Cell phones were no longer just for making calls, sending text messages, etc., but could be used as a laser meter and even as a spirit level to be able to straighten pictures around the house. Of course, Spanish users have enormous possibilities with these devices.
And the same thing happens with calls, since, beyond conventional calls, it is possible make video calls from messaging apps like WhatsApp or Telegram, but it is also possible to use WiFi calls, a modality available on some smartphones, and which is different from VoIP or VoLTE calls.
Its presence on Android is conditioned by several factors, but It is a great alternative to conventional voice calls which has the advantage of not requiring coverage, in addition to offering great sound quality to users and good stability during the call itself. Of course, this can be very useful in situations where mobile network coverage is not available, but WiFi is available.
Which are?
Its name is quite descriptive. This modality, also called VoWiFi, allows you to make calls from a mobile phone, both on Android and iOS, using the WiFi connectivity that exists at home or anywhere. This allows you to not depend on mobile network coverage to call other people. One of its great advantages is that these types of calls are completely free, so they do not involve any type of cost, beyond that of renting a WiFi network at home. This means that if you don’t have minutes in the tariff, you can save by talking from home.
The sound quality is quite good, sometimes even better than that offered when speaking via mobile services, although this also depends on your upload and download speeds. Generally speaking, most users talk about greater stability and sound quality, which is due to the use of WiFi infrastructure, which is more stable than mobile networks.
Indeed, in the event of natural disasters such as earthquakes or hurricanes, the mobile network infrastructure can fail, but WiFi calls can be made as long as you can access one of these networks. The same thing happens in rural areas, where if you have a signal at home, there will be no need to depend on mobile networks to communicate.
For practical purposes, making one of these calls is virtually the same as making a conventional call, both in terms of the application used and the general appearance of the interface. However, if you have a good internet connection, performance can be even better. And this is its main difference compared to the calls offered by messaging platforms.
How to use WiFi calling
On Android, this option is available in Settings, in the Network and Internet section, within the Calls and SMS section. However, even if this option is enabled, The operator used will also need to offer this service to its users., because otherwise they cannot be used. If the option does not appear, it is very likely that the mobile or operator is not compatible. Major carriers have this option, and those that don’t may include it over time.
If they are available, you will not have to do anything other than activate the option. You will also not need to register anywhere or download any application, since it is something that is built into the operating system. Just open the Phone app and call someone to see if it works. Likewise, it will be possible to receive calls from other users.
Enable Android WiFi Calling
There is virtually no change in the appearance of these calls compared to conventional calls, so you will need to look at some details to know if they work. The most important thing is that WiFi calling icon will be displayed in notification barwhich is represented by the phone icon and the WiFi signal icon just above it, has no loss.
These types of calls are not the same as VoIP, which is the method used by applications like WhatsApp, Telegram or Skype, since in this case users must download and use the same application. This also differs from VoLTE calls, which use 4G technology in calls and are dependent on mobile coverage. With VoWiFi calling, what is offered is simple: being able to call from the conventional phone app using WiFi.
