ONE WORD: PERFECT
N26 is now my main account, 
I have been using N26 since 2019 and I sill have the German IBAN. Not a big problem, I have managed to get my salary on so I'm more than happy. It costs nothing and it's perfect when u go abroad (it worked amazingly when I have been to South Africa). The costumer service is amazing and the operators are very kind. No bureocracy issues (problems I had with other Banks) and that's honestly what I was looking for. It's pretty amazing. 

Thank you from a very satisfied client ✌️✌️
