- First and foremost. now there is no need to waste time to make a call. Understood nothing? We explain: before, in order to make a call, the system automatically switched the device from 4G mode to 3G mode, which could take about 2 seconds. Now you do not need to switch anything, the device makes a call immediately.
- The second advantage, and no less important, is that the quality of the transmitted sound has improved, in some cases. at times.
- Third: when making a call, you can transfer data in the 4G network. Previously, this was impossible, because, as mentioned above, the device switched to 3G mode.
- The fourth advantage will not be noticed by the majority of users: the number of subscribers that can maintain simultaneous communication with one base station increases.
VoLTE: what is it in a phone or smartphone?
In May 2014, Singapore-based SingTel introduced the world’s first commercial VoLTE service operating in Singapore. Interestingly, initially it worked with only one smartphone. Samsung Galaxy Note 3. Later the technology was developed in other countries. Russia was no exception.
Users often ask the question. what is this very VoLTE? The term VoLTE itself was formed from several words: Voice over LTE, which can be translated as “voice over LTE”. Yes, it is indeed a voice transmission technology, which, in turn, is based on IP Multimedia Subsystem (IMS) technology.
What does VoLTE give? This technology allows you to provide voice services and deliver them as a data stream over LTE, has several times greater data capacity and voice capacity than 3G networks, and even more so 2G. VoLTE also frees up bandwidth.
But all this is lyrics. It is much more important for the user to know what advantages and disadvantages this technology has. We will tell about them.
Disadvantages of VoLTE
- There may be such a problem: when leaving a city where there are no LTE towers, the connection may be lost. You need to switch to 3G mode yourself.
- The second is a higher load on the device itself, that is, it can discharge faster. True, the load is small, so there is no need to worry about the fact that the smartphone suddenly starts to discharge quickly.
On smartphones, VoLTE is turned on by default, and a corresponding icon appears in the status bar, which may have the name VoLTE or, for example, HD, as in our example:
You can disable this function at any time, or, conversely, enable it. We do not see the point of disconnecting, but if you want to do this, then here is a simple instruction for you.
Open the Settings app from the desktop icon.
If you have a different layout of subsections in the “Settings” section, it does not matter. use the search by the phrases “mobile network” or “mobile networks” (without quotes).
Find the line “VoLTE calls” and enable or disable the specified functionality.

Which smartphones support Vo LTE
There are more rumors about new communication and voice communication formats than truth. Therefore, we will try to find out not only about Vo LTE, what it is in the phone, but also what devices support the technology. Today smartphones with support for 4G and all related formats are not uncommon, we will list some of them:
- Samsung, Galaxy series, including the likes of S3 and S4.
- IPhones, starting with the “six”.
- LG G Pro, Optimus.
- Huawei, Sony Meizu.
This list is constantly expanding. Manufacturers understand that in another 2-3 years, 4G networks will become out of competition in the world, so rebranding is needed today. Vo LTE has a single standard, so buy any of the phones that support the service, there is no difference in quality.
The Vo LTE icon appeared on the phone: what is it?
Voice over LTE is a technology for transmitting a voice signal using 4G. High-speed networks of the fourth generation are confidently conquering new countries around the world. With the advent of 4G, the speed of Internet transmission has increased significantly, the quality of communication has changed for the better. The modernization also affected the sound component. With the advent of Vo LTE service, users were able to experience a new, improved voice communication format. From the article you will learn about Vo LTE, what it is and what prospects it has in comparison with previous voice communication standards.
Advantages and Disadvantages
Let’s take a closer look at Vo LTE, what it is in a phone, what advantages and disadvantages it has in comparison with the previous format. Pros:
- The time for making a call is reduced. It would seem that the time from dialing to establishing contact is minimal, but in the case of Vo LTE, this gap is even shorter. The thing is that when making calls without a service, smartphones automatically switch from 4G to 3G mode. The procedure takes 3-4 seconds. And with Voice over LTE support, communication is established instantly.
