Have you noticed a new VoLTE icon on Xiaomiβs notification panel and you donβt know what it means? Or suddenly your voice disappeared during a call and this acronym appeared next to the network indicator? Donβt worry, this is not a mistake, but a sign of modern voice technology. In this article, we will discuss in detail what VoLTE is, why it activated on your Redmi, POCO or Mi, how to turn it on (or turn it off), and what to do if you have problems with connection.
VoLTE Technology (Voice over) LTE) β This is the standard for voice transmission through 4G-The network that replaced the old 2G/3G. It provides clearer sound, faster connectivity, and the ability to talk and use the mobile internet at the same time, but many Xiaomi users are asking why the icon came on its own, how to remove it if it interferes, and whether it affects battery consumption. The answers to all these questions are below.
What is VoLTE and why is it needed in Xiaomi?
VoLTE (Voice over LTE) is a technology for voice calls over a fourth generation (4G LTE) network, unlike traditional calls that use 2G or 3G networks, VoLTE allows:
- π Call with quality HD-voices (broadband audio codec) AMR-WB), Which makes sound more clear and natural.
- π Connect to the subscriber 2-3 times faster (the time of connection installation is reduced from 5-7 seconds to 1-2).
- π Use the mobile Internet during a conversation (earlier, when calling the Internet was turned off).
- π Save battery power, as no switching between networks is required 4Gβ3G ring-bell.
On Xiaomi smartphones (including Redmi Note 10/11/12, POCO X3/X4/X5, Mi 11/12/13), the VoLTE icon appears in the status bar when:
- π± The phone supports technology (virtually all models after 2018).
- π‘ Your mobile operator (MTS, Beeline, MegaFon, Tele2) supports VoLTE in your region.
- π§ The function is enabled in the settings of the smartphone (sometimes activated automatically after the software update).

VoLTE vs Wi-Fi Calling: Whatβs the difference and whatβs better
Many people confuse VoLTE with another technology, Wi-Fi Calling, which, while both functions improve communication quality, they work differently:
| Characteristics | VoLTE | Wi-Fi Calling |
|---|---|---|
| Type of network | 4G/5G mobile network | Any Wi-Fi network |
| Quality of communication | Depends on 4G coverage | Depends on the speed of Wi-Fi. |
| It works without. SIM-map | β No. | β Yes (at some rates) |
| Support for operators | MTS, Beeline, MegaFon, Tele2 | MTS, MegaFon, Beeline (Tele2 - limited) |
| Battery consumption | Low. | Medium (depending on Wi-Fi) |
On Xiaomi smartphones, both features can be used simultaneously. For example, if you are in a place with poor 4G coverage but there is stable Wi-Fi, the phone will automatically switch to Wi-Fi Calling.
To enable Wi-Fi Calling:
- Go to Settings. β SIM-maps and mobile networks.
- Choose. SIM-map.
- Activate the option of Wi-Fi Calls.

If you have a weak mobile signal but you have good Wi-Fi, Wi-Fi Calling will be more reliable than VoLTE, but VoLTE is better when traveling, because it is not dependent on Wi-Fi availability.
VoLTE on Xiaomi in 2026: current trends
In 2026, VoLTE technology is becoming the standard for all modern smartphones, including the Xiaomi line.
- π‘ Shutdown 2G/3G: MTS and MegaFon have already begun decommissioning second- and third-generation networks in major cities, meaning that without VoLTE, calls could stop working.
- π Support 5G: On new models Xiaomi (Xiaomi 14, Redmi) K70) VoNR (Voice over New Radio) is an analogue of VoLTE, but for fifth-generation networks.
- π Security: VoLTE uses encryption IMS, What protects conversations from listening better than the old standards.
- π Roaming: Not all operators support VoLTE roaming. Please check with your provider before traveling abroad.
In 2026, operators are actively switching to IP-telephony, so disabling VoLTE on Xiaomi is not recommended - this can lead to communication problems in the future.
