Many Xiaomi smartphone owners face an unexpected problem: mobile Internet suddenly stops working, although the balance is positive, and the network signal is stable. Often the reason for this behavior is the built-in “Traffic Limit” function, which is activated by default by the system to protect the user from overspending megabytes. In the MIUI shell, this mechanism can be set too aggressively, blocking the connection when a certain threshold is reached, which the system sets arbitrarily or based on old settings.
Disabling this restriction is not a difficult process, but it requires care, since the settings menu in different versions of the firmware can differ in the location of elements. Traffic control is an important part of the Xiaomi security ecosystem, but for users with unlimited tariffs or Wi-Fi connected, it becomes only an unnecessary obstacle. In this article, we will discuss all the nuances of disabling limits, resetting statistics and setting rules for individual applications.
It's worth noting that ignoring these settings can cause background processes like syncing photos or receiving instant messenger notifications to be suspended by the system. MIUI aims to extend battery life and save your money, but sometimes that concern becomes excessive. Let's figure out how to take back full control of your device's network connection.
The purpose and mechanism of the restrictions in MIUI
Xiaomi’s system traffic control mechanism is designed to prevent unforeseen mobile costs. The algorithm runs in the background, counting the amount of data transmitted and received via the SIM card. When the meter reaches the bar set by the user or system, the connection lock is activated automatically. This is a useful feature for those who use prepaid rates with a small amount of gigabytes, but it often interferes with the normal operation of the smartphone.
It is important to understand that the limit can be set on both the total amount of data per month and the real-time transfer rate.In some cases, the system may misinterpret app updates or heavy page loads as abnormally high consumption. Google services and other system processes can quickly exhaust the limit if it is set too low by default.
⚠️ Before completely disabling the limits, make sure that your plan does allow unlimited Internet use. Otherwise, you risk getting an invoice with a significant amount from the carrier.
The control mechanism is closely integrated with the Security app, which is the central control node, and it's through this tool that you monitor and apply constraints, and understanding the logic of how this component works will help you flexibly customize your device to your needs without turning off the fully useful security features.
Step-by-step instructions for disabling the traffic limit
To unlock Internet access, you need to go to the appropriate settings menu. The process does not require root rights or a computer connection, all actions are performed directly on the smartphone screen. First, open the Security app (green shield icon), which is pre-installed on all devices of the brand. This is a system tool that can not be removed, but can be configured.
Inside the app, find the data section, depending on the MIUI version and regional firmware, it can be called Traffic, Data Transfer, or Statistics. Clicking on this section will take you to the detailed cost management menu, and here we are interested in a button or link called Settings (usually as a gear) or the item "Limit traffic".
☑️ Limit-off algorithm
When you go to the limit menu, you'll see a switch that activates or deactivates the control function. The limit is turned off by simply moving the slider to an inactive state. The system can request confirmation of action, warning of possible financial risks. Accept the warning if you are confident in your plan.
If the standard path through the security app doesn't work for some reason or the interface is different, you can search by phone settings, type the word "traffic" or "limit" in the search bar, and the system will prompt you to go to the desired menu, this is especially true for newer versions of firmware, where the menu structure often changes.
Set up rules for individual applications
Often users don’t want to turn off the restrictions for the entire device, but only for specific programs. For example, a navigator or messenger needs constant access to the network, while games or social networks can wait. MIUI allows you to create flexible rules that ignore the overall limit for selected applications.
In the same traffic management menu, find a list of installed programs, usually sorted by data consumption or alphabetically, select the desired application, such as Telegram or Yandex.Navigator, and inside the application card will be a section "Restriction of traffic" or "Network restrictions".
Here you can allow an app to use mobile internet even when you reach a general limit, and there is also a service-specific “Unlimited Traffic” feature available if your carrier provides such an option, but in the context of phone settings, this means ignoring the internal MIUI counter.
- 📱 Messengers: Always keep active for WhatsApp, Viber and Telegram to keep important messages out.
- 🗺️ Navigation: Maps require a permanent connection to build a route and account for traffic jams, turning off the limit is critical.
- 🎵 Streaming services: Music and video consume a lot of traffic, so it is better to limit them if you do not have unlimited rates.
This selective setup allows you to maintain a balance between cost and functionality: You protect yourself from the accidental “eating” of traffic with heavy applications, but leave the communication channel open for important tasks.
Resetting statistics and calibration of the counter
Sometimes the problem with blocking the Internet is due to an error in the counting of data, the meter can "remember" old values or work incorrectly after changing the SIM card, in which case, even with a disabled limit, the system can behave unstable, the solution is a complete reset of traffic statistics.
To do this, go back to the main traffic control menu. At the top of the screen or in the settings menu (three dots or gears), find the item "Statistics" or "Reset statistics." Confirm the action. This will zero all the meters, and the system will start counting again from now on.
Resetting on the first day of the new billing period (the day of charge-off from the operator) will help synchronize the data on the phone with the data of the operator, which will simplify the control of costs in the future.
| Parameter | Description of action | Recommended frequency |
|---|---|---|
| Resetting statistics | Resets the counters of incoming and outgoing traffic | Once a month (on the day of the tariff update) |
| Limit check | Control of the set bar in MB/GB | When changing the tariff plan |
| Calibration of the date | Setting a date for the start of a new period | Monthly |
| Monitoring of background processes | Checking Hidden Traffic Consumption | Suspected leak |
After resetting, make sure that the new period starts correctly, which can be done in the tariff plan settings within the security application, specify the day your carrier is charging and upgrading its Internet packets.
The impact of the savings regime on the network
Beyond a clear traffic limit, the Internet can be affected by energy saving mode: In an attempt to keep the battery power, Xiaomi aggressively restricts the background activity of applications, which is often perceived by users as a lack of Internet. Although formally the traffic limit has nothing to do with it, the result for the user is one – no data is transferred.
There are several modes of operation in the battery settings (“Security” → “Battery”). In Saving or Ultra-Saving mode, the system can completely turn off data transfer in the background or when the screen is off. To avoid this, add the necessary applications to the exception list or switch to Performance or Balanced.
Also worth checking is the DLMM (Dynamic Link Management) settings, or similar network optimization features, which can limit the speed or frequency of network access to save charge, and disabling these features can increase battery consumption, but ensures a stable connection.
⚠️ Warning: Turning off the energy saving for background processes significantly increases battery consumption. If you use this setting, monitor battery levels throughout the day.
Users often confuse these two types of restrictions: traffic limit (financial aspect) and activity restriction (energy aspect).
Solving problems with displaying settings
In rare cases, users are faced with a situation where the traffic settings menu is not available, items are hidden or settings are not saved after a reboot, this may be due to errors in the operation of the system application “Security” or conflicts after a firmware update.
The first step in solving this problem is to clean the cache and data of the security application itself. Go to Settings → Apps → All apps, find Security (or Security) and select Clear Data. Fear not, this will not delete your personal files, but reset your antivirus and traffic control settings to factory values.
If the problem persists, it is possible that the device has third-party cleaning applications or antiviruses that conflict with the system functions of MIUI. Try to remove third-party software and check the network. It is also worth checking for system updates, as newer versions of MIUI often fix such bugs.
- 🔄 Update components: Go to the Security app, click on the user profile and check for updates for all components (antivirus, cleaning, traffic).
- 🔍 Search for hidden settings: Use a global search in your phone’s settings for “data usage” to find hidden menus.
- 🛠️ Network settings reset: In extreme cases, you can reset your network settings (Wi-Fi, mobile network, Bluetooth), which often solves connection problems.
In most cases, rebooting the device after making all the changes is a must-do step for the new traffic filtering rules to apply.