- The sound quality for voice communication has improved by an order of magnitude. Extraneous noises and vibroacoustic therapy have gone into history, when the interlocutor speaks, you can hear clearer and clearer, and even if his phone does not support standard.
- Now, when making a call, the Internet data will be transmitted over the 4G network, and not 3G, as we said earlier that a phone without Vo LTE automatically switches between standards.
- The last plus concerns rather the communication providers. The number of people using one station will increase.
- The technology is free, does not require special approvals and connections.
With its pluses, the Vo LTE service has a number of disadvantages. First of all, now when leaving the city where LTE networks are not connected, it will be impossible to make calls on the phone. You will have to manually switch the network to 3G. And the LTE coverage area in Russia is at an initial level, many areas still need equipment installation and the construction of related infrastructure.
In addition, users are worried about the increased power consumption when using “Voice LTE”. True, experts assure that the charge will be consumed a little more, but not so critical to sound the alarm.
What is Vo LTE
The development of new wireless technology began back in 2014. over, the first smartphones on which the LTE network was tested were Samsung. The transition to the new regime has already taken 4 years and the process has not been completed. Distribution problems are associated with the complex infrastructure that is required for the full operation of the system. For example, in Russia, not all regions support 4G networks, especially those in the central, densely populated territory. But development work continues, and in the coming years there will be dense coverage with new networks.
Smartphone owners are alarmed by the appearance of unfamiliar inscriptions on the display. The question arises. what does the icon on the Vo LTE phone mean? Here are the main definitions of the service:
- Translated from English Voice over LTE means “Voice over LTE”. 4G is presented as a technology for receiving and transmitting an Internet signal, while the potential of the technology is more extensive.
- Vo LTE transmits voice messages over the high speed LTE network. Compared to previous transmission methods via 3G or even 2G, Vo LTE has a higher capacity, in addition, it provides a higher signal bandwidth.
- It is important not only that the smartphone supports Vo LTE, it is also necessary for the operator to provide a similar tariff. For example, there are still no suitable offers in Beeline.
For sound transmission, the IP Multimedia Subsystem (IMS) technology is used, that is, the IP protocol is used for operation.
What does Vo LTE mean on Samsung and how to disable it
Not all users appreciated the emergence of a new standard for voice over IP traffic, the fact that such a conversation is much easier to track and listen to. There is only one way to protect the privacy of your personal life. turn off the technology on your smartphone.
If you have a Vo LTE badge on Samsung, it means that you are in the coverage area of the LTE network, your operator provides service maintenance, and you can call another subscriber not as usual, over a mobile network, but through the Internet. If for some reason you are not satisfied with these possibilities, disconnect the network. To do this, go to “Settings” → select “Connections” → “Mobile networks” → select Options (in the upper right corner of the three dots) and click “Disable”.
When you go out of LTE coverage, the network will automatically switch from 3G to 4G.
In the first months of testing, the Vo LTE service has established itself as a modern, profitable solution for smartphones. If you see such an icon on your smartphone, feel free to connect and feel the difference in the development of technologies over the past 3 years.
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 better voice communication without extraneous noise and interruptions.
Your device, when VoLTE is on, will use the 4G Internet channel to transmit your voice
At the same time, it is not necessary that two interlocutors have the function at once. even one-sided 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, battery power 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 most 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 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 need to dig a little in the settings of mobile networks. If you now have it enabled, on the top bar of icons there may be a special icon with the name of the technology.
Mobile operators supporting the technology: MTS, Tele2, Megafon, Beeline. Of course, the coverage area does not include all regions. only certain areas, 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.
Let’s talk more about setting up VoLTE for Xiaomi:
- In the settings, go directly to the “SIM-cards and mobile networks” block.
- Set the option switch to the desired position: blue icon. option active, gray. option disabled.
