Digital Ocean account problem : Card Does not support this type of purchase

When I click on digital ocean website provided by the course then they directly tell me go through the payment. After I fill the details and click on “Save Payment Method” button I got this error .
“Your Card Does not support this type of purchase.”
What should I do? for creating an account on digital ocean.? Please help me.


Your card may not support the purchase, most likely you need an international card.

We have already provided an alternative in the training, please go through that.

Try in, Master or Visa card

Ok ,Thank you. I will go through the alternative one.
