Fix Microsoft Account Locked Unable to Receive SMS Security Code
Question details
The user needs to recover a locked Microsoft account but is unable to proceed because the system fails to deliver SMS security codes to any entered phone number.
- Product
- Microsoft Account
- Device & OS
- not provided
- Scenario
- Attempting to unlock an account suspended for suspected policy violations using phone verification.
- Observed behavior
- Microsoft fails to send security codes via text message to any phone numbers, preventing the user from completing the automated account recovery process.
Ensure you have access to a different, active email address and a stable internet connection so you can create a temporary Microsoft account to reach out to the support team.
Contact Microsoft Support Using an Alternate Account
Since the automated SMS recovery is failing, reaching out to a live support agent using a different Microsoft account is the most effective way to resolve the block.
When the automated security code system blocks SMS delivery, further attempts may flag the account even more. To resolve this, you must bypass the automated system by speaking directly with a Microsoft representative. Since you cannot log in to your blocked account, you will need to create and use a temporary Microsoft account to access the support portal.
Visit the Microsoft account creation page and register for a new account using another email address. You will use this solely to communicate with support.
Sign in to your newly created Microsoft account in a web browser and navigate to the official Microsoft Support Contact Us page.
On the support page, click on 'Microsoft 365' and then select the 'Get Home Support' option.
In the search box provided, type 'Account blocked' and select the most relevant suggestion from the dropdown list.
Scroll down to the bottom of the page and click the 'Contact Support' button. Provide the requested details regarding your blocked account, and click 'Chat with a support agent in your browser' to start the recovery process.

Frequently Asked Questions
Why is Microsoft not sending the SMS security code to my phone?
This can happen due to network carrier blocking, regional SMS delivery issues, exceeding the daily limit of verification attempts, or Microsoft's automated security systems temporarily restricting SMS delivery to certain numbers to prevent spam.
Can I unlock my Microsoft account without a phone number?
Yes, if you previously set up alternative recovery methods like a secondary email address or an authenticator app, you can use those. If no other methods are available, you must contact Microsoft Support directly through another account.
How long does a Microsoft account stay locked?
Temporary blocks usually last 24 hours. However, if the account was locked due to a suspected Terms of Service violation, it may remain suspended indefinitely until you successfully verify your identity via the recovery form or through a live support agent.
