It seems you are experiencing issues with receiving SMS codes for Microsoft Rewards. Here are some troubleshooting steps you can try:
- Check Phone Number: Make sure that the phone number you have added is correct, including the country code. Since you mentioned using a Vietnamese number, ensure that it is formatted correctly.
- Service Availability: Verify that SMS services are available for your region. Some regions may have limitations on SMS delivery.
- Blocked Numbers: Check if your phone has any blocked numbers that might prevent receiving messages from Microsoft.
- Alternative Methods: If SMS is not working, consider using other authentication methods if available, such as the Microsoft Authenticator app.
- Retry After Some Time: If you have attempted multiple times, there may be a temporary limit on verification attempts. Wait a while before trying again.
- Contact Support: Since you have already contacted Microsoft Support, you may want to follow up with them, providing them with details of your attempts and the specific error messages you are encountering.
If the issue persists, it may be beneficial to try a different phone number that can receive SMS messages.
