    Hello,

    Just to ask, does the phone number shown on the screen match your current mobile number?

    Microsoft sign in security requires verification before account access. If the SMS code does not arrive, you can try these:

    • Check the phone number and country code shown on the screen.

    • Select Send code again after a few minutes. SMS delivery delay occurs with some carriers.

    • Check mobile signal and confirm SMS inbox storage not full.

    • Select another verification option on the page such as email or Microsoft Authenticator if listed.

    • If verification still fails, use the Microsoft account recovery form https://account.live.com/acsr

    so the Microsoft system reviews ownership and restores access.
