Use Curve with a debit card with 0% FX markup as underlying card and set the card’s currency to the local currency. That gives you 10 free ATM withdrawals per month. Initially, the daily limit is £200 but after you’ve used Curve for a while it will be raised to £1000.
I can confirm this works with Revolut as underlying card. Revolut sees the withdrawal as an online purchase. Should work with N26 too.
