iPhone fans are going wild for simple trick that can save you from shock bills every month

IF you’ve ever been lumped with a shockingly inflated phone bill over your mobile data usage – you need to know this trick.

Costs can quickly balloon when using cellular internet – especially if you’re abroad, downloading a large file or are streaming a Netflix show.

Newer iPhone devices can switch between WiFi and mobile data automatically.

This is so users can have the smoothest web experience possibly, with the web page or Netflix show transitioning pretty seamlessly between the two.

But it can get costly, if iPhone users are unaware and their data plan is small or worse, non-existent.

That’s why Apple has given iPhone users the option to make sure their devices don’t automatically make the switch.

Simply go into Settings > Mobile Data (or Cellular in the US) > WiFi Assist and turn the toggle off.

This will stop your mobile data being drained while you’re unaware.

iPhone owners might also want to turn off the two toggles below it.

If the iCloud Drive toggle is switched on, it means the iPhone will use mobile data to transfer documents and data to and from the cloud.

While the iCloud Backup toggle being on means that when users aren’t connected to WiFi, the device will automatically use mobile data to back up your phone to the cloud.

However, Apple warns that this “may cause you to exceed your data plan”.
