Foreign ATM Cards Work Fine, But Watch Exchange Rates

Most ATMs here accept foreign Cards without problems, including Wise and Revolut which is very good option. The important thing is when machine asks you about Currency Conversion at the end, you must always decline and choose to be charged in VND instead. The ATM's conversion rate is always worse than your own Bank's rate, so you lose money if you accept it. Just withdraw VND directly and let your Bank handle the conversion, you get much better Deal that way.
