How to Remove a Number from the Blacklist on Xiaomi Phone: The Complete 2026 Guide

Why Xiaomi Phone Blocks Numbers and How to Fix It

The blacklist on Xiaomi smartphones is a built-in MIUI feature that automatically filters out unwanted calls and SMS. However, sometimes useful contacts get blocked by mistake: due to a system failure, an erroneous addition by the user or aggressive security settings. For example, after updating the firmware, some owners of Redmi Note 12 or POCO X5 complain that important numbers stopped passing, although no one specifically blocked them.

In this article, we will discuss all the current ways to remove a number from the blacklist on Xiaomi, including hidden MIUI 14/15 settings and workarounds for older models.

⚠️ Important: if the number is blocked not by you, but by the operator (for example, due to a complaint about spam), you need to request unlocking through the MTS support service, Beeline or MegaFon.

Method 1: Delete via the standard "Black List" menu

The easiest method is to use the built-in lock menu in MIUI. It works on all models, from the Redmi 9 to the flagship Xiaomi 14 Ultra.

1. Open the Phone app (the tube icon on the home screen).
2. Click on the three dots in the upper right corner → select Settings.
3. Go to the section "Block numbers" (or "Black list" in old versions).
4. Find the blocked number in the list and swipe it to the left (or click on the basket).
5. Confirm removal by pressing OK.

If the number doesn’t appear in the list, check the Lock Log tab – sometimes contacts get there automatically after the MIUI update.

Method 2: Unlock through MIUI security settings

In some versions of MIUI (e.g., POCO F5 or Redmi K60), the blacklist is duplicated in the security menu, which involves integrating the lock function into the system antivirus, to remove the number from there:

1. Open Settings → Applications → Application Management.
2. Find the Security app (the shield icon) and open it.
3. Go to the section “Call Blocking” or “Spam Protection”.
4. In the list of blocked numbers, find the desired one and click on it.
5. Select Unblock or swipe the record to the left.

⚠️ Note: If there are no locked numbers in this menu, but calls still don’t go through, the problem may be in a cloud blacklist (see Method 4).

Method 3: Through the call log (for hidden locks)

Sometimes MIUI blocks silent numbers without adding them to a blacklist, which happens when Auto-Block Spam is enabled or strict filtering rules are set in place to find and unlock such numbers:

1. Open the call log (the Last tab in the Phone app).
2. Find a missed call from a locked number (it will be marked with a red exclamation point or the words Blocked).
3. Click on the number → select Unblock or Add to Contacts.
4. If you do not have an option, click Details → Remove from the blacklist.

On Xiaomi 13T and later, this method only works if the number has tried to reach at least once. If there have been no calls, use Method 5 (via the engineering menu).

Method 4: Cloud blacklist (synchronization with Mi Account)

If you use a Xiaomi (Mi Account) account, the blacklist can sync to the cloud, meaning that the number will be locked on all your devices (e.g., Redmi Pad and Xiaomi Watch S3 at the same time) to remove it from there:

1. Open the Settings. → Accounts. → Mi Account.
2. Go to Data Synchronization → Blacklist.
3. Find the number and delete it (confirmation may be required). SMS).
4. Update the list on your phone by restarting the Phone app.

⚠️ Note: if the number was blocked through Google Contacts (for example, on the previous Android smartphone), it must be unlocked there:

1. Open contacts.google.com.
2. Find a contact. → More. → Unlock.

Settings → Applications → Application Management → Contacts → Clear the cache

Method 5: Engineering menu (for power users)

On some models (e.g. Redmi K50 or Xiaomi 11T), the blacklist is managed through an engineering menu, which is suitable if standard methods have failed. Use it only if you are sure of your actions - incorrect settings can disrupt the phone.

1. Open the Phone app and enter the code: ##4636###
2. Go to the tab Information about the phone.
3. Scroll down to the Call Blocking (or Call Blocking) section.
4. Find the locked number and delete it (the interface may differ).

If the code doesn’t work, try an alternative:

##83781##

It opens the Personalization menu, where additional lock settings are sometimes hidden.

💡

Engineering menu may not be available on European firmware MIUI EU Because of the limitations of the law, in this case, use ADB-commands (see the following method).

Method 6: Unlocking through ADB (for advanced)

If all previous methods failed, the ADB (Android Debug Bridge) remains, which requires connecting the phone to your computer and enabling USB Debugging, and is relevant for Xiaomi with custom firmware or if the system settings are damaged.

Instructions:

1. Turn on Developer Mode: Settings → About Phone → MIUI version (click 7 times).
2. Activate USB Debugging in Settings → Additional → For developers.
3. Connect your phone to your PC and open the command line (Windows) or the Terminal (Mac/Linux).
4. Enter the command to check the connection: adb devices (should display the serial number of the device).
5. Follow the command to view the blacklist: adb shell content query --uri content://call_log/calls (Look for records with blocked=1).
6. Delete the number by command: adb shell content delete --uri content://call_log/calls --where "number='Phone number'"

⚠️ Attention: misuse ADB If you are not sure, contact Xiaomi Service Center.

Frequent Mistakes and How to Avoid Them

Even after the number is removed from the blacklist, calls may not go through, and here are the typical reasons and solutions:

• 🔄 The cache of the Phone app is not cleaned: Settings → Annexes → Phone. → Clear the cache.
• 📵 Do Not Disturb Mode is enabled: Check Settings → Sound and vibration → Don't disturb.
• 🌐 Operator locks number: Call your operator's hotline (e.g. *111 for MTS).
• 🔒 Blocker App Interferes: Remove or disable third-party anti-spam apps (e.g. Truecaller).
• 📱 Double lock-in in MIUI Check both blacklists (see Method 1 and Method 4).

If the problem persists, try resetting your network settings: Settings → SIM-maps and mobile networks → Resetting network settings.

This will remove all stored Wi-Fi networks and cellular settings, but often helps with lockdown glitch.
