**Check your data usage**

Understanding your data usage is extremely important, especially if you're on a limited data plan. Keeping an eye on how much data you're using can prevent you from encountering pricey overage charges or having your data speeds throttled. Here's how to check how much data you've been using with tools built into iOS:

Step 1: On your iPhone or iPad, open the Settings app.

Step 2: Tap the Cellular option. Note that it may be called Mobile Data or Cellular Data in some cases, depending on your device, iOS version, and regional settings.

Step 3: Scroll down to the section labelled Cellular Data.

Step 4: From here, you can see an overview of your data usage for the current period, including the total data used, data used while roaming (which usually costs more), and data used by each of your apps, sorted from the highest to the lowest. A toggle switch beside each app allows you to disable cellular data access for that app to help reduce your data usage.

# Reset your data usage counters#
When you check your data usage, the Current Period indicator can be a bit misleading. It may sound like this automatically resets with each billing period, but that's actually not the case. The numbers simply keep accumulating until you reset it manually, and there's no way to schedule this — you'll have to set a reminder for yourself every month if you want to ensure the numbers are for a specific time frame. Here's how to reset your data usage counters:

Step 1: On your iPhone or iPad, open the Settings app.

Step 2: Tap the Cellular option. Note that it may be called Mobile Data or Cellular Data in some cases, depending on your device, iOS version, and regional settings.

Step 3: Scroll all the way down to the very bottom of this screen.

Step 4: Note the Last Reset_ date and time. This indicates the beginning of the Current Period for all the numbers above this.

Step 5: Tap Reset Statistics. This clears all of the data counters, as well as the Current Period call time. Note that the Lifetime call time is tied to your specific iPhone hardware and cannot be reset.

# Turn off cellular data
If you find yourself approaching the limits of your monthly data allotment, you may need to take the extreme approach and disable cellular data entirely. This will limit your communication options to voice calls and SMS/MMS text messages whenever you're away from a Wi-Fi network, but it will also guarantee that you won't be charged for any extra data use. Off really means off in this case. Here's how to quickly toggle cellular data:

Step 1: From your iPhone or iPad home screen, swipe down from the top-right corner to bring up the iOS Control Center. If you're using an iPhone with a Home button, such as an iPhone 8 or iPhone SE, swipe up from the bottom instead.

Step 2: Tap the green button in the top-left panel of the control center to turn off cellular data. The button should turn grey.
