Hello Marcelo Herdy,

To resolve issues related to phone validation during the Azure account creation process, we recommend the following steps:

Try Using a Mobile Device: Some customers have resolved their issues by trying the same process from a smartphone browser. If you haven't already, consider using your mobile device to see if that helps.

Check Phone Number Requirements: Ensure that the phone number you are using for verification meets the necessary requirements. Note that Voice-over-IP (VolP) numbers cannot be used for this process. Make sure your phone can receive calls or SMS messages from a United States-based number, and double-check the phone number you entered, including the correct country code.

Troubleshooting Resources: For detailed troubleshooting steps, please refer to this guide: https://learn.microsoft.com/en-us/azure/cost-management-billing/troubleshoot-subscription/troubleshoot-azure-sign-up

If the above steps didn't help you, I can help you out engaging Azure Subscription/Account review team via a support ticket to unblock your number.

To proceed, I will need a few details from you. As this information contains Personally Identifiable Information (PII), please share the following details via private message:

Contact email address

Attached an error screenshot.

Please send me the detail via private message.

We can then connect offline to discuss further and assist you in resolving this issue.
