There are lots of apps that can go a long way in staying connected. Local SIM is an application that helps to get connected to local cellular network provider (carrier) while traveling or moving to another country.
AirHelp is an easy-to-use mobile app that helps passengers receive compensation if a flight is delayed, canceled, or overbooked. The app allows you to store your boarding pass in one location and preloads all necessary data for airline compensation forms. No more tracking down booking reference numbers and other miscellaneous details from various emails and paper documents; in a few clicks, you can go from delayed to on your way to getting paid! It also stores multiple boarding passes at once — perfect for families traveling together or long journeys with connecting flights and multiple tickets.
Another great app is one that offers free daily news podcasts: just download the day's episode when you have WiFi at the hotel or at a coffee shop, and then you can listen offline on the plane, car, walking — wherever! And when NPR gets a little depressing or boring — or you just really want a daily news update under 10 minutes and with some personality (think "The Skimm" of podcasts) — try TheNewsWorthy, which makes staying up to date easy, convenient, and fun.
