We've won a Microsoft Azure sponsorship offer/grant for 12 month recently and are now trying to get a subscription for Data + Storage // SQL Database. As far as we understand, the subscription is supposed to be free for us, as we have this grant. But the system asks us to fill in credit card details, and there seems to be no way to skip this step. Do we really have to provide credit card information? If yes, will the subscription actually be free? And if the credit card info is required, then who should be the cardholder according to the existing rules? Should the card be registered to the scientific supervisor of the project (as a person) or to the university (as an institution), or it does not make difference and we can choose to do it either way?
