Which card do you use for international payments?

I love playing games. I have a huge steam library but there are some games which aren't on steam but on Epic Games.

I use SBI debit card, it has similar features like SBI employees. Doesn't work at all.

I want to know does anyone here uses Jupiter or Slice or any other NeoBank for international payments/shopping? Which one's better?

P.S. I am a student so credit cards won't work for me. Not do I plan to use credit cards in my life.
