For foreigners, N26 and bunq are the most commonly recommended banks — free, fully English-language, and quick to set up. DKB offers a free debit card with free global ATM withdrawals but requires EU citizenship or German permanent residence and operates only in German. Sparkasse (a traditional branch-based bank network) charges a monthly fee (e.g. ~€6/month for Berliner Sparkasse) and requires an in-person branch visit to open, but is widely trusted and accepted everywhere including for Girocard payments.
