What do you mean by "work"? as in the ability to order it from a specific country? or sites you could use it with? If the latter, then I would imagine there will be some restrictions on that but for ordering it, then I don't see why would that be an issue since KYC is not required
What I mean worldwide is that if the virtual card will work for any services like Playstore, Amazon Aws, or any subscription.
It seems not all services and sites will work based on JeromeTash posted above?
