Click on ‘Become a Viking’ and select the second option 'I want a new mobile number’. Log in to your Viking account or create a new account and then enter your address information. When the registration is complete, your order will be confirmed by email. A € 15 activation fee is charged for this SIM card. This covers the costs of the SIM card and the new number. This amount will not be converted into calling credit (prepaid SIM card) or your first monthly bundle (subscription).
