The quality of most of the calls were really bad - I even used the premium quality and over wireless. I tried it a while (3 months) and often (3 times a week) and came to the conclusion that this app/service is not usable. There's too much delay and noise while you talking. I tried another VOIP provider along telmy without such problems and even cheaper. I expect a way better service if I pay 7 c/m.
