There is no issue with using your indó card to withdraw cash at domestic and international ATMs. However, there may be specific fees associated with it. Indó itself does not impose any charges for withdrawals, but it is the bank operating the ATM that determines whether to apply fees for the transaction.
The maximum withdrawal limit at an ATM is 100,000 ISK within a 24-hour period and 400,000 ISK within a 30-day period.
