In today’s era, mobile phones have become an important part of our everyday life. But sometimes there is difficulty in making calls due to weak network signal inside the house, basement, hilly areas or remote areas. In such a situation, WiFi calling technology has emerged as an effective solution. The question is, what is WiFi calling and how does it make calls even without mobile network?
WiFi Calling is a feature in which WiFi network is used instead of mobile tower for mobile calls and messaging. That is, if there is no network in your phone, but WiFi connection is present, then you can easily make and receive calls. This technology proves to be very useful especially in those places where mobile signal is difficult to reach.
According to technical experts, WiFi Calling works through Internet Protocol. When the user makes a call, the voice is converted into data and reaches the telecom operator’s network through the Internet. From there it is sent to the other person like a normal call. The user does not feel any difference in this process and the quality of the call also remains the same as a normal call.
A big advantage of WiFi Calling is that it does not require any separate app. If your smartphone and telecom operator support this feature, then it can be easily activated by going to the phone’s settings. Many major telecom companies in India are providing this facility to their customers.
Apart from this, international calling also becomes easier with WiFi Calling. If you are abroad and connected to hotel or home WiFi, you can make calls to India without roaming charges. However, during this period the calling charges remain the same as included in your existing plan.
However, the quality of WiFi calling completely depends on your internet connection. If the WiFi network is slow or unstable, calls may be interrupted or delayed. Additionally, not all older smartphones support this feature, preventing some users from using it.
