Hello,
Thank you for posting in Microsoft Q&A.
Based on the description, I understand your question is related to verify phone.
If you've used the same phone number to verify multiple accounts, it might be blocked from further verifications. Try using a different phone number. Voice-over-IP (VoIP) numbers are often not accepted for verification. Ensure you're using a standard mobile or landline number.
Double-check that you've selected the correct country code and entered your phone number correctly.
If your phone number has been associated with suspicious activity, it might be blocked. In this case, you might need to contact support for assistance.
Have a nice day.
Best Regards,
Molly
