VoLTE in the phone: what is it, how to turn it on and off


Recently, so many new technologies are being born that you can't keep up with them. But sometimes you still come across incomprehensible names and start 'googling' them, like, for example, the VoLTE option. She is already relatively old, but not everyone is familiar with her.

A little about VoLTE in simple words

How the VoLTE function works: it transmits the voice of the interlocutors not through a regular cellular channel, as with ordinary calls, but over the 4G Internet. At the same time, the operator does not count the traffic (number of MB) – you pay per minute at the rate that is currently on your number. That is, the function is free – you just get a better voice communication without extraneous noise and interruptions.

VoLTE connection

When VoLTE is enabled, your device will use the 4G Internet channel to transmit your voice

At the same time, it is not necessary for two interlocutors to have the function at once – even unilateral support will give positive changes. During a call, you can safely 'surf' the Internet at a high 4G speed (with regular calls, you are immediately switched to 3G automatically).

The option has drawbacks, of course. First, the battery energy is quickly lost (you must have a large battery).

Secondly, you have to manually switch between network types (3G, 4G). If only 4G technology is turned on, but you leave its stable zone, for example, go out of town, the phone will stop receiving incoming calls. For this reason, users often turn off VoLTE.

Which operators and phones support the option

The technology was first launched in 2014 by a Singaporean operator. Then this option was supported only by Samsung Galaxy Note 3. Now it is even in budget models released after 2014, including phones from companies Xiaomi, Apple, ZTE, Asus, Sony and others.

The top bar may display a VoLTE icon

To find out if your phone supports VoLTE or not, you just have to dig a little in the settings of mobile networks. If you now have it enabled, there may be a special icon with the name of the technology on the top bar of icons.

Mobile operators supporting the technology: MTS, Tele2, Megafon, Beeline. Of course, the coverage area does not cover all regions – only individual regions, including the capital.

How to enable and disable the function

For different mobile 'operating systems' and for smartphones from different brands, the course of action will be different.
