Why can't I add a test Visa or Mastercard to Apple Pay on my iPhone for sandbox testing?
I followed all the guidelines for setting up Apple Pay on my iPhone for testing:
- Created a new Apple ID for the sandbox account.
- Added this Apple ID to the Test Accounts (in the Users and Access menu in Apple Developer).
- Added the Apple ID to the Sandbox account on my iPhone.
- Ensured that the Apple Store, Apple ID (Sandbox account), and region on the device are all set to Singapore.
- Restarted my device.
- Opened the Wallet app and attempted to add test cards using the website: Sandbox Testing - Apple Pay - Apple Developer
I also tried to add a card through Settings -> Wallet & Apple Pay.
However, the result is always "Invalid Card." I have spent a lot of time but have not found any solutions. Does anyone have any ideas or solutions for this issue so I can add a test card?
