How to check Band LTE on Xiaomi smartphone: 7 working ways

If your Xiaomi is not good at catching 4G-network or you are planning to travel abroad, knowledge of supported LTE-Band will help avoid problems with mobile Internet. the manufacturer rarely indicates this information in the characteristics of the device, but it can be found independently - either through standard settings, or using hidden menus or specialized applications.

Many users make a mistake of focusing only on the model name (e.g. Redmi Note 12 Pro+ or POCO X5 Pro). In fact, even within the same line, versions with different communication modules (e.g. for China, Europe or India) can occur, which directly affects the frequencies supported. In this article, we will analyze all the current methods of checking Band LTE - from simple to advanced, including analysis of technical specifications and working with engineering menus.

It is especially important to know the ranges if you:

  • 🌍 You are traveling and want to buy a local SIM-map 4G.
  • 📶 They have a bad signal in their area.
  • 🔄 Planning to buy a used Xiaomi smartphone with an unknown version.
  • 🛠️ Suspected hardware malfunction of the communication module.

1. Verify through Android settings (the easiest way)

On most Xiaomi smartphones (including Redmi, POCO, and Mi), the bands you support can be found in the standard menu, which does not require root or third-party app rights, but does not work on all firmware.

Instructions:

  1. Open the Settings. → The phone.
  2. Tap the MIUI version several times until the notification “You’ve become a developer!” appears (if you haven’t activated this mode already).
  3. Return to the main settings menu and select Additional → For developers.
  4. Scroll down to the Network block and find the item Modem Information or Information about SIM-map.
  5. In the window that opens, look for lines like LTE Band, Supported Bands, or 4G Frequencies.

Check out the MIUI version (update to the latest version)

Reboot the phone.

⚠️ Note: Some firmware (especially global ones) may not have this item or display incomplete data. e.g., Redmi Note 11 Pro+ s MIUI The 14 often shows only the main ranges, without support for the Band 28 (700 MHz), which is important for Europe.

2.Use of the engineering menu (#4636##)

The hidden engineering menu is a universal tool for network diagnostics, available on all Xiaomi smartphones, but the interface may vary depending on the firmware version.

How to open it:

  1. Launch the Phone app.
  2. Enter the combination: ##4636## (without pressing the call button).
  3. In the menu that opens, select Phone Information (or Phone Information).
  4. Scroll down to the Set preferred network type block and look at the LTE Band bar.

You can also force specific ranges to be enabled in this menu (for example, for testing), but it is not recommended to change settings unnecessarily - this can lead to network loss.

What to do if the engineering menu is not opened?
On some firmware (e.g. MIUI for China), access to the engineering menu is blocked. In this case: 1. Try entering the combination through Google's Phone app (install it from the Play Market if removed). 2. Use alternative codes: - ##225## to check the basic information about the module. - ##7378423### - Service menu (does not work on all models). 3. If nothing helps, go to methods using third-party applications.

3. Network analysis applications: NetMonster, LTE Discovery

If standard methods don't work, specialized utilities will come to the rescue, not only showing the ranges supported, but also analyzing the current network connection.

Top.-3 applications:

  • 📡 NetMonster displays all available frequencies, signal strength and cell information. Supports data export to file.
  • 🔍 LTE Discovery shows the current Band, signal strength and connection history.
  • 📊 Network Cell Info Lite – visualizes network data on the map, useful for comparing coverage of different operators.

An example of working with NetMonster:

  1. Install an app from the Play Market.
  2. Run it and wait for the network scan.
  3. Go to the Bands tab – all supported bands (including GSM, WCDMA, and LTE) will be displayed here.
  4. For detailed information, tap on any Band - a window with frequency, channel width and other parameters will open.

⚠️ Attention: Some applications (e.g, MTK Engineering Mode requires root rights to fully access data, and without them, they can show incomplete information, especially on smartphones with MediaTek processors (e.g. Redmi). 10C or POCO M5).

Analysis of the technical specifications by model

If you don’t have access to the phone itself (for example, choosing a model to buy), you can find out the supported ranges from official data.

Where to look:

  1. Xiaomi official website: On the model page (e.g. Redmi Note 13 Pro+) in the Specifications → Network & Connectivity section.
  2. GSMArena database: Type the model into search and go to the Network tab. Here are all supported Bands for each version (e.g. Global, China, India).

Example of Band support difference for POCO X5 Pro 5G:

Device versionSupported LTE BandNote
Global (2210136PG)1, 2, 3, 4, 5, 7, 8, 20, 28, 38, 40, 41Suitable for Europe and Asia
China (2210136PC)1, 3, 5, 8, 38, 40, 41There are no Band 20 (800 MHz) and Band 28 (700 MHz)
India (2210136PI)1, 3, 5, 8, 40, 41Minimum range set

💡

Even if the model looks the same, versions for different regions can support different versions. LTE-Always specify the device code (e.g., ranges, 2210136PG global version POCO X5 Pro).

