Why Xiaomi users want to turn off incoming calls
Xiaomi’s MIUI-based smartphones offer flexible call management settings, but sometimes standard features aren’t enough. Users are looking for ways to completely disable incoming calls for reasons ranging from focusing on work to avoiding intrusive call centers. Unlike iPhones, which lock through Concentration Mode, Redmi and POCO require a combination of system tools.
It is important to understand the difference between a temporary shutdown (for example, through Do Not Disturb mode) and a complete lockdown of all incoming contacts: the first option retains the ability to take important calls from selected contacts, the second one radically cuts off all connections. It is also important to note that certain methods (e.g., disabling) SIM-maps) will affect both outgoing calls and mobile Internet.
In this article, we will look at MIUI-unique blocking methods, including hidden developer settings and third-party applications that do not require root rights. All methods are tested on MIUI 12.5-14 firmware and are relevant for models from 2020-2026.
Method 1: Do Not Disturb (DND) with maximum restrictions
The safest and most reversible method is the built-in Do Not Disturb mode, which allows you to flexibly configure exceptions, but with the right settings, blocks all incoming calls, including repeat calls.
How to set up:
- 📱 Open the Settings. → Sound and vibration → Don't disturb.
- 🔄 Select Always in the section "Automation Rules"
- 📞 In the Calls section, set the switch to the position Block everything
- 🔔 Turn off the option of repeat calls (otherwise the second call in 3 minutes will pass)
- 📌 Enable mode through the notification panel or on schedule

This method does not affect SMS and notifications from applications, and complete isolation will require additional disconnection of mobile data or transfer the phone to flight mode.
⚠️ Attention: B MIUI 14 upon activation DND The notification panel automatically turns on the exception for "Favorite Contacts." To avoid this, set the mode exclusively through Settings.
Method 2: Block all contacts through a blacklist
If you want to block all but a select few subscribers, use a built-in blacklist, which is a good way to fight spam, but requires manually adding each number — which is inconvenient with a lot of contacts.
Algorithm of action:
- Go to the phone. → Journal → ⋮ → Settings → Number locking
- Activate the option to Block Unknown Numbers
- Manually blacklist all contacts from the phone book (button +)
- To speed up the process, export contacts to.vcf and import them to the blocker app.
| Advantages | Deficiencies |
|---|---|
| Doesn't require root rights | It is difficult to work with a large number of contacts |
| It retains the possibility of outgoing calls | Does not block service numbers (banks, operators) |
| It works on all versions of MIUI. | Spam numbers can bypass the lock |
💡
Use Truecaller to automatically blacklist spam numbers, it integrates with the MIUI system blocker and updates the database daily.
Method 3: Disconnection SIM-Programming (without physical extraction)
To completely disable incoming and outgoing calls without physical extraction SIM-Use the hidden function of the card MIUI. This method is useful if you need to temporarily “disappear” from the network, retaining access to Wi-Fi and applications.
Instructions:
- Open the Settings. → SIM-maps and mobile networks
- Choose an active one SIM-map, SIM 1)
- Turn off the switch. Turn on. SIM-map
- Confirm the action in the dialog window
After that:
- 📵 Mobile phone calls will disappear (and SMS)
- 📶 Connection to Wi-Fi and mobile data will be saved (if only enabled) 4G/5G)
- 🔄 To return the communication is enough to re-enable SIM customized
⚠️ Note: On some models POCO (for example, POCO X3 Pro after disconnection SIM-The cards are missing and the mobile Internet. Check this in advance if you depend on the Internet. 4G.

Method 4: Using the "In-Air" mode with exceptions
Airplane Mode completely shuts down all wireless modules, but in MIUI it can be configured flexibly, for example, leaving only Wi-Fi on to receive calls via WhatsApp or Telegram, but blocking standard calls.
How to set up:
- 🛩️ Enable "In the plane" mode through the notification panel
- 🔄 Back to Settings → SIM-maps and mobile networks
- 📶 Enable Mobile Data (calls will remain blocked)
- 📊 If necessary, activate Wi-Fi and Bluetooth.
This method is suitable for:
- 🏠 Home Use (Calls via Messengers) + stable Wi-Fi)
- 🎮 Players who don’t want to interrupt online games
- 💼 Coworking (without distracting calls, but with access to corporate chats)

Method 5: Third-party applications for radical blocking
If the built-in MIUI tools don't work, consider specialized applications that offer advanced features, such as:
- 📊 Statistics of blocked calls by number/time
- 🤖 Automatically Adding Spamers to the Blacklist
- 📢 Personalized SMS-Responses to blocked calls
- 🔄 Lockdown schedule (for example, only during working hours)
Top.-3 Proven applications for Xiaomi:
| Annex | Features | Cons |
|---|---|---|
| Call Blocker | Blocking by keywords in the room, call log | Advertising in the free version |
| Should I Answer? | Public database of spam numbers, subscriber ratings | Requires access to contacts |
| Blacklist Plus | Flexible locking rules, backup lists | Paid functions (from 199)₽) |
Before installing, check the application permissions in Settings → Apps → Permissions. To work properly, you will need rights to:
- 📞 Reading the call log
- 📱 Changing telephone settings
- 📎 Access to contacts (optional)
⚠️ Note: Blocking applications may conflict with system services MIUI, firmware-in-chief MIUI 13+. After installation, restart your phone and check the stability of the connection.
What to do if the calls keep coming
If none of the methods worked, the problem may lie in:
- 🔧 Firmware: On custom ROM (For example, LineageOS system blockers are not working properly.
- 📡 Operator: Some operators (e.g. Tele2) miss service calls even in mode DND.
- 🤖 System failures: After the update MIUI lockdown settings are reset.
Actions for diagnosis:
- Check the call log for missed calls with the label Blocked.
- Install an alternative call app (like Google Phone) and lock it.
- Reset network settings: Settings → SIM-map → Resetting mobile network settings.
- Update your firmware to the latest stable version via Settings → About Phone → System Update.
💡
If calls are made despite activated DND, check the settings of the Phone app. In some versions of MIUI, it ignores system limitations and requires a separate lock setting.
