How to completely or selectively disable calls to Xiaomi: all ways

Xiaomi smartphone owners often face the need to temporarily or permanently turn off incoming calls — whether due to an important meeting, a night’s sleep or annoying spammers. Unlike iPhones or devices on pure Android, MIUI offers several ways to manage calls, including hidden features. However, not all users know that in addition to the standard “Do not disturb” mode, there are more flexible settings, from blocking individual contacts to completely disabling mobile communication through the engineering menu.

In this article, we will discuss 5 proven methods to disable calls to Xiaomi (including Redmi, POCO and Black Shark models), taking into account the features of different versions of MIUI 12-14. You will learn how to configure exceptions for important contacts, bypass operator restrictions and even temporarily “mask” a number as a non-existent. All instructions were tested on current firmware in 2026 and do not require root rights.

1. Standard Do Not Disturb (DND) mode

The most obvious, but often underrated, way to do this is to use the built-in Do Not Disturb (DND) mode, which works differently in MIUI than it does on Android, where you can flexibly configure exceptions to time, contacts, and even notification types, such as allowing calls from Favorites only, or blocking all notifications except the alarm clock completely.

To activate the mode:

• 📱 Open the Settings. → Sound and vibration → Don't disturb.
• ⏰ Select the schedule: Always, on schedule (for example, from 23:00 to 8:00) or Before the shutdown.
• 🔕 In the Exceptions section, set up: 📞 Calls. → From all/Contacts only/Selected only. ⚠️ Repeated calls (if one number calls 2 times within 3 minutes, the signal will sound).
• 🔄 Don’t forget to switch on the switch at the top of the screen!

💡

If DND does not work on calls, check the phone app settings: sometimes MIUI updates reset the permissions for system notifications.

⚠️ Attention: B MIUI 14, a bug has appeared that makes Do Not Disturb mode ignore exceptions for repeat calls. If it is critical that you do not miss an urgent call, use alternative methods from the following sections.

2. Blocking individual numbers through the “Black List”

If you only need to disable calls from specific subscribers (such as spammers or annoying colleagues), MIUI has a built-in blacklist. Unlike many other firmware, it works at the system level, meaning that a locked number will not be able to reach even if you reboot your phone or reset your network settings.

Instructions for adding a number to the blacklist:

1. Open the phone application (pipe icon).
2. Go to the magazine tab and find the desired number.
3. Tap the number. → ⋮ (three-point) → Lock down.
4. Select the option: Block only calls or Block calls and messages.

Make sure the number is added to Settings → Applications → Phone → Lock numbers | The number is displayed in the list of blocked | Try calling from another phone – the answering machine should work | Check if there are no SMS from this number (if you choose a full lock)

-->

🔍 How do I know if a number is locked? MIUI No blocking notifications, but you can check the log of blocked calls:

1. Open the phone. → ⋮ → Settings → Number locking.
2. Slip on the blocked number → Journal.

⚠️ Note: Blacklisting does not work for hidden numbers (where the number is displayed as “Unknown” or “Private”). These will require the use of specialized applications (see section 4).

3. Complete shutdown of mobile communication (In-plane mode + tricks)

If you want to completely disable all incoming and outgoing calls, including emergency numbers (112, 911, etc.), you can use In-plane mode.

• ✈️ The standard on-airplane mode shuts down all mobile communications, but leaves Wi-Fi and Bluetooth active (if they were previously enabled).
• 📵 On some Xiaomi models (e.g. Redmi Note 12 Pro)+) In the “Airplane” mode, Wi-Fi calls still work (if the Calls over Wi-Fi function is activated).
• 🔄 After the mode is turned off, the communication is not restored instantly - it may take 10–30 seconds to re-register in the network.

How to turn off calls through the “On the plane” mode:

1. Swipe down from the top edge of the screen to open the notification bar.
2. Slap the icon. ✈️ Plane mode (or hold it for quick settings).
3. Make sure that Wi-Fi and Bluetooth are turned off (if you need a full “blackout”).

4. Specialized applications for blocking calls

If the built-in MIUI tools don’t suit you (for example, hidden numbers are not blocked or you need advanced statistics), you can use third-party applications.

• 🛡️ Truecaller blocks spam calls and identifies unknown numbers, and the premium version has a Private Mode feature that hides your number from the recipient.
• 🚫 Call Blocker – allows you to create lock rules on masks of numbers (for example, all numbers with a code) +375).
• 🔇 Should I Answer? – analyzes real-time numbers and blocks suspicious calls to the first horn.
• 📊 Hiya – specializes in fraudulent numbers and offers detailed statistics of locks.

⚠️ Note: Call blocking applications require permission to access the call log and SMS. V MIUI 13+ These permissions can be reset after system updates:

1. After installing the application, go to Settings → Applications → Permissions Management → Call Log.
2. Find your app to lock and enable all permissions.
3. Activate AutoRun for the application (in Settings → Battery and Performance → AutoRun Management).

💡 Tip: If you often receive calls from hidden numbers, Truecaller has a feature called “Block all hidden numbers.” However, it does not work 100% – some operators (for example, MTS or Beeline) can bypass this lock.

5. Hidden functions MIUI: engineering menu and USSD-team

For power users who want to get maximum control over calls, MIUI has hidden tools, one of which is an engineering menu that allows you to turn off voice services at the modem level. Careful: incorrect settings can lead to network loss!

How to open the engineering menu and turn off calls:

1. Open the phone app and enter the combination: ##4636##
2. Select Phone Information (or Phone Information).
3. Scroll down to the Set radio band or Preferred network type section.
4. Select GSM only (if you want to leave SMS) or No Service (total disconnection).
5. Click Turn off radio (this will turn off mobile communication before rebooting).

🔧 USSD-call-management:

• 📞 To temporarily block all incoming calls (AntiAon service from MegaFon): *135# (cancel: *135*0#)
• 🔕 To disable all outgoing calls (except emergency calls) from Beeline: *110*331# (cancel: *110*330#)
• 🔄 To check the status of the lock at MTS: *111*085#

💡

USSD-commands are only for your operator and may vary depending on the region.

⚠️ Note: Engineering menu and USSD-commands can reset the network settings or cause temporary loss of communication. Do not use them if you are not sure of your actions. To return to the standard settings, restart your phone or enter:

##4636## → Turn on radio

Alternative methods: second slot SIM, eSIM and virtual numbers

If you need to completely “disappear” from the network for a while, but still stay connected over the Internet, consider these options:

• 📱 Use of the second slot SIM: Put the second phone in. SIM-card with a tariff without outgoing connection (for example, "Internet card" from Tele2). SIM Remove or disable in the settings.
• 🌐 eSIM with limited features: Some operators (e.g. Yota) offer eSIMs only for data transfer. SIM will be impossible.
• 🔄 Virtual Number: Services like Google Voice or Dingtone allow you to create a temporary number for calls over Wi-Fi, and the main number to turn off.
• 📴 Hardware Shutdown: Some Xiaomi models (such as the Mi 11 Ultra) can physically disable the call antenna via disassembling the phone (requires repair skills).

💡 How to fool a number identifier? If you want your number to show as "unavailable" or "hidden" from the recipient, use the prefix before dialing:

• For MTS/Beeline/MegaFon/Tele2: #31# + number (example: #31#79123456789)
• To cancel the hiding of a single call number: *31# + number

⚠️ Note: Some banks and government services block calls from hidden numbers, and the operator may also charge an additional fee for this service (check in your personal account).
