Hi, I'm John! I will help you with this.
Microsoft Q&A is public, and we can only provide information. It is beyond our capability to assist directly with the account or login-related issues.
May I know what troubleshooting steps have you already taken?
If you haven't tried anything yet please start by:
- Make sure the phone number linked to your account is still active, has signal, and can receive text messages. You might want to ask someone to send a test text just to confirm it’s working.
- Try toggling Airplane mode On and Off on your phone. This can help refresh your SIM’s connection to the network/tower.
- For more troubleshooting steps, please see "Troubleshooting verification code issues see" https://support.microsoft.com/account-billing/troubleshooting-verification-code-issues-409090c4-92b5-42b9-8ae6-bcc97e62fc48
