Why is my card continuing to deny when I try to upgrade my storage?
All my card info is correct but still doesn’t let me..
Accepted payment methods for iCloud storage upgrades include credit cards, debit cards, and iTunes Store credit. If you don't have enough iTunes store credit to complete your upgrade, you'll be charged the remaining amount. Apple Store gift cards aren't accepted as payment for upgrading iCloud storage.
