As you know, OPPO has been rolling out Color OS for most of its devices, while some of them only get VoWiFi. Telecom operators like Reliance Jio and Airtel has already started its operation of VoWiFi services.


What is VoWiFi?

VoWiFi is a technology which helps to increase the call quality by using your Wi-Fi network. It will help for users who have less cellular reception. For example- network may be less if you are living in the basement of a building, or urban areas where networks are congested. The most interesting part here is that there is no separate app required for this, the default dialer is only required. The recipient needs not to be on VoWiFi. He can be on any networks like 2G/3G/4G/VoLTE.
