I also want to try Azure, but I only have a prepaid credit card (I live in Europe, don't need it except for small Internet things) and Azure is the ONLY service that doesn't accept it. AWS, Google Cloud, Netflix, etc. all work fine, except Azure.

Took me days to figure that one out, because I only got a generic "Your credit card isn't valid" error message when signing up.
