Hello @hwash9278,

welcome to our o2 Community 😀

It's always very annoying when you can't find your PIN to unlock your smartphone. You can find it on the plastic holder from which the SIM card is removed, or as Vilureef wrote, in our customer online portal.

If neither is possible, your only option is to call our customer service (e.g. the English hotline) or go to an o2 shop near you.

Have you maybe already received the PIN? If you still have any questions, please let us know.

Best regards

Giulia
