one more tip: Skype always works best when you are connected on a wire cable to the internet. If you have a weak wifi signal, you may experience broke up conversations. But either way is great.

I also have a US skypein number where people can call me in the US and rings at my skype account anywhere in the world where I am. Of course you'll need to be online at the time to answer the incoming calls. You will then be available to people via a regular US telephone number and they don't have to have a Skype account to reach you.
