Xiaomi’s current MIUI or HyperOS smartphone is a complex ecosystem that constantly requires network connectivity to synchronize data, update widgets and run background services. However, there are often situations when the user needs to completely isolate the device from the global network, whether it is saving battery power, lack of coverage or a desire to limit access to personal data. Owners of Chinese brands often face intrusive advertising in system applications, and disconnecting the network is one of the radical but effective methods of combating this phenomenon.
The procedure for deactivating data transfers can vary depending on the version of the Android operating system and the specific model of your gadget, whether it is a budget Redmi or flagship Xiaomi. In this article, we will discuss in detail all possible ways to break the connection, from standard switches to deep settings of access points. You will learn not only to turn off communication modules, but also to manage them with maximum efficiency for your tasks.
It's worth noting that a complete shutdown affects messaging, navigation, and cloud storage. It's important to make sure you have all the necessary offline maps or contacts in advance so you don't lose access to critical information at the right time. Let's look at the basic methods of managing network connections.
Using flight mode for rapid isolation
The fastest and most versatile way to completely break all wireless connections is to activate flight mode, which, when enabled, forces the system to shut down cellular, Wi-Fi and Bluetooth modules simultaneously, ideal for instantly stopping data transmission or saving battery power in a weak signal environment.
To activate, you just need to unlock the screen and swipe from top to bottom to open the notification curtain. In the Control Center menu, you need to find an icon with an image of the aircraft. Pressing it will change the color of the indicator, signaling the device to go offline. In some versions of the MIUI shell, when this mode is turned on, the system may ask for confirmation of action.
⚠️ Warning: Incoming calls and SMS are not working in flight mode, and if you are waiting for an important call, this method may not be the most suitable, as you will become inaccessible to subscribers.
An interesting aspect is that you can flexibly configure this mode, so once you activate the plane, you can manually turn back Wi-Fi or Bluetooth, while leaving the mobile network off, and you can use wireless headphones or home Internet without spending minutes and gigabytes from the operator.
Disconnecting the mobile Internet through settings
If you need to leave the possibility of calls and receiving SMS, but you need to block mobile traffic (3G/4G/5G), You should take advantage of the settings. SIM-This method is useful when you are roaming or want to avoid accidental traffic consumption when a bad signal is used.
To perform the operation, go to the Settings menu and select the item SIM-Maps and mobile networks. This shows all the SIM cards installed in the device. Select an active card and find the Mobile Internet switch. Putting it inactive (gray) will completely stop the data transfer through the carrier.
In older versions of firmware, the path may vary slightly: Settings → Connections and Sharing → Mobile Network. In this section, you can also find the option “Preferred Network Type”, where you can select 2G Only mode, which will significantly slow the Internet down, making it almost impossible to use, but leave communication available.
☑️ Checking network settings
It's worth remembering that disconnecting mobile internet doesn't affect Wi-Fi. If you're connected to a wireless network, apps will continue to load content, so you need to control both parameters to be completely isolated in transit.
Wi-Fi connection management and hidden settings
The wireless network management in Xiaomi smartphones is implemented quite flexibly, allowing not only to turn on and off the module, but also to control the behavior of the device in familiar networks. Standard disconnection is made through the “curtain” or the Settings → Wi-Fi menu, where it is enough to transfer the slider to the “Off” position.
But there's a more advanced way to manage it, and in the Wi-Fi settings menu, if you click on the gear icon next to the connected network, you can find the "Auto Connection" option, and if you turn it off, the phone will stop automatically connecting to that router, even if the Wi-Fi slider is active, which is convenient for guest networks or networks with unstable Internet.
Also in Wi-Fi settings, there is often a Wi-Fi Assistant feature, which automatically switches the device to mobile Internet if the wireless signal becomes too weak, and turning it off is critical if your goal is to strictly control mobile traffic consumption and prevent background activation.
Blocking Ads by Disabling Access Points (APN)
One of the common reasons users are looking for ways to turn off the Internet on Xiaomi is to combat system advertising in standard applications ("Conductor", "Music", "Themes"). A radical but effective method is to remove or change the settings of the access point (APN).
To perform this operation, go to the Settings path. → SIM-maps and mobile networks → Access points (APN). Select your operator's active access point. You can change the setting here. APN, by typing in arbitrary text, or by removing the access point altogether (although the system can automatically restore default values when restarting).
A more elegant method is to create a new access point with the wrong parameters. Create a new APN, call it, for example, "NoInternet," and enter any set of characters in the APN field, such as block. Save the settings and activate this point. The phone will try to connect to a non-existent gateway, and the Internet will not work, although the 4G/5G icon will burn.
| Parameter | Value for locking | Description of effect |
|---|---|---|
| Name (Name) | NoInternet | arbitrary name for |
| APN | invalid | Incorrect gateway address blocks connection |
| proxy | 0.0.0.0 | Indication of a non-existent proxy |
| Type APN | default,supl | Leaving the standard types, but without a working gateway |
⚠️ Note: After resetting the network settings or updating the firmware, the standard access points may return.
Limiting application background activity
Sometimes you don't need to shut down completely, you just have to block specific applications from accessing the network. Android and the MIUI shell allow you to flexibly configure access rights for each software you install, which helps you save traffic and battery power without breaking the connection completely.
Go to Settings → Applications → All apps. Select the app you want from the list (like a heavy game or social network). Find Data Use or Traffic Consumption. Here you will see switches for Wi-Fi and Mobile data. If you turn them off, you will prevent the app from logging on even when your phone is online.
There's also a Traffic Saving feature in the general network settings, which when activated, blocks the background data transfer for most applications until you open them actively, except for messengers, so you don't miss important messages.
Solving problems with permanent networking
Users often experience the situation where the Internet on Xiaomi turns on on its own, despite manual shutdowns, which can be caused by system services, weather widgets, or the sync settings of the Google account and Mi Account.
Check your sync settings. Go to Settings → Accounts and Sync. Make sure that autosynchronization is disabled or limited to Wi-Fi only. It’s also worth checking the Date and Time settings – the enabled option “Auto-Time over Network” can trigger a short-term mobile internet turn on to match clocks.
Another reason could be smart scripts or automation, and if you've used third-party automation apps or built-in scripts in the Security app, check their launch conditions, and it might have a "Enable Wi-Fi" action when you connect to a specific location beacon.
