Pros: Probably the least expensive alternative to paying pricy international rates with your cell phone company.
Cons: I have noticed a slight delay on calls which can become annoying.
Summary: This company is so easy to use. I was worried about giving them my credit card number because I had not heard of them before, but I've been using them for over two years now and have never been overcharged! There is no monthly fee and you pay by the second, so you save some extra cash that way! As I mentioned above, there is a slightly noticeable delay when using the service, but it's probably a delay of only a half-second and can easily be ignored! In short, I have recommended this company to many of my friends and family because it's the best plan around.
