If steps 1 and 2 don't resolve the problem, your user account may be blocked from using Azure AD MFA.
Ask another global admin to confirm whether your phone numbers are set correctly in your user settings. Also, make sure that your phone numbers are correct in your user account settings. If you have set up other options for security verification, select Other verification options, and then try again by selecting a different option. In this scenario, you can't sign in to your work or school account, such as Office 365, Azure, or Microsoft Intune. You don't receive the text message or voice call that contains your verification code. You're a global admin who has Microsoft Azure AD Multi-Factor Authentication (MFA) enabled.
