How can I get 1 month of free data via the Mobile Vikings clan?

Easy enough. If you are not a member of a Viking Clan yet, on your Viking birthday (= if you have been a Viking for 1, 2, or x years) you will receive a one-time e-mail invitation from us to form a clan of 2 members with Mobile Vikings for 1 month. 1 click for 1 GB, it's that simple.

PS: You can form a Viking Clan with Mobile Vikings starting from a € 15 subscription. You cannot invite a 3rd or 4th member to your Viking Clan with Mobile Vikings. If you want more free mobile data every month, you can of course create your own Viking Clan after this month and get up to 3 GB per month.
