How to turn off data transfer to Xiaomi Redmi 9

Xiaomi smartphone owners often face the need to temporarily restrict access to the Internet or completely turn off mobile traffic. For the Redmi 9 model, this is especially true, since the device can actively consume traffic in the background, even when the screen is off. Understanding how to manage network connections helps not only save money, but also significantly extend the battery life of the gadget.

There are several levels of data shutdown, from fast blocking through the notification curtain to deep tuning of system settings and access points. In this article, we will discuss all available methods that will allow you to fully control the network activity of your device, you will learn how to block access to individual programs and change the global network settings.

Control of the Internet connection becomes critical in roaming or using limited-bundle gigabyte fares. Incorrect settings can lead to unforeseen charges by the operator, so it is important to know where the switches are hidden in the MIUI shell and how they affect the operation of the system as a whole.

Quick shutdown via control panel

The easiest and most affordable way to stop sharing data with the network is to use a standard widget in the notification curtain, and you just swipe down the screen from top to bottom to open the control center, and you'll see a two-arrow icon that stands for "Mobile Data," and clicking on it changes the color of the indicator: if it's gray, the Internet is off, if blue or green is active.

However, this method has its own peculiarities depending on the firmware version. In some builds MIUI on Redmi 9 long-term press on this icon immediately throws the user to the extended menu of SIM card settings, which allows you to quickly check whether the mode is activated "Always on mobile data", which can ignore the standard switch.

It is worth considering that when you turn off the mobile Internet through the curtain, some system services may try to restore the connection, this happens if the smart switching function is activated in the settings, so to guarantee the result, it is recommended to combine this method with checking the list of applications that have access to the network.

• 📱 Swipe down from the top edge of the screen to open the curtain.
• 🔘 Find the Mobile Data icon (usually two up-and-down arrows).
• 🚫 Press once to deactivate (the indicator must go out).
• ⏱ To access the settings, press and hold your finger on the icon.

Therefore, for complete isolation of the device from the network, it is better to use deeper settings, which will be discussed later.

Deep tuning SIM-card

For more detailed control, you need to go to the system settings menu. MIUI: Open Settings, then select a section. SIM-This is where the main traffic control levers for each of the installed SIM cards are located, which is especially important for owners of the Redmi 9 versions with two slots.

Inside this menu, you'll find a "Use Mobile Data" switch that completely stops packets from being sent across the operator's network, but leaves voice and SMS available, and you can choose your preferred SIM card for the Internet if there are two, and set traffic limits when the system automatically blocks the connection.

⚠️ Attention: On the menu SIM-If it's active, the phone can turn on the Internet for a short time to check the mail or messengers, even if you turn off the main switch.

In addition, this section provides network type configuration. Switching from 5G/4G to 3G/2G can significantly reduce speed, but will not completely shut down data transfer. So, to completely block the data access switches, not changing the communication standard.

Access blocking for individual applications

Often, the user does not need a full offline, but only a ban on access to the network for specific programs. Xiaomi Redmi 9 has a powerful built-in tool for this. Go to the Security application (green icon with a shield), then select Data Transfer. Here you can see the full list of programs that consume traffic.

Clicking on any program on the list will get you into the network permissions menu. You can disable both mobile internet and Wi-Fi. This is the perfect way to stop intrusive ads in games or background downloads of social media updates without removing the apps themselves.

This method allows you to configure your device flexibly, for example, you can leave Internet access only for messengers and navigators, blocking all entertainment applications.

Set up an APN access point to lock completely

There's a radical method of shutting down the Internet that works even when standard switches are bugged or reset by the system. APN. To do this, you need to go to the settings. → SIM-maps and mobile networks → sim-card → Access points (APN).

Select your operator’s active access point. In the menu that opens, find the APN field (or “Access Point Name”). Change its value by adding any character at the end, such as a dot or the letter “x.” Save the changes with the “More” button (three dots in the corner) → “Save” button, and then select that changed point as active.

Old meaning: Internet.mts.ru


New value: Internet.mts.ru.x

Once this is done, the phone will try to connect to a non-existent address, and the data will not be transmitted, and this is a guaranteed way to avoid accidental traffic consumption, so to return the Internet, you just need to return the original value or select another, unchanged access point from the list.

• 🛠 Go to your mobile network settings SIM-map.
• 📝 Select "Access Points (APN)».
• ✏️ Edit the current point by changing the field APN.
• 💾 Be sure to click "Save" in the menu "More».

💡

Before you change the APN, take a screenshot of the initial settings, which will allow you to quickly restore Internet access if you forget the correct settings of your operator.

Flight mode and radio module control

Air mode is a heavy artillery in communications control, and when it is turned on on on Redmi 9, all wireless interfaces, mobile, Wi-Fi, Bluetooth and NFC, are completely turned off, which guarantees zero traffic consumption, but makes it impossible to receive incoming calls.

The convenience of MIUI flight mode is that it can selectively turn on modules, and by activating the flight, you can manually turn on Wi-Fi. In this state, the mobile Internet is guaranteed to be turned off at the radio level, and Wi-Fi is running normally, which is more reliable than just turning off the mobile data switch.

⚠️ Warning: When the air mode is on, the alarm continues to work, but notifications from messengers (WhatsApp, Telegram) will not come until you turn on Wi-Fi manually.

Using this method is especially useful at night or in places with extremely unstable signal, where the phone constantly “catch the net”, spending battery power on constant attempts to reconnect.

💡

Air mode with Wi-Fi enabled is the most reliable way to ensure that mobile traffic is not consumed, since the cellular radio module is completely powered off.

Background flow problems and their solution

Even after all the settings, users sometimes notice that traffic is still being consumed, often the culprit is Wi-Fi Assistant or Acceleration, which automatically switch the phone to mobile Internet if the Wi-Fi signal seems weak, and this feature is found along the way: Settings → Wi-Fi → Wi-Fi assistant.

Turn off the “Switch to Mobile Internet” option so your phone doesn’t use your gigabytes in the background. Also worth checking the Apps → Permissions → Auto Run. Many apps run themselves and start downloading updates, ignoring general restrictions unless explicitly prohibited.

Regular monitoring of statistics will help identify the traffic eater, you can see the exact timeline in the data usage section, if you see a spike in activity at 3 a.m. when the phone was lying idle, then some application is behaving incorrectly and requires restriction of rights.

• 📉 Turn off Wi-Fi Assistant in wireless network settings.
• 🔒 Stop Auto-Running Suspicious Apps.
• 📊 Check traffic statistics regularly.
• 🔄 Reset your network settings if the problem persists.
