Voice Over WiFi  What is it? + What is it for? + Alternatives ▷ 2020

Communicating by mobile phone in a traditional way has become a headache today. Telecommunications antennas are increasingly saturated, the plans offered by telephone providers are increasingly expensive and their services leave something to be desired.

Have you ever thought that if we connected to a WiFi network we could solve all these problems? For some time this has been possible, we can make calls through WiFi and it is not necessary to install any additional application on either of the two phones, receiver or transmitter.

In this article we will teach you what steps should you follow to call by VoWiFi and all the other points that characterize this novel technology.

What is Voice over WiFi and what is this telecommunications technology for?

Voice over WiFi is a technology by which we can make calls from one phone to another through the WiFi network.

The main characteristics of this system is that it is not necessary to apply an application previously so that telecommunication can be carried out between both phones, and as a second important characteristic we highlight that it is totally free because Internet is used through WiFi by dialing a telephone number.

It is necessary to clarify that not all telephone providers offer this service and also not all the phones come with the factory built-in option to enable VoWiFi calls, for those who do not have this option of VoIP calls available we will have to install an additional free application.

VoWiFi vs VoIP Are they the same technology? Main differences

Some people confuse VoWiFi with VoIP, but these two technologies have nothing to do with it. The VoWiFi is a function already included in the mobile through your operator. VoIP is an external service or tool that you must configure or install through an app.

To use VoWiFi our mobile device requires a program granted by the service provider and a subscription to it In which the SIM card must be included since it must be the same as the calls through VoWiFi.

While VoIP is a SIP (Session Initiation Protocol) technology, which uses IP data services. To be able to establish a call via VoIP It is not necessary to have a SIM card, but if an IP connection, which can use mobile data or WiFi, these calls do not depend on the service operator.

Another difference is in the way they use the Internet network. For VoIP you do not need any specific type of Internet, since you can use cell phone data or a broadband connection. while for VoWiFi it establishes precisely that you have to use a WiFi connection.

What are the main advantages of using WiFi Calling?

There are many advantages when using WiFi Calling, we can list some of them:

Costs reduction

When using a WiFi network the The cost that we will have is practically minimal or null because our voice will be broadcast over the network mentioned. We will not use data, we will simply have to activate this service with our telephone operator.

Also if you need to make national and international calls, it will depend on where you are located so that the telephone company considers it a local call, with this the roaming costs will be very low.

More coverage

If there is no signal in the place where we are, for example, in a basement, but there is a network of WiFi available we can calmly make the call.

There is greater WiFi coverage than 3G / 4G networks in the country, in this way we solve the problem when we are in areas where telephone companies are not very interested in having good coverage.

Decongests the transmitting antennas

Another advantage is that it decongests the use of telephone networks conventional, the antennas will not be saturated when we decompress the use of traditional calls. This is a benefit both for us, who use WiFi, and for people who need to communicate in the traditional way since their communications will have fewer interruptions.

No previous applications

As we only need a WiFi network, our phone does not need to have an application installed. The alternative to use WiFi is already incorporated from its manufacture, and if not, we should simply update our operating system so that it can be incorporated into this technology.

This results in protecting our security a little more, since when installing third-party applications, spy files are generally being installed where they can find out about our privacy.
