How can I use my Nigerian card to pay

In Nigeria

• Most credit and debit cards
• Apple Account balance (from adding funds)

Based on your country of residence and country you have selected under your Apple ID --> Payment methods that you can use with your Apple ID - Apple ...

Have you a Debit/Credit card that is issued to you that is valid internationally and is from the same Country / Region as your Apple ID.

I tried funding my Apple account with my card but I keep getting a decline message. The account is opened in the Nigeria region which is the same as the cards. Yet it kept declining.