5. Check through ADB (for advanced users)

If you're familiar with ADB (Android Debug Bridge), you can get full information about the communication module, including hidden ranges, which is suitable for fault diagnosis or deep analysis.

Instructions:

  1. Install Platform Tools on your PC.
  2. Activate Debugging by USB in the developer settings on your phone.
  3. Connect your smartphone to your computer and execute the command in the terminal:
adb shell


su




getprop gsm.lte.bands

If root rights are not available, try an alternative command:

adb shell dumpsys telephony.registry

In the conclusion, look for lines like:

mLteBandList=[1, 3, 5, 7, 8, 20, 28, 38, 40, 41]

💡

If the command doesn't work, try using QPST (for Qualcomm) or MTK Droid Tools (for MediaTek), which require additional customization but provide the most complete data about the communication module.

6. Determination of Band by Current Connection

If you want to know which Band is currently in use (for example, to compare it to an operator’s coverage), do the following:

Ways:

  • 📱 Using the engineering menu: in ##4636## in the tab Phone Information, see the line LTE Band in the Serving Cell Info block.
  • 🌐 Through the operator’s website: some providers (e.g. Megafon or Beeline) show the current frequency in their personal account.
  • 📊 Through CellMapper: It not only defines the Band, but also builds a coverage map with towers on it.

Example: If you see Band 3 (1800 MHz) but know your phone supports Band 20 (800 MHz), it may mean the carrier is not providing access to a more stable frequency in your region.

How to forcefully switch to another band?
⚠️ This is a risky operation that could lead to network loss! If you are confident in your actions: 1. From the engineering menu (#4636##) select Set preferred network type. → LTE Manually select the Band you want (if the menu supports this feature). 3. Restart the phone. If the signal goes missing, return the settings to the factory settings (Auto).

7. Verification through service centers and communication operators

If independent methods did not give a result or you suspect a hardware malfunction, you can seek help from specialists.

Where to go:

  • 🏠 Xiaomi Service Center: Provide a full diagnostics of the communication module (free if the device is guaranteed).
  • 📡 Communications operator: Some salons (for example, MTS or Tele2) They can check the compatibility of your phone with their network. IMEI.
  • 🔧 Independent workshops: Use professional equipment (e.g., professional equipment, RIFF Box) for in-depth analysis of the module.

What to tell a specialist:

"I need to know which ones LTE-My Xiaomi [model] is probably the problem, because the phone is not catching the Band 20 (800 MHz), which is used by my carrier in this region?"

Frequent Mistakes and How to Avoid Them

When checking Band LTE, users often face typical problems. Here's how to solve them:

  • 🔄 "There is no information on the Band in the engineering menu" → Update your firmware or use third-party apps (NetMonster).
  • 📵 "Phone's not catching. 4G, though the band is supported" → Check the settings. APN or reset the network (Settings) → SIM-map → Resetting network settings).
  • 🌐 "GSMArena lists some Bands and the phone shows others" → Check the version of the device (e.g. Global vs China).
  • 🔋 "After changing the band, the phone discharges faster" → Some bands (like Band 41) consume more power.

💡

If your Xiaomi doesn’t support the right Band, but you travel frequently, consider buying an external band. 4G-Modem (e.g. Xiaomi MiFi) with the right frequencies.

My Xiaomi doesn't roam 4G. Is it because of Band?
Most likely, yes. Many carriers abroad (such as Thailand or the UAE) use Band 3 (1800 MHz) or Band 8 (900 MHz), which are supported by most smartphones. But if your phone is released for China (CN version), it may not have the Band 20 (800 MHz) that is common in Europe. Check compatibility through the LTE Discovery app or on the carrier's website.
How do I know which version of Xiaomi I have, Global, China or another?
There are several ways: Look at the box or in the documents — usually the version (eg, Global Version). In the settings: Settings → About phone → MIUI. If at the end there are letters CN — Chinese firmware, EU — European, IN — Indian. Through IMEI: the first 8 digits (model TAACR) you can check on the website IMEI.info.
Can I add support for the new band through the firmware?
No, support. LTE-The bands are defined by the hardware (communication module), and no firmware can add missing frequencies. However, in rare cases custom firmware (for example, LineageOS) can unlock hidden bands if they are physically present in the module, but disabled by the manufacturer. Risks: loss of warranty, unstable network operation.
Why is it that the engineering menu does not display all the Bands that are specified in the specifications?
This is normal. The engineering menu often shows only the active ranges that the phone can use in the current region (based on the data). SIM-The full list of supported Bands can only be seen through the ADB or in technical documentation.
Which band is the most important for Russia?
In Russia, operators use the following main bands: Band 3 (1800 MHz) - the most common, used by all operators. Band 7 (2600 MHz) - high speed, but low penetration into buildings. Band 20 (800 MHz) - the best coverage in rural areas (using MTS and Tele2), Band 38/40/41 (TDD-LTE) - for high-speed Internet in cities. If your phone does not support Band 20, in the outback you may have problems with the signal.
