How to enable VoLTE And VoWiFi In Unsupported Countries

Voice over LTE (VoLTE) and Voice over WiFi (VoWiFi) are two advanced communication technologies that allow you to make high-quality voice calls over cellular networks and WiFi connections, respectively. However, these technologies may not be available in all countries or on all devices. In this guide, we will discuss how you can enable VoLTE and VoWiFi in unsupported countries.

What is VoLTE and VoWiFi?

VoLTE is a technology that allows you to make voice calls over a 4G LTE network instead of the traditional 2G or 3G network. It offers better call quality, faster call setup, and improved battery life compared to your normal voice calls. VoWiFi, on the other hand, enables you to make voice calls over a WiFi network, which can be particularly useful in areas with poor cellular network coverage.
