Are you the only admin under your O365 tenant? Please try the below:
- Use Microsoft Authenticator App Instead of SMS
If SMS verification is blocked, switching to the Microsoft Authenticator app may bypass the issue. You’ll need to set this up from a device that’s already signed in or through your IT admin. - Ask Your Admin to Unblock MFA in Entra ID
If you’re the admin, or can contact one, go to entra.microsoft.com → Protection → Multifactor authentication → Block/unblock users. From there, the blocked phone number can be reviewed and unblocked with a business justification. - Register a Different Phone Number
If possible, try adding a new phone number to your account via the Microsoft 365 Admin Center. This may require admin access or support from your IT team.
Thank you for your reply.
I tried logon to entra.microsoft.com, but I am facing the same problem that I cannot bypass the SMS check.
No matter which site I try to logon, the SMS screen is always popping up and there is no other way I can reach my account. I am able to change the password, but that is all. I tried contacting the helpdesk (Dutch phone numbers), but without any success. Is there another way I can be in contact with support? I have a business account and the phone numbers online are for private use, so they cannot help me.
