Xiaomi and Redmi smartphone users often face intrusive notifications that the mobile traffic limit has been used up, after which the Internet speed drops to a minimum or completely stops data transfer. This feature, built into the MIUI shell, is designed to save you money, but often works incorrectly, blocking access to the network even if there is a paid package of gigabytes. Traffic restriction can be set by the user himself accidentally, activated by the system economiser or be the result of a malfunction of the operator.
In this article, we will take a closer look at all the possible causes of blocking and provide step-by-step instructions for eliminating them. You will learn how to properly configure Settings → Network Connections, adjust APN settings and use hidden engineering menus to reset meters. It is important to understand that ignoring this problem can lead to the inability to use navigation, messengers and streaming services at the most inopportune time.
Before proceeding with radical measures, it is necessary to determine the source of the problem: software shell failure, operator error or physical damage. SIM-Diagnostics begin with checking the current state of the network and the data consumption settings in the system menu. We will look at both standard methods and advanced solutions through the system menu. ADB-commands if the standard interface does not produce the desired result.
Diagnostics and verification of the current network status
The first step should always be to check the current status of the connection carefully, because often the problem lies in the banal exhaustion of the operator's service package. Go to the Safety app (green icon with lightning) and select Traffic section. This displays detail by day and application, which allows you to understand which program consumes the most data. If you see that the meter reached the set limit, the system could automatically block further data transfer.
However, if your plan is unlimited or gigabytes are still left, it is worth checking the settings of the access point. APN Often, the phone thinks traffic is over, even though the operator is doing fine. Resetting the factory access point settings often solves the problem instantly. → SIM-maps and mobile networks → Access points (APN) and press the reset button in the menu.
⚠️ Note: Before making changes to the settings APN write down or take pictures of the current settings so that if necessary, you can return everything as it was if the provider uses specific settings.
Also, it is worth considering that some operators use Fair Usage Policy technology, reducing speed after reaching a certain threshold, even if the traffic is not formally ended, in this case, it is impossible to remove the restriction software on the phone - you need to connect a new service package from the operator.
Setup of the built-in MIUI traffic monitor
The MIUI shell and its new version of HyperOS have powerful built-in cost control tools that can be too aggressive by default. To remove artificial restrictions, go to the Security app and select Traffic. In the upper right corner, there is a gear icon that opens the settings menu. This is where the dog that bites the leg most often hides: the limit can be activated by default.
In the traffic settings menu, find the Traffic Limit and make sure the switch is off. If you need to leave control but remove the lock, select Warn instead of Shutdown. This will allow you to receive notifications about spending 80% or 90% of the packet, but will not break the connection. You can also set up a reset period, for example, on the 1st of each month, so that the meter does not accumulate indefinitely.
☑️ Checking the settings of the traffic monitor
The Traffic Saving feature in the Security app itself deserves special attention, and it can block background data transfers for certain programs, creating the illusion of no Internet. Go through the application list and convince!

Managing Restrictions for Individual Applications
Users often complain that the Internet is “not working” when in fact access is blocked only for a specific application, such as YouTube or Instagram. On the Xiaomi-based Android system, there is granular control for each software installed. Go to Settings → Applications → All applications, select the desired program and go to the Data Use section.
So here you'll see two important switches: Mobile data and Background connections. If the first one is turned off, the app won't have access to the Internet via the Internet. SIM-If the second one is turned off, the program won't be able to update or receive messages when the screen is off, which is a common reason why notifications come late.
- 📱 Make sure that the mobile data slider is activated for all necessary messengers and browsers.
- 🔄 Enable Background Connections for email clients and work applications so they are always online.
- ⚡ Check the No Limits mode (or Unlimited Traffic) that prevents the system from "killing" the application process to save energy.
There is also a global setting that can block the Internet for all new applications, located in Settings → Apps → Network Access (or through Network Access search), here is a list of all programs with two columns: Wi-Fi and Mobile Data, check if there are crosses or bans in the mobile data column for services that are important to you.
💡
Use search in settings: type the phrase “network access” into the settings search bar to instantly get into the application rights management menu for the Internet.
Reset network settings and APN settings
If the software settings inside the interface didn't work, you need to do a deeper reset of network settings. This action will return all communication, Bluetooth and Wi-Fi settings to factory values by removing saved passwords and access point configurations. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth.
Once reset, the phone will reboot and you will need to re-enter passwords from Wi-Fi networks, but this often solves problems with sticking in old carrier configurations that may conflict with new data plans. APN, If the automatic parameters are not applied.
| Parameter | Value for discharge | Note |
|---|---|---|
| Name (Name) | Operator (e.g. MTS) | You can ask any one. |
| APN | internet.mts.ru | Depends on the operator. |
| proxy | Not given. | Clear the field |
| Port port | Not given. | Clear the field |
| Type APN | default,supl | Standard value |
It is important to understand that for different operators (Beeline, Megafon, Tele2) parameters APN It is best to request the current settings on the official website of the operator or send a special USSD-requesting that the phone automatically receive the correct data.
⚠️ Note: Resetting your network settings will remove all stored Bluetooth devices and passwords from Wi-Fi, so make sure you remember the data to connect to your home network.
Use of Engineering Menu and ADB Teams
For advanced users who have not had the standard methods, there are deeper ways to intervene, one of which is to use the engineering menu available through the code ##4636##. In the menu that opens, select Phone information and scroll down to the Set preferred network type. Switching modes (for example, from LTE only to GSM/UMTS/LTE) can restart the communication module and remove the lock.
An even more powerful tool is the debugging of USB use ADB (Android Debug Bridge. You can connect your phone to your computer and send a command to reset the system-level traffic meters. USB" In the section For developers (to activate this section, you need to 7 times click on the build number in About phone).
adb shell pm clear com.android.settings
adb shell am broadcast -a android.intent.action.MAIN -n com.android.settings/.SubSettings -e :android:show_fragment:com.android.settings.network.NetworkProviderSettingsUsing ADB requires caution, because incorrect commands can lead to unstable system operation. This method is recommended only if you understand what you are doing and have a backup of data. Most often, the problem is solved at the level of user settings, and it is rare to resort to the command line, in case of serious firmware bugs.
💡
Using ADB and engineering menus are extreme measures that should only be applied with full confidence in your actions and the availability of a backup.
