Facebook started testing its “Find WiFi” feature on its app last year in a few countries. The feature allows you to find businesses nearby that have free, public Wi-Fi. Now, the social network is expanding the feature to all users around the world and rolling it out to both iOS and Android users. When you have this feature on, you’ll get to see not just which establishments have Wi-Fi but also their business hours, network names, and what kind of place it is. But a business will need to opt in to the service on their Facebook Page for you to see them.
