We’ve still got you covered.
You can get your O2 PUK code from the O2 official website most of the time. However, there’s a slight chance that it doesn’t work. So what to do in this case? Just contact the O2 help center and tell them about your problem. After confirming your identity, they will give you the O2 PUK code.
