The only way to answer this question conclusively is to call the bank which issued the card. There should be a phone number on the back of the card which you can call. You should ask a few key questions:
- Will the card work in your destination country/ies?
- Do you need to inform the bank of your travel plans and dates? (Many banks will notice foreign transactions and trigger an anti-fraud lock on your card if they don't know you're expecting to use your card in a new location, which can be quite annoying)
- Will there be additional transaction fees or exchange rate fees for foreign transactions?
