How to turn off calls on Xiaomi, saving the Internet

The modern smartphone, especially the popular Xiaomi, is often used not only for communication, but also as a powerful multimedia center or work tool. Many users face a situation when you need to stay online to receive messages in messengers or work on the navigator, but you want to completely eliminate the possibility of incoming voice calls. This can be due to the desire to take a break from intrusive conversations, the need to focus on an important task, or simply the desire to save battery power, as the constant search for the GSM network consumes energy.

The Android operating system in the shell of MIUI or HyperOS provides flexible tools for communication management, but not all of them are obvious at first glance. Standard mode "Do not disturb" often blocks only sound, skipping calls, and a complete disconnection of communication cuts off the Internet. In this article, we will discuss proven methods to isolate voice communication, leaving data channels active for your applications.

There are several effective ways to solve this problem, ranging from operator software settings to deep system configurations, and the choice of the specific method depends on your Xiaomi model, firmware version, and device usage goals. It is important to understand that the complete technical separation of voice and data channels in one SIM-The map requires a careful approach to network settings.

Use of forwarding and operator services

The most reliable and clean way to disable incoming calls without affecting mobile internet is not in the phone settings plane, but in the services of the mobile operator. The mobile network is originally designed so that channels for voice and packet data (GPRS/EDGE/3G/4G/5G) can be managed independently. Using the forwarding service allows you to redirect all incoming calls to another number or voicemail, leaving your phone formally available for data traffic.

To activate this function, you do not need to climb into the wilds of the smartphone menu. USSD-codes that work on any device, whether it's a budget Redmi or a flagship Xiaomi.codes may vary depending on your region and provider, but the standard protocol is GSM For example, activating unconditional forwarding to a number that doesn't exist or is occupied effectively blocks calls for you, but does not affect your call. LTE-linkage.

⚠️ Attention: Call forwarding service may be paid depending on your operator's tariff plan. Before activating the codes, specify the cost of a minute of forwarding or subscription fee for the service in your personal account or at the support service.

The alternative is to use your carrier's application. In modern "clients" from MTS, Beeline, Megaphone or Tele2, there is often a "Services" section where the forwarding or blocking of incoming is managed through a user-friendly interface. This is safer than entering random codes, and guarantees that you do not turn off the extra. Once set up, the network will see your phone as registered in a packet-switched domain, but ignore requests for a voice channel.

Setting up the “Do Not Disturb” mode in MIUI and HyperOS

The Do Not Disturb (DND) mode built into Xiaomi’s shell is a powerful tool, but its standard settings are often not flexible enough to completely ignore calls while keeping the Internet intact. By default, this mode only drowns out sound and vibration by letting calls onto the screen. However, if you configure exceptions correctly, you can achieve an effect where the phone does not respond to incoming signals at all, although the Internet connection will remain stable.

To get a deep setup, go to Settings → Sound and Vibration → Don’t Disturb. Here you are interested in “Repeat Calls” and “Allow Notifications.” If you turn off all permissions for calls and select an option where the phone doesn’t respond even to a repeat call from the same subscriber, the device will stop making sounds. However, fully locking the call screen often requires activation of the “Block Unknown Numbers” function in conjunction with the DND, or using more radical methods described below.

• 📱 Open Settings and find the Sound and Vibration section.
• 🔇 Select Do Not Disturb and activate the schedule or manual activation.
• 🚫 In the exception settings, remove the ticks from all contact categories so that calls do not pass.
• 📵 Make sure the Repeat Calls option is also disabled to ignore persistent subscribers.

Importantly, new versions of HyperOS have redesigned the logic of notifications and calls, so that Do Not Disturb mode can work in conjunction with script profiles, so you can create a Job or Photo scenario that automatically turns on DND and limits the background activity of applications, leaving only mobile Internet for instant messengers active, and this allows you to create the perfect conditions for concentration without breaking the connection with the digital world completely.

Use the shortcut in the notification curtain to quickly turn on the Do Not Disturb mode so you don’t search for it every time in the depths of the settings menu.

Disabling voice roaming and network type

One of the technical but very effective ways to separate voice from data is to manipulate the type of network. 4G (LTE) and 5G Voice and data are transmitted using different protocols (VoLTE vs. conventional) IP-If you force your smartphone to switch to a mode where only batch data is supported, or disable voice services in a particular communication standard, calls will stop coming.

