Many Xiaomi and Redmi smartphone users, when faced with mobile network settings, question the existence of an unlimited mobile Internet mode, which is often confusing, since formally there is no such switch in the system, but the functionality that allows you to maximize traffic or circumvent restrictions is implemented in a complex way, we are talking about a set of software algorithms for the MIUI shell (or HyperOS) and the specific settings of the APN access point.
Essentially, this term is used by enthusiasts to either optimize background data transfers to prevent gigabytes from being consumed inconspicuously, or to have custom configurations to distribute Wi-Fi without losing speed. A system-based approach to managing connections allows owners of brand devices to maintain high load speeds even at operator limits. It is important to understand that the Android operating system itself does not create traffic out of thin air, but can significantly affect how applications consume it.
In this article, we will discuss in detail the mechanisms of the network module of Xiaomi smartphones, explain what hidden functions are hidden behind marketing names, and provide instructions for manually configuring parameters to achieve maximum connection efficiency.
The concept of unlimited traffic in the shell of MIUI
When users search for unlimited internet on their Xiaomi menu, they often end up in the traffic statistics section. This is a powerful monitoring tool that allows you to set limits and warnings. However, if you dig deeper, it becomes clear that Xiaomi is implementing its own algorithms for data compression and traffic prioritization that work at the system level. This is especially true for models with budget processors, where optimizing network queries helps save battery power and modem resources.
The key here is adaptive speed control. The system analyzes user activity in real time: if you just read text in the messenger, the background processes of downloading app updates will be suspended or limited to a minimum speed. This creates the illusion that your tariff plan is stretched, allowing you to stay online longer than usual.
⚠️ Note: Enabling Traffic Saving mode in system settings may block push notifications from some apps before they open. Make sure that messengers that are important to you are added to the exceptions.
In addition, new versions of HyperOS firmware have a smart network switch. If the 4G/LTE signal becomes weak, but stable Wi-Fi is available (even with browser authorization), the smartphone can offer to use it, saving mobile megabytes. This hybrid operation of communication modules is the implementation of the concept of “unlimited” at the software level.
For advanced users, the “Game Acceleration” feature is also available, which not only prioritizes game traffic, but can also redirect requests through optimized servers, reducing ping and reducing data consumption on reconnections. This is especially useful for online shooters and strategies, where every kilobyte and millisecond counts.
Setting up an APN access point for maximum speed
The most technically sound way to affect the quality and, relatively speaking, “limitless” connection (in the sense of no artificial plugs on the part of the phone) is to manually configure the access point APN (Access Point Name). Many users leave default settings that the operator provides automatically, but they are not always optimal for the specific conditions of reception in your region.
To access these options, you need to go the Settings path. → SIM-maps and mobile networks → Choice SIM-map → Access points (APN). Here you'll see a list of available profiles, and creating a new profile allows you to set specific protocol parameters that can improve connection stability, such as changing the type of connection you have. APN With default,supl on default,supl,mcx,xcap sometimes helps activate hidden VoLTE and video calling functions that also consume traffic, but with higher priority.
The important thing is choosing the protocol. In the APN type field, it is often recommended to prescribe a value * or leave it blank for automatic determination, but in some cases, manually specifying ipv4;ipv6 helps avoid compatibility problems when switching between cell towers, which reduces the number of connection breaks, which visually feels like a faster and more continuous Internet.
☑️ Checking settings APN
There is a common misconception that changing the Proxy or Port field can give you free internet, which doesn't work on modern networks and only disrupts the connection, but cleaning those fields (if they have old values) can actually speed up the response of the network, as requests stop going through unnecessary gateways.
Comparison of network modes
Choosing the right type of network directly affects how fast your traffic is consumed and how stable the connection is. Xiaomi smartphones have a wide range of settings of the preferred type of network, understanding the difference between them will help you customize the device to your needs, whether it is maximum speed or maximum savings.
Below is a table showing the main differences between the modes available in the Preferred Network Type menu:
| Network mode | Maximum speed | Stability | Impact on the battery |
|---|---|---|---|
| 5G (SA/NSA) | Very high (1 Gbps+) | Low (in the coverage area) | High-end spending |
| 4G / LTE | High (up to 300 Mbps) | Medium | Average expenditure |
| 3G / WCDMA | Low (up to 42 Mbps) | Tall. | Low expenditure |
| 2G / EDGE | Very low (< 0.5 Mbps) | Maximum | Minimum expenditure |
5G mode is only justified in large cities with dense construction and good coverage. Otherwise, the phone will constantly search for the network, which will lead to fast battery drain and ping jumps. For most use cases, including high-resolution video streaming, LTE mode is the “middle ground”.
If your goal is to maximize battery life and you only need text (messengers, news), it makes sense to force the phone to 3G/2G mode. This will radically reduce the speed, but create the effect of “stretched” traffic, as the pages will load for a long time, and background processes will almost stop due to low channel bandwidth.
💡
To check the real speed of your connection in the current location, use the built-in “Security” → “Speed Test” application to avoid installing unnecessary programs from the Play Market.
Hidden Engineering Menus and Testing
For deep diagnosing Internet problems, Xiaomi has hidden menus available through a set of special codes in the Phone app, not a hack for free internet, but a professional tool for viewing real-world connection statistics and forced switching between towers.
The main code for logging into the engineering menu is ##4636##. Once you enter the Phone Information section, you can see detailed statistics: signal level in dBm, network type, cause of connection breakage. There is also the option "Turn off radio / Turn on radio" available here, which works more effectively than just turning on and off "Air mode" in the notification curtain.
The special thing that you should note is the Preferred network type inside this menu, which duplicates the system settings, but often contains additional options that are not available in the normal interface, for example, you can choose LTE only mode, which will cause the phone to ignore the 3G and 2G towers. In urban environments, this can stabilize the Internet by removing constant reconnections, but in the subway or outside the city, communication will completely disappear.
⚠️ Attention: Forced installation of the regime «LTE “only” through the engineering menu may result in the inability to make regular voice calls if your operator does not support VoLTE technology or it is not activated on the service. SIM-map.
You can also reset your DNS settings to Google servers (8.8.8.8), which sometimes helps you open websites if the provider is filtering or has problems with its name servers. However, for the average user, changing these settings without understanding the essence can lead to a complete loss of access to the network.
Managing application background traffic
Often, the feeling of an “end” of the internet comes from one or more apps quietly consuming gigabytes in the background. Xiaomi provides flexible tools to control this process, allowing you to actually create your own “no-limit” for important programs while limiting the rest.
Go to Settings → Apps → All apps, select the app you want, and find Traffic Saving or Data Use. Here you can disable background connection. This means that the app will only update content when you open it. For video services and social media, this is a critical setting.
There is also a global traffic limit setting, where by setting a monthly limit, the system will start to alert you to approach a threshold, and when it reaches a limit, it can completely disable mobile data, leaving only Wi-Fi available.
- 📱 Video services: YouTube, Netflix, TikTok – it is recommended to allow only over Wi-Fi or strictly control background activity.
- 💬 Messengers: Telegram, WhatsApp – require permission for background data to receive messages in a timely manner.
- 🎮 Games: PUBG, CoD Mobile – consume a bit of traffic, but are sensitive to the stability of ping, it is better not to limit the price of the product.
- 🗺️ Navigation: Yandex.Maps, Google Maps – can download maps and traffic jams, the consumption depends on the caching settings.
A separate point to mention is the Background Connection feature in the battery menu. If you notice that the phone is rapidly discharged and warmed, check this list. Often, voracious applications disguise themselves as system processes. Shutting down the Internet for suspicious programs is the first step to optimization.
