Frequently Asked Questions
Why is Microsoft Fabric rejecting my phone number during setup?
Phone verification can fail due to incorrect formatting, network issues with the SMS gateway, or because Microsoft's security policies actively block VoIP (Voice over IP) and virtual phone numbers to prevent spam.
Can I bypass the phone verification step when setting up a Microsoft Fabric account?
No, Microsoft currently requires phone verification for security purposes when activating a Fabric trial or setting up a new account. You must verify using a standard mobile carrier number or request an exception through their support team.
Are VoIP numbers accepted for Microsoft account verification?
Generally, no. Microsoft typically blocks VoIP numbers, prepaid numbers, and internet-based virtual numbers for account verification. If you do not have a standard mobile number, you will need to contact Microsoft Support for manual verification.