VoLTE is a high-quality voice communication during phone calls. The option removes interference, noise, discontinuities, since the 4G Internet is used as a channel. Traffic is not counted. pay only in minutes. If your phone was released after 2014, chances are it supports VoLTE. You can easily enable or disable the function in the mobile network settings.
VoLTE or Voice over LTE is a voice transmission technology that allows the provision of voice services and delivery as a data stream over LTE. At the same time VoLTE has three times more voice and data capacity than 3G UMTS networks. Many cellular operators support this technology, so when using an LTE-enabled smartphone, you can see the corresponding icon in the status bar.
An example of such an icon based on a Samsung smartphone:
For some reason, some users do not want to use this technology. Why is a mystery, but they want to turn it off. Well, let’s show you how to do it. We will use the same Samsung as a smartphone, although this instruction is also suitable for smartphones from other companies, including Xiaomi, Huawei, etc.
VoLTE Calls switch is on.
Look at the status bar. the VoLTE icon is gone.
Mobile networks are more and more modernized. Communication protocols are continually being improved for better communication quality. Recently, LTE networks can be used as streaming voice data. The technology was created by SingTel and was originally intended for just one phone. However, the borrowing of ideas does not stand still and now a whole galaxy of smartphones support VoLTE technology.
VoLTE. what is this technology, pros and cons
VoLTE (which stands for Voice over LTE) is based on streaming multimedia over IP. The sound is converted to digital and sent via Internet channels to the recipient’s smartphone.
This system allows you to make communication between subscribers fast, sound clear, and communication more pleasant. However, not everything is as smooth as it seems, therefore it is necessary to consider some of the nuances.
The technology has quite obvious advantages:
- high quality sound due to digitization and fast data transfer;
- the ability to use the mobile Internet in parallel to communication;
- fast connection between subscribers;
- in most tariff plans VoLTE is considered not as a consumption of Internet traffic, but as a connection within the network, therefore minutes are written off, and not traffic.
At the same time, the cons also lie on the surface:
- new technology consumes too much battery power, which quickly drains the charge and depletes its resource;
- insufficient LTE coverage area in the country, which means that it can only be used in large cities, this leads to another obvious disadvantage. both subscribers must be in the LTE coverage area.
For a stable connection with VoLTE technology, both interlocutors must be in the LTE coverage area

Starting from 2015, the Big Four operators are gradually introducing VoLTE in the regions and by the end of 2019 the equipment modernization should be completed. At the same time, access to high-quality communication will be available to almost all residents of the country.
For the function to become active, you need to turn on the “Voice and Data” mode
In addition to VoLTE, the ViLTE service is being developed in the world. The principle of its operation is similar to its predecessor, only instead of a voice, a video signal is transmitted. When the subscriber does not have access to the Internet, he is out of the network coverage area or traveling abroad, Wi-Fi Calling comes to the rescue. The name means that voice calls are transmitted via a Wi-Fi network, for which a client application is used.
The latter option is imperfect as it may charge a call per call. In this case, it is more practical to use instant messengers that establish communication through Internet access.
4G networks initially worked only for uploading / downloading data. When making a call, the smartphone automatically switched to 2G / 3G, which took an additional 3-6 seconds and interrupted / slowed down the Internet connection speed. The solution was the emergence of VoLTE technology, which in Russian means “voice calls over LTE”.
Samsung Galaxy Note 8: Meaning of Triangle With Double Arrow Up / Down Icon
- when making a call, the subscriber is connected to a high-speed IP channel, which provides sound transmission in the 7000 Hz range: the voice is transmitted without interference, noise. Conventional telephony provides 3400 Hz;
- VoLTE activation is included in the price of the tariff plan;
- the call does not interrupt the data transfer.
The technology works only when dialing a subscriber in the international format 7 (communication number).
The ability to make a conversation via Vo LTE1 will depend on:
- on the operator’s coverage: both call participants must be connected to tariffs with technology support and be within its coverage area (depending on the area);
- VoLTE support at the smartphone firmware level.
