How to use a PlayStation Store card for PlayStation Plus, and how automatic renewal uses your wallet.
PlayStation Plus can be paid with funds in your PlayStation wallet. Add funds with a PlayStation Store card for your account's region, then buy or renew the plan.
If automatic renewal is on, PlayStation tries to take the renewal price from your wallet first. If the wallet does not have enough, it may use a saved payment method or the renewal can fail. Check your subscription settings.
Top up your wallet a few days before the renewal date to avoid losing access.
