icloud upgrade not working on my iphone

Hello bbg1578,

Thanks for asking about being directed to the payment method. Monthly subscriptions require a payment method: This article talks about the payment methods you can use and states: Payment methods that you can use with your Apple ID - Apple Support

"To make purchases from the App Store, iTunes Store, or Apple Books, or buy iCloud storage, you need an Apple ID and a valid payment method."

You can change your payment method using the process in this help article: Change, add, or remove Apple ID payment methods - Apple Support

This article has things to check if a payment method is declined: If your payment method is declined in the App Store or iTunes Store - Apple Support

If necessary, use a computer and internet browser and undated your Apple ID payment info at Apple ID - Apple.com

Thanks.