When communicating via an IP channel, the user does not write off the Internet traffic, but the remaining packet minutes.
Despite all the advantages, this does not mean that the solution has no disadvantages. The key disadvantage is the increased battery consumption, in contrast to communication over 2G / 3G networks. This is due to the transmission of data over the IP mowing line.
How to enable and disable
The appearance of the Vo LTE2 icon on the screen at the time of a call indicates that the technology is active. If there is no icon or want to turn off the function:
- go to “Settings” and select “Connection”;
- in the list that opens, tap on “Mobile networks”;
- turn the VoLTE Calls switch to active or negative position;
The way how to enable or disable VoLTE on Samsung A10 and A50 will be different from the solution on Samsung Galaxy S6. This is due to different versions of the custom firmware: smartphones released since 2019 work on the basis of the proprietary One UI interface.
What does the Volte icon mean on a Samsung smartphone
What is the Vo LTE icon on Samsung smartphones? This is a notification about the connection to the technology of voice data transmission in 4G networks over a high-speed IP channel. We will tell you about the principle of operation of the VOLTE, its advantages and disadvantages, the method of shutdown.
VoLTE is an actual way in 2020 to transfer voice calls in digital quality without interference, noise and other things. The technology is supported by all Samsung flagships starting with the Galaxy S4. Budget and mid-budget devices began to receive VoLTE compatibility starting in 2018. Anyone who wants to remove the function can turn it off in the device settings. The function is analogous to Wi-Fi Calling, which requires connection to Wi-Fi networks instead of 4G.
What does the NFC icon mean
This inscription at the top of the screen symbolizes the active NFC module, which is responsible for contactless payment. Such a sensor is possessed by phones of an average and expensive price category. If the module is turned on and ready to pay, the NFC icon is displayed at the top.
Other icons on Android smartphones
This is not a complete list of symbols that periodically appear at the top of the screen. On different phone models, images may differ in graphics or may not look alike at all. Consider several popular models.
What do the icons on the phone of different models mean: types and decoding
The icons on the screen of an Android smartphone are an indicator of any process taking place on the device. They do not appear or disappear for no reason, and necessarily symbolize a certain option. Due to the multifunctionality of modern phones, there are many icons, and all of them are not alike. Inexperienced users often get lost, not understanding what kind of unknown image reappeared in the status bar. To be able to deal with this, we have prepared a guide for decoding images on phones of different models.
What do the icons on the Android screen mean: meaning
There are several classifications of icons, and all of them are responsible for specific properties of the device. tablet or phone. In devices of different models, they look similar, differ only in the features of graphics and pixelation.
For example, an ascending vertical rectangle image of an antenna notifies the person of what cellular signal is available at the location. If the connection is bad, there will be only one antenna division, if it is powerful. 4 or 5, depending on the smartphone.
Classification E, 3G, 4G and H shows what Internet speed is valid in the coverage area where you are. The weakest indicator is E. It appears in areas remote from cell towers. 4G is more and more active in cities, but this coverage has not yet appeared everywhere.
The battery shows the charge level of the device. If it is highlighted in red, then you need to connect it to the charger. If a lightning bolt is drawn there, then the recharging process is in progress. If there is a double lightning, the “Fast charge” mode is active. To help you understand this topic, we have prepared a guide “Icons on Android: decryption”.
What does the Handset icon mean?
The handset in the status bar indicates that a call is in progress.
What the VoLTE badge stands for
Volte is a new development in the field of voice calls. The first phone with this permission appeared in 2014 in Singapore. As of 2021, the technology is developing, but not so rapidly, so it is not implemented in all phones. The main advantage is high-quality voice sound when making calls. This was achieved thanks to stronger communication modules and a powerful information transmission channel.
If you find the inscription “VoLTE” in your status bar, then incoming and outgoing calls are made using modern high-quality technology, and it is available in this region.
