Hi Raphael,
Thank you for posting in the Q&A Forums.
Ensure that your mobile phone's network connection is working, try switching to another network or using a Wi-Fi connection.
Check your phone's signal strength to make sure it's good.
Check the phone settings:
Check the SMS blocking or filtering feature to ensure that captcha text messages sent by Microsoft are not misdiagnosed as spam.
Clear the SMS storage to make sure there is enough space to receive new text messages.
Check Microsoft account settings:
Log in to your Microsoft account and check that the bound mobile phone number is correct.
Check the security settings of the account to make sure there are no settings to block the reception of SMS verification codes.
Contact the operator:
If none of the above steps resolves the issue, we recommend contacting your mobile phone operator to confirm if there are any service interruptions or settings for receiving specific types of SMS.
Best regards
NeuviJ
