Skype turns the internet into your own personal telephone line. The software is free and easy to download. Calling different Skype users anywhere in the world is free and can be done done without much fuss as long your internet connection is good. I am finding easy to be in touch with my friends and family since I am using skype .
The only time you pay is when the other person you are calling is not having Skype facilities or access. For heavy users of Skype you can go for Skype premium or just subscribe package where you buy minutes. So never miss chatting or seeing your family from anywhere you are.
