Learn how you can connect to your friends via Wi-Fi even if you're not connected to the network

Before proceeding with this explanation you may wonder what is Wi-Fi connection and how is it different from a normal call?!
The latter uses wireless cellular services, while Wi-Fi connection uses only the network you are connected to.
If you are in a remote location without a signal, you can make calls using Wi-Fi, and you will also be able to send SMS messages through the network when the feature is enabled.
Before you apply the steps below, make sure that your phone is connected to a specific network:

First open the phone settings and press Connections.



Then press the Wifi calling option.



Then you will find that the service is not activated, activate it directly.



You will then receive a confirmation notice that you will send the location information. Click OK to continue.



Wi-Fi is now enabled on your device. You can choose whether you prefer to connect to the latter or to the telephone network.



You can then make and receive calls over the network, both audio and video.
Note: Not all devices have this feature as well as phones that are then purchased from the operators.
