Should remove the Card Verification when signing up
Azure should remove the Card Verification step when signing up for free trial, this is to be able to proceed to the registration even with or without credit card since this is only for free trial, it will be helpful for students who don't have credit cards whose just using the service for educational purpose.

Registration to Azure free trial should not depend on a credit card as in some countries it's not easy to acquire one. it's frustrating that you are deprived of an opportunity to learn an interesting service like Azure just because you don't have a credit card.
