What is TelFi?
TelFi is MCI's Wi-Fi calling service enabling MCI subscribers to make and receive a phone call through any Wi-Fi connection. By installing TelFi application, instead of using the carrier's network connection, subscribers can stay connected to the MCI network via a Wi-Fi network. In other words, with TelFi on your phone, you will stay connected using your home Wi-Fi connection, or any Wi-Fi hotspot you happen to be on when you're out and about, such as at a cafe or library or even in an airplane! It's like a regular phone call, and you still use the same phone numbers, call logs and call dialer screen, without using any other application.
