One of the most important innovations in the mobile telephony sector is the WiFi Calling service which allows you to make voice calls via WiFi, bypassing the mobile network (Vodafone, Cosmote, Nova).
As long as your mobile is connected to any WiFi network, it can make and receive calls.
WiFi Calling will mostly appreciated by these who do not have a good mobile signal in their area. Travelers will also be benefited from this service. Especially Europeans traveling to countries outside the European Union or International travelers in the EU (where roaming charges are increased)
Once the service is initially activated by the provider and then on the mobile, calls will be encrypted and routed over WiFi.
Advantages of WiFi Calling
Superior call quality in areas with weak mobile signal.
Very big savings for those travelling or about to travel to countries outside the European Union. Those of us who have used roaming know that a few minutes call can cost a few tens of euros.
With WIFI everywhere, the need to roam can be reduced or even eliminated.
Battery savings. WIFI requires less energy than a “conventional signal” to “carry” the audio data of a call.
Compatibility with various devices. WIFI Calling is also available on other devices, for example an android tablet.
Disadvantages of WiFi Calling
The quality of the call depends on the WiFi network. The use of other devices during the call and our distance from the router (e.g. in another room with a weaker WiFi signal), can affect the quality of the call
Inability to locate us in case of an emergency. If we need to call an emergency number such as 112, it will make it harder to locate us as the services will not be able to know where we are.
Security. Although calls are encrypted, they are vulnerable to some attacks that target the router we are connected to.
Incompatibility with some devices. Wifi Calling is a new service and is not available on older devices.
