Navigate to the official Azure Help and Support portal on the Microsoft website.
Select the option to 'Create a support request' and choose 'Subscription management' or 'Billing' as your issue type.
In the details section, clearly state that your phone number failed the security validation during the free subscription signup process.

Frequently Asked Questions
Why is Azure rejecting my phone number during the free trial signup?
Azure typically rejects phone numbers if they are identified as VoIP (Voice over IP) numbers, virtual numbers, prepaid numbers, or if the country code does not match the region selected for your Microsoft account. Using a standard mobile or landline number usually resolves this.
Can I create an Azure free account without a phone number?
No, Microsoft strictly requires identity verification via a valid phone number and a credit card to create an Azure free account. This policy is in place to prevent spam and fraud.
How long does it take for Azure support to fix the validation issue?
Support response times can vary depending on your region and ticket volume, but billing and subscription support requests for account creation are typically addressed within 24 to 48 hours.
