We have many options to communicate today. Beyond being able to use traditional calls through the mobile, we can count on many programs and devices. For example, instant messaging such as WhatsApp or Telegram, social networks such as Facebook… But if there is something that has changed a lot, it is the calls we make. We have applications to make voice calls and video calls for free from your mobile. In this article we are going to talk about it, we are going to explain how the Wi-Fi calling and what advantages do they have?
What is Wi-Fi calling?
Wi-Fi calls, as the name suggests, are those that use this technology to be able to establish communication. Unlike conventional calls, in which we use the mobile network to call a certain phone number, in this case it is based on applications.
It is something that we can use both on computers and mobile devices, although it is in the latter cases where it is used more. We need install a program, such as WhatsApp, Facebook Messenger, Skype… There are many options. Through these applications we will be able to make calls to other users who also have that application.
We will have to create an account and thus have a user to be able to identify ourselves. In addition, these calls can be simply by voice, but also in the form of video call. They can even be in groups and not only between two people. This certainly opens up a range of options.
To make calls we will not need a phone number or a SIM card. We will only require have connection to the Internet and a compatible application with which we can establish that call.
This has its positive and negative points. First of all, we are going to see what the main advantages of being able to call via Wi-Fi are. There are some factors that undoubtedly significantly improve what we can achieve with a traditional call, with one mobile number to another.
Call when there is no mobile coverage
The first advantage is that we can call without mobile coverage. Let’s think, for example, of a restaurant in a basement, where there is not even a 2G network. If we want to make a conventional call, we couldn’t. The same would happen in any other place where there is no mobile network.
On the other hand, if we make a call over Wi-Fi, it will only be necessary to have a Wi-Fi network available. It is common that today any restaurant has, so in the example that we have given we would not have problems to be able to make that call.
Another clear advantage is cost. Although normal calls today are much cheaper than a few years ago and there are even unlimited calling rates, one way or another we are going to have to pay something. On the other hand, when calling via Wi-Fi this is not the case and there we are going to save a lot.
We will be able call for free from any Wi-Fi network we find. It does not have to be in our house, but in any public wireless network, in a store, restaurant… This will provide a lot of flexibility, as well as being cheaper.
We can also improve call quality. Having a good Wi-Fi connection is essential, but we could achieve better results than making a call in areas where mobile network coverage does not reach well.
In addition, not only will we be able to make a voice call with another person, but we will also be able to make a video call and even a group call. This will improve the quality of communication, make it more diverse and we will not only be able to speak as if it were a conventional call.
The flexibility in terms of Location from where we are going to be able to make calls is another positive factor. It does not matter if we are abroad or anywhere, we will be able to call without problems. This does not happen if we make traditional calls through the mobile network.
The only thing we are going to need is to have a Wi-Fi connection available. From there, it doesn’t matter if we are at home, in a shopping center or in any airport in the world. It is certainly one of the most important advantages.
let’s find a wide range of programs available. Each of these applications can have its advantages, such as being able to use them on other devices, being able to make video calls, several calls at the same time, etc. In addition, with the passage of time they acquire new characteristics.
For example, we can name some of the most popular such as WhatsApp, Facebook Messenger or Skype. We can use them both on desktop computers and also from mobile phones. You simply have to install the program and thus be able to make voice or video calls between users.
But not everything is positive. There are also some negative points that we can take into account. Some of them we will not find if we make a traditional mobile call. They are disadvantages that must be reckoned with and put on a scale what suits us best depending on the case.
Need to have Wi-Fi
One of the clearest negative points is that we are going to need have a Wi-Fi connection available. Although it is true that they are very present in our day to day life and we will find a network in most places, we will not always have access to one that works well.
Without Internet access we will not be able to make a Wi-Fi call. Also, if the signal is very weak, we could have problems establishing communication. This would especially happen if we are going to make a video call, which will require a better connection.
Both people have to use an app
One limitation is that all the people who are going to be part of that call are going to have to have a same program. It does not matter if it is a call between two people or a group call, where many more can participate. All of them will have to install an application, such as Facebook, WhatsApp or Skype.
If we are going to make a conventional call, we would only have to have a mobile phone with network coverage. But in this case we are going to need that additional program to make it work properly.
You can’t be on the move
We can also suffer limitations when communicating online. movement. If we make a normal mobile phone call, we can go on a bus and talk for hours without anything happening. It won’t cut. However, this does not happen when we make a call over Wi-Fi.
Let’s think, for example, that we are connected to the local Wi-Fi network at home and, while making a call, we decide to go outside for a walk. As soon as we are only a few meters away, that call would be cut off as it does not receive coverage from the router.
All in all, Wi-Fi calling is very useful nowadays. They are increasingly used. Of course, as we have seen, it has its positive and negative points. In the end we will have to weigh what improvements we are going to obtain and whether or not it pays off in each case to communicate in this way or make traditional calls.
