20 Band in Xiaomi smartphones: what it is, why you need and how to check support

If you’ve ever looked at the specifications of Xiaomi smartphones before you buy, you’ve probably seen the term “20 Band” mentioned in the network support section. For most users, this sounds like a set of numbers without making any clear sense, but it’s actually a critical aspect of mobile communication that directly affects signal stability, internet speed, and even battery life, a question that’s especially relevant for those who travel frequently or live in areas with unstable coverage.

In this article, we will discuss what the 20 Band (or LTE Band 20) is, why support for it is important in modern Xiaomi smartphones, and how the lack of this range can limit the capabilities of your device. Also, you will learn how to independently check whether your phone supports this range, and which Xiaomi models are guaranteed to work with the Band 20 in Russia and Europe. If you are planning to buy a new gadget or just want to optimize the current connection, this information will be useful.

What is the LTE Band 20 and why is it important?

The LTE Band 20 (or 800 MHz) is a band allocated for mobile communications in Europe and some other regions, including Russia, with a key feature being high signal penetration, which allows for stable coverage in dense urban areas, underground parking lots, remote rural areas or inside thick-walled buildings. Unlike higher frequency bands (such as Band 3 or Band 7), which provide high speeds but lose power quickly over distances, Band 20 is optimized for broad coverage and sustainable connectivity.

In Russia, this range is actively used by operators Beeline, MTS, MegaFon and Tele2 to expand the coverage of 4G. For example, if you live in a private house outside the city or often visit the subway, Band 20 support in your Xiaomi can be a decisive factor between a stable Internet and constant communication interruptions. Without this range, the smartphone will be forced to connect to less reliable frequencies, which will lead to:

• 📶 Frequent switching between 4G and 3G (or 2G sometimes).
• 🐢 Significantly reduce loading speeds, especially during peak hours.
• 🔋 Increased battery consumption due to constant network search.
• 🚫 Unable to connect to the internet in remote areas where Band 20 is the only available band 4G.

In some European countries (e.g. Germany or France), the Band 20 is the main band in the world. 4G-Without the support of the smartphone will not be able to work in local networks at full capacity, so when buying Xiaomi from China or the global version, it is always worth checking whether it is adapted to European standards.

How to check Band 20 support for your Xiaomi

If you're not sure if your smartphone supports the LTE Band 20, there are a few ways to find out, and the most reliable way to do this is to look at the official model specifications on Xiaomi's website or in documents, but often this information is hidden behind technical terms.

1. Check through phone settings: Open Settings → SIM-maps and mobile networks → Name of operator → Network type. If there are any available modes LTE (recommended 4G, This does not guarantee support for the Band 20, but it does indicate the possibility of working with the band. 4G.

Use of the engineering menu:

Type in the phone app the combination ##4636##, then go to Phone Information and see the Set preferred network type section. Here you can see supported ranges, but for accurate analysis, it is better to use specialized applications.

Applications for network analysis:

Install one of the apps, like NetMonster or LTE Discovery, which shows the current bandwidth. If there is a Band 20 (800 MHz) band on the list of available bands, your Xiaomi supports it.

Important: Even if your phone technically supports Band 20, the carrier should provide coverage in this range in your region. To see if the Band 20 is available from your provider, visit its official website or use coverage cards (for example, from OpenSignal or nPerf).

💡

If the engineering menu doesn’t have range information, try entering ##2263##, which will open the Band Selection menu on some Xiaomi models.

Which Xiaomi models support the Band 20?

Not all Xiaomi smartphones support the LTE Band 20, especially models released exclusively for the Chinese market. However, most global and European versions (designated as Global, EEA or EU) are equipped with the necessary modules.

Note that even if the model in the table is marked as supporting Band 20, always check the firmware version and purchase region. For example, the Xiaomi Mi 11 in the China (CN) version does not have this range, whereas the global version (Global) supports. To avoid mistakes when buying, check the marking on the box or in the characteristics on the seller's website.

What if your Xiaomi doesn’t support Band 20?

If your smartphone doesn’t have a module for LTE Band 20, there are a few ways to improve communication quality, although they won’t replace full range support:

• 📡 Use an external antenna or a repeater. 4G-Repeaters or Mi-Fi routers with Band 20 support can amplify the signal and distribute it to your phone over Wi-Fi.
• 🔄 Manually select the operator's network. Sometimes automatic mode connects the phone to less stable ranges. Try manually selecting the operator in the settings: Settings → SIM-map → Choice of network → Manual scanning.
• 📱 Update your firmware. In rare cases, support for new bands is added through software updates. Check for updates in Settings → The phone. → Updating the system.
• 🛒 If stable communication is critical (for work or travel, for example), it may be worth upgrading to a model that supports Band 20.

It’s also worth considering that some carriers (like Tele2) are actively using Band 20 to expand coverage in rural areas, and if you’re out of town often, the lack of this range could make your Xiaomi virtually useless for mobile internet.

💡

If your Xiaomi doesn’t support Band 20, but you live in a city with dense coverage of other bands (like Band 3 or Band 7), the connectivity issues may not be noticeable, but the difference will be obvious when traveling or outdoors.

Band 20 and 5G: What is the connection?

With the transition to 5G, band support is even more urgent, with many carriers using the Band 20 (800 MHz) not only for 4G, but also as the basis for 5G deployments in Dynamic Spectrum Sharing (DSS) mode, where the same frequency is shared between 4G and 5G devices, which means that even if you don’t plan to switch to 5G yet, your Xiaomi’s Band 20 support ensures compatibility with future networks.

For example, in Russia, operators are testing 5G in the n28 band (which includes Band 20), so smartphones with support for this range will be able to connect to 5G without additional modules. If you buy Xiaomi “for growth”, pay attention to models marked 5G and check the specifications for support for n28 or n78 (another popular range for 5G in Europe).

It is important to understand that:

• ⚡ 5G Band 20 is not the same thing. Band 20 can be used as a 4G, for 5G, not all 5G-Phones keep it in mode. 5G.
• 🌍 Regional restrictions: In the US, for example, the Band 20 is not used, so the US versions of smartphones may not support it.
• 🔧 Software limitations: Some Xiaomi may have Band 20 hardware support, but it's disabled at the firmware level (especially in Chinese versions).

Myths and misconceptions about the Band 20 in Xiaomi

There are many myths surrounding the support of mobile bandwidth, especially when it comes to Chinese smartphones.

⚠️ Warning: If a seller claims that "all Xiaomi smartphones support the Band 20," it's not (CN) They don't have this range because they're not used in China. Always check the specifications of a particular version!

Myth 1: “Band 20 is only needed in Europe.”

In fact, this band is widely used in Russia, Ukraine, Belarus and many other CIS countries, for example, in Russia, the Band 20 is used by operators to cover remote areas where other frequencies do not provide a stable signal.

Myth 2: “If a phone supports 4G, it automatically works with the Band 20.”

This is wrong. 4G support means that it's compatible with the technology, but it doesn't guarantee that it's working across all bands. For example, Redmi 9A supports 4G, but it doesn't work with Band 20.

Myth 3: “You can turn on the Band 20 through the engineering menu.”

If the smartphone doesn’t hardware support range, no settings or firmware will add this capability.The engineering menu only allows you to manually select the available ranges from those already supported by the device.

Myth 4: Band 20 is a bad thing for the internet.

Conversely, under weak signal conditions, Band 20 can provide a more stable connection than high-frequency bands (e.g., Band 7 or Band 38), which lose power faster over distance.
