WiFi calling allows users to make regular calls in regions with poor or no connectivity by using Wi-Fi networks. This service is only available if your telecom provider allows WiFi calling and you have a good Wi-Fi connection.

When network coverage is poor, compatible phones will access the Wi-Fi network to make normal calls via the telecom provider to which they are enrolled. Tizeti Network Limited is the only firm I heard of that provides this service in Nigeria right now. However, most telecom carriers in India, including Airtel, Reliance Jio, and Vodafone Idea, enable WiFi calling. This service is provided at no additional cost by the telecom carriers.

Benefits of WiFi Calling

  • Unclog Cellular Network — In densely populated regions, carriers prefer WiFi calling. It enables businesses to decongest their traditional cellular networks.
    No Extra Charge — In some regions, Airtel is presently providing the WiFi calling service at no additional cost.
  • HD Quality Audio — Some carriers may not offer VoLTE or HD voice functionality in remote or sparsely populated areas. WiFi-calling, on the other hand, allows consumers to make HD calls.
  • Expansion in-network coverage without additional major expenditure – It is a clever concept to broaden network coverage without investing in high-end infrastructure.

If WiFi Calling is enabled on the smartphone, it will make regular voice calls over the linked Wi-Fi network. For example, if you’re in a building’s basement and have poor network coverage, but strong Wi-Fi, you’ll still be able to make normal phone calls. This service aims to improve call quality while decreasing call drops. The WiFi calling service uses the VoIP (voice over Internet protocol) network rather than the VoLTE (voice over LTE) network to make calls.
