Treat card binding failure as a payment-plan failure, not just an app bug. Check card network, bank travel controls, identity details, SMS access, and a second card before relying on Alipay.
You are adding an overseas bank card to Alipay before your China trip, and the app or bank rejects the card. If you ignore it, your first payment test may happen under pressure after landing.
Do not assume one foreign card represents all cards.
Do not assume card binding means every merchant will accept payment.
Do not assume support can fix bank-side blocks immediately.
