Add a payment method to your Apple ID – Apple Support (UK)
- If you want to change your card, add first the new card, then remove the old one.
- or if you use your Apple ID balance, set your Apple ID balance as your default payment.
You can have a credit card / debit card on file and an Apple Account balance.
If you have set your Apple Account balance as your default payment method, your default payment method will be used first by Apple when you need to make a payment.
Some purchases might require you to have a credit card on file, even if you use your Apple Account balance to make the purchase.
