I also use Skype. They can call on my cell for free unlimited!!!!!!!!!!!!!!

You open an skpye a/c here and also open another Skype for them. In your a/c you buy US-Canada unlimited 7.95$ for 3 months and don't forget to do call forwarding. Put you cell no. for call forwarding even if you are not online, when they double click on your ID, you cell phone rings, talk unlimited as long as they have power in Nepal. Or if they have a laptop they can buy a mobile broadband just like At&T and Sprit have it. I think it cost around 500 Rs. a month in Nepal. They can call you anytime if Laptop is charged.
