Rebtel

No WiFi or 3G support for windows phone 8 users, wasted $10 to use my phone to call a phone and that phone call another. If they can not make app for windows phone like they have for android and iPhone they should not make it in the first place. May be their developers are incompetent to make a decent one for windows phone.

It's a really nice app for international calls. The call quality is fantastic. It's also really affordable

I just love the easy call and connection......never using phone card.

Good for long distances international calls , but sometimes it doesn't connect and will have some poor connections..

Fantastic service.making it possible to reach my family and friends in Nigeria

Just so bad, everything.

Clear and fast connection.

Rebtel is very good and cheap.
