Wi-Fi calling: Make calls even if you don't have mobile coverage

Wi-Fi phone calls are free.

What are Wi-Fi calling and how are they useful?

Calls over Wi-Fi are an alternative to life calls that they do not need network coverage to connect and talk on the phone.

And, as the name suggests, the Wi-Fi calls connect through a nearby Wi-Fi network, regardless of the infrastructure behind it, be it ADSL, Fiber, 4G, WIMAX or other connection methods. **.

Therefore, its operation it is not very different from that of instant messaging or video calling applications. In both cases, the connection is made via the Internet.

This might suggest that, in a broad sense, the Wi-Fi calls aren't that different from audio calls offered by services like WhatsApp or Telegram. However, there are some important things to keep in mind.

The first is that the Wi-Fi calls are made by keeping our phone number, and although they do not need mobile network coverage or use the operator's telephone towers, the their price is the same as that of a normal call.

It should also be said that, in general, call stability is superior to those made through telephone networks, since we do not depend on the network coverage of our operator. In that sense, it is worth saying that we can make Wi-Fi calls to any phone number and make a call via Wi-Fi, even if the other person is not using this feature.

Another advantage over third party internet calling services is that DON'T è need to change the application to make calls: Smartphone manufacturers that include this feature in their mobile phones have adapted theirs matching phone apps to allow you to make Wi-Fi calls from said app.

How much do VoWiFi calls cost?

Wi-Fi calling: Make calls even if you don't have mobile coverage

You can make Wi-Fi calls from your mobile phone app.

As I mentioned before, the Wi-Fi call service does not incur an additional cost for customers. Operators offering this utility in Spain they do not charge an additional fee to customers who decide to activate it, and in fact this is included - and activated - in most of the contractual rates.

Furthermore, calls as such have no additional cost. The price for Wi-Fi calls is the same of a normal call. Which therefore implies that if you have a unlimited calling plan, Wi-Fi calling will be free.

Operators that support Wi-Fi calling in Spain

Not all Spanish operators offer the service VoWiFi –O Voice Over WiFi **. Today I am four telephone companies that allow their customers to make Wi-Fi calls.

amena: the VoWiFi service is available at no additional cost to all Amena customers who own a compatible smartphone. It is not possible to make Wi-Fi calls abroad.
Movistar: Wi-Fi calls Movistar are included at no additional cost for all customers of the contractual rates.
O2: the same conditions as Movistar are maintained. Therefore, the O2 Wi-Fi call is included at no additional cost for all contractual rate customers.
Orange - Le Wi-Fi calls Orange are available at no additional cost to all contract customers. Not available on prepaid plans.

At the moment, other operators such as Vodafone, Lowi, Pepephone or Simyo have not confirmed whether they will offer calls via Wi-Fi in their voice and data plans.

What kind of mobile phone can you call over Wi-Fi?

One of the reasons why the Wi-Fi calls aren't that popular is the fact that not all mobile phones support this function. But even when they do, each of the operators has a set of requirements that they make some VoWiFi cell phones cannot be used to make calls of this type with certain telephone companies.

That is why, on the web pages of the operators, we will find lists of mobile phones compatible with Wi-Fi calls. Below, we list the models supported by each company:

How to activate Wi-Fi calling

Wi-Fi calling: Make calls even if you don't have mobile coverage

A phone call with an Android mobile.

If you have made sure that the your operator offers the VoWiFi service and that your mobile phone is compatible, you must not activate any kind of extra option for your rate. You must only enable Wi-Fi calling on your mobile.

Whatever your Android phone is, the process for activating Wi-Fi calls will be the same. You just have to follow these steps:

Go to your mobile's Settings.
Enter the "Connections" or "Networks" section.
If available, the "Wi-Fi Call" option should appear. Flip the switch to enable the option.

That's all. Now, as long as the mobile is connected to a Wi-Fi network, all phone calls made will be made via Wi-Fi and you will not depend on network coverage.

How is the quality of VoWiFi calls?

Not depending on the coverage, the quality of Wi-Fi calls can be much higher to that of conventional calls, thanks to a more stable connection and the fact that this type of calls it can also be done in areas with no coverage such as garages, basements or rural areas with bad signal.

Under similar conditions, the differences will not be too obvious in terms of audio quality.
