Update your Apple Pay information
Even if you're trying to download a free app on the App Store, Apple requires that you have a payment method on file registered for your Apple ID. This is primarily for verification and security purposes and to confirm that you're a real user.
If you're seeing this message while trying to subscribe: "Your payment method is not valid at this store. Please add a new payment method." This happens when your credit card's country does not match your Apple ID's region.
Confirm that all the info associated with your card is correct, such as name, address, and CVC. If it's correct, try to re-add the card. Submit documents to verify, if it's available.
If you've confirmed everything looks correct and your payment still won't go through, contact your bank to investigate the issue before you retry payment. In the meantime, you can try your purchase using a different payment method.
