How to blacklist a number on Xiaomi: all ways 2026

Unsolicited calls from spammers, collectors or ex-friends can be a serious mess. Fortunately, Xiaomi’s MIUI-based smartphones offer several built-in tools to block such contacts, from a basic blacklist to advanced SMS filters. In this article, we will discuss all the current ways to blacklist numbers on Redmi, POCO and Mi devices (including models from 2023-2026), as well as how to manage blocked contacts and avoid typical errors.

If you use MIUI 14/15, the algorithm may be slightly different from the older versions — we've taken these nuances into account. And for those who don't have the standard features, here's an overview of trusted third-party applications with advanced capabilities.

Method 1: Blocking through the call log

This is the fastest way to blacklist a number if you've already been called by a caller, and MIUI allows you to do it in two taps, without having to search for a number in the contacts.

Open the Phone app and go to the Log tab. Find an unwanted number in the list and tap it. In the window that opens with the details of the call, click on three vertical dots (⋮) in the upper right corner and select Add to the blacklist. Confirm the action in the pop-up window.

• 📱 It works on all models: from Redmi Note 12 to Xiaomi 14 Pro.
• 🔄 The number is blocked immediately for calls and SMS.
• ⚡ If the contact is saved in the phone book, it will be deleted automatically.

Note that in MIUI 15, the number disappears from the call log after blocking, and to see it again, you will have to temporarily disable the blacklist (we will discuss this below).

💡

If the number is hidden (defined as "Unknown" or "Private"), you can't block it through the log. №3 or third-party applications.

Method 2: Addition via contacts

If an unwanted number is stored in your phone book (or you want to block an existing contact), do so through the Contacts app. Open the caller card, tap three dots (⋮) and select Add to the blacklist.

Unlike the previous method, it has the option of selective blocking: you can only disable calls or only SMS. To do this, after clicking Add to the blacklist, select the desired option from the menu that appears, which is convenient if, for example, you want to receive messages from the contact, but do not want to receive calls from him.

An important nuance: in MIUI 15, a blocked contact is not removed from the phone book, but simply marked as blocked.

Method 3: Manually enter the number in the blacklist

If you need to block a number that hasn't been called or saved in contacts, use manual input. → Annexes → Phone. → Blacklist (or Settings) → SIM-maps and mobile networks → Blacklist on some models).

In the window that opens, click on the + icon in the upper right corner and enter the number manually. Here you can specify the type of lock: calls, SMS or both, which is suitable for blocking hidden numbers (if you know their real format) or for preventive blocking of spam centers.

• 🔢 Numbers in formats are supported: +79XXXXXXXXX, 89XXXXXXXXX, 9XXXXXXXXX.
• 📵 You can add up to 500 numbers to the blacklist (limit) MIUI).
• 🔄 To delete the number, swipe it to the left and press Delete.

Method 4: Blocking through Messages (SMS)

Spam mailings and unwanted SMS You can block it directly from the Message app. Open the dialog with the right number, tap it on three dots (⋮) in the upper right corner and select Add to the blacklist. MIUI 15 This item may be called Block and Delete.

The main feature of this method is that the blockage applies only to the SMS. If you want to ban calls and have to add a number through the phone settings (method). №3) But there is a convenient feature to delete all messages from this subscriber - it clears the chat automatically.

⚠️ Note: In some regions (e.g. Russia), mobile operators may ignore the blocking. SMS In this case, the spam will continue to arrive but will not appear in the Messages app. To completely stop sending, contact the operator and request a lock on his side.

If you receive spam from short numbers (like 1234 or 5555), you can also block them through this menu, but these numbers are often used by banks and services - make sure you don't block important notifications.

Method 5: Third-party applications for extended locking

The built-in MIUI tools are good for basic locking, but if you need additional features — like keyword filtering in SMS or blocking entire regions — you’ll have to install a third-party app.

• 🛡️ Truecaller – identifies spammers from a database, blocks hidden numbers, maintains blacklists by category (e.g., “Collectors” or “Crackers").
• 📵 Blacklist Plus – allows you to create mask lock rules (for example, all numbers with a code) +375), keeps a log of blocked calls.
• 🔍 Should I Answer? – Analyzes real-time numbers and warns of potentially dangerous calls.

Before installing, check the app's permissions: it should request access to Call Log, SMS, and Contacts. Some apps (like Truecaller) require registration and may collect data about your contacts - keep this in mind if you value privacy.

⚠️ Attention: On devices with MIUI 14/15 Some blocking applications may conflict with built-in features. If standard blacklists stop working after installation, disable duplicate functions in Settings → Annexes → Permits → Auto-start.

For maximum protection, we recommend combining built-in MIUI tools with third-party applications, for example, you can use Truecaller to identify spammers, and block through a standard blacklist.

To unlock the number:

2. Click Remove from the blacklist (or Unblock in MIUI 15).
3. Confirm the action.

If you want to temporarily disable the lock (for example, to check if an important contact called you), move the Blacklist slider to the Off position.

💡

In MIUI 15, locked numbers are not displayed in the call log, even if the lock is disabled, and to see them, you need to completely remove the number from the blacklist.

On some models (e.g. POCO F5 or Redmi K60), the path to the blacklist may be different. If you don't find the menu on the standard path, search in the settings - type in the blacklist request.

Typical problems and their solutions

Sometimes users find that the lock is not working or the number keeps calling, and here are the most common reasons and ways to fix them:

If all the blocked numbers were lost after the MIUI update, it could be due to a reset, and you can only restore the list manually - unfortunately, Xiaomi does not sync the blacklists with the Mi Account account.
