Have you ever noticed that while you're on the phone, the Internet suddenly slows down or disappears? Or that the voice of the person sounds like they're talking from a barrel? Chances are your Xiaomi doesn't use VoLTE technology, the communication standard that solves these problems once and for all. But what is it really like, and why are smartphone makers, including Xiaomi, actively embedding it in their devices?
VoLTE (from Voice over) LTE) — It's not just a marketing term, it's a real breakthrough in mobile, unlike traditional calls that are passed over outdated ones. 2G/3G VoLTE uses high-speed networks 4G/LTE This means that your Redmi or POCO It can simultaneously support voice communication in HD-And high-speed Internet, without any breaks or losses, but how do you know if your Xiaomi model supports this technology? And what if the operator doesn't provide it.
What is VoLTE and why is it important for Xiaomi owners?
VoLTE is a technology that transfers voice calls from legacy 2G/3G networks to modern 4G networks, and the main advantage is that voice is now transmitted digitally, not in analogue, as it used to be.
- 🎤 Clean sound without noise and distortion – as if the interlocutor is near, and not on the other side of the city.
- ⚡ Instant connection – the call is connected to 1-2 seconds against 5-10 second-in-second 3G).
- 📶 There is no “fall” of the Internet during a conversation – you can continue to download files or watch videos.
- 🔋 Battery savings – the phone doesn’t switch between networks, wasting energy.
For Xiaomi, VoLTE support has become especially relevant after many operators began to turn off networks. 2G/3G favorably 4G/5G. Without VoLTE, your smartphone risks being left without the ability to call – even if it has one. 4G-For example, in the Redmi Note. 10 pro POCO X3 Pro without activated VoLTE calls may simply not work in some regions.
⚠️ Note: If your Xiaomi does not support VoLTE, after shutting down 3G You'll lose the ability to make regular calls by the operator!
What Xiaomi smartphones support VoLTE: the full list
Virtually all modern Xiaomi models released after 2018 support VoLTE. However, there are nuances: some budget devices (for example, Redmi 9A) may have limited support depending on the region.
| Xiaomi model | Support for VoLTE | Notes |
|---|---|---|
| Xiaomi 13/13 Pro/13 Ultra | ✅ Yes. | Supports VoNR (voice over 5G) in addition to VoLTE. |
| Redmi Note 12 Pro+/Pro | ✅ Yes. | Requires MIUI upgrade to version 14+ for stable operation. |
| POCO F5/F5 Pro | ✅ Yes. | VoLTE works out of the box, but you may need to manually configure APN. |
| Redmi 10A/10C | ⚠️ Partially. | Depending on the operator and region, in some countries, VoLTE is software-enabled. |
| Xiaomi Mi 11 Lite | ✅ Yes. | Supports Dual VoLTE (Two Calls) SIM-mapping). |
To find out if your model supports VoLTE, check the specifications on Xiaomi’s official website or use GSMArena. Note that even if your smartphone supports the technology, it can be blocked by firmware (especially in global versions for some regions).
How to enable VoLTE on Xiaomi: step-by-step instructions
Activation of VoLTE on Xiaomi usually takes no more than a minute, but the process may vary depending on the version of MIUI.
- Open the Settings. → SIM-maps and mobile networks.
- Choose yours. SIM-card (if there are several).
- Find the VoLTE option (or Improved Calls, HD-call-up).
- Activate the switch. If you don't have an option, update the firmware.
If the VoLTE item is not on the menu, try the following steps:
Update. MIUI last-minute|Check if your operator supports VoLTE.|Reset network settings in Settings → Reset → Resetting network settings|Install an alternative firmware (e.g. Xiaomi.EU)|Contact the operator to activate the service-->
Some models (such as the Redmi Note 11) may need to enter a special code to force VoLTE to turn on:
##86583##After entering, the hidden VoLTE Provisioning menu will open – select the Enable VoLTE option.

VoLTE vs VoWiFi: What’s the difference and what’s best for Xiaomi
Along with VoLTE, VoWiFi (voice over Wi-Fi) is often mentioned, both of which improve call quality, but work differently:
- 📡 VoLTE – uses a mobile network 4G/LTE. It works wherever there is operator coverage.
- 🌐 VoWiFi – Voice over Wi-Fi, useful in areas with poor mobile signal (e.g. basements or outside the city).
On Xiaomi, both technologies can work simultaneously. For example, in Xiaomi 12T Pro, when a weak 4G signal is used, the call will automatically switch to VoWiFi if you are connected to Wi-Fi.
- Go to Settings. → SIM-maps and mobile networks.
- Choose. SIM-map → Wi-Fi call.
- Activate the option and follow the operator’s instructions (SMS confirmation may be required).
💡
If VoWiFi doesn’t work, try turning off the VPN or firewall – they can block voice traffic.
Problems with VoLTE on Xiaomi: causes and solutions
Even if your Xiaomi supports VoLTE, there may be failures, and here are the most common problems and solutions:
| Problem. | Possible cause | Decision |
|---|---|---|
| VoLTE is not included in the settings | Outdated firmware or regional restrictions | Update MIUI or install firmware for another region (e.g. India instead of Global) |
| Calls are interrupted or the sound is interrupted. | Poor 4G coverage or conflict with Dual SIM | Turn off the second. SIM-map or switch to one network 4G |
| The Internet goes missing during a call | The operator does not support Dual VoLTE | Use one. SIM-map or disable VoLTE for the second |
| Impossible to make a call after the update | Failure in IMS settings | Reset network settings or reboot your phone |
If none of these methods worked, check if your carrier is blocking VoLTE for your fare. For example, Tele2 in some regions only provides VoLTE on unlimited minute rates.

VoLTE and 5G: How Technology is Evolving in Xiaomi’s New Smartphones
With the arrival of 5G networks, VoLTE is beginning to give way to the more advanced standard, VoNR (voices over 5G). Xiaomi's new flagships, such as the Xiaomi 14 or Mix Fold 3, are already supporting this technology.
- 🚀 Lower latency (latency) during connection.
- 🎧 Spatial sound support for more realistic conversations.
- 🔄 Smooth transition between 4G and 5G disconnected.
However, VoNR is only available in a limited number of countries (e.g. China, South Korea and some regions of the United States), and operators in Russia and the CIS are just beginning to test the technology. If you plan to buy a new Xiaomi with 5G support, check with the operator whether VoNR is available in your region.
💡
Even if your smartphone supports VoNR, without the right carrier infrastructure, the technology will not work, and VoLTE remains the standard for voice communications on 4G networks.
The future of voice communication: what awaits VoLTE in smartphones Xiaomi
Experts predict that by 2026, most carriers will completely abandon 2G/3G networks, leaving only 4G/5G. This means that VoLTE will become a mandatory requirement for any smartphone, including budget models of Xiaomi.
For Xiaomi, that means:
- 📱 All new models, including the Redmi and POCO) Will support VoLTE by default.
- 🔄 Budget smartphones will receive hardware support VoNR for readiness 5G-network.
- 🌍 Regional firmware will become universal - without reference to the operator.
If you’re planning to buy Xiaomi “years in the future,” be sure to check VoLTE and VoNR support. For example, the Redmi Note 13 Pro+ already features a Snapdragon 7s Gen 2 modem that’s fully ready for future communication standards.
