How to remove a number from the blacklist on Xiaomi: all the ways of 2026

Blocked an important contact on Xiaomi and now you can’t get a call or a message from it? Or accidentally added a number to a blacklist and now you don’t know how to remove it? This problem is familiar to many owners of Redmi, POCO or Mi smartphones – especially after MIUI updates, when the menu interface changes and the old instructions stop working.

In this article, you’ll find 5 current ways to remove a number from the blacklist on Xiaomi, including hidden MIUI 14/15 settings, bypassing locks through Google Contacts, and even recovering deleted records. We’ll take a look at the nuances for different firmware versions and models, from the budget Redmi Note to the flagship Xiaomi 14. And if the standard methods don’t work, we’ll show you how to reset lock settings without losing data.

1. Standard method: through phone settings

The easiest method is to use the built-in MIUI tools. It works on all modern Xiaomi smartphones (including Redmi 12, POCO X5, Mi 11 and later) and does not require installing additional applications.

The following is the case for MIUI 12-15:

• 📱 Open the Phone app (the tube icon on the home screen).
• ⚙️ Click on three dots in the upper right corner → Select Settings.
• 🔍 Scroll down to the section Lock numbers (on some models – Blacklist).
• 📋 Here you'll see all the locked numbers. Click on the contact you want. → Choose Remove from the blacklist.

Check the version of MIUI in Settings → About the phone

Make sure the number is not hidden in the contact archive

Close all background apps (especially messengers)

Backup your contacts through Google Account

-->

If the list does not contain the number you need, but calls from it are blocked anyway, check:

• 📵 List of blocking in messengers (WhatsApp, Telegram, SMS-attachment).
• 🛡️ Third-party anti-spam applications (e.g. Truecaller or Kaspersky).
• 📱 Settings SIM-Cards (sometimes operators block numbers at the network level).

💡

If the number doesn’t appear in the blacklist but calls don’t go through, try adding it to contacts and deleting it again – this sometimes resets hidden locks.

2 Unblocking through Google Contacts (if the number is missing from the list)

Sometimes, after updating MIUI or resetting the settings, the blacklist is cleared, but the lock remains, in which case synchronization with Google Contacts will help – especially if you previously saved numbers to your Google account.

How it works:

1. Open Google Contacts (web version at contacts.google.com or app on your phone).
2. In the menu on the left, select More → Settings → Restore contacts.
3. Specify the date when the number was not blocked (for example, a week ago).
4. Confirm the recovery – it will return all contacts and associated lock settings.

Important: This method will only work if:

• 🔄 You have synchronized your contacts with Google.
• 📅 You remember the approximate date when the number was blacklisted.
• 📱 The phone was not completely reset (in this case, Google data will not help).

3. Hidden MIUI settings: unlock through engineering menu

On some Xiaomi models (especially Redmi with custom firmware), the standard blacklist menu can be hidden or disabled, in which case the engineering menu will help, a special diagnostic mode where you can control locks at a low level.

⚠️ Attention: Incorrect actions in the engineering menu can disrupt the operation of the phone.

Step-by-step:

1. Open the Phone app and type the combination: ##4636## (some models may require #86583###).
2. Select the Phone Information (or Phone Information) section.
3. Scroll down to the Call Blocking block.
4. Here you'll see a list of all the locked numbers. Click on the desired one and select Unblock.

If the engineering menu does not open:

• 🔧 Check if access to it is disabled in the developer settings (Settings) → The phone. → Version. MIUI → Press 7 times to unlock).
• 📱 On some firmware (POCO s MIUI for POCO) Engineering menu hidden – use the app MTK Engineering Mode from Google Play.

4. Use of third-party applications (if standard methods do not work)

If the built-in MIUI tools don't help, you can use third-party applications to manage locks.

• 📵 The number is blocked at the operator level (for example, MegaFon or Beeline provide their own blacklists).
• 🔄 After the firmware update, the standard lock menu disappeared.
• 📱 The phone has an unofficial firmware installed (for example, Xiaomi.eu or LineageOS).

Top.-3 Applications to unlock numbers on Xiaomi:

⚠️ Note: When using third-party applications:

• 🔒 Turn off the built-in lock in MIUI, avoiding conflict.
• 📋 Export lock lists regularly (most apps have Export/Import functionality).
• 🛡️ Check the permissions of the applications – some may request access to the SMS and call logs without need.

5. Reset lock settings (extreme case)

If none of the methods worked, the lock settings will be reset, which will delete all locked numbers and return the default settings, but will not affect personal data (photos, messages, apps).

How to perform the reset:

1. Go to Settings → Applications → Application Management.
2. Click on the three dots in the top right corner → select Reset application settings.
3. Confirm action. Once the reboot is over, all locks will be removed.

Important: This method will also reset permissions for all applications, turn off notifications and return standard call settings, and after the procedure, you will have to reconfigure access to the microphone, camera and geolocation for instant messengers.

If the reset doesn't work, the last option is a hard reset, but before that,

• 📱 Make a backup copy through Settings → Additionally. → Backup and reset.
• 🔐 Make sure you have access to your Mi Account – you will need authorization after the reset.
• 📋 Save it. IMEI phone (click *#06#) in case of network problems.

💡

Resetting locking is not the same as resetting to factory settings: the first method saves your data, the second method deletes everything.

6. Features for different Xiaomi models

The blacklist management interface may vary depending on the model and version of MIUI, and here are the key nuances for popular devices:

On MIUI devices for POCO (e.g., POCO F5), the path to blacklisting may be different.

1. Open Settings and enter the lock in search.
2. The system will show all related sections, including hidden ones.

For models with double SIM-A card (for example, Redmi Note 12 Pro)+) check:

• 📱 Locking on each SIM separately (Settings) SIM-map → Additionally).
• 🔄 Call forwarding settings – sometimes they conflict with the blacklist.

Frequent Mistakes and How to Avoid Them

When working with a blacklist on Xiaomi, users often face typical problems.

• 🔄 "Number removed from list, but no calls pass" → Check the lock in messengers (WhatsApp, Viber) or operator settings (type *111# for MTS/Beeline).
• 📵 "I can't find a blacklist after the update" → Use search in settings or reset the phone app settings (Settings) → Annexes → Phone. → Warehouse → Reset).
• 🔒 "MIUI Ask for a password to change the lock" → This is Mi Account protection. Enter your Xiaomi account password or reset it via account.xiaomi.com.
• 📱 "The lock screen displays a notification of a missed call, but it is not in the log" → That means the number is locked at the system level. → Notifications → Lock log.

If after all the manipulations the number is still blocked, the problem may be:

• 📡 Operator settings (some tariffs include automatic spam blocking).
• 🔧 Custom firmware (e.g., Xiaomi.eu may have its own locking rules).
• 📱 Hardware failure (rarely, but occurs when the communication module is damaged).
