Well, I'm glad I found a thread with many replies about this topic. I asked this over at another thread and it was sorted moved into a specfic phone section, probably because of my suggestion for it to be moved.
Anyhow, I'm on Virgin Mobile now, switch from post paid TMobile and wanted to go with a cheaper alternative WiFi calling with Google + GrooVe IP.
The call quality is bad, very bad so far. I hear everyone without issues, but everyone complains they hear echos, delay or it like locks up, then drops the call. I'm using the paid version of GrooVe IP but that doesn't matter much.
So guess, I just have to go with the unlimited package for $55 and make calls over network.
Still beats my TMobile bill every month, plus, now I can actually afford to buy a new phone whenever I want.
Does anyone have another app or alternative method to try before I make the switch to unlimited. My case might be different since I'm on a strong ISP network and my WiFi connection should be great only one device and its sitting about 2 feet away.
Thanks everyone
