How to make no one call, and the Internet works on Xiaomi: all the ways

Smartphones Xiaomi, Redmi and POCO They allow you to flexibly configure the connection, but it's not always obvious how to turn off calls while still maintaining Internet access. You need to focus on your work, avoid annoying salespeople, or just relax without interruptions, but still stay connected on messengers or use mobile traffic. → SIM-maps and mobile networks → Mobile Internet is also disrupting the Internet connection.

Many users mistakenly believe that it is enough to activate In-Air mode, but this blocks both Wi-Fi and mobile data. SIM-The map is physically missing, but then the Internet goes missing. MIUI There are at least 5 working ways to achieve the desired result, and we will discuss each of them in detail, including hidden settings and workarounds for older models.

It is important to note that some methods may depend on the version. MIUI (for example, MIUI 14 and newer, the Do Not Disturb menu interface has changed) and the carrier (some block data transmission when voice services are disabled). SIM-The algorithm will be different – we will talk about this separately.

If you need to completely cut off all incoming calls, including system missed notifications, but leave 4G/5G for the internet, read on.We tested all methods on current firmware (data as of June 2026) and pointed out possible pitfalls.

1.Do Not Disturb Mode with Exceptions

The most obvious and safe way to do this is to use the built-in Do Not Disturb (DND) feature, which blocks all notifications, including calls, but when set up properly, it doesn't affect the mobile Internet.

Go to Settings → Sound and Vibration → Don’t disturb. Activate the slider at the top of the screen. Then click Schedule and select Always (or set a time slot if you only need to turn off calls for a few hours).

Now, the critical step is to go back to the main Do Not Disturb menu and tap "Exceptions." Here, uncheck all the checkmarks in the Calls section (including "Repeat Calls"), but keep the alarm and media options active if you need them, so that all incoming calls will be blocked and the Internet will continue to work.

• ✅ Pros: does not require superuser rights, works on all Xiaomi models, does not affect the speed of the Internet.
• ⚠️ Cons: If someone calls you twice within 3 minutes, the call may pass (depending on version) MIUI).
• 🔄 Alternative: Some firmware has an option called “Alarms Only” that blocks everything except alarm clock signals.

⚠️ Attention: On devices with MIUI 13 and older, there may be no separate call switch in the Exceptions menu, in which case select No Notifications in the Notification Type section, but then messages from messengers will also be blocked.

If you need to leave the option of calls from specific contacts (for example, from family), add them to "Favorites" and allow calls from favorites in the DND settings. To do this, activate the "Contacts" option in the "Exceptions" menu and select "Favorites Only".

2. Disable voice services through settings SIM-map

A lesser known but effective method is to disable voice services for the purpose of SIM-This method works on most Xiaomi devices, but can be blocked by some operators (for example, MTS or Beeline sometimes reset settings after restarting).

Instructions:

1. Open the Settings. → SIM-maps and mobile networks.
2. Choose yours. SIM-card (if two of them).
3. Slip "Voice Calls" and select "Disable" (or "Data Only" if you have one).
4. Go back and make sure that the mobile internet is enabled for this SIM.

After that, incoming calls will be reset immediately (the subscriber will hear the message “Subscriber temporarily unavailable”), and the Internet will continue to work, which is especially useful if you need to permanently turn off calls without the risk of missing an important notification.

Make sure that the mobile internet is turned on for this SIM

Check balance (some operators block data with zero score)

Remember. PIN-code SIM reboot

Save important contacts to the cloud (if you plan to retrieve them) SIM)-->

⚠️ Note: On some tariffs (e.g., Tele2’s All-For 300) the shutdown of voice services may result in an automatic switch to a different tariff plan.

If the menu does not have the option “Data Only”, try an alternative way:

Settings → Memory → Additional → SIM- Card → [Select SIM] → Network Type → Only LTE (without 2G/3G)

This will force the smartphone to use only 4G, where voice calls are transmitted via VoLTE, and if VoLTE is disabled from the operator, calls will not reach, and the Internet will remain.

3. In-plane mode with manual Wi-Fi/mobile data

The classic workaround is to activate In-Air mode and then manually turn on Wi-Fi or mobile data, which is suitable if you don’t need mobile Internet, but only Wi-Fi (for example, at home or in the office).

How it works:

1. Activate In-Air mode through the notification curtain or in Settings → Connections and Sharing → In-Air mode.
2. Once activated, open the notification curtain again.
3. Hold your finger on the Wi-Fi icon (or Mobile Data) to go to settings.
4. Turn on Wi-Fi or mobile internet manually.

Calls are now blocked (since In-Air mode shuts down cellular service), but the Internet is over Wi-Fi or mobile data, a method that is convenient for temporarily shutting down calls, but not suitable if you need to stay in touch constantly over a mobile network.

Note that in In-Air mode, some messengers (such as WhatsApp or Viber) may not show notifications about calls, but messages will come. If you need to completely disable voice calls in instant messengers, use additional settings in the applications themselves.

