S****cenario: I am trying to add a mobile number from the Philippines (+63) as an alias or for security verification on my personal Microsoft account.

Result: When I enter my 10-digit mobile number, I receive a red error message: "We don't support that country code. Use an email instead."

Troubleshooting efforts: I have verified that the Philippines is selected in the dropdown menu and ensured I am not adding a leading "0" after the country code. I have also tried clearing my browser cache and using a different browser (Edge and Chrome), but the issue persists.

Goal: How can I successfully add my Philippine mobile number for account verification?
