I've also asked the support about the virtual card, and they said they currently have no information about it.
I already asked about virtual cards in advcash topic here and got this answer:
Hi, I see advcash updated its card and included ADV Global and ADV Crypto World which is a great move although comparing to Europe, fees are higher. I wonder know why global virtual card wasn't included? and when it will be available? Thanks.
Fees are always higher if you compare internationally available products with EU-only products, this works for basically any such platform. The economics of international USD cards is quite different, and the fees reflect that.
It depends on the card vendor what kinds of cards they offer. These vendors do not have virtual cards at the moment, but if and when they do, we will be happy to consider adding them as well.
Did something change regarding the providers of the cards? Why are more services starting to accept the rest of the world all of a sudden?
There is only few services accepting the rest of the world and AFAIK only advcash released new cards although they launched it in the past then stopped and changed providers before accepting it again.
