The social networking giant had begun testing a "Find Wi-Fi" option last year on mobile only for iOS users in select countries.

"We're beginning to roll out 'Find Wi-Fi' everywhere in the world on iPhone and Android. We launched it in a handful of countries last year and found it's not only helpful for people who are travelling or on-the-go, but especially useful in areas where cellular data is scarce," Alex Himel, Engineering Director at Facebook, wrote in a blog post late Friday.

"'Find Wi-Fi' helps users locate available Wi-Fi hot spots nearby that businesses have shared with Facebook from their Page.

"So wherever you are, you can easily map the closest connections when your data connection is weak," the post added.

To find Wi-Fi hotspots, open your Facebook app, click on the "More" tab and then "Find Wi-Fi".

Once in the "Find Wi-Fi" tab, you may need to turn it on.

Users can then browse the closest available hotspots on a map, and learn more about the businesses hosting them.
