Common questions
What signals matter most?
Gateway support, local billing rules, Korean phone verification, and whether checkout depends on domestic app authentication.
Is Amex support essential?
No. Visa and Mastercard acceptance is usually the stronger signal for broad foreign-card compatibility.
Can a product page look safe while checkout fails?
Yes. Failure often happens late when the payment gateway or verification step appears.
