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

Pesky spammer calls, annoying messages from former colleagues, or promotional mailings – Xiaomi smartphones offer several ways to get rid of unwanted contacts. Blacklisting on MIUI devices takes less than a minute, but not everyone knows about all available methods. In this article, we will discuss not only standard system functions, but also hidden features, and consider how to circumvent the limitations of operators and messengers.

It’s important to understand that locking works differently depending on the method: some methods only intercept calls, others also SMS, and still others are able to filter notifications in instant messengers. We tested all options on current models Xiaomi 14, Redmi Note 13 Pro+ and POCO F6 with the latest version of MIUI 15 (HyperOS). If your device is older, check for updates – in old firmware some features may be missing.

Method 1: Blocking through the standard “Phone” application

The most obvious and quickest method is to use the built-in Phone app, which works on all Xiaomi smartphones regardless of the model and firmware version. SMS-message from the selected number.

Instructions:

• 📱 Open the Phone app (the tube icon on the home screen)
• 📝 Go to the Journal section and find the desired number.
• ℹ️ Click on the number, then select Details (or just tap on the contact)
• 🚫 In the upper right corner, press three dots. → Add to the blacklist

Once blocked, the number will disappear from the main call log, but it will be found in the Blacklist section (available through the same three points in the app menu). Please note: this method does not block messages in messengers like WhatsApp or Telegram - they need separate settings.

Method 2: Manage blacklisting through MIUI settings

If you want to block a number that isn't in the call log, or you want to manage the entire list of blocked contacts centrally, use system settings. This method gives you more control: you can add numbers manually, delete them in bundles, and configure exceptions.

How to open the blacklist through settings:

1. Go to Settings → Applications → Application Management
2. In the search bar, enter the “black list” and select the appropriate item
3. Click Add to Blacklist and enter the number manually or select from contacts

Additional options are also available in this section:

• 🔄 Import/Export List – Useful When Changing Phone
• 📊 Lock Log – shows all attempts to communicate from blocked numbers
• 🔔 Block notifications – you can turn off so you don’t see notifications about missed calls

Method 3: Blocking through the Messages app

If the main problem is spam in SMS, not calls, you can block numbers directly from the Message app, which is convenient because it allows you to filter not only individual numbers, but also entire ranges (for example, all numbers from a certain prefix).

Step-by-step:

1. Open the Messages app and find a dialog with unwanted contact
2. Slip on the avatar or sender name at the top of the screen
3. Select Details → Block (or Add to the Blacklist)
4. Confirm the action – now messages from this number will be automatically deleted

Professional advice: In the Messages app settings (three dots → Settings → Spam Protection), you can enable automatic spam filtering from Xiaomi’s database.This feature analyzes the contents of SMS and blocks suspicious messages before they are delivered. However, sometimes it mistakenly filters legitimate messages (for example, from banks), so check the Spam folder once a week.

Method 4: Blocking in messengers (WhatsApp, Telegram, Viber)

Xiaomi’s system blacklist does not affect the work of instant messengers – they need separate settings.

Important: locking in messengers does not sync with the system blacklist of Xiaomi. If you block a contact on WhatsApp, it will still be able to call you via a regular phone call.

Also note that in some messengers (for example, Telegram), a blocked user can:

• 👀 See your messages in shared chats (groups)
• 📎 Send you messages through intermediary bots
• 🔄 Create new accounts to bypass the lock

Method 5: Third-party applications for extended locking

If built-in MIUI features aren’t enough (like blocking numbers by keywords or creating lock schedules), look for third-party apps. We tested some popular solutions and picked the best ones:

Top.-3 Applications to block calls to Xiaomi:

1. Truecaller detects spammers from billions of numbers, blocks SMS and calls, supports Russian.
2. Call Blocker is a simple blocker with the ability to create whitelists and block on a schedule. It works without the Internet.
3. Hiya – specializes in blocking fraudulent calls, integrates with the system phone application.

Warning: Before installing third-party blockers, check their permissions. Some applications request access to:

• 📞 Call log (may be dangerous for privacy)
• 📝 Messages (risk of leakage) SMS confirmation-coded)
• 📍 Geolocation (optional for blocking calls)

💡

Before installing a third-party blocker, back up your contacts via Settings → Google → Backup. This will protect your data in the event of an application failure.

Frequent problems and their solutions

Even after being added to the blacklist, some numbers keep calling, and let's look at the typical situations and ways to deal with them:

Problem 1: Calls pass despite blocking

• 📡 VoIP calls – calls via WhatsApp, Viber and other messengers are not blocked by system means. Solution: block contact in each messenger separately.

Problem 2: SMS is still coming.

If you have blocked the number through the Phone app, but SMS still arrives:

1. Check if the transfer is included SMS to another number (settings) → SIM-map → Message forwarding)
2. Make sure the number is added to the blacklist and in the Messages app
3. Update the firmware – in older versions of MIUI there was an error with filtering SMS

💡

If the blocked number continues to bother you through different channels (calls, SMS, messengers), use a comprehensive approach: block it wherever possible, and consider changing the main phone number.

Problem 3: I can't find a blacklist after the update

After major MIUI updates (e.g., when you switch to HyperOS), the settings may change if you can't find the blacklist:

• 🔍 Use the search in the settings (the magnifying glass icon in the upper right corner)
• 📱 Check the Security section → Lockdown and protection
