Introduction to VoWiFi and eSIM
Traveling abroad can be exciting, but staying connected with family and friends back home can be expensive. Traditional international calls can rack up a high bill, but there is a cheaper and more efficient solution: VoWiFi (Voice over Wi-Fi) technology combined with an eSIM. In this guide, we will explain how to configure your eSIM to make and receive free calls over Wi-Fi during your international travels.
What is VoWiFi?
VoWiFi is a technology that allows you to make and receive voice calls over a Wi-Fi network instead of the traditional cellular network. This means you can maintain a stable, high-quality connection without relying on cellular coverage, which can be especially useful in areas with weak signal or during international travel.
What is an eSIM?
An eSIM (electronic SIM) is a digital SIM card that integrates directly into your mobile device, eliminating the need for a physical SIM card. eSIMs offer flexibility and convenience, especially for travelers, as they allow you to change operators or data plans quickly and easily.
