Siirto is a mobile payment method provided by Nordea. It works with the following banks:
The Siirto service must first be activated through your bank. You can find instructions for setting up Siirto with Nordea here and for Osuuspankki here.
Afterward, ensure from the Siirto or OP-Mobile app that your phone number is written exactly the same way as on your gaming account (including the country code +358).
As with all other withdrawal methods, you must use your own personal account.
