Almost not possible that you have a Fidor Account without being a permanent German resident.
We have something called "Einwohnermeldebescheinigung" which can be accessed by banks in the "Melderegisterauskunft" (some kind of database).
So this Fidor requirement : "Du musst mindestens 18 Jahre alt sein mit ständigem Wohnsitz in Deutschland. " which is translated "You must be at least 18 years of age and a resident of the Federal Republic of
Germany." is not possible to prove.... .
But even more impossible is this : "Gib bitte für deine Ein- und Auszahlungen eine gültige Bankverbindung und deine Mobiltelefonnummer an. Das Konto muss auf den Namen des Kontoinhabers bei einem inländischen Kreditinstitut geführt sein. "
Which says, that you need a
bank account at a national (german) bank in the name your Fidor account is.
Do you have a German bank account?
I am German and they canceled my account there after knowing that I permanently left Germany as my residence.
However I don't say you are lying. Sometimes mistakes happen and you could have had luck. But it is quite impossible. Congratulations if you really have an account there which didn't get blocked yet. German banks are regulated as f**k.
