Can I register in Google cloud and Amazon cloud without credit card for free trial? [closed]

I want to register on the site for free trial, but as I have seen, they want from me a credit card, unfortunately I do not have a credit card (because the conditions of my country to obtain it are impossible), is there another way to register without credit card ?

So far as I know You can get a prepaid virtual credit card and register for AWS cloud
But for the Google cloud you will need a original credit card. These prepaid credit cards wont work

Just in case: if you are affiliated with a public research institute, you can indeed register without a credit card. See section 2.4 in of the AWS Research Cloud Program handbook version 1.2.
