Here’s how to use Facebook to find a Wi-Fi connection anywhere

TwitterFacebook

Facebook is rolling out a new feature to help us save on data and locate open Wi-Fi networks, no matter where we are. 

It’s called Find Wi-Fi, and it shows network-needy users a tailored hotspot map of their immediate area, highlighting locations where they’ll be able to find a connection. The feature was tested for iOS in a few countries last year to positive reviews, so Facebook is releasing it to all users around the world on both iPhone and Android.  

It’s not all wide-open public Wi-Fi — the maps are made up of businesses that have shared with Facebook from their Page — but it’ll help you pick out which coffee shop would be best for a pitstop if you’re in an unfamiliar place.  Read more…
