Not sure what to turn off? Looking for an idea of what uses data on iPhone? For example, you’ll still be able to access downloaded content in Apple Music, but you won’t be able to download new music. In iOS, you can also turn mobile data on or off for specific apps and reduce data usage for maps, social media apps, email, video streaming and more. Simply go to Settings > Cellular and turn the Cellular Data toggle off. It’s very simple to completely turn your iPhone or iPad’s mobile data off.

Mobile data usage is measured in megabytes (MB) and gigabytes (GB). Think apps, your Internet browser, email and syncing to the cloud.

Mobile data gives you an Internet connection anywhere as long as you’re connected to a cellular network. Mobile data allows your phone to access the Internet even when you’re not on Wi-Fi.
