Don’t let freakishly high international texting or overage fees cut you off from the world. This app uses the Internet (rather than your SMS plan) to send messages, so you can send friends back home updates.
Tablets are kind of pointless when you can’t find a hotspot. Solve that problem with this app, which tracks down free and for-pay networks near you. Unlike most of its kind, the app doesn’t require you to go online to find the info—a major perk since you’re, you know, looking for wifi to get online.
