No need. You can make transactions and withdrawals from your euro account and your personal account using your existing debit card.
To use your debit card with your euro account, you’ll need to activate “Currency Controls” in the “Card Controls” screen. Otherwise, all card transactions – even those in euros – will continue to be debited from your personal account.
Once you’ve activated “Currency Controls”, euro transactions will come from your euro account, including cash withdrawals. All other currency transactions will continue to come from your personal account. This means that your €100 hotel payment will come out of your euro account, whereas your £9.99 Netflix subscription will be debited from your personal account.
