- Tango:
Tango application is also free calling service. It uses the same address book as that of the device, synchronizes with it and shows a tango tag against the contact if they are registered to tango hence with just a click you can place a free call to the tango user. This synchronizing feature is not available in the Skype. It works with iPhone, Android, Windows Phone, Windows PC. It can be downloaded freely from app store or android market place and registering on tango is quiet simple and easy.

- Viber:
Viber application also allows free calling and sending messages. It’s a lot simpler than Skype but it you can’t make video calls from it and there is no desktop client for talking to those on a computer but it does have some advantages, such as the lack of need to create an account. Viber just uses your mobile number to make the calls (although the actual call is made over the Internet) and similar to tango viber also uses your existing phonebook numbers instead of having to create and add new contacts, as on Skype. If you just want to talk to someone using an Android or an iPhone (a version for BlackBerry phones is in works), Viber is a lot easier and simpler choice.
