WiFi Calling Plan

Wi-Fi Calling is a service for smartphones which, just as it sounds, allows you to call over a Wi-Fi network.

Consequently, you’re not using the cell tower to place the call, which means that you don’t need a cellular service. When placing a WiFi call it’s just like placing a regular call, without logging in or using an app. Your carrier and phone will determine if you can call through WiFi or not.
