Unfortunately we are unable to offer free credits apart from $200 new account offer. One workaround is to create an account under a different email to get the $200 credits. We apologize for the inconvenience!
2. Regardless of your answer to #1, for a new Azure account to be approved, you'll need to supply a previously unused credit/debit card and Azure doesn't not permit use of prepaid debit cards which is a deal breaker (but AWS does BTW).
There is a limit of one account with 12 months free access to products and $200 credits, therefore, our only suggestion is to create a new account with a different email address and credit card; otherwise, you would need to use your existing account and look into the 25+ other services that are always free with your existing one.
