The blacklist on Xiaomi smartphones is a useful feature for blocking annoying calls and messages, but sometimes important contacts get into it by mistake. If you accidentally add a number to the lock or buy a used phone with someone else's settings, unlocking can be a non-trivial task. In this article, we will discuss all the current ways to remove numbers from the blacklist on devices with MIUI 12, 13, 14 and 15, including hidden methods for older models.

Xiaomi has a unique feature of duplicating lock functions in different parts of the system, which can be locked separately for calls, SMS and even for specific messengers (WhatsApp, Telegram), we will show you how to check all possible sources of locking and guaranteed to unlock the number. Instructions are suitable for all lines: Redmi Note 12/13, Poco X5/F5, Xiaomi 13/14 and even outdated models on MIUI 10-11.

1. Standard method: through phone settings

The most obvious method is to use a built-in lock menu, which works on all current versions of MIUI and does not require additional applications. Importantly, some operators (such as MTS or Beeline) can impose their own locks on top of the system locks, they will have to be removed separately.

Instructions:

• 🔍 Click on three dots in the upper right corner → Settings
• 🚫 Select Number Block (or Blacklist in older versions)
• ✏️ Find the number you want in the list and swipe it left or click Delete

If the number does not appear in this list, check the other sections:

• 💬 Communications → Settings → Blocking and spam
• 👤 Contacts → Settings → Blacklist (if the number is saved in the phone book)

⚠️ Note: Some Xiaomi firmware for Redmi 9A/9C POCO M3 The item "Block numbers" can be called "Spam and lock." If you can't find the section, use the search by settings (the magnifying icon in the top menu).

3. Hidden method: through the engineering menu (for experienced)

If the standard methods didn't work, you can try resetting your locking settings through the engineering menu, which is suitable for devices on MIUI 12-14 and requires caution - wrong actions can disrupt the phone. Do not use it unless you are confident in your skills.

⚠️ Note: On devices with Qualcomm Snapdragon processors (most of Xiaomi’s flagships), the engineering menu may not contain a lock section.

4 Unlocking through the "Security" application

Xiaomi’s Security app (or Global Firmware Security) has its own locking module, which sometimes duplicates the system blacklist, which is especially relevant for devices with MIUI 13/14, where the anti-spam function is put into a separate application.

How to check:

• 🛡️ Open the Security app (shield icon)
• 🔍 Go to the section "Number Lock" or "Antispam"
• 📋 Check the tabs: 📞 Locking down calls 💬 Blocking communications 🌐 Network lock (for operator services)
• ✅ Remove unnecessary numbers via swipe or menu

Some firmware (e.g., Xiaomi 12T or Redmi K50) in the Security app have a Lock Log feature, where you can see the history of blocked calls and unlock them retroactively.

💡

If the Security app is not on the menu, check the Google Services folder or install it through the Mi App Store, which can be called Security or Mi Security on global firmware.

5. Resetting phone settings (extreme case)

If all previous methods failed, the radical solution is to reset the phone to factory settings, which will remove all data from the device, including the blacklist, but also delete:

• 📸 Photos and videos (if not saved in Mi Cloud)
• 👥 Contacts (if not synced with Google)
• 🎮 Installed applications and their data
• 🔑 Passwords from Wi-Fi and accounts

How to do the reset correctly:

1. Create a backup through Settings → About Phone → Backup
2. Go to Settings → Additional → Recovery and Reset
3. Select Settings Reset (not to be confused with Network Reset!)
4. Confirm the action and wait for the reboot (it will take 5-10 minutes)

⚠️ Note: On devices with an unlocked bootloader, a reset may cause Mi Account protection to be activated. Make sure to remember the username and password from your Xiaomi account, otherwise the phone will be locked completely.

Factory reset should be the last option, and 90% of the time, you can unlock the number through standard settings or the Security app.
