    So I am going on vacation to a place where there is no cell service, but WiFi. Is there an app where I can make calls using strictly WiFi (like T-Mo)? I have an AT&T 8520.

    I tried Vonage Mobile (as I have Vonage Home) but it only works with a cell network signal.

    I searched, but didn't get an answer. Google Voice, seems like it is the same, needs a cell network.

    Thanks!

    T-Mo is the only US carrier that offers UMA calling over Wifi
