My Mom bought me a Magic Jack about two weeks ago but I could not use it because I do not have a spare telephone unit. I bought a unit a few days ago before the typhoon and thought I can use it now that I have a the unit, but no... I do not have an internet connection to install the software.
I have heard of this product a few months ago from a friend because she uses this to call her parents in the US. Magic Jack allows you to call for free to any US telephone number just by using your computer. To read more about this product, click on this link.
