Very good app........
Excellent
I can make calls directly to any mobile number around the world. I love it! Very cheap and clear connections.
Cheap rates on rebtel.. And very good app. I would recommend to use rebtel
PTTlite version is good for me.. apart from been cheap, it works well on my android 4.3 version perfectly without any issue
Nice software
It cheap but call quality isn't that great.you have to dial few times to get your call though. keeps on changing for the call that doesn't go through. Even the operator speaks I still have to pay for that. As soon as I run out of the remaining balance I will uninstalling it.
Good
improved voice
