TERRIBLE. and theft with first deposit
TERRIBLE. Use another banking service!
Having deposited the first amount onto my recently open-end N26 account (via a till in a pound shop... since this was the only way to deposit cash in my vicinity, a district in a capital city, Vienna), I knew N26 would charge a percentage for having done so (something a decent bank would not) but I knew this in advance and despite this being an issue, decided I will give this bank a shot. I set up various domestic standing orders to leave this N26 account. however, three weeks after having deposited the money, I woke up to all of it having disappeared from my account. withdrawn at a cash point halfway across the world. ok, fraud unfortunately can happen. so straight away I contacted N26, was told where to find the links to documents I now needed to complete in order to retrieve my stolen funds. for more than a month I did not receive ANY communication back from N26. 
I contacted the chat assistants three times. one of them particularly incompetent and rude. threatening me with it being just out of courtesy to retrieve my monies. implying I better behave kindly if I wanted the possibility of being refunded the stolen money from N26, despite it being a very evident fraud (due to the geographic of the card use). 
following were various deductions from my N26 account by N26 for having incurred international bank charges and thereby being overdrawn. but still no peep regarding a resolve. or anyone really to acknowledge and confirm the dealing of my case. and the stopping of the persistent N26 charges for being overdrawn. first I was informed I would hear back after 2x weeks. when two weeks arrived I was told it would be 3. after 3 weeks I was told it would be SIX weeks before anyone would get back to me. finally, after 5 weeks someone contacted me and I finally received my money back. 
in the meantime I have had to go to the trouble of opening another bank account (with another bank of course), and canceling/setting up all standing orders again so my bills could go out. 
if you are looking for an "international' bank card, DO opt for another... 
N26 use impolite language when speaking with their customers, patronising at times. 
their banking security precautions definitely appear to be sub-standard.
MONZO is a great alternative, I have used them for years, never a problem. but the grief I went through with N26 - definitely NEVER again.
