One card should handle most of your spending abroad without drama. Picking a reliable primary travel card up front reduces friction, protects your money, and keeps payments simple no matter where you land.
When money fails overseas, it’s rarely because your wallet disappears. It’s because your accounts weren’t secured before you left. Lock them down early so access never becomes the problem.
Most banks are great until you leave the country — then they turn into friction machines. Pick one that actually works overseas so your money stays available when you need it, not when the app feels like cooperating.
