How to Know What Frequencies Your Xiaomi Phone Supports: 5 Ways to Work

You bought Xiaomi and you want to see if it's going to work with your carrier at top speed, or you're planning a trip abroad and you're wondering if your smartphone is going to work for local networks, and the bands that you support are the key parameter that determines your device's compatibility with mobile networks, but how do you know if the store's specifications are only about abstract "4G" or "5G"?

In this article, we’ll look at all the ways to check bands on Xiaomi, Redmi and POCO smartphones, from standard settings to hidden engineering menus, how to decrypt technical specifications, where to find official manufacturer data, and why sometimes even the same models support different frequencies, and we’ll also explain why some bands can be blocked by firmware even with hardware support.

1.What are bands and why is it important

Band refers to a specific frequency range that mobile operators use to transmit a signal, such as B1 (2100 MHz) or B7 (2600 MHz), each operator in each country runs on its own set of bands — and if your phone does not support them, you either won’t catch the network or will work at a reduced speed.

That's why it's critical:

• 🌍 Roaming abroad: Bands are used in the US and Japan B2/B4/B12/B66, The most common ones are missing from Xiaomi’s “global” versions for Europe.
• 🚀 Speed. 5G: Even if the phone supports 5G, He may not be working with you. n78 (3500 MHz – the main range for Russian operators.
• 📶 Low signal areas: Some bands (e.g, B20 (800 MHz)) are better at penetrating buildings and their absence will make communications unstable.

For example, Xiaomi 13 Pro for China (M2210132C) does not support European B20 and B28 bands, while the global version (2304FPN6DG) includes them. and POCO X5 Pro 5G in the Indian version lacks support for n78, which is critical for 5G in Russia.

⚠️ Warning: Manufacturers often release a single model with different sets of bands for different markets, even if the box says "5G", It does not guarantee the support of everyone. 5G-ranges of your operator.

2. Method 1: Checking through phone settings (without applications)

The easiest method is to view the network information directly from the Xiaomi menu, which is suitable for most models on MIUI 12-14 and does not require additional software installation.

Instructions:

1. Open the Settings. → SIM-maps and mobile networks.
2. Choose yours. SIM-card (if there are several).
3. Go to Network Type or Network Settings.
4. Click on Additional Settings (in some firmwares, this item may be called Network Mode).
5. Scroll down to the Network Information or Network Status block.

Here you will see the current communication standard (e.g. LTE or NR (5G)) and the band number to which the phone is connected (e.g. B3 or n78), but this method only shows the active band, not the full list of supported ones.

-->

On some models (for example, Xiaomi 12T or Redmi Note 11 Pro+) the path may be different:

Settings → Memory and SIM- Cards → [Select SIM] → Network Type → Advanced Settings

⚠️ Note: On phones with custom firmware (like LineageOS), this method may not work, Tele2 In Russia, they hide detailed information about bands.

Method 2: Engineering menu (hidden codes)

For advanced users, there is a way to get a full list of supported bands through an engineering menu, a method that works on most Xiaomi, but requires caution - wrong actions can disrupt the network.

Steps:

1. Open the Phone app and type in the combination: ##4636## On some models (e.g. POCO F4) may work: #36446337###
2. Select Phone Information (or Phone Information).
3. Scroll down to the Set preferred network type or Network Type block.
4. Click on Band Mode or Preferred Network Band – here you will see a list of all supported bands for 2G/3G/4G/5G.

Example of output for Xiaomi 11T Pro:

If the code doesn’t work, try alternatives:

• 📱 For Redmi. 9/10: ##4636## → Information on SIM-map.
• 📱 For POCO X3/X4: ##36446337## → RF Band Selection.
• 📱 For older models (Redmi) 4X, Mi A1): ##4636## → Service Mode.

Method 3: Applications for Network Analysis

If standard methods fail, third-party apps will come to the rescue, not only showing the supported bands, but also analyzing signal quality, speed, and even offering optimal settings.

