It can be extremely expensive to make an international phone call, even for a domestic call especially for many of us that are using iPhone now. As the users of iPhone, it is important for us to know some of the free applications that can save us a lot of pocket money which allows free phone call to anyone or to anywhere in the world.

Viber is a new application which is getting more and more popular now due to the booming of iPhone industry. This application currently only works on iPhone, but does not work on other popular phone systems like Blackberry or Android, and without a video chat feature, maybe in future will do. The Viber uses our phone number as a username, so as long as we can remember our phone number, then we can just use it as a username straight away. It doesn’t look like Skype that will need us to create another separate account with username to remember.

So, there is no reason for you to pay for international calls to friends and family just by just persuade them to install this compatible app in their iPhone. In fact, once you have installed the Viber application, it will automatically detect and showing which people in your contact list are also using this free app, thus making you convenience to know who you can call for free.

Another application you can use to make a free call from your iPhone is Skype, as mentioned just now you will need a Skype account. This means you can make video calls or phone calls from your iPhone to any users with Skype account or to other app users for free over the WiFi, Internet connection or 3G connection network systems. This application is very popular feature in iPhone especially iPhone 4. Besides for iPhone or PC, this application is also largely used in other digital devices because it also works with iPad, iPod Touch, Android, and other Skype supported systems.
