We had a computer friend over for dinner last week - raving about some new thingy he attaches to his computer - and then it can work as a local phone. Seems he bought a few of these things - going to ship them overseas - use them here - whatever. Seems like lots of work when you can use Skype for free? And the charges for calling a phone instead of a computer are very minimal ???
PLUS - you can get a phone number - so that people in other countries can call you - and you can prepay credit for them ...
Check it out - it's a wonderful service
