With the evolution of the smartphone era, VoIP has progressed a lot and the smartphone users now have many ways to make free local and international calls. The following are 9 mobile apps that enable you to make voice and or video calls for free or at extremely reduced rates:
Viber
This app is really awesome with cool features included in it so it is at the top of our list not only because it enables you to make calls completely free, but mainly because it is integrated with your phone book. That means you do not need to sign up for the Viber service or open an account like on Skype. The company has launched this app for android too which means that existing users of the iPhone version will be able to make free calls and send free text messages to their friends with Android phones.
NetTalk
NetTalk you can also record conversations and import your phone book and favorites, then call them for free over Wifi or 3G but unfortunately NetTalk lets you call all landlines in the U.S and Canada for free. The call quality is excellent and just like Viber, the app is free. With Yep, this one is pretty much a no-brainer.
Tango
While the Tango app is the best we’ve seen for video chats over 3G so far as we all know that mobile video calling is not an entirely new concept but Tango specializes in free video calling across iPhone and Android. It is the only app that allows users on both platforms to video call. There are both iOS and Android versions available of the Tango app as well, so there can be plenty of cross-platform chatting if necessary.
