UPDATED ✅ Do you want to know the concept of VoWiFi and how this method works to call for free? ⭐ ENTER HERE ⭐ and discover everything ✅ EASY and FAST ✅

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

Have you ever thought that if we connected to a WiFi network we could solve all these problems? For some time now this has been possible, we can make calls over WiFi and no additional application needs to be installed on either phone, receiver or sender.

In this article we will teach you what steps should you follow to call by VoWiFi and all the other points that characterize this new 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 features of this system are that it is not necessary to apply an application previously so that the telecommunication can be carried out between both phonesand as a second important feature we highlight that it is totally free because the 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 from the factory with the option to enable VoWiFi callsfor those who do not have this VoIP call option available we will have to install a free additional 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 each other. 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 coincide with 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 mobile data or a broadband connection. while for VoWiFi it establishes precisely that a WiFi connection must be used yes or yes.

What are the main advantages of using WiFi Calling?

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

Cost reduction

When using a WiFi network the cost that we will have is practically minimal or null because our voice is going to be broadcast through the network mentioned. We are not going to 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 so that the telephone company considers it a local call, with this the roaming expenses 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 the 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 prior applications

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

This has the consequence of protecting our security a little more.since when installing third-party applications, spy files are generally being installed where they can be informed about our privacy.
