How to make free international calls

When using any app, keep-in-mind that although they are free to use - data charges may still apply.

For apps that require you to enter a number, you'll need to remember to enter the '+' followed by the country calling code of the number you want to call. For example to call a German registered number, it would need to start with calling code:+49.

You may already have one or more of the popular free international call apps on your phone, such as WhatsApp, Facetime or Skype - but which one has features that work for you?
