There is nothing more annoying than being thousands of miles from home, and having your credit card company freeze your account, thinking there is fraud going on. Generally speaking, if you use your card away from home to purchase something unless it’s for a considerable amount, it will not raise a flag. However, put your card into an ATM away from home to get even $10 out. Bingo it’s flagged. The best bet is to call the number on the back of your card before you leave home, tell them where, and how long you will be gone. Then everything should be ok.
