Your physical SIM card is shipped within 1 working day after your order and should normally reach your address within 2 to 4 working days (depending on the courier and your location).

If you haven’t received anything after 5 working days:

– Check that your delivery address is correct in your UNDO account. Open our app or My account at https://wsc.undo.be/?lang=en, go to MORE and SETTINGS.

– Check your mailbox again, and possibly that of close neighbours — UNDO SIM cards are sent in an A5 cardboard envelope.

– If you still receive nothing, contact us. We’ll send you a new SIM card.

Tip to avoid waiting time: choose an eSIM for your next order. An eSIM is delivered immediately by email and is active within the hour.
