Where do I find the PIN and PUK code of my SIM card?

In 'My Viking' you'll find your PIN and PUK code. The default PIN code of your SIM card is 1111.

If you have entered the PIN code incorrectly three times, your device will require your PUK code. You can now use the puk1 code. After entering this PUK code you choose a new PIN code.

Do you want to change the PIN code? You can change it via the settings on your phone. If this function is not available, you can instead form and call the following code:

(*)*04*[old PIN]*[new PIN]*[new PIN]#. Insert this code and press "Call".

(*) for some devices only one * is required before the code.
