Consult the PIN and PUK
To use your SIM card, you'll need a four-digit PIN code.
If you enter the wrong PIN three times, your card will be blocked and you'll need an eight-digit PUK code to unblock it. Be careful, though: if you enter the PUK code incorrectly ten times, your SIM card will be blocked permanently. You can't change the PUK code, but you can choose your own PIN.
Forgot your PIN code?
- Enter the wrong code three times;
- Enter the PUK code;
- Enter your new PIN.
You can find your original PIN and PUK codes on the NOS App or Customer Area, or on the card that held your SIM.
