Voice over 4G (VoLTE) allows you to call with higher sound quality, faster connection and the ability to simultaneously use mobile Internet. However, many Xiaomi owners face a problem: the feature is either absent in the settings or does not work despite operator support. In this article, we will discuss all the ways to enable VoLTE on MegaFon for different Xiaomi models – from low-end Redmi to flagship Mi and POCO.

It’s important to understand that successful activation depends on three factors: device support (chipset and firmware), availability of service from the operator (MegaFon should provide VoLTE in your region), and the correct settings in the phone. We checked the instructions on current MIUI firmware 14/15 and models from 2020-2026, so it will be suitable for most users.

Verifying VoLTE: How to Make Sure Everything Is Configured Correctly

Once VoLTE is activated, it is important to check that the function is actually working. Here are 3 reliable ways to do this:

1. Status bar indicator: During a call, the words VoLTE or HD should appear next to the signal level. On some firmware, the indicator is displayed only at the time of connection.
2. Internet test call: Call any number (e.g., 0500 for MegaFon support) and open YouTube or Speedtest without interrupting the call – if the internet is working, VoLTE is active.
3. Service code: Enter USSD-Team: ##4636## → Phone information → VoLTE status If Registered status – everything works.

If the VoLTE indicator does not appear, but the Internet is working during the call, you may have VoWiFi (Wi-Fi calls) activated, which also supports simultaneous data transfer.

💡

To distinguish VoLTE from VoWiFi, turn off Wi-Fi before a test call. If the VoLTE indicator appears — the feature works over a 4G network, if not — check the settings again.

VoLTE vs ViLTE vs VoWiFi: What’s the difference and what’s better

Modern Xiaomi smartphones support several voice technologies over the Internet.

• 📶 VoLTE (Voice over LTE): Calls are transmitted over the network 4G, non-switch 3G/2G. Pros: fast connection, better sound quality (codecs) HD+), Internet during conversation. Cons: Depends on the coverage 4G, may not be working roaming.
• 🎥 ViLTE (Video over LTE): Video calls online 4G (Pros: high quality video, integration with regular calls. Cons: not supported by all operators, requires separate activation.
• 📶 VoWiFi (Voice over Wi-Fi): Calling over Wi-Fi, useful for weak cellular signal. Pros: works even in basements, saves battery power. Cons: depends on the quality of Wi-Fi, there may be a delay.

On Xiaomi, these technologies can conflict, for example, if VoWiFi is enabled, VoLTE can automatically shut down, and the best option is to activate both options and let the phone choose the best signal.

💡

For maximum stability of communication, we recommend to enable both modes (VoLTE). + VoWiFi) and use Prefer Wi-Fi for calls in settings SIM-map.
