How to check the LTE frequencies on the Xiaomi phone: all ways with explanations

If your Xiaomi smartphone is not catching well 4G-network or switch frequently to 3G, The problem may be the discrepancy between the supported LTE-For example, in Russia, the main operators use Bands 3 (1800 MHz), 7 (2600 MHz) and 20 (800 MHz), and in Europe or Asia, the frequency set may differ dramatically. Knowing the exact ranges of your device will help you avoid buying incompatible devices or set up your network optimally.

In this article, we will discuss all the current methods of verification. LTE-Frequency on Xiaomi, Redmi and POCO — From standard settings to hidden engineering menus, you'll learn how to identify supported root-free ranges, which apps provide the most accurate information, and what to do if the phone doesn't see the right frequency. We will also focus on the nuances for models with MediaTek and Qualcomm Snapdragon, since they have different approaches to diagnosis.

Why it's important to know LTE-Frequency of Xiaomi

Many users have a situation where the smartphone worked perfectly with 4G in one region, but after moving or changing the operator, the Internet speed dropped sharply, the reason often lies in the incompatibility of frequency bands.

• 📡 MTS in Moscow is actively using Band 7 (2600 MHz), and your Redmi Note 10 does not support it - instead of using it. 4G You get slow. 3G.
• 🌍 When buying Xiaomi from China, there is a risk that it will not work with European frequencies (for example, there is no Band 20, critical for coverage in rural areas).
• 🔄 Even within the same model, there may be regional versions with different ranges (e.g., different ranges, POCO X3 Pro for India and Global Version).

Knowing the exact frequencies will help:

• 🛒 Choose the right model when buying (especially if you take a smartphone from abroad).
• 📶 Optimize network settings for maximum speed.
• 🔧 Diagnose connection problems (for example, why the phone is not catching) 4G place-by-place).

⚠️ Note: Some operators (e.g, Tele2 In Russia, they use rare bands like Band 38 (TDD 2600 MHz) If your Xiaomi doesn’t support this frequency, internet speeds will be limited even if there is a signal. 4G.

Method 1: Checking through standard Android settings

The easiest method is to look at network information in the standard menu.It works on all Xiaomi smartphones with MIUI 12 and later, but only shows the current range used, not all supported.

Instructions:

1. Open the Settings. → SIM-maps and mobile networks.
2. Choose an active one SIM-map.
3. Tap on the network type (or preferred network type).
4. If available, select LTE Only (to avoid switching to 3G/2G).
5. Go back and open Network Information (or Status) SIM-map).
6. Find the Network Type bar, where the current range can be displayed (e.g. LTE Band 3).

Limitations of the method:

• 📵 It only shows active range, not all supported ranges.
• 🔄 Some firmware may not have network information.
• 📱 Does not work on models with MediaTek Helio (e.g. Redmi) 9A).

💡

If the settings don’t have range information, try turning on the plane mode for 10 seconds, then turn off and check again – sometimes this helps update network data.

Method 2: Engineering menu (for MediaTek processors)

Xiaomi smartphones on MediaTek chips (for example, Redmi) 9/9A/9C, POCO M3) Allows you to know all the supported LTE-This method doesn't require root rights, but you have to type in manual commands.

Step-by-step:

1. Open the Phone app and type in the combination: ##4636## Some models may work: ##36446337###
2. Select Phone Information (or Phone Information).
3. Scroll down to the Set preferred network type block.
4. Click on the drop-down menu and select LTE only.
5. Go back and find the LTE Band string, which will list all supported bands (e.g. B1/B3/B5/B7/B8/B20).

Display example for Redmi 9C (MT6765G):

LTE Band: B1/B3/B5/B7/B8/B20/B28/B38/B40/B41

⚠️ Attention: On some firmware MIUI The engineering menu can be blocked. If nothing happens after you enter the code, try using apps like this. MTK Engineering Mode from Google Play.

