You might not think of skype as a travel up at first, but trust me, it makes sense. When you’re abroad, calling someone back home can cost you a lot. We all know that international call rates are insane. Skype is your best option in situations like that. Wherever you’re staying will probably have free wifi, so calling your family back home, or calling someone abroad will be absolutely free. Of course, there are other apps, you might want to try Viber or perhaps you’re one of those weirdos who still tries to call people on facebook, but Skype has the best connection, and lately, the best animations for chats. So why bother with anything else, when you most likely already have Skype installed on your phone.
