How to update payment information

Hi Fausta145,

Here is the Apple Support steps to update Apple ID payment methods using an iPhone. I also provided some Apple Support links below.

How to change your payment method on your iPhone, iPad, or iPod touch

1. Open the Settings app. 
2. Tap your name.
3. Tap Payment & Shipping. You might be asked to sign in with your Apple ID.

• • 
  • To add a payment method, tap Add Payment Method. 
  • To update a payment method, tap the payment method, then edit your information. You might need to enter the security code that's printed on your credit or debit card. If you see Apple Pay after the last 4 digits of the card number, go to the Wallet app to edit the card information.
  • To remove a payment method, tap Edit, then tap the Delete button. 
  • To change the order of your payment methods, tap Edit, then use the move order icon .*

*Apple will attempt to charge payment methods in order from top to bottom. You can't change the order in which Apple ID balance is charged.

This is a great Apple Support page that answers a lot of Apple ID Billing/Subscription questions: https://support.apple.com/billing. Your question is in the first section.

If you want to skip straight to Apple Support for Change, add, or remove Apple ID payment methods:

If you use family sharing and are not the "organizer" you will run into issues. Send the family organizer this support page which will link them to updating payment methods. https://support.apple.com/en-us/HT201079

I hope you find this helpful,
