10 vacation mistakes that could be costing you hundreds of dollars

It's hard to disconnect from the world especially when you're on vacay. But that doesn't mean it needs to cost you a pretty penny. Instead of racking up roaming charges, get a sim card. Most newer phones are easy to unlock, allowing you freedom to swap to a more economical prepaid sim card overseas. You can also use your phone on WiFi. Take advantage of free apps like WhatsApp, Skype, Viber, and FaceTime to keep in touch with loved ones for less.