Top.-3 apps:

• 📊 NetMonster (free, no ads) - shows the current band, signal level and neighboring towers. 5G.
• 🔍 Network Cell Info Lite — displays all available bands, operators and frequencies.
• 🛠️ MTK Engineering Mode (MediaTek only) – gives access to low-level modem settings.

How to use NetMonster:

1. Install the app from Google Play.
2. Run it and wait for the network to be determined (it can take up to 30 seconds).
3. Go to the SERVING CELL tab – there will be a current band (e.g. LTE B3).
4. For a full list of supported bands, click on the icon ⚙️ → Device Info → Supported Bands.

Example of output for the Redmi Note 12 Pro+:

Supported LTE bands: 1, 3, 5, 7, 8, 20, 28, 38, 40, 41




Supported 5G bands: n1, n3, n5, n7, n8, n28, n41, n77, n78

Important: Some apps require root rights to show a full list of bands, and without them, they will only display the ranges that are currently available in your location.

5. Method 4: Official Xiaomi Specifications

If you want accurate data from the manufacturer, rather than the current state of the phone, consult official sources, which is especially useful when buying a new device or checking compatibility with foreign carriers.

Where to look:

• 🌐 Xiaomi official website: Go to the model page (e.g. Redmi Note 12 Pro)+) Find the Network & Connectivity section.
• 📄 Documentation for 4PDA: On the forum 4PDA In the theme of your model there is usually a table of bands with notes for different regions.
• 📦 Box or booklet: Some models (e.g. Xiaomi 13 Ultra) have bands on the back of the package.

Example of official specifications for Xiaomi 13 Lite:

Note the model code (e.g. 23013PC75G for Xiaomi 13) which is usually listed on the battery sticker or in the settings (Settings → About Phone → Model).

• G is the global version (Europe, Latin America).
• C - China.
• I is India.
• R - Russia (sometimes found in Redmi).

⚠️ Note: Xiaomi sometimes lists the maximum possible set of bands for the model, but in reality it may differ depending on the firmware, POCO F5 specifications support n79, But in Russian firmware, this band is disabled.

Method 5: Verification through IMEI

If you don’t have access to your phone (for example, you’re just planning to buy), you can find out supported bands by IMEI. This method works for most Xiaomi models released after 2018.

Instructions:

1. Find out the phone's IMEI: On the device: Settings → Phone → General information → IMEI. On the box: usually indicated on the sticker. Through the code: *#06# (dial in the Phone app).

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

Advantages of the method:

• ✅ It works even if the phone is turned off or not yet purchased.
• ✅ Shows the actual configuration for a particular device (not the general specifications).

Disadvantages:

• ❌ Some websites show outdated data.
• ❌ For new models (e.g. Xiaomi 14) information may not be available.

💡

If an IMEI site doesn't find your model, try manually typing its name into FrequencyCheck, a service that specializes in band compatibility with operators around the world.

7. Frequent problems and solutions

Even if your Xiaomi supports the right bands, you may run into problems, and here are the most common cases and ways to solve them:

Problem 1: Phone doesn't catch 5G, though band supported

• 🔄 Check the settings: Settings → SIM-map → [Yours. SIM] → Type of network → 5G.
• 📱 Update the firmware: some bands are activated only after updating the modem.
• 🔧 Reset network settings: Settings → Memory and SIM-map → Resetting network settings.

Problem 2: Roaming doesn’t have a network, although bands match

• 🌍 Make sure roaming is enabled: Settings → SIM-map → Data roaming.
• 📡 Check if the band is blocked by the operator (for example, AT&T in the US blocks some ranges for uncertified devices).
• 🔄 Reboot your phone on the plane: Turn on Flight Mode for 30 seconds, then turn off.

Problem 3: Apps show bands, but speed is low

• 📶 Check the load of the tower: use NetMonster to analyze the neighbors of the networks.
• 🔄 Switch to another band manually (required) MTK Engineering Mode or Qualcomm EngineerMode).
• 📱 Drop it. APN: Settings → SIM-map → Access points (APN) → Reset to factory.

💡

If you bought your phone in China, there's a good chance that bands in your region are locked at the firmware level, and that's where the only thing that helps is flashing it to the global version of MIUI.
