Question details

The user is unable to receive SMS recovery codes to unlock their Microsoft account, encountering an error stating that the code-sending system is interrupted.

Product: Microsoft Account
Device & OS: not provided
Scenario: Attempting to recover a locked Microsoft account after a password change.
Observed behavior: The system fails to send SMS recovery codes, displaying an interruption error. Furthermore, the account remains locked even after successfully resetting the password via a recovery email.

Before you start

Verify that your phone has a strong cellular signal, confirm that your region or carrier does not block international shortcode SMS messages, and ensure your country code is selected correctly on the verification page.

Solution 1Recommended

Use Alternative Verification Methods and the Recovery Form

Bypass the SMS delivery failure by requesting a code via an alternative recovery email address or by submitting the official Microsoft account recovery form.

When the SMS system experiences outages or regional interruptions, the fastest way to regain access is to use secondary verification methods you previously linked to the account.

Select an alternative verification option

On the account login or verification screen, click 'Show more verification methods' or 'I don't have any of these' to see if you can choose a secondary recovery email address.

Submit the Account Recovery Form

If you cannot use an email or an authenticator app, go to the Microsoft Account Recovery page (account.live.com/acsr). Fill out the form with as much accurate information as possible, including previous passwords and email subjects, to verify your identity without an SMS code.

Recovery Form Limitations: The recovery form cannot be used if you have Two-Step Verification (2FA) turned on. In that case, you must have access to at least two verification methods.

Solution 2

Contact Microsoft Support for Persistent Security Locks

If you successfully reset your password but the account remains locked, you will need to contact the Microsoft Support team for manual intervention.

Frequently Asked Questions

Why am I not receiving the Microsoft verification code text?

This can happen due to carrier blocks on automated shortcodes, poor network coverage, incorrect country code selection, or temporary outages with Microsoft's SMS delivery servers.

Can I unlock my Microsoft account without a phone number?

Yes. You can unlock your account using a previously linked recovery email address, an authenticator app, or by successfully filling out the Microsoft Account Recovery form.

How long does a Microsoft account stay locked?

Temporary locks for unusual sign-in activity may resolve in 24 hours. However, if the account is locked due to suspected security compromises or terms of service violations, it will remain locked until you verify your identity or contact Microsoft Support.

Why is my account still locked after I reset the password?

Resetting a password proves you have access to a recovery method, but it does not always clear security flags. If the system detects ongoing suspicious activity or requires manual review, the lock will persist even with a new password.
