Simkaart is geblokkeerd (ENG)

Hi Yasuhiro, 

What do you mean by blocked? Have you entered your pin code wrong and is it now asking for a puk code? Or something else?

My kids entered the wrong pin code and the SIM card is asking for a PUK code.

You can find your puk by filling in this form. Let me know how it goes. 

Thank you for you reply. I put my number but the response is;

Het mobiele telefoonnummer is onbekend. Controleer de gegevens en probeer het opnieuw.

How can I proceed it?

Would/could you please call us? 0800 0402 or 06 1200 1200? 

My colleagues over there will be happy to take care of this. 

Thank you! Your colleagues solved this problem on the phone:)
