People are just realising Facebook has a hidden free Wi-Fi button that could save you from data disaster

FACEBOOK has a little-known Wi-Fi feature that could save you from data issues next time you’re out.

There’s nothing worse than worrying you might run out of data on your iPhone or Android device.

It could mean missing out on WhatsApp messages – or if you’re not careful, you could be stung by extra data charges.

A free way around it is Wi-Fi of course.

But it’s knowing where a Wi-Fi hotspot is available that’s the problem.

Your Facebook app actually has a tool that shows you where Wi-Fi is available near you.

Obviously you’ll need a tiny bit of data to use this.

Once you’re there, you can use it to catch up on messages, emails and everything else.

How to find free Wi-Fi hotspots

To find free Wi-Fi hotspots near you, start by opening the Facebook app.

Tap on the Menu button in the bottom right.

Scroll down and select Settings & Privacy.

Look for Find Wi-Fi.

A map will then appear showing hotspots near you.

All you need to do is find your way to the location to get connected.
