How to add a number to the blacklist on Xiaomi: all ways to block

Boring calls from spammers, collectors or former acquaintances can spoil the mood of even the most patient user. Fortunately, Xiaomi smartphones based on the MIUI shell offer built-in tools to block unwanted contacts without having to install third-party applications. In this article, we will analyze all the current ways of entering numbers into the blacklist, including nuances for different versions of firmware and models (Redmi Note 12, POCO X5, Xiaomi 13T, etc.).

It is important to understand that locking on Xiaomi works in a complex way: it blocks not only incoming calls, but also SMS messages from the blocked number, while the subscriber will not be notified of the blocking - his calls will be automatically reset and messages will disappear without a trace.

Method 1: Blocking through the call log

The fastest method is to blacklist a number directly from the call log, which is convenient when you have just received a call from an unwanted caller and want to stop further attempts.

The instructions are relevant for MIUI 12/13/14 (including global and Chinese firmware versions):

1. Open the Phone app (the tube icon on the home screen).
2. Go to the magazine tab (watch icon in the bottom menu).
3. Find the number you want to block in the list and tap it.
4. In the contact card that opens, click on three vertical points (⋮) top-right.
5. Select Add to the blacklist (or Block in English firmware).
6. Confirm the action in the pop-up window.

Now, all calls and text messages from this number will be automatically ignored. Note that in some regional firmware, the menu item may be called Lock Number or Spam, and the essence remains the same.

Is the number saved in the contacts? (if yes, delete it first)

Is blacklisting enabled with Mi Account?

Have emergency call exception settings been checked?

Method 2: Adding through security settings

If you need to block a number that hasn't called yet (for example, you know a spammer number in advance), use the Security section in your system settings. This method is universal and works even for numbers that aren't saved in the phone book.

Sequence of action:

• 📱 Open Settings (the gear icon on the main screen).
• 🔒 Go to the Appendix section → Security → Blacklist (or Passwords & Security) → Blocklist in the global firmware).
• ➕ Click on the plus badge (+) top-right.
• 📞 Enter the number manually or select it from the log/contacts.
• 💾 Save the changes with the button Ready.

In the same section, you can manage already blocked numbers: delete them, temporarily disable the lock, or add exceptions. For example, if you blocked the number by mistake, you can quickly unlock it without permanently deleting it from the list.

Method 3: Blocking SMS messages

In MIUI, it is set up separately from calls, although integrated into the same blacklist. If you are flooded with SMS ads or fraudulent emails, follow these steps:

• 💬 Open the Messages app (the envelope icon).
• 📄 Find a dialog with an unwanted number and open it.
• ⋮ Slip on three dots in the top right corner.
• 🚫 Choose Block and report spam (or Block & Report spam).
• ✅ Confirm the lock in the pop-up window.

After that, all messages from this number will be automatically deleted, without even getting into the Spam folder. Importantly, if you block the number via SMS, this will not block calls from it - you need to use the first or second method to completely block calls from it.

Features of the blacklist on different models Xiaomi

Despite the general logic of the work, some Xiaomi models have nuances in the implementation of the blacklist, due to differences in the hardware platform and versions of MIUI.

On models with Snapdragon 8 Gen 2 chips (such as Xiaomi 13 Ultra), the blacklist supports geolocation locking – you can block calls from certain countries or regions. This feature is hidden in the engineering menu and requires activation through the code # #4636## (Phone information → More → Call blocking by region).

⚠️ Attention: On devices with dual SIM-cards (for example, Redmi Note 12 Pro)+) The blacklist is separate for each SIM, so if you want to block the number on both cards, add it to the list twice for each card. SIM separately.

How to restore the blacklist after resetting settings

Many users face a problem: once the phone is reset to factory settings or flashed, all locked numbers disappear, and to avoid this, Xiaomi offers two ways to back up the blacklist:

1. Synchronization with Mi Account: 🔄 Enable synchronization in Settings → Mi Account → Synchronization → Blacklist. 📱 Link the device to your Xiaomi account (unless previously done). ☁️ After reset, log in to the same account – the list will be restored automatically.

Manual export:

• 📄 Go to Settings. → Annexes → Security → Blacklist.
• ⤵️ Click on the three dots in the top corner and select Export.
• 💾 Save the blacklist.db file to the cloud or on PC.
• ⤴️ After reset, import the file back through Import.

If you can’t make a backup and the list has been lost, try to restore it through the call log: Xiaomi stores logs of the last 30 days, even after the reset. Use the Mi Mover app (available in Settings → Additional).

💡

Before selling or transferring your phone to another person, make sure to clear the blacklist through Settings → Reset → Clear the blacklist. Otherwise, the new owner will be able to see the numbers you have blocked!

What to do if the lock is not working

Sometimes users are faced with a situation where the blocked number is still called or sends a text message.

• 🔄 Update the firmware: In older versions MIUI (below 12.5) were blocked bugs. Check the updates in Settings → The phone. → Updating the system.
• 📵 Check for exceptions: Some system applications (e.g. Security) may have permission to bypass the blacklist. → Annexes → Permits → Special access → Bypass the lock and disable unnecessary exceptions.
• 📡 Network Reset: If the problem is only with SMS, reset your mobile network settings in Settings → SIM-maps and mobile networks → Resetting settings.
• 🛠️ Database failure: Remove the Phone app cache and Messages in Settings → Annexes → Application management.

⚠️ Note: If you use third-party applications to block calls (such as Truecaller or CallApp), they may conflict with the built-in blacklist. MIUI. Disable duplicate functions in the settings of these applications.

Alternative methods of blocking

If standard MIUI tools don’t suit you, consider alternatives:

• 🤖 Google Messages: Google’s app supports blocking SMS and sync calls via Google account. Install it from Play Market and activate Spam protection feature.
• 📱 Telecom operator: Most mobile operators (MTS, Beeline, Television)2) offer a blacklist service at the level of SIM-It's activated through the map. USSD-command, for example, *111*777# for MTS).
• 🔒 Firewall applications: Utility like NetGuard or AFWall+ They can block access to the network of specific numbers, which is useful against the SMS-spam.

The advantage of operator lock is that it works even with or without the phone turned off. SIM-However, such services are often paid (from 30 to 100 rubles per month) and have a limit on the number of numbers (usually 10-20).

💡

The built-in MIUI blacklist is the most reliable way, as it works at the system level and does not depend on third-party services, but for maximum protection, it is recommended to combine it with operator lock.