The meaning of the letter “E”
This is the initial classification of internet speed. If this letter appears on the status bar, it means that video and music will have to be loaded for a long time, and graphics on some sites will not open at all. Such phenomena are frequent in remote villages and hinterlands.
What does the “H” mean?
This is an indicator of a more stable internet. This technology is completely abbreviated as HSPA. In terms of internet speed, it is faster than 3G. On some phones there is no “H” icon, it is displayed as 3.5G.
What does the VoLTE icon mean on a Samsung phone screen?
It becomes clear that the name of the new technology consists of two parts. The prefix “Vo” is added to the main one described above. So what does the VoLTE icon on the Samsung phone screen mean? It means that the ability to transmit voice messages through the 4G network is connected. The development of a new feature was necessary due to the fact that up to this point 4G networks did not support voice calls. To implement them, the device switched to an older technology. 3G.
Two English words have been added to the name. “Voice over”, which literally means “voice through”. The words were shortened and the literal translation of the name is “voice over the LTE network”. The creator is SingTel. In 2014 Samsung released the first model with the implemented technology. Galaxy Note 3.
The appearance of the VoLTE icon on the Samsung screen indicates that the option is activated. This can only happen if:
- the subscriber is in the home region zone;
- confident signal reception from the operator;
- The SIM card has suitable characteristics;
- the device operates within the specified range.
What is LTE?
This is a new wireless communication standard based on the older ones. GSM \ EDGE. Designed primarily for mobile devices. Oddly enough, these two networks are not compatible, since they operate in different bands and use a different radio interface from each other. The core of the previous network has undergone a complete overhaul and many times improved.
Similar networks are used all over the world. LTE is often referred to as 4G, which is not entirely correct. This technology is not suitable for 4G networks in all respects. The main goal of the changes to which old technologies have been subjected is to increase the throughput. Users have noticed improvements in the Internet. It is enough to compare the capabilities of 3rd and 4th generation networks.
The limit values of such a network are up to 100 Mbps. Of course, in practice, the speed is much lower and does not match the performance of wired Internet. Various factors influence its decrease. Main. distance to signal source.
VoLTE Samsung calls. what are they??
Such voice calls are made via a modern mobile network. In fact, the call is made using mobile traffic, but no additional payment is required. on Samsung smartphones, such conversations are included in the operator’s tariff plan.
The principle of making voice calls is shown in the picture below.
What is VoLTE in a Samsung smartphone
Users of modern smartphones do not always fully know all the capabilities of their devices. They contain technologies that the owner is unaware of or does not understand their purpose. In this article we will talk about what VoLTE is in a Samsung smartphone, how this technology is implemented, why it is needed. Find out which models of Korean smartphones support VoLTE, how to activate or deactivate the function.
VoLTE vs 4G Benefits and Comparison
|one.||Data transfer. For voice transmission. switch to 3G.||Simultaneous transmission of voice and other data.|
|2.||Decreased sound quality when making a call if the Internet is activated.||Sound performance is excellent, no interference or noise.|
|3.||Special applications are required for video calls.||No apps needed.|
|four.||It takes some time to connect with the subscriber.||The connection is instant.|
|five.||Mobile traffic is consumed.||Minutes are included in the operator’s tariff.|
- small distribution. This happens for various reasons: from the capabilities of telecom operators to difficulties with technical implementation. In remote areas, the smartphone user will have to independently switch to 3G in order to make a call. This is not very convenient;
- using such calls will quickly drain your phone’s battery.
How to Disable VoLTE on Android Samsung Phones?
The function is disabled in the smartphone settings. Shutdown algorithm:
- Sequentially go to “Settings”. “Mobile networks and SIM-cards”.
- Select the item with the name “VoLTE”.
- Deactivate slider.
If the owner of a smartphone wants to use the latest technology, but his device does not have the required module, he will have to purchase another gadget. Installing third-party applications will not fix the situation. Also, the problem might be an outdated SIM card. It can be replaced free of charge by contacting the office of the telecom operator.
