How to check the supported band frequencies on your Xiaomi phone: 5 working methods

Buying a Xiaomi smartphone abroad or choosing a model for a particular operator often raises the question: what band band does the device support? 4G/5G For example, a phone bought in China may not be able to catch Russian Band frequencies. 20 (800 MHz), which is actively used by local operators.

In this article, we will analyze all the current ways to check supported band on Xiaomi, Redmi and smartphones. POCO — From standard settings to hidden engineering menus, you'll learn how to define root-right-free ranges, which apps give you the most accurate information, and what to do if your phone doesn't see the right frequencies, and how to distinguish hardware from software constraints and whether you can bypass them.

If you are planning to travel or change operators, this information will help avoid connection problems. For example, in Europe, Band 3 (1800 MHz) is actively used, and in the United States – Band 4 (AWS). Without support for these ranges, the smartphone will only work in mode. 2G Or it will be completely without a network.

1.What is a band and why is it important for Xiaomi

Band refers to a specific frequency range that cellular operators use to transmit data, each band having a different number (e.g. Band 1, Band 7) and operating frequency (e.g. 2100 MHz or 2600 MHz).

• 📶 Communication quality: If the operator is broadcasting at a frequency that your phone does not support, the signal will be weak or absent.
• 🚀 Internet speed: Band 3, Band 7 and Band 20 bands in Russia provide high speed 4G, Band 1 is often overloaded.
• 🌍 Roaming: operators can use other frequencies abroad, for example, Band 1 and Band 3 are popular in Thailand, and Band 2, Band 4 and Band 12 are popular in the United States.

Xiaomi smartphones are often released in several versions:

• 🇨🇳 Chinese version (China) ROM): It may not support European/Russian frequencies (e.g., Band 20 is not available).
• 🇪🇺 Global version (Global) ROM): It is adapted to international standards, but sometimes lacks some Chinese bands (e.g. Band). 38/39/40/41 for TD-LTE).
• 🇮🇳 Indian version: optimized for local operators (e.g. Band 40 for Jio).

The problem is complicated by the fact that even within the same model (for example, Xiaomi 13 Pro) there can be different modifications of the chipset (for example, Snapdragon 8 Gen 2 for the global market and Dimensity 9200).+ for China), which support different frequency sets.

⚠️ Note: If you buy Xiaomi from hand or on foreign sites (such as AliExpress), always check the model version.+ 5G For China and the global version have different band sets – this can make the phone useless in your region.

2. Method 1: Check band through phone settings (no apps)

The easiest method is to look up the frequencies in Xiaomi’s standard settings, which doesn’t require additional programs to be installed, but only gives limited data.

Instructions:

1. Open the Settings app (cog icon).
2. Go to the About Phone section (or About the device on the phone) MIUI 14+).
3. Put on the item All characteristics (or specifications).
4. Scroll down to the Network or Wireless Networks block.

Here you will see a list of supported communication standards (e.g, 2G: GSM 850/900/1800/1900), But there may not be a complete list of bands, POCO F5 Xiaomi 12T) Only the main ranges are displayed, without detailing by band numbers.

To get more accurate information, you can use the code for the engineering menu:

##4636##

Once you enter this code, the Test menu will open, where you select Phone Information. Network Type or Network Information can display the current frequencies you use, but not all of the frequencies you support.

⚠️ Attention: On some firmware MIUI (In this case, the code will not work, and you will need an alternative method.

Clarify the model version (Global/China/India)|View the list of supported standards in "About the phone"|Check the work of the engineering menu (##4636##)|Compare the data with the official specifications on the Xiaomi website-->

Method 2: Use of applications for frequency analysis

If standard settings don't give you the full picture, specialized applications come to the rescue, not only showing the ranges supported, but also analyzing the current network connection.

Top.-3 Apps to check band on Xiaomi:

How to use NetMonster (Step-by-step):

1. At the top of the screen will be a list of all the bands your phone supports, and below is the current range used.

Example of display in NetMonster for Xiaomi 13 Ultra:

If your carrier’s range is not included in the list of supported bands (for example, Band 20 for MTS in Russia), this means that the phone will not be able to connect to this frequency even with a perfect signal.

