VoLTE calls: what they are, what advantages they have and what operator they have

An action that remains essential in the use of mobile phones is to make calls. Also in this field there have been many improvements over the years, being one of the most important VoLTE calls , of which you have heard on some occasion heard or read something. For many people it is something totally unknown.

What are VoLTE calls and how do they work? Here we tell you all about it, so that we can know more about their importance. We will also tell you the operators that currently have these types of calls available in the case of Spain.

What are VoLTE calls


VoLTE calls are also known with 4G calls or voice over LTE . This is an improvement in calls, thanks to an improvement in the mobile network. This provides voice calls with higher sound quality, which is the main feature in this case. In addition, a faster call establishment is also obtained in this case.

On the other hand, users are given the ability to navigate in 4G + at maximum speed , even while calls are being made. This is something that operators allow, being Orange one of the first operators in Spain to have introduced such calls in the market.

Before the arrival of VoLTE calls, operators made use of GSM or UMTS networks to transmit voice communications between phones. While the 3G and 4G network was responsible for transmitting this data over the Internet. The development of this technology allows data to be transmitted with greater speed. Thanks to this technology, the operators give us a service capable of transmitting the voice in compressed packets over the Internet.

What advantages do these calls offer?

Being an improvement, we can see that VoLTE calls leave us with a series of advantages that are of importance. They allow users to enjoy certain changes, which those who have experienced the change from one technology to another have probably experienced. The main advantages that leave us this type of calls are:

  • It is possible to make clearer calls with high definition voice, even in noisy environments.
  • 4G + data rate is maintained during calls.
  • It is possible to dial a phone number and contact it almost instantly.
  • You can make WiFi calls using your home WiFi network and continue the 4G network call when there is no WiFi.
  • Battery consumption is lower using VoLTE calls.
  • Rich conversations: During the calls, services known as RCS (Rich Communications Services) are offered, including functions such as video calls, data transfer, location or images.

The advantages in this case are clear , so we can see the many improvements that have been introduced in this case in VoLTE calls.

As for the inconveniences we find in this case, they are quite few, but many of them have been corrected over time. At first, when VoLTE calls were launched, it was common for calls to be disconnected . In addition, they were something that was only possible to use in calls between the same operator. So they are limitations that over time have been corrected, allowing them to function properly.

Compatible phones with VoLTE calls

One of the most important limitations was that in the beginning very few phones were compatible with VoLTE calls. Luckily, this is something that has been corrected over time, so there are more and more Android phones that have compatibility with these types of calls. Although there are still a few brands that make use of them.

In Android it is Samsung that is betting more on VoLTE calls , since a large part of its mid-range and high-end phones have such support. Some of the signature phones with support are:

  • Galaxy A50
  • Galaxy A40
  • Galaxy A70
  • Galaxy A10
  • Galaxy A80
  • Galaxy Note 8
  • Galaxy Note 9
  • Galaxy S8
  • Galaxy S8 +
  • Galaxy S9
  • Galaxy S9 +
  • Galaxy S10
  • Galaxy S10e
  • Galaxy S10 +
  • Galaxy S7
  • Galaxy S7 Edge
  • Galaxy A9 2018
  • Galaxy A20E
  • Galaxy Xcover4
  • Galaxy A8

Other brands that are leaving us with this support are Sony, LG and Huawei . The three have several devices that support this type of calls, also among their most recent models, so we can find phones in Spain that have such support, if you have interest. Models we can find are:

  • Huawei P30, P30 Pro and P30 Lite
  • Huawei Mate 20, Mate 20 Pro and Mate 20 Lite
  • Huawei P20 and P20 Pro
  • LG Q7
  • LG G7
  • LG G8S ThinQ
  • LG K30
  • LG K40
  • Sony Xperia XZ1
  • Xperia XZ2 and XZ2 Compact
  • Xperia XZ3
  • Sony Xperia 1
  • Xperia XA1, XA2

Operators offering these calls

As we mentioned, Orange was the first operator in Spain to support VoLTE calls . With the passage of time, new operators have been added, although the pace with which they are advanced. It is also in the case of Orange where we find the largest catalog of compatible phones with this function.

Vodafone is another operator that has supported VoLTE calls . Four years ago the operator included this option in Spain, as we told you in its day. Until recently, they were the two main operators that supported this technology. Although a few days ago Movistar was the last to join this list, supporting VoLTE calls and WiFi calls.

In this way, the three main operators in Spain already have support for this type of calls. It would be normal for others to add up over the months, although the speed with which this has advanced is being much slower than expected. But we do not doubt that it will soon reach new operators in Spain.

To access these VoLTE calls you just have to have a compatible phone and a fee with that operator . None of them charge money to make use of them. So you will not have problems or additional costs for using them on your phone.
