Unlimited mobile Internet in the settings of Xiaomi Redmi: analysis of the function and hidden nuances

Xiaomi Redmi smartphone owners often encounter a mysterious option in their mobile network settings, “unlimited mobile Internet.” At first glance, the name promises unlimited traffic, but in practice everything is much more prosaic. This feature often causes confusion: whether it really distributes the Internet without restrictions, whether it is a marketing ploy, or even a technical bug. In this article, we will examine in detail what lies behind this setting, how it interacts with your operator’s tariff and why it is better not to touch it unnecesssarily.

Let’s warn you right away: the option is not related to the real unlimited from the mobile operator, its purpose is to control the behavior of the smartphone when working with mobile data, especially when roaming or connecting to networks with limited traffic. For example, if you are traveling abroad and using a local SIM-With a small packet of internet, Redmi can automatically limit background processes to save megabytes. Activating "unlimited" mode overrides these restrictions - but it's not always useful.

Next, we will analyze exactly where this setting is in different versions of MIUI, how it affects traffic and battery consumption, and also analyze the myths associated with “hidden unlimited” and pay special attention to the risks of overspending when roaming if the feature is configured incorrectly.

Where to set up unlimited mobile internet in Redmi

The path to the option may vary slightly depending on the MIUI version and the smartphone model, but the general logic holds, and in most cases it can be found as follows:

  • 📱 MIUI 12-14: Settings → SIM-maps and mobile networks → [choose SIM] → Unlimited mobile internet
  • 🔄 Old versions (MIUI 10–11): Settings → Wireless networks → Mobile network → Additional settings → Unlimited data
  • ⚙️ On some models (for example, Redmi Note 10 Pro): the option is hidden in Settings → SIM-map → [operator] → Network type (Installation "Additional»)

If you don't see this item, it's likely that your firmware version doesn't support it -- or it's hidden because of carrier policies, for example, on smartphones for the Chinese market (China ROM), this option may not be available at all.

📊 You found this setting in your Redmi?
Yeah, I found it easy.
No, I don't see her.
I don't know where to look.
I have a different brand of smartphone.

Important: Some devices have different names for the option, like "Unlimited Data" or "Background Limitation" (in reverse terms). If you have a two-sim Redmi, the setting can be duplicated for each device. SIM-map.

What does this function actually do?

Control of "unlimited mobile Internet" is not about the tariff, but about the management of background traffic, and when the option is disabled, the MIUI system automatically limits:

  • 🔄 Background synchronization (mail, messengers, cloud services)
  • 📥 Auto-update applications via mobile network
  • 🎵 Streaming music/video in low quality (e.g. YouTube or Spotify)
  • 📊 System checks for updates (including: MIUI Google Play)

When you turn on, all these restrictions are removed — the smartphone begins to behave as if it is connected to Wi-Fi. This is convenient if you have a really unlimited tariff, but dangerous in roaming or with a limited data package. For example, background synchronization of Google Photos can “eat” several gigabytes per night if the option is activated.

Technical details for advanced
When the option is on, the system MIUI Changes the priority of the network interface rmnet_data in the Android kernel, allowing low priority processes (e.g, bg_data) You can use the mobile network without restrictions. /data/system/netpolicy.xml, Where the rules for each type of traffic are specified.

The key is that the setting does not affect internet speed or circumvent operator restrictions, it only allows or prohibits Redmi from using the mobile network for secondary tasks. If your tariff limits speed after the packet is exhausted, turning on "unlimited" mode will not help.

When to turn on “unlimited mobile Internet”

There are several scenarios where activation of this option is justified:

  1. Real unlimited tariff: If your operator provides Internet without restrictions (for example, "Unlimited" from MTS or "All is possible" from Tele2), you can safely turn on the function - this will improve the work of background processes.
  2. Using a smartphone as an access point: When you distribute the Internet to other devices, Redmi can artificially limit speed if the option is turned off.
  3. Online games or streaming. For stable operation of PUBG Mobile, Twitch or YouTube in high quality, it is better to remove restrictions.
  4. Cloud services: If you frequently upload files to Google Drive or Mi Cloud over a mobile network, enabling the feature will speed up the process.

Even in these cases, however, there are pitfalls: for example, some operators block tethering on unlimited rates, and enabling the option can lead to automatic switching to paid roaming.

💡

Before you turn on the feature, check the terms of your tariff on the operator’s website. Some “unlimited” packages actually have a speed limit after a certain threshold (for example, 100 GB per month).

Risks and Side Effects: Why It’s Better Not Touch The Function

The main danger lies in uncontrolled traffic consumption, especially in roaming.

Use of the two SIM-card-rateMIUI can switch to second SIM for background if the main is limitedSet SIM Priority in Settings → Dual SIM

Another problem is increased battery consumption: When the background is not limited, the mobile module is more active, which reduces battery life by 10-15%. For example, on the Redmi Note 12 Pro+ with the option on and 5G active, battery consumption can reach 20-25% per hour.

⚠️ Attention: On some firmware (MIUI 13.0.4–13.0.6) was a bug that ignored operator restrictions and kept downloading data even at zero balance, resulting in a negative score.

Myths and misconceptions about the “unlimited” regime

There are a lot of myths about this feature on the web, and we'll look at the most popular ones.

  1. “This gives real unlimited” – no, the option only removes the MIUI restrictions on background traffic, but does not change the tariff conditions.
  2. “Increases Internet speed” – the speed depends only on the operator and network coverage, not on the settings of the smartphone.
  3. “Helps bypass operator restrictions” – Xiaomi does not have access to mobile servers, so it is impossible to bypass the locks.
  4. “You need to turn on for a stable connection” – on the contrary, in the zone of a weak signal, it is better to turn off the option to save battery power.

Another common misconception is that once you turn on the feature, the smartphone starts stealing traffic from other devices on the network. SIM-Maps or routers without your knowledge.

⚠️ Attention: In 2022, instructions were put on the network to crack this setting to obtain “hidden unlimited” all of which are frauds and can lead to blocking. SIM-Cards by the operator for suspicious activity.

Alternative ways to save traffic on Xiaomi Redmi

If you want to reduce the consumption of mobile Internet, but are not ready to completely abandon background processes, use these methods:

  • 📶 Data Saving Mode: Settings → Transfer of data → Traffic savings: compresses images and limits background activity.
  • 🔄 Restriction for individual applications: In the same section, you can disable mobile network access for unnecessary programs (e.g. Mi Video or GetApps).
  • 📡 Automatic Wi-Fi Connection: Enable Settings → Wi-Fi → Additionally. → Autoconnect to open networks (caution: only verified networks!).
  • 📊 Traffic Monitoring: Install an application like My Data Manager for detailed statistics on each application.

For owners of Redmi with MIUI 14, the Smart Savings feature (Settings → Battery → Saving Charge → Smart Saving) is available. It automatically limits background traffic when the battery is below 20%, which helps to extend the autonomy.

💡

If you use navigation frequently (e.g. Yandex.Maps or Google Maps), download maps in advance via Wi-Fi, which will reduce mobile traffic consumption by 5-10 times.
