How to disable incoming calls on Xiaomi: all ways to block

Modern Xiaomi smartphones, which are based on the shells MIUI or the new HyperOS, provide users with a wide range of tools for communication management. In some life situations, there is an urgent need to completely or selectively limit the flow of calls, this can be due to the desire to take a break from the noise, the need to focus on important work or blocking intrusive spammers and scammers.

The procedure for disabling incoming connections is not always obvious to the average user, since manufacturers hide these functions in different sections of the menu. There are several effective methods, each of which solves a specific problem, from temporary unavailability to permanent locking of certain numbers. Understanding the differences between these modes will allow you to flexibly manage your communication space.

In this article, we will take a look at all the available methods, including standard system settings, third-party applications and operator-specific codes, learn how to set up Do Not Disturb to skip calls from selected contacts, and how to activate On-Air mode without losing Wi-Fi access.

Use of Do Not Disturb mode for selective locking

One of the most flexible tools in Xiaomi’s arsenal is the Do Not Disturb (DND) feature, which, unlike full lockdown, allows you to create a “white list” of contacts whose calls will take place even in silence, ideal for nighttime or important meetings when you need to cut off the excess, but stay in touch with loved ones.

To activate this option, you need to go to Settings and find the Sound and Vibration section. Here you should select Do Not Disturb. The system will offer several preset scenarios, such as "Sleep" or "Meeting", but for deep customization, you better choose "Add a rule" or "Setting a schedule." In this menu you can set a time frame when the function will be activated automatically.

Special attention should be paid to the section "Allow calls", which is where traffic filtering is set up, you can choose the option "Contacts Only" or "Favorites", which guarantees that calls from the right people are missed, all other subscribers will hear the signal "busy" or horns, depending on the operator's settings, and your phone will remain calm.

• 📱 The mode allows you to create flexible schedules for automatic switching on.
• 🔇 Notification sounds and vibrations are turned off completely, the screen does not light up.
• ⭐ Ability to skip repeated calls from one number within 15 minutes.

⚠️ Note: In some versions MIUI Do Not Disturb settings may be reset after the device is restarted. It is recommended to check the status of the function after each system update or smartphone restart.

It's important to note that DND mode affects not only voice communication, but also app notifications. If you want messengers to keep running but calls are blocked, make sure that the exceptions include the necessary programs. It's a fine-tuning that requires careful attention, but the result is worth it.

Complete lock through air mode with Wi-Fi saving

When you want to have a full cellular connection but need internet access, the standard In-Airline mode seems too radical, as it shuts down all radios. However, on Xiaomi smartphones, there is a useful modification to this scenario to keep Wi-Fi active.

To implement this scheme, first activate air mode through the notification curtain or the Settings menu → Connections and Sharing → Air mode. Communication will disappear completely. Immediately after that, manually turn on the Wi-Fi module. The smartphone will restore the connection to the wireless network, but the SIM card will remain disconnected from the operator's base stations.

This method is often used by travelers who want to avoid roaming costs, or users who are looking for maximum peace of mind, incoming calls in this case can not physically reach the device, because the cellular module is deactivated at the system level.

Settings → Connections and sharing → Air mode → ONLINE → Wi-Fi → ONLINE

• ✈️ Completely eliminates the possibility of incoming voice calls and SMS.
• 🌐 Save access to Internet services, VoIP calls (WhatsApp, Telegram).
• 🔋 Significantly saves battery power by disabling network search.

💡

If you use this method frequently, add the Air Mode widget to your desktop for a quick one-touch switch.

It's worth remembering that when you're in active air mode, you won't get an emergency call, either, which is a critical point to remember when you're going camping or in places with unstable connections, where the phone can spontaneously switch to this mode when the battery is running low.

Set up blacklists and block specific numbers

If your goal is not complete isolation, but protection from specific stimuli, such as spam, collectors or former partners, then the security functionality in the MIUI shell will be the best solution.

To get started, open the Security app (green zipper icon) and search the Blacklist section in the menu, where you can manually add a phone number, select a contact from a phone book, or even block all hidden numbers, and the system automatically drops calls from listed subscribers.