Charge your phone at least 50%|Connect to Wi-Fi (in case of resetting settings)|Write down the current network settings (screenshot)|Do not change the parameters unless you are sure of their value.-->

Method 3: Engineering menu (for Qualcomm Snapdragon processors)

Devices on Qualcomm Snapdragon (e.g. Xiaomi) 11T, POCO F3, Redmi Note 10 Pro has a different engineering menu. QC Diagnostic Mode.

Instructions:

1. Enter in the phone app: ##4636## or alternative code: #0#
2. Go to the phone information section.
3. Find the Set preferred network type and select LTE only.
4. Scroll down to the LTE Band block, where all supported bands will be listed.

If the code doesn’t work, try an alternative method:

• Install the Shortcut Master app from Google Play.
• In the search, enter the Engineering Mode.
• Open the hidden menu and go to Telephony → Band Mode.

Example of output for POCO F3 (Snapdragon 870):

Supported LTE Bands: 1, 2, 3, 4, 5, 7, 8, 12, 17, 20, 28, 32, 38, 40, 41

Method 4: Applications for verification LTE-frequency

If standard methods don't work, third-party utilities will come to the rescue, not only showing the ranges supported, but also visualizing information about the current connection.

Top.-3 apps:

How to use NetMonster:

1. Install the app and give access to phone functions.
2. Go to the LTE tab.
3. The Band block will be listed: 📶 Current range (e.g. Band 3). 📋 All supported (in the Device info section) → Supported bands).

⚠️ Note: Some Xiaomi models may not show all ranges due to manufacturer restrictions. For accurate information, check the official specifications (see method 5).

Method 5: Official Specifications on Xiaomi

If you want 100% accurate information about supported ranges, the best source is the official Xiaomi website.This is especially important when buying a phone from another region.

How to find the data:

1. Go to the official Xiaomi website.
2. In the search, type in your phone model (e.g. Redmi Note 12 Pro+ 5G).
3. Open the device page and go to the Specifications (or Specifications) tab.
4. Find the Network & Connectivity section → LTE bands.

💡

Official data is the only reliable source for checking carrier compatibility, and the application side may show incomplete information due to MIUI limitations.

Method 6: Checking through ADB (for advanced users)

If none of the previous methods worked, you can use ADB (Android Debug Bridge) to get detailed information about the communication module, which requires a computer and basic command line skills.

Instructions:

1. Install ADB and Fastboot Tools on PC.
2. Turn on USB Debugging on your phone: Go to Settings → About Phone. Tap 7 times on MIUI to activate Developer Mode. Return to Settings → Additional → For Developers and enable USB Debugging.

adb shell


getprop gsm.lte.bands

Or for more detailed information:

adb shell


service call telephony 20 | cut -c 52- | xxd -r -p | grep -o '[0-9]*'

Example of conclusion:

gsm.lte.bands: 1,3,5,7,8,20,28,38,40,41

Limitations of the method:

• 🖥️ Requires a computer and installation ADB.
• 🔧 On some firmware MIUI The team may not work because of limitations.
• 📵 Not all models support information output via getprop.

💡

If getprop gsm.lte.bands doesn’t work, try adb shell dumpsys telephony.registry – sometimes there’s information about supported ranges.

What to do if the phone does not support the right LTE-frequency

If it turns out that your Xiaomi doesn’t support your carrier’s ranges, there are a few ways to fix the problem:

• 🔄 For example, if you don’t have a Band 20 but you have a Band 3, choose a carrier that actively uses 1800 MHz (for example, Beeline in Russia).
• 📶 Turn on roaming (if the operator supports firewalling), sometimes this allows you to connect to the frequencies of partner networks.
• 🔧 Update the firmware. MIUI sometimes adds support for additional ranges (especially relevant for models with MediaTek).
• 📱 Buy the outside. 4G-modem with support for the desired frequencies and use the phone in access point mode.

If the problem is hardware incompatibility (for example, a phone from China does not support European frequencies), the only radical way is to replace the radio module, but it is expensive and requires professional repair.

⚠️ Warning: Some gray vendors claim that you can flash support for new frequencies through modified software. It's a myth that the hardware limitations of a radio module cannot be circumvented software. The most you can do is activate hidden ranges if they are physically present in the chip but disabled by the firmware.
