To activate your Blocked Account you will need to submit the document with your Current Bank Account details necessary for the monthly transfers of funds from the Blocked Account. For these purposes, you can create an account in any of the German banks. If you already have a German bank account (which is set up in your name), you can use it for Blocked Account activation.
If you do not have any bank account in Germany and want to set it up in advance to avoid the bureaucratic processes later, our recommendation would be to use Monese. Monese is an online bank that allows you to create a Current Bank Account for Germany even before your arrival and just activate it later when you need it. By choosing Monese account you receive free contactless worldwide accepted Mastercard, customer support in 10 languages, opportunity to pay with Apple & Google Pay and much more.
