How to block a contact on Xiaomi: all ways in 2026

You can block unwanted contact on a Xiaomi smartphone in seconds if you know where to look for the right settings. Depending on the version of MIUI and the phone model (Redmi Note 12, POCO X5, Xiaomi 14, etc.), the interface may be slightly different, but the overall algorithm remains the same. In this article, we will analyze all the current methods, from standard system tools to locking in messengers and through third-party applications.

It is important to understand that blocking a contact at the MIUI level automatically stops not only calls, but also SMS, and in some cases notifications from system applications (for example, Messages or Phone). If you need to block a user only on WhatsApp or Telegram, you will need a separate setup in the messenger itself.

Before you start, check the MIUI version on your device: go to Settings → About Phone → MIUI version. The instructions below are relevant for MIUI 14 and later (including HyperOS), but most features can be used on older versions (for example, MIUI 12.5).

1. Blocking contact through the standard application “Phone”

The fastest way is to use the built-in Phone app, which works on all Xiaomi smartphones, regardless of model, and does not require the installation of additional programs.

Open the Phone app (the handset icon on the home screen). Go to the Contact tab and find the number you want in the list. tap the contact to open the card, then click on three dots (⋮) In the upper right corner, you can select Lock. The system will tell you to confirm the action, agree. Okay, now that caller will not be able to call you or send you a message. SMS.

• 📱 Suitable for: All models Xiaomi/Redmi/POCO on MIUI or hyperos.
• 🔄 You can unblock the contact in the same menu.
• 📵 The effect is to block calls and SMS, but it doesn't affect messengers.

If the contact is not saved in the phone book but has called you before, look for it in the Call Log (Recent tab in the Phone app).

💡

To quickly find a contact to lock, use the search bar at the top of the Phone or Contacts app.

2.Manage blocked contacts in MIUI settings

All locked numbers are stored in the central menu of MIUI settings, where you can not only add new contacts to the blacklist, but also edit existing records, as well as configure lock rules (for example, for unknown numbers).

Go to Settings → Applications → Phone → Number Lock. In this section, you will see three tabs:

• 📞 Blocking calls – all blocked numbers are displayed here.
• 💬 Blocking messages – a list of numbers from which it is forbidden to receive SMS.
• ⚙️ Settings – additional settings (for example, blocking hidden numbers).

To add a new number manually, click Add (+) and enter the data, and you can import the numbers from the file or export the current blacklist for backup.

3. Blocking in messengers: WhatsApp, Telegram, Viber

If a contact bothers you with messengers, standard blocking at the MIUI level will not be enough. Each messenger has its own blacklist mechanism, and blocking in one application does not apply to others.

Here’s how to do this in popular services:

• 📲 WhatsApp: Open a chat with a contact → three-point (⋮) → More. → Lock down.
• 💬 Telegram: Go to the user profile → press ⋮ → Block (or swipe left in the chat list and select Block).
• 📱 Viber: Open the chat room → Information → Lock down.
• 💭 Facebook Messenger: Tap the contact name → Lock down.

Important: blocking in instant messengers does not affect calls and SMS through standard Xiaomi apps. To completely isolate contact, use both methods.

In Telegram and WhatsApp, a blocked user will not be able to see your online status, the time of your last visit or a change in your profile. In Viber, a lock also hides your status "on the network", but the user can continue to send you messages (they just won't reach).

4.Use of third-party applications to block

If the built-in MIUI tools aren’t enough (for example, you need to block keywords in SMS or lock schedule), you can use third-party applications.

• 🛡️ Truecaller – blocks spam calls and identifies unknown numbers.
• 📵 Blacklist Plus – allows you to create lock rules by time of day or day of the week.
• 🔍 Call Blocker – supports locking by geolocation or prefix of the number.
• 📊 SMS Blocker - filtering SMS by keywords (e.g., "credit", "promotion").

Before installing, check the permissions of the application: it must request access to the Call Log, SMS and Contacts. Some programs (for example, Truecaller) require registration and sync with the cloud, which may not be desirable from a privacy perspective.

⚠️ Warning: Third-party blocking apps may conflict with built-in features MIUI. If the standard calls have stopped working after the installation, or SMS, disable the third-party blocker or add it to the exceptions in the battery settings (Settings) → Battery → Optimizing the battery).

To install apps, go to Google Play Market and type the name in the search bar. After installing, follow the instructions of the customizator - usually just provide the necessary permissions and add numbers to the blacklist.

5. Blocking of unknown and hidden numbers

If you get calls from hidden numbers (displayed as Unknown or Private Number), MIUI has a separate setting to filter them, activating it, you automatically reset all incoming calls without an ID.

To enable the blocking of hidden numbers:

1. Go to Settings → Applications → Phone → Lock numbers.
2. Select the Settings tab (cog in the upper right corner).
3. Activate the switch to Lock hidden numbers.
4. If you wish, add exceptions (e.g. bank or delivery numbers).

This feature is useful for spammer control, but beware: some legitimate services (such as bank call centers or courier services) can call from hidden numbers.

💡

Blocking hidden numbers is an effective way to fight spam, but can miss important calls from support or delivery services.Always check the missed call log.

6. How to Unblock Contact on Xiaomi

If you change your mind or accidentally block the number you want, unlocking it is as easy as blacklisting it, and you can do this in two ways:

Method 1: Through lock settings

1. Open Settings → Applications → Phone → Lock numbers.
2. Go to the Call Block tab or Message Block (depending on what you want to unlock).
3. Find the number in the list and swipe left or tap on the basket icon (🗑️).
4. Confirm the action.

Method 2: Through the contact card

1. Open the Contacts app and find the blocked number.
2. Tap the contact, then press. ⋮ → Unlock.

Once unlocked, the contact will be able to call you again and send you SMS. If the unlocked number has previously sent you messages, they may arrive with a delay (depending on the carrier).

7. Frequent problems and their solutions

Sometimes, the blocking of contacts on Xiaomi works incorrectly. Let’s look at typical situations and ways to fix them.

⚠️ Note: If the number keeps calling you after blocking, check if the phone has a third-party call app (e.g. Google Phone or Truecaller) in which case the lock needs to be configured in both apps.

If none of the methods worked, try resetting the phone app settings:

1. Go to Settings → Applications → Application Management.
2. Find the phone in the list and tap it.
3. Select Warehouse. → Clear the data.
4. Reboot the phone.

This procedure will reset all lock settings, so after the reboot you will have to add numbers to the blacklist again.
