Your PIN code is delivered in one of two ways, depending on your type of SIM card:

– For a physical SIM card: on the plastic card that contained your SIM. Store it somewhere safe, not together with your smartphone.

– For an eSIM: in the same email as your QR code.

If you can’t find your PIN code:

– First check your spam or junk folder. The email sometimes ends up there.

– If the email doesn’t arrive, contact us. We’ll resend your PIN code.

If you enter your PIN code three times incorrectly, your SIM card will be blocked and you’ll need your PUK code to unblock it. You can find your PUK code in the same place as your PIN code, or in our app or My account at https://wsc.undo.be/?lang=en via MORE, then SETTINGS, at the bottom.
