Your iPhone will always use Wi-Fi when it's available, but when there's no Wi-Fi network to connect to, your phone can use up your mobile data fast.

Fortunately, Apple gives you a handful of tools to manage your data usage, to avoid hitting monthly data caps, or incurring overage fees.

You can use the iPhone's Settings app to turn off data entirely, or you can choose specific apps to disable data service. And for times when you want to quickly toggle data off for a brief time, you can turn on Airplane Mode.
