Until not long ago making a phone call from one country to another it cost us a lot of moneyNot to mention if we wanted to make a call to another continent. The bills at the end of the month from the telephone companies were an unpleasant surprise in terms of the amounts we had to pay.

What methods to make free calls exist?

Among the different methods that currently exist to be able to communicate for free, we can name the following:

WiFi Calling

WiFi Calling is a technology that has been used for some years, it consists of using a WiFi network through which we can make voice calls to another phone that has Internet access at the time of the call.

At first, this communication system could be similar to that carried out through some applications such as WhatsApp or Skype, but this is not the case since WiFi calls have some advantages over these applications.

We can mention the following:

For example, not you need to download no application to be able to call
The user that receives the call must also not have an application any download on your phone to be able to establish communication
By not having to download any app, the dialed numbers will be the same as those that exist in the contact directory of our phone.
In this way we save many steps with respect to applications that provide a similar service.
WiFi Calling is compatible with operating systems Android and also with iOS
Call quality is very good. so interference and delay do not exist in most cases.
Roaming costs are considerably reduced when we are abroad and use this type of technology.

But as technological development they also present disadvantages, of which we can say:

Not all carriers offer this kind of technology
You need to have relatively new phones that can support Wifi Calling

VoIP

This acronym comes from “Voice over Internet Protocol“. This technology is based on provide voice communication and other multimedia datasuch as video, over an Internet protocol.

In order to establish communication with this system, users must have a software-based IP phone, or a VoIP phone based on a special exchange.

Among the main advantages offered by this mode of communication we can say:

Widely used by companies since can have full control about the telecommunications that occur in them, you can call a VoIP number or a PSTN type telephone number.
Reduce the cost in this concept for the companies. If we talk about people, telephone providers offer plans in which this service can be added, which does not exceed €60 on average.
need of much smaller facilities to those of traditional telephony

If we have to mention the disadvantages of this system, we would have to talk about:

As information travels in data packets through network protocols, many times these do not always arrive at the destinationalso do not guarantee the time it will take the same to reach their destination.
Although it is true that they have a good speed, but if we focus on the reliability and security these are not so good at the time of a thorough analysis
As a disadvantage we also have to mention that It is not a technology that is open to everyoneAt the moment it is used in private networks, especially companies.

VOLTE

VoLTE is a technology similar to the previous one, but instead of using a network protocol to send voice data, LTE is used, which is a wireless connection system through broadband that transmits data to our mobile devices.

The main advantages of this system are:

You can make calls and stream files in multimedia formats on a high quality.
If there is no WiFi Internet connection, with this technology our Android devices will be able to connect and make the calls we need.
The LTE coverage network is much wider than a WiFi network

Among the disadvantages of this system we can name the following:

When establishing a voice communication, we will need data to connect to the Internet. This data is much more expensive to connect to a wireless Wi-Fi network.

Through third-party apps

One of the most used methods to make calls from our Android devices is through the use of third-party applications.

As we already know, These apps can be downloaded from the Google Play Store. The steps are very simple and intuitive, we will simply have to choose between the options of “Install” and then “Open“.

Among the most used apps currently we can mention WhatsApp, Telegram and Skype. These applications work through an Internet connection in which data packets travel in multimedia format and also voice.

When we use these applications we will be able to call practically without spending moneyfor this, the mobiles that want to connect will have to have the software previously installed.

Among its advantages we can mention that:

it just takes a good Internet connection and a phone with relatively new android (as for its version) to be able to use this telecommunication system.
The protocols used for communications allow group messages to be sent and know when they have been read or listened to.
Installation is freeso it is accepted by almost all people, that is, almost all phones today have one or more of these applications installed.
Messages are end-to-end encryptedThis means that no intruder can access them.

The disadvantages of these are:

To establish the call they need the mobiles yes or yes they have the applications installedotherwise the software will not work.
The The quality of the communication will depend on the quality of the connection. who have mobile phones at that time, if at least one of them does not have good Internet coverage, communication will have many interruptions.