The feature of the implementation in Xiaomi is that blocked calls can either be reset immediately or simulate the beeps for the caller before interrupting.This is configured in the menu of blacklist parameters.

It is important to update the spam databases in the Security app regularly, and to do this, go to the anti-terror settings and click "Update" to allow the system to recognize and block new fraud numbers that are constantly changing.

Call forwarding as a method of total disregard

A radical way to solve incoming calls is to set up unconditional forwarding, in which case all calls coming to your SIM card are redirected to another number, such as voicemail, a helpline, or a fictional number that does not exist.

You can configure this function through the standard Phone app. Click on three dots in the corner of the screen, select Settings, then Accounts for calls (or just the name of the operator). In the menu that opens, find Call Redirect. Here, select All Voice Calls and enter the number to which the calls will go.

An alternative and often more reliable method is the use of USSD-They work at the operator network level, so even if the phone is off or out of reach, the redirect will continue. The activation code is usually **21* number phone#, but you'd better check the current code with your provider.

• 🔄 Calls are redirected before the phone starts ringing.
• 📞 You can configure forwarding only when you are busy or have no response.
• 💰 The service can be paid depending on the tariff plan of the operator.

⚠️ Note: When actively redirecting to another mobile number, incoming calls may be charged according to your carrier's rates. Be careful when redirecting calls to other carriers' numbers or overseas numbers.

Using redirects is "heavy artillery," which is useful in the long run if you change your number, for example, but want to take calls to your old one, and for temporary rest, this method can be redundant and financially costly.

Blocking through the Security and Antispam app

In the Xiaomi ecosystem, Security is the central hub for banning, combining antivirus, memory cleaner and, importantly for our theme, a powerful call filter, and deep integration of the app allows you to block calls more efficiently than standard Android tools.

In the Antispam section, you can block not only by number, but also by category. The system is able to analyze incoming traffic and mark calls as Advertising, Fraudsters or Delivery. If you turn on the appropriate switches, such calls will automatically be reset, even if the number is not in your personal database.

It also has a silent mode feature for strangers, so you can set your phone so it doesn't ring or vibrate at all when you call from a number that's not in your contacts, and you'll hear the horns, but you won't know until you check the missed log.

For fine-tuning, go to Settings (the gear inside the Antispam app), where you can allow contact calls, repeat calls (if a person calls a second time in 3 minutes, it means something urgent) and calls from selected groups, which creates layered protection for your personal time.

• 🛡️ Blocking entire categories of rooms (taxis, couriers, sales).
• 🤫 Ability to completely hide the fact of the call from strangers.
• 📊 Maintaining statistics of blocked threats.

💡

The “Security” app on Xiaomi takes precedence over the standard Google call, so the lock settings should be checked in it.

Remember that spam databases require periodic updates, and in the face of constantly changing phone numbers, the relevance of the database is a critical factor in the effectiveness of protection.

Problem Solving: Why are the calls still going away?

Sometimes users are faced with a situation where it seems that all the settings are correct, but the phone continues to ring, most often the problem lies in the conflict of settings or the peculiarities of the work of telecom operators, let us examine the main reasons and ways to fix them.

The first reason is app duplication. Modern Xiaomi often has two callers installed: the standard one from Google and the branded one from MIUI. If you set up a lock in one, but the incoming call is handled by the other, the lock won't work. Check which application is installed by default to make calls in the Settings menu → Apps → Application Management → Three dots → Default Apps → Phone.

The second reason is operator settings: some services, such as Anti-Determinator or corporate rates, may take precedence over phone settings, in which case no manipulation of the smartphone will help, and you will have to contact the provider's support service to disable the service or set up a redirect on their side.

The third reason is Pocket mode, or random taps, and sometimes the phone gets pulled out of your pocket and the proximity sensor doesn't have time to respond by dropping a call or accepting it, and it's also worth checking if you've added a disturbing number to Favorites or contacts with a special sound profile that ignores Do Not Disturb mode.

Competent management of incoming calls on Xiaomi is not just a technical setup, but a way to improve the quality of life. By combining these methods, you can create a personalized filter system that will miss only the really important and sift out information noise. Regularly check system updates, as with each release of HyperOS and MIUI security functionality becomes more and more advanced.
