In case of lost or forgotten PIN, the mobile phone will ask you to enter the PUK code (after three incorrect PIN). Just enter the PUK code received with the SIM card. You can then choose a new PIN.
Please note that after 10 incorrect PUK codes throughout the life of the SIM card, the card will be out of order and will require replacement.
In case of loss of the PUK code, please contact our Call Center at +352 671 009 009 or visit one of our shop (find the list, schedules and contacts here).