To do this, go to the engineering menu or advanced settings SIM-The path usually looks like this: Settings. → SIM-maps and mobile networks → Type of preferred network: If you select the option "Only" LTE" or "Only." 5G" (if available, and your carrier or plan does not support VoLTE (Voice over) technology LTE) In this location, voice calls will be blocked at the network level, as the phone will not be able to “roll back” to the network. 2G/3G The Internet will continue to work at high speed.

⚠️ Note: This method works in unstable areas with poor coverage 4G. If the signal LTE the phone may lose the Internet, and the ability to receive calls, as it will not be able to switch to the Internet 3G. Use this method only with a confident signal.

Another thing is to turn off voice roaming. If you're on a trip, turn off the voice roaming option in your settings. SIM-maps (Settings) → SIM-map → [Yours. SIM] → Voice roaming will prohibit other operators from registering on the networks for voice calls. Mobile Internet for international data roaming (if it is enabled separately) may continue to work, although this depends on the specific conditions of your tariff and the roaming partner.

Blocking through the Security app and blacklist

Each Xiaomi smartphone has a Security system application preinstalled, which includes antivirus, cleaner and, importantly for us, call blocker functionality, which is a standard solution developed by the manufacturer itself, so it works more stable than third-party counterparts and has deep access rights to the telephony system.

To block all incoming numbers, you can use the Blacklist function. The logic is simple: you blacklist all possible number formats or activate the Block All mode if this option is available in your firmware version. In the Security section → Antiispam → Blacklist, you can configure rules. For example, you can block all hidden numbers or all unknown contacts. If you need to block absolutely everything, including familiar numbers, you will either have to add them to the list or use the Do Not Disturb mode in conjunction with this functionality.

The Security app also allows you to create lock schedules. You can set the call blocker to automatically turn on from 9:00 to 18:00 on business days, during which time the phone will drop calls, sending the caller a signal "busy" or "unavailable", but background processes such as downloading mail or synchronizing the cloud will work smoothly, which is ideal for those who want to keep control of the situation without unnecessary movements.

Third-party applications for call management

If Xiaomi’s built-in tools aren’t enough, specialized apps from the Google Play Market come to the rescue, offering more flexible lock scenarios that may not be available on stock firmware, and popular solutions like Call Blocker, Should I Answer?, or Blacklist allow you to create complex rules, such as blocking calls only on certain days or when you’re in a specific geolocation.

However, when installing such programs on Xiaomi, you need to be very careful about the permissions. The MIUI system aggressively unloads the background processes to save energy, so the blocking application can simply "sleep" at the right time.

• 🔋 In the battery settings, select the application and set the "No restrictions" mode".
• 🔒 Lock the application in memory (lock in the list of running applications) so that the system does not close it.
• 📞 Give full rights to call management and access to contacts.

Using third-party software gives you the advantage of having detailed statistics, where you can see who tried to reach you when, and it's a useful function for monitoring. But remember, these apps work at the device level: when a call comes, the phone picks it up, picks it up, picks it up from the database, and then resets it, which means that the caller's beeps will still be, unlike network-level forwarding.

Flight mode with selective Wi-Fi inclusion

The most radical, but often the most effective method for situations where only Wi-Fi Internet is needed and the mobile network must be completely dead is flight mode. Although technically it turns off all radio modules, modern Xiaomi smartphones have the ability to quickly turn on Wi-Fi even in active flight mode. Mobile Internet (LTE/3G/2G) remains off, which ensures that no incoming calls and SMS are available.

The algorithm is simple: turn on Flight Mode (airplane) in the notification curtain (4G, 5G, R's going to disappear. Immediately after that, click on the Wi-Fi icon to turn it on again. The system will allow this action. As a result, your phone will be connected to the wireless network, working like a tablet: messengers, mail, browser — everything works, but the number SIM-The card is completely inaccessible for voice communication.

This method is especially useful at night or in places where only EDGE catches, which puts the battery down quickly, but you need Wi-Fi to make Internet calls (WhatsApp, Telegram). You are completely isolated from the cell tower, keeping the connection to the router. This also helps in situations of low signal, where the phone constantly jumps between communication standards, warms up and discharges.

⚠️ Note: When using flight mode, you will not be able to receive SMS, including confirmation codes from banks. If you need SMS, this method will not work - use forwarding or settings. DND.
