Really some virtual cards dont need KYC? Thats great but I think that would be impossible in our place to have stuff like that. Since Government mostly authorize services provided theres KYC.
Unless it is illegal, does it hurt to try? Do some research on whether they are legal in your country and if they are, I do not see why it would get you into any trouble. The biggest risk you assume is having it not work, at which point you lost a few Dollars at most.
