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 to be desired.
Have you ever thought that if we connected to a WiFi network, we could solve all these problems? Since some time ago this is possible, we can make calls through WiFi and it is not necessary install any additional application on either phone, receiver or transmitter.
In this article we will show you what steps you should follow to call VoWiFi and all the other points that characterize this new technology.
What is Voice over WiFi and what is this technology for? of telecommunications?
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 is that it is not necessary to apply an application beforehand so that telecommunication can be done between both phones , and as a second important feature we highlight that it is completely free because Internet is used via WiFi by dialing a phone number.
It is necessary to clarify that not all telephony providers offer this service and also not all phones have the option to enable VoWiFi calls enabled at the factory , for those who do not have this option available VoIP calls 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 they have nothing to do with these two technologies. 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 using 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 as it must match the calls via VoWiFi.
While VoIP is a SIP (Session Initiation Protocol) technology, which uses IP data services. In order 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 lies in the way they use the Internet network. For VoIP you don’t need any specific type of Internet, since you can use cellular data or a broadband connection. while for VoWiFi it states 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:
When using a WiFi network, the cost that we will have is practically minimal or zero because our voice is going to be emitted through the mentioned network . 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 place for the phone company to consider it a local call, with this the roaming costs will be very low .
If there is no signal in the place where we are, for example, in a basement, but there is a WiFi network available we can quietly make the call .
There is a greater coverage of WiFi 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 conventional telephone networks , 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.
Without previous applications
When you only need a WiFi network, your phone does not need to have an application in place. The alternative to use WiFi is already incorporated since its manufacture , and if not, we should simply update our operating system so that it can be incorporated into this technology.
This results in a little more protection of our security , since when installing third-party applications spy files are usually installed where they can find out about our privacy.
