All about your PIN code

What's the difference between the PIN and PUK codes?
  • PIN code

You PIN code gives access to your handset. You have to give it in every time you start your phone. When you buy a new SIM card, you receive a PIN code which you can change later. 


Good to know: you get 3 attempts to give in the right PIN code. 3 times wong? Then your handset will block itself as a security mechanism. If this happens, you need your PUK code to unblock it.


  • PUK code 

Your PUK code comes in handy when your handset is blocked (for any reason). The PUK code typically counts more digits than the PIN code.

Frequently asked questions about the PIN code

Looking for your PIN code? There are 2 ways to find it

  • on your SIM card;
  • in My BASE, under "My SIM cards" if you have a physical SIM or eSIM.

Type the following code using the phone function of your smartphone and push call: 

* * 04 * [old PIN code] * [new PIN code] * [new PIN code] #

Tip: Avoid choosing codes that are easy to guess, such as '1111' or your year of birth. This way your handset will be more secure.

Remove your SIM card  from your handset for a moment and then put it back in it. 

Same problem?

Perhaps you already entered an incorrect PUK code 10 times? Then you will get the message 'SIM card rejected'. In this case, it means that we have locked your SIM card in order to protect your handset and your personal data.

This also means that your SIM card is not usable anymore. Buy a new SIM card via the My BASE.
