Touch base by making a call home: Landing in a strange and unfamiliar country – possibly for the first time and probably on your own – can feel very intimidating and isolating. Make sure your mobile phone is charged and loaded with credit, so that once you've arrived at your new accommodation, you can make a quick call home.
If you're feeling homesick, calling is a comforting way of reminding yourself that the world actually isn't that big of a place. And it serves the double purpose of letting your family and friends know you've arrived safe and sound.
