Hello @Adrian
When you start using Azure with a free account, you get $200 credit to spend in the first 30 days after you sign up. In addition, you get free monthly amounts of two groups of services: popular services, which are free for 12 months, and more than 40 other services that are free always.
Your credit should be available during the first 30days if you have not spent them all.
I hope this helps.

Yutong