💡

If the mobile data icon is inactive after the In-Air mode is turned on, try restarting your smartphone, sometimes resetting the restrictions on manually turning on the network.

4.Use of third-party applications to block calls

If built-in methods don’t work (for example, the operator blocks voice services), third-party apps can be used, offering more flexible settings, including blocking by blacklist, schedule or keywords.

Top.-3 Proven applications for Xiaomi:

• 📵 Call Blocker – blocks calls to numbers, keywords (such as “bank”, “credit”) or unknown subscribers. There is a “quiet mode” feature when a call is reset without notice.
• 🔇 Truecaller, in addition to blocking spam, allows you to completely disable incoming calls for all contacts except for the favorite ones.
• 🛡️ Should I Answer? -- analyzes incoming numbers and blocks suspicious ones. You can set up automatic shutdown of all calls at certain times.

To install these applications:

1. Download APK from the official website (for example, Truecaller) or from Google Play.
2. Before installation, allow installation from unknown sources in Settings → Applications → Special Permissions → Installation of unknown applications.
3. Launch the app and set up lock rules (e.g., “Block all incoming calls”).
4. In the application settings, make sure that it does not block mobile internet (some blockers may restrict background data transfer).

⚠️ Note: Apps like Truecaller require access to contacts and call logs. If you're concerned about privacy, use Call Blocker, which works locally, without sending data to servers.

For maximum reliability, combine a third-party app with Do Not Disturb mode, for example, set Call Blocker to block all calls, and in system settings turn off notifications about missed calls.

5. Hidden settings of the engineering menu (for advanced)

On Xiaomi devices with Qualcomm processors (most Redmi and POCO models), you can turn off calls via the engineering menu, a method that requires caution, as incorrect settings can disrupt network operation.

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 "Set preferred network type" section.
4. Select LTE only (if you don’t have one, try LTE/WCDMA, but it’s less reliable).
5. Go back and restart your smartphone.

After that, the device will only work on the network. 4G, where voice calls are transmitted via VoLTE. If your carrier does not support VoLTE (or the function is disabled in the settings) SIM), The calls won't reach and the internet will stay. To check for VoLTE support, go to Settings. → SIM-maps and mobile networks → [Yours. SIM] → VoLTE and turn on the option.

If the Internet goes missing after this manipulation, return the settings to the original state and try another method. Also note that some firmware may block the engineering menu - in this case, use the MTK Engineering Mode application (for devices on MediaTek).

💡

The engineering menu is a powerful tool, but changing the network settings can lead to a loss of connection. Always write down the original settings before changing them!

6.Alternative solutions: second SIM, eSIM and physical lock

If software methods don’t work, consider hardware solutions:

• 📱 Second second SIM-map: Use one SIM It's only for the Internet (with a data-only tariff), and the second one for calls, turning it off as needed. On Xiaomi with two slots, this is done in Settings. → SIM-maps and mobile networks → [Choose. SIM] → Shut down.
• 🔗 eSIM: Some models (Xiaomi 13, POCO F5) It supports eSIM. You can create a virtual SIM only for the Internet (for example, MTS or Beeline) and use it in parallel with the physical SIM call-in.
• 🔌 Physical lock: Buy an adapter for SIM-Disconnect cards (sold on AliExpress) that lets you mechanically disconnect the connection without retrieving the card.

For owners of Xiaomi with support for Dual 4G (simultaneous operation of two SIMs in 4G), you can configure one SIM only for data, and the second one for calls only, disabling it if necessary.

1. Go to Settings. → SIM-maps and mobile networks.
2. Select SIM for calls and disable Mobile Data for it.
3. For the second SIM, turn off Voice Calls, leaving only Mobile Data.

This method is ideal if you need to alternate between Internet Only and Internet + Calls modes without constant settings.

Frequent problems and their solutions

Even after you set it up properly, you can have problems, and let's look at the typical scenarios and how to fix them:

• 📶 Internet disappears after call is turned off: Check if traffic saving mode is enabled in Settings → Battery and performance → Save traffic: Reboot your smartphone – sometimes the network will wilt after changes. Make sure the operator has no restrictions on data transfer without voice services (relevant for Yota and some virtual operators).
• 📞 Calls still pass: If Do Not Disturb mode is used, check for exceptions — maybe Repeat Calls or Favorite Contacts are enabled. For third-party blockers, update the number database (in Truecaller, this is done manually in the settings). If voice services are disabled, but calls reach - the operator has forced VoLTE activation. → SIM-map → VoLTE.
• ⚡ Battery goes down quickly: Turn off background call blocker activity in Settings → Annexes → Permits → Autostart. If you use the engineering menu, return the network settings to their original state. Forced. LTE increases energy consumption.

⚠️ Attention: On devices with MIUI Global Stable after major updates (e.g., with a MIUI 13 on MIUI 14) Call blocking settings may be reset. Always check them after the firmware upgrade.

If none of these methods worked, it could be the operator's policy, for example, MegaFon, at some tariffs, blocks data transmission if voice services are disabled, in which case it is only necessary to use Wi-Fi or change the operator.
