Voice over LTE (VoLTE) is a modern telecommunication technology that transforms traditional voice calls into digital data packets transmitted over LTE networks. Unlike standard 2G or 3G calls that rely on analog voice channels, VoLTE delivers HD-quality voice, faster connections, and improved network efficiency.
For Xiaomi users — whether you own a Redmi Note 8 Pro, Xiaomi Mi A2, or any other Xiaomi, Redmi, or POCO device — enabling VoLTE enhances your calling experience while maintaining reliable internet connectivity.
This guide explains what VoLTE is, how it works on Xiaomi devices, how to activate it, and the benefits you’ll notice immediately after enabling it.
VoLTE stands for Voice over Long-Term Evolution. In simple terms, it allows voice calls to be transmitted as data packets over the 4G LTE network, rather than through traditional 2G/3G voice channels.
Voice data is digitized, compressed, and transmitted as packets over LTE.
This allows faster transmission (up to 13 Kbps) compared to the older analog method (around 8 Kbps).
Calls connect almost instantly, reducing latency and dropped calls.
Audio is clearer, producing HD voice quality that captures natural tones.
Unlike other voice-over-IP (VoIP) services like Skype, WhatsApp, or Viber, VoLTE does not require a separate internet app and consumes less battery. It works seamlessly on 4G LTE networks and can also support Wi-Fi calling in areas with weak cellular coverage.
💡 Pro Tip: VoLTE allows simultaneous voice and data usage. This means you can browse the web, stream music, or check emails while on a call, which is not always possible on 2G or 3G networks.
Many Xiaomi devices have VoLTE disabled by default. Activating it is straightforward and takes just a few steps.
Open the Phone app on your Xiaomi device.
Dial the code:
*#*#86583#*#*
You will see a message: “VoLTE carrier check was disabled”. This confirms that VoLTE is now enabled.
Go to:
Settings → SIM cards & mobile networks
Find the option “Use VoLTE” and toggle it ON.
If your device has dual SIMs, enable VoLTE individually for each SIM:
Settings → SIM cards & mobile networks → SIM 1 / SIM 2 → Use VoLTE
Once activated, your Xiaomi phone can make HD voice calls over 4G LTE. VoLTE functionality also depends on your network provider and whether they support this technology.
Activating VoLTE brings multiple advantages over traditional voice calling:
Clearer and more natural audio.
Reduced background noise.
Easier to understand even in crowded or noisy environments.
Calls connect almost instantly, eliminating delays typical of 2G or 3G calls.
Reduces the chance of dropped calls during network handovers.
Browse the internet or use apps while on a call.
No interruptions to streaming or downloading during conversations.
Unlike VoIP apps, VoLTE consumes less power because it uses the LTE network directly.
Saves energy during extended conversations.
VoLTE works with Wi-Fi calling, allowing better connectivity indoors or in areas with weak cellular signals.
Ensures a more stable call experience.
Enables advanced telephony features, such as:
Call waiting with HD voice
Conference calls
Enhanced 4G LTE network performance
Most modern Xiaomi, Redmi, and POCO devices support VoLTE. Older models or certain regional versions may not have it enabled.
No, VoLTE uses your voice plan, not regular data. It simply transmits voice as digital packets over LTE.
Yes, you can enable VoLTE separately for SIM 1 and SIM 2, depending on carrier support.
VoLTE compatibility depends on both your phone and the carrier. When traveling abroad, it may work only on compatible 4G networks.
Call Drops or Poor Voice Quality
Ensure you are in an area with strong 4G LTE coverage.
Toggle VoLTE OFF and ON again via Settings.
VoLTE Option Not Showing
Make sure your SIM card supports VoLTE.
Restart the phone after entering the dialer code.
HD Voice Not Working
Check if your carrier supports HD voice calls.
Ensure only one SIM is active if dual SIM mode causes conflicts.
💡 Tip: Restarting your Xiaomi phone after enabling VoLTE often resolves most connectivity issues.
VoLTE (Voice over LTE) is a powerful feature on Xiaomi, Redmi, and POCO phones that significantly improves voice call quality, speed, and reliability. By enabling VoLTE:
Calls are clearer (HD quality) and faster.
You can use mobile data while talking.
Battery life is improved compared to VoIP apps.
Indoor and low-signal coverage is enhanced through Wi-Fi calling.
Activating VoLTE is easy, either through a dialer code or Settings → SIM cards & mobile networks → Use VoLTE. Once enabled, your Xiaomi smartphone will deliver a superior calling experience that is modern, efficient, and reliable.
