In the wake of the devastating earthquake and tsunami, AT&T & Verizon initiated a noble cause of offering free calls to Japan to their customers in USA. Although it’s a great initiative for US customers, people around the world also need a way to do the same. To make it possible anyone in the world to call Japan, TringMe is now offering free VoIP calls to Japan from its Blackberry application and Web Portal, i.e. http://tringme.com.
So, regardless of where you are in the world, you can make personal calls to your relatives and friends in Japan to express your support (and hopefully do not use this service to make business calls).