💡

If the application does not show 5G-ranges, upgrade the firmware of the phone. on some Xiaomi models support 5G activate only after the latest version is installed MIUI.

Method 3: Engineering menu (MTK qualcomm)

For advanced users, there is an engineering menu check that gives access to low-level modem settings, which works on most Xiaomi smartphones, but requires caution that wrong actions can disrupt the network.

For phones on Qualcomm chipsets (Snapdragon):

1. Enter the code ##4636##
2. Select Phone Information.
3. Scroll down to the Network Type block – supported bands can be displayed here.

For phones on chipsets MediaTek (Dimensity, Helio):

1. Enter the code ##36446337## (or #3644633## on some models).
2. Go to the Connectivity section → Band Selection.
3. Here will be a complete list of supported ranges for 2G/3G/4G/5G.

Example of display for POCO X5 Pro 5G (Snapdragon 778G):

LTE Bands: 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 20, 26, 28, 32, 38, 40, 41, 42, 48, 66




5G Bands: n1, n2, n3, n5, n7, n8, n12, n20, n28, n38, n40, n41, n66, n77, n78

⚠️ Attention: On some firmware MIUI The engineering menu can be disabled. If the codes don't work, try installing the app. MTK Engineering Mode (for MediaTek) or Qualcomm Mode Changer (for Snapdragon) from Google Play. But remember: changing the settings in these menus can lead to loss of network!

Method 4: Testing by IMEI phone models

If you don’t have a phone on your hands (for example, you’re planning to buy one), you can find out the frequencies you support by using it. IMEI This method is suitable for testing before buying on AliExpress, Amazon or handheld.

Step 1. Find it. IMEI phone

• 📦 On the device box (usually on a barcode sticker).
• 📱 In settings: About the phone → Background → IMEI.
• 🔢 Through code: *#06#

Step 2. Check the specifications for IMEI

Enter. IMEI on-site:

• 🔗 IMEI.info – shows the model, year of release and main characteristics.
• 🔗 Kimovil - detailed specifications, including supported bands.
• 🔗 GSMArena – a database of smartphones with filters by region.

Example of the report for Xiaomi Redmi Note 12 Pro+ 5G (global):

Note that even if the model supports the desired band, the firmware can block its use. For example, Chinese versions of Xiaomi often do not activate the Band 20 in Russia, even if it is supported hardware.

💡

Before buying Xiaomi abroad, always check the bands you support for your region. Even if the phone is physically capable of operating at the right frequency, the firmware can artificially restrict its use.

Method 5: Analysis of the current network connection

If you want to know what frequency your Xiaomi is currently running, you can use a combination of standard tools and applications to help you understand why the Internet speed is low or the signal is unstable.

Method 1: Through Android Settings (without apps)

1. Open the Settings. → SIM-maps and mobile networks.
2. Choose yours. SIM-map.
3. Tap by Network Type (or Preferred Network Type).
4. If the mode is available only LTE or 5G, The phone is connected to the corresponding network.

Method 2: Network Signal Guru

This app shows the band you're actually using, not just the bands you're supporting. Download it from Google Play and follow the instructions:

1. Launch the application and provide access to network data.
2. Go to the tab. LTE or 5G.
3. The Serving Cell block will include the current Band, PCI, RSRP (signal-level).

Example of a report for Xiaomi 12T Pro on the MegaFon network:

Network: LTE (4G)




Band: 7 (2600 MHz)




PCI: 123




RSRP: -95 dBm (good signal)




Speed: 78 Mbps

If you see that the phone is connected to Band 3, but the speed is low, it may be overloaded, in which case you can manually select a different range (if supported).

1. Is it activated? 5G customized SIM-map.

2. whether your tariff supports 5G (check with the operator).

3. whether the firmware has been updated to the latest version (in older versions) MIUI 5G Could have been turned off software).-->
