These situations may lead to payment failure:
-
Invalid or Declined Payment Method: Credit card not enabled for international/online transactions, insufficient balance, expired card, or bank blocking the transaction (such as overseas transactions or small payments).
-
App Malfunction or Process Interrupted: If the app is outdated, you're experiencing login issues, or your network connection is unstable, the transaction may fail, or the payment process may not complete successfully.
-
Platform Region Restrictions: Apple or Google will display different payment options based on your account nationality and region. Some payment methods, such as carrier billing and gift cards, are only supported in specific countries or regions.
