Voxox is an application that is used to make international calls using credit provided by them.It is available on both android and ios. THE company supply 25 credits( Upto 1 dollar) which can be later on increased.It can also be used to make fake calls using international number over wifi.
The app has a brilliant voice clarity. This app do not stops or hang . It also uses a very little space on your phone.The credits can also be increased just by watching small videos.It gives a tough competition to voxofon and is better than it in some places.
Best app to make free international calls. Strongly recommended
