How to enable only 4G on Xiaomi Poco X3 Pro: all ways

Why do Poco X3 Pro users want to keep 4G?

The Xiaomi Poco X3 Pro is one of the most popular mid-range smartphones, but its owners often face the problem of unstable Internet connections, the reason being automatic switching between 2G/3G/4G networks, which does not always work optimally, in densely populated areas or on the outskirts of cities, the phone can “clung” to a weak 3G signal, instead of holding a stable 4G – even if a dedicated band is available.

Enabling LTE-only mode solves several key problems:

  • 📶 Higher download speeds – no switching to slow networks.
  • 🔋 Battery savings – the phone doesn’t waste energy on the constant search for alternative networks.
  • 🎮 Stable ping – critical for online gaming and video calls.
  • 📱 Less "hanging" during data transfer (for example, in messengers or social networks).

However, in standard MIUI settings, the option of forced 4G only is often hidden. In this article, we will discuss all working ways to activate the “LTE Only” mode on the Poco X3 Pro, including hidden engineering menus and alternative methods for different versions of the firmware.

📊 You've already tried to include only 4G on the Xiaomi?
Yeah, through the settings.
Yeah, through the engineering menu.
No, it didn't work.
I haven't tried it, but I want to.

Method 1: Standard MIUI settings (if available)

On some versions of MIUI (especially global or European ones), the choice of network type can be seen without further manipulation.

  1. Open Settings → SIM cards and mobile networks.
  2. Choose yours. SIM-card (if two of them).
  3. Tap on the network type (or preferred network type).
  4. Look for options on the list: 🔹 Only 4G (LTE) — perfect. 🔹 4G/3G/2G (Auto: Standard mode (not suitable). 🔹 Only 3G or 2G — don't choose.

If you don't have 4G Only on the list, move on to the next option, which is often not available on India ROM or Chinese MIUI.

💡

Before changing the type of network, check the balance of mobile Internet – some operators (such as Tele2) can write off traffic when switching between generations of networks.

Method 2: Engineering Menu (MTK Engineer Mode)

Xiaomi Poco X3 Pro is built on the Qualcomm Snapdragon 860 platform, but to access hidden network settings, we will need an engineering menu.

  1. Open the Phone app and type the combination: ##4636## Some firmware may run an alternative code: ##36446337###
  2. You will be taken to the Testing menu. Select Phone Information (or Phone Information).
  3. Scroll down to the Set preferred network type block.
  4. In the drop-down list, select LTE only (or 4G only).
  5. Press OK and restart the phone.
