Buy prepaid credits without a credit card

Hi I want to use’s free tier for some non-profit, hobby projects.
Unfortunately I do not own a credit card. And credit cards are not as common in my country like they are in the US.
I understand I can use the free tier if I have some credits, but I also cannot buy them without a credit card. Is it possible to use paypal to buy credits?

Hey there!
The best way to buy those prepaid credits would be to get a prepaid debit card (or if you use a bank card!) and then use that to buy the credits. Hope this helps!

Thanks zee for your suggestion,
but on the buy credits page I only see credit card options.
And I don’t wanna get a prepaid debit card just for trying out the free tier.
