There is a well known company that offers cheap international calling from any mobile phone or landline. What's unique about this company is that there is a list of 51 countries that you can call to and from for free. Here are the simple steps to follow:

1) Go to www.marvelousads.com
2) Sign up for free and see if your country is part of that list. If so, just follow the instructions to make free calls!

If this sounds to good to be true, or you feel the quality of the service is not as great, I also use www.intermarvelous.com to make international calls because the rates are cheap and the quality is really good!

Just thought I would help people save money on international calling...:)
