I used several virtual cards before and I think they all have issues working on websites like Paypal, Aliexpress, etc. (with few exceptions).
I don't know about PayPal but in the case of AliExpress, I have never had issues when using pyypl virtual MasterCard when making payments. However recently they had some legal problems and switched from Mastercard to Visa, I don't know if they will remain the same as they were before.
How about their virtual card do they work worldwide?
I think they do work worldwide for now until they don't. The cards however work for specific services and also have "virtual location" so you will need to pick your preferred card
Once you log in, you will see about 4 different cards to pick from for a start.
