What Is VoLTE and How to Enable It on Xiaomi Phones (Step-by-Step Guide)

 

🔹 What Is VoLTE?

VoLTE (Voice over LTE) is a communication technology that routes voice calls through your 4G or LTE data network, instead of the old-fashioned 2G/3G voice channels.
When VoLTE is active on your Xiaomi, Redmi, or POCO device, your voice is digitized and sent as data packets. This leads to clearer calls, faster connections, and better overall performance.

🔹 How Does VoLTE Work?

Traditional mobile calls use circuit-switched networks that max out around 8 Kbps, but VoLTE compresses and transmits voice data at up to 13 Kbps.
That means:

  • Sharper, high-definition sound

  • Near-instant call setup

  • Stable voice quality, even in low-signal areas

Unlike VoIP services such as WhatsApp or Skype, VoLTE doesn’t rely on third-party apps and uses less battery power because it’s built directly into the phone’s network system.

Also, since VoLTE uses LTE or Wi-Fi connections, you can talk and browse the web at the same time — something older GSM calls can’t do.

🔹 How to Enable VoLTE on Xiaomi, Redmi, and POCO Phones

By default, most Xiaomi devices have VoLTE turned off.
Follow these exact steps to activate it:

Step 1: Unlock the Hidden VoLTE Menu

  1. Open the Phone (Dialer) app.

  2. Dial this code exactly as shown:

    *#*#86583#*#*

  3. You’ll see a message pop up on screen:
    “VoLTE carrier check was disabled.”
    This confirms that the hidden VoLTE feature is now unlocked.

Step 2: Enable VoLTE from Settings

  1. Open Settings on your device.

  2. Tap SIM cards & mobile networks.

  3. Select your SIM card (for dual-SIM devices, choose SIM 1 or SIM 2).

  4. Scroll down and turn on Use VoLTE.

    → Menu path summary:
    Settings › SIM cards & mobile networks › [Your SIM] › Use VoLTE

Step 3: Confirm That VoLTE Is Active

  • After enabling, you should see a VoLTE icon appear in the status bar next to your signal bars.

  • Make a test call — the quality should be noticeably clearer.

If you don’t see the icon, check whether your mobile carrier supports VoLTE for your plan and region.

🔹 Key Benefits of VoLTE on Xiaomi Devices

✅ HD Voice Quality: Calls sound more natural and lifelike.
✅ Instant Call Setup: No more waiting for the call to connect.
✅ Use Data During Calls: Continue browsing, streaming, or using GPS.
✅ Better Battery Life: Consumes less power than app-based calls.
✅ Supports Wi-Fi Calling: Extends coverage indoors or in low-signal areas.

🔹 Troubleshooting Tip

If the Use VoLTE option doesn’t appear under SIM settings:

  1. Make sure your device runs the latest MIUI version (Settings › About phone › MIUI version › Check for updates).

  2. Contact your carrier to confirm VoLTE is available for your SIM.

  3. Reboot your device and repeat the activation steps.

🔹 Conclusion

Activating VoLTE on your Xiaomi, Redmi, or POCO smartphone gives you HD-level call quality, instant connections, and improved efficiency.
With just a few simple settings, you’ll transform your phone calls into a modern, high-definition experience — powered by 4G and LTE.
