Buy Ps Plus without a payment method?

My mother bought me a 10 euro PSN credit card and I want to get 1 month Ps Plus with it, but they want a payment method?! Can't you get it without it?

If it doesn't work now, it leaves the menu.

Enter the credit as the payment method

They want credit card or PayPal🤔🙁

You have to go to "Enter code" in the PS store. Somehow that's what it means. There you enter the code and the package that has been purchased will appear.

Ok then I don't know anymore, usually you buy a month directly in the shop

As far as I know you can't buy PS Plus with PSN credits.

This is the age check…

Credit card only works. So yes. Enter the data in advance. There's no other way. Unless you buy a PS + card at the gas station.

I got it…

Yup
