How do I purchase the 50 GB iCloud storage with my Visa credit card. I tried twice and it offered no way to enter a card number.
iPad Pro 12.9-inch, 3rd Gen, Wi-Fi
You need to add that card to your AppleID so it is the default payment method for your AppleID. See -> Change, add, or remove Apple ID payment methods - Apple Support
Then subscribe to iCloud+ storage -> Upgrade to iCloud+ - Apple Support
