Unlimited mobile Internet in the settings of Xiaomi: truth or deception?

Have you ever noticed the mysterious “Unlimited Mobile Internet” option in your Xiaomi smartphone settings? At first glance, it seems like a magic button that, when you click on it, traffic will cease to melt and speed will always be maximum. But is it really true?

In this article, we’ll look at what’s really behind the feature, how it works in MIUI and HyperOS, and why carriers are slow to tell users about it, how to turn it on or off, what Xiaomi models support it, and most importantly, whether it’s worth using it at all, so as not to get an unexpected bill for the Internet.

What is the “Unlimited Mobile Internet” in Xiaomi?

The name of the feature sounds promising, but in practice it is not a magical option that gives unlimited traffic.In reality, unlimited mobile Internet is just a MIUI setting that disables restrictions on the background use of mobile data for certain applications.

By default, Xiaomi (like many other vendors) restricts the background activity of apps over the mobile network to save traffic. But when you turn on this mode, the system allows applications (such as instant messengers, mail or cloud services) to sync, update and download data in the background without restrictions - as if you were connected to Wi-Fi.

• 🔄 Does it work on all models? Available on most smartphones Xiaomi/Redmi/POCO s MIUI 12 and newer (including HyperOS).

It’s important to understand that if you don’t have unlimited rates, turning on this option can lead to increased traffic consumption – especially if you have “gluttonous” apps like TikTok, YouTube or cloud backups installed.

Where is this setting in MIUI and HyperOS?

The path to function may vary slightly depending on the firmware version, but the general algorithm is as follows:

1. Open the Settings.
2. Go to Connections and Sharing → Mobile network (or SIM-maps and mobile networks).
3. Choose yours. SIM-card (if there are several).
4. Find Unlimited Mobile Internet (in some versions – Unlimited Traffic or Allow Background Data Use).
5. Move the slider to the position on.

On HyperOS (new firmware for Xiaomi 14, Redmi Note 13, etc.), the path may be a little different:

Settings → Mobile Network → Additional settings → Unlimited traffic

Make sure you have unlimited rates or a sufficient traffic package

Check which apps have access to mobile data

Turn off auto-update heavy apps (such as games)

Set limits for individual applications in “Data Use”

-->

If you can’t find this item, your version of MIUI may not support it, or the operator has blocked this feature at the firmware level (this happens on some branded builds for telecom operators).

How does the “unlimited internet” really work?

Let’s see what happens under the hood when you turn on this option:

Critical detail: this feature does not affect the operator’s restrictions: if you have a tariff with a limit (for example, 15 GB per month), then after it is exhausted, the speed will drop to 64-128 Kbps regardless of Xiaomi’s settings, but within the limit, applications will be able to consume traffic as if you are connected to Wi-Fi.

Example: if you have unlimited mode enabled, Google Photos can start automatically uploading all your photos to the cloud over the mobile network, and WhatsApp will sync media files in the background, which is convenient but can cause unexpected traffic waste.

💡

Before you turn on this feature, check which applications have permission to use data in the background. You can do this in Settings → Applications → Permissions → Data Use.

Which Xiaomi models support this feature?

Unlimited Mobile Internet* was introduced in MIUI 12 and is saved in newer versions, including HyperOS, but it depends not only on the firmware version, but also on:

• 📱 Smartphone models – on budget devices (for example, Redmi) 9A or POCO C50) It might not be.
• 🌍 Firmware region - in global (Global) and Chinese (China) versions MIUI The function can be called differently.

Here is a list of popular models that have this feature (tested on the latest firmware versions):

• Xiaomi 12/12 Pro/12S Ultra (MIUI 13–14)
• Redmi Note 12/11/10 Pro (MIUI 13–14)
• POCO F5/F4/X5 Pro (MIUI 14)
• Redmi K50/K60 Pro (MIUI 14 / HyperOS)

The advantages and disadvantages of using unlimited Internet

Like any feature, unlimited mobile internet has its advantages and disadvantages. Let's go through them in detail.

✅ Advantages

• 📲 Constant synchronization – instant messengers (Telegram, WhatsApp) and email are updated in real time, like on Wi-Fi.
• ☁️ Automatic backup – Google Photos, Mi Cloud and other cloud services will be able to download data without you.
• 🔄 Background updates – apps (such as Google Play or the App Store) will be updated automatically.
• 🎵 Continuous streaming – music services (Spotify, Yandex Music) will not be interrupted when the screen is blocked.

❌ Deficiencies

• 📉 Increased traffic consumption – unlimited tariff is mandatory, otherwise you risk being left without Internet by the end of the month.
• 🔋 Increased battery consumption – constant mobile network activity reduces battery life.
• 🛑 Risk of background activity of malicious applications – if there are viruses on the phone, they will be able to transmit data without your knowledge.
• 🌡️ Overheating of the device – heavy use of the mobile module can lead to heating of the smartphone.

The bottom line: the feature is useful if you have a really unlimited rate and are willing to put up with a slightly faster battery drain, otherwise it is better to keep it off and only turn it on when necessary (for example, on trips).

💡

If you have a traffic limit tariff, enabling "unlimited internet" can lead to additional costs.Always check the rest of the traffic in the operator's app!

How to optimize the use of the function so as not to waste traffic?

Even if you have unlimited rates, it is wise to set up unlimited mobile internet so that it does not eat traffic in vain.

1. Limit background traffic to unnecessary apps: Go to Settings → Apps → Data usage and turn off background activity for games, social media, and other “gluttonous” programs.
2. Configure app auto-update over Wi-Fi only: In Google Play → Settings → Auto-update apps, select Only via Wi-Fi.
3. Use Data Saving Mode: Turn on Traffic Savings in your mobile network settings – this will reduce consumption without completely shutting down background activity.
4. Track traffic consumption: In Settings → Connections → Data usage can be set a limit and notified when it is exceeded.

You should also pay attention to the settings of individual applications, for example:

• In Telegram, turn off Autoupload media in the mobile network.
• In Google Photos, select Download only over Wi-Fi.
• On YouTube, limit the quality of your video when viewed via mobile.

These simple steps will help you save traffic without giving up the conveniences of unlimited mode entirely.

💡

If you travel frequently, create a separate profile in your mobile network settings with “unlimited internet” turned off for roaming – this will save you from unexpected bills for traffic abroad.
