VoLTE (Voice over LTE) has become the standard for today’s smartphones, allowing voice calls over 4G networks instead of the outdated 2G/3G. For Xiaomi phone owners, this means clearer sound, faster connectivity and the ability to talk and use mobile Internet at the same time, but not all devices of the brand support this feature – especially among budget and outdated models.
In this article, we will discuss in detail which Xiaomi, Redmi and POCO smartphones are officially compatible with VoLTE, how to check support on your device, and what to do if the feature does not work. You will also find an up-to-date table by series (2026) and answers to frequent questions - from the differences between VoLTE and ViLTE to the peculiarities of working in Russian networks.
What is VoLTE and why is it important for Xiaomi?
VoLTE (Voice over LTE) is a fourth-generation (4G LTE) voice technology that, unlike traditional calls that use 2G/3G, provides:

- ⚡ Instant connection – the time of setting the call is reduced by 5-7 second 1-2.
- 📶 Parallel operation of the Internet – you can simultaneously talk and use mobile data (for example, Google information while talking).
- 🔋 Battery savings – the phone doesn’t switch between networks, which reduces the load on the communication module.
For Xiaomi, VoLTE support has become a priority since 2018, when the brand began to actively explore the European and Indian markets, where operators massively abandoned 2G/3G. However, in budget lines (Redmi A, Redmi Go), the feature is often absent or requires manual inclusion.
- 🚫 Regional restrictions – some devices for China are not certified for European operators.
- 🔄 Outdated firmware - without updates MIUI The function can be disabled at the software level.
- 📡 Incompatibility with the operator – not all Russian providers (for example, Tele2) fully support the technology.
