You are travelling halfway around the globe and the first thing you want to do is call your friends or even your loved ones to tell them where you are. E-mails would take a longer time to reach so I would prefer to get international calling cards to phone back. They are great for people who do not want to go overboard with their budget. They come in the prepaid format , giving you the pinless dialling option and you can even buy just 40 minutes of talk time! If you run out of credit, the cards give you the option to reload.
