Your contactless card can be used overseas wherever the contactless symbol and the Visa logo are displayed. Contactless payment, however, requires a lot of technology and lightning-fast communication between the vendor and the bank. There's a good chance the merchant is at fault if your equipped card isn't working abroad. In spite of the fact that they may tell you they use contactless travel, you may have trouble making purchases. It's good news, though, that your account won't be blocked or penalized if your card doesn't work with contactless purchases.
