The important thing to do, is to know what flag your card belongs. What I realized in my trips was the ATM machines don't cares about the bank or country of your card. The flag is important. If the flag belongs to Visa or Mastercard, being assured that even most of ATM Machines will accept this.
This is important also to discover if the bank that has emitted your card has agreement with other banks around the world. This implies on: if you can't withdraw your money on any in ATM Machine, you can do it on a bank that has agreement with yours.
But don't carry all your money in your card. For you own safe, it's important to carry some amount in cash. That prevent you both in case of lost of your card and in case of you can't withdraw your money in an ATM machine.
I hope this can help you.
