How to completely disable incoming calls to Xiaomi: all working methods

Xiaomi, Redmi and POCO smartphone owners often face the need to temporarily or permanently block incoming calls, ranging from preparing for an important event to avoid intrusive calls from operators or collectors. Unlike Do Not Disturb mode, which simply mutes notifications, shutting down calls completely requires deeper settings.

In this article, we’ll look at all the current ways, from standard MIUI features to hidden engineering menu features. It’s important to understand that some methods may differ depending on the firmware version (e.g. MIUI 12 vs MIUI 14) and device model. We’ve taken these nuances into account and prepared universal instructions that work even on low-end models like the Redmi 9A or the flagships of the Xiaomi 13 series.

If you need to disable calls selectively (for example, only from unknown numbers) or completely (including emergency calls), you will find a solution below, and we will also discuss how to circumvent operator restrictions and what to do if mobile Internet is lost after a disconnection.

1. Standard method: Do not disturb mode with call blocking

The most obvious, but often underrated, method is the use of built-in Do Not Disturb (DND) mode, which in recent versions of MIUI allows you not only to mute notifications, but also completely block incoming calls, including repeat calls.

1. Open Settings → Sound and vibration → Do not disturb.
2. Activate the slider at the top of the screen.
3. Click Calls and select No One (this will block all incoming calls).
4. In the Repeat Calls section, set Reject to avoid breaking through the lock.

⚠️ Note: In some firmware (for example, MIUI 11 for Redmi Note 8 Pro) No one may be absent, in which case use a workaround: select Only contacts and pre-delete all contacts from the phone book (or transfer them to the Blacklist»).

💡

If you only need to turn off calls for a certain time (e.g. overnight), set the schedule in the same Do Not Disturb menu. Set the interval and select Repeat daily.

This method does not affect SMS or mobile Internet, but has a limitation: emergency numbers (e.g. 112) will still pass, and you will need one of the following methods to block them.

2. Blocking through the "Black List" (for sample numbers)

If you only need to disable calls from specific subscribers (such as spammers or collectors), use a built-in blacklist, which works on all Xiaomi models, including the POCO X3 Pro and Redmi 10, but requires manual addition of each number.

• 📱 Open the phone application (pipe icon).
• 🔍 Go to the Journal section and find the desired number.
• 📛 Press the number. → ⋮ (three-point) → Add to the blacklist.
• 🔄 For mass addition: Settings → Annexes → Phone. → Blacklist. → Add.

🔹 Nuance: The blacklist numbers won’t be able to call you, but they will be able to send you a call. SMS. To block messages, install a third-party app like Truecaller or Call Blocker (available on Google Play).

If you need to block all incoming calls, including unknown ones, proceed to the following method.

3. Engineering menu: complete disabling of incoming calls

For power users willing to work with hidden settings, there is a way to turn off incoming calls at the modem firmware level, which works even if standard methods do not help (for example, on limited firmware).

📌 Instructions:

1. Open the phone app and enter the code: ##4636##
2. In the menu that opens, select Phone Information (or Phone Information).
3. Scroll down to the Incoming Call section.
4. Click Reject All Incoming (Reject All Incoming)
5. Save the settings and restart the device.

⚠️ Note: After using this method, you will not be able to receive any calls, including emergency (112, 911, etc.) To return everything back, repeat the steps and select Accept All Incoming).

🔧 Technical details: On some models (e.g, POCO F4 GT) The engineering menu can be blocked by the manufacturer, in which case use an alternative code:

##86583##

or install the MTK Engineering Mode application (for devices running MediaTek processors).

4. Disabling calls via SIM-card (operator services)

If you need to temporarily block incoming calls at the operator level (for example, when traveling abroad), you can use the services of a mobile provider. This method is independent of the phone model and works even on Xiaomi with custom firmware.

📢 Important: Call blocking service does not disable the operator SMS Some operators (e.g. MegaFon) may also charge for this feature.

✅ Plus method: Calls are blocked before they hit your phone, which saves battery power (no unnecessary notifications).

❌ Cons: Does not work for Internet calls (WhatsApp, Viber, etc.).

5. Third-party applications: extended lock

If you don't like MIUI, you can install specialized applications that offer flexible settings: blocking by keyword, schedule, geolocation, and even voice.

• 🛡️ Truecaller – blocks spam calls and SMS, There's a database of fraudsters.
• 📵 Call Blocker – Allows you to create whitelists with flexible rules.
• 🔇 Should I Answer? – Analyzes real-time numbers and alerts you to suspicious calls.

On Xiaomi models with a Snapdragon processor (such as the Xiaomi 11T Pro), some blockers may conflict with system services. If call notifications disappear after installation, try disabling battery optimization for the application in the AutoRun settings.

6. Radical method: shutdown SIM-map

If you need to completely disable mobile communications (including calls and the Internet), you can deactivate the phone. SIM-This is a way to do things with two SIMs, where you only have to leave one working.

⚠️ Note: Some operators (e.g. Tele2) have a redirect service that is paid for. Check the rates by 611 (for Tele2) or on the operator's website.
