Take advantage of free WiFi hotspots. Many coffee shops, restaurants, hotels, and even train stations offer complimentary WiFi. "This offers visitors many options that don't cost a thing while traveling abroad. Starbucks and McDonalds, for example, are well-known chains that can be found in most countries around the world and offer free WiFi to customers," says Bisesto.
An app to try for staying connected is called WiFox (available only on Android). It shows Google Map locations near you with protected WiFi networks, revealing the password so you can get online. This is a great option to use at airports, where it often shows you the WiFi password for airline lounges, which have much stronger networks than the free (and sometimes time limited) WiFi available to all travelers. A similar app for iPhone users is WiFi Map.
