Which credit card is right for me for online shopping outside India?

I’ve heard people say that they use an SBI credit card. But can I do international online purchases? I’m a student. Is VISA or MASTERCARD a good choice over SBI? Which one do you think I should go for? All I want is to buy things online from India and also from outside of the country.

Bytheway, if you think I should use VISA or MASTERCARD, please mention the exact name of the card. Thanks in advance.
