Problems with Conventional Calling

Consider yourself in a basement, trying to do an urgent call and walking here and there to make your device catch signals. Frustrating, isn't it? The problem behind this is the weakening of frequencies, which are used in connecting our calls while penetrating through the walls. And when you are in a basement this problem further increases.

 

This leads to another big problem of exposure of the human body to electromagnetic waves which are measured by SAR Values. In short greater the SAR value of a device greater is its tendency to search for signals in a low network area, making our body more exposed to EM Waves. Samsung is the company offering the lowest SAR values in its device but the problem persists.

 

The other problem with cellular network calls is being faced by people travelling abroad frequently. You might not have an international telephone line. Also, the top-ups for international calls, provided by your telecom carrier are not at all budget-friendly.

Since modern problems require modern solutions, this is where VoWiFi comes into play.

VoWiFi is the transmission of voice over a WiFi network. It is a free service used to connect to any network provider without the use of a cellular network. Not only for calls, but it can also be used to send SMS and images to any person. 

It seamlessly switches between cellular and WiFi network to provide uninterrupted connection. That means if your network signals are weak it will switch to WiFi network and vice versa.

 

The technology, as of now, has proven to be the best solution to the problems with cellular calling. Now you don't have to search for signals in a basement. All you need is just a WiFi and a smartphone, supporting VoWiFi.

For people travelling abroad, you can use the WiFi connection of Hotel, Airport, Home or Office to take advantage of this technology.
