    How to Check Your Phone's Data Usage

    Check how much data your phone is using each month so you do not go over your plan limit and get hit with unexpected overage charges.

    1

    Check data usage on iPhone

    ~40s
    Go to Settings and tap Cellular (or Mobile Data on some versions). Scroll down and you will see a list of apps along with how much data each one has used during the current period. At the top you will see your total cellular data used. Scroll to the very bottom to find a Reset Statistics button — your carrier resets data on your billing cycle date, so you may want to reset this counter on the same day each month to keep the numbers aligned.

    Quick Tip

    Look for apps using surprisingly large amounts of data. Streaming apps like Netflix, YouTube, and TikTok are often the biggest data consumers. If you see a big number next to an app you rarely use, check your settings for that app.

    Check data usage on Android

    ~20s
    Go to Settings and tap Network & Internet (or Connections on Samsung phones), then tap Data Usage or Data. You will see a graph showing your data usage over the billing cycle, plus a list of apps and how much data each has used. Some Android phones let you set a data warning or data limit right on this screen.
    3

    Check usage through your carrier's app

    ~27s
    Download your carrier's app if you do not have it already. Verizon uses My Verizon, AT&T uses myAT&T, and T-Mobile uses T-Mobile. Sign in with your account information. Most carrier apps show your current data usage prominently on the home screen, along with how many days remain in your billing cycle.

    Quick Tip

    Carrier apps often show your data usage in real time and are more accurate than the built-in phone tracker, because they match exactly what your carrier is counting toward your bill.

    Set a data warning on your phone

    ~20s
    On Android, in the Data Usage settings, look for Set Data Warning or Data Warning. Enter a number slightly below your monthly limit (for example, if your limit is 10 GB, set a warning at 9 GB). Your phone will notify you when you hit that number. On iPhone, your carrier's app usually handles warnings and alerts.

    Reduce data usage if you are getting close to your limit

    ~34s
    Connect to Wi-Fi whenever you can — at home, at a family member's house, or at a trusted location. Turn off automatic video playback in Facebook and Instagram settings. In Netflix or other streaming apps, go to settings and choose a lower video quality for mobile data. These steps can cut your data usage significantly without changing much about how you use your phone.

    Warning

    Avoid using public Wi-Fi networks (like at a coffee shop or hotel) for banking or other sensitive activities. Those networks are not always secure. Use your cell data or a VPN for sensitive tasks when away from home.

    Your phone plan comes with a monthly data allowance — a set amount of internet data you can use over the cellular network (not counting your home Wi-Fi). This might be 5 gigabytes, 10 gigabytes, or unlimited data depending on your plan. If your plan has a limit, going over it can result in extra charges on your bill or a slowdown in your internet speed until the next billing cycle.

    Data gets used whenever your phone connects to the internet through the cell network rather than Wi-Fi. Streaming videos, scrolling through social media, using maps for directions, and downloading apps all use data. The good news is that when you are connected to your home Wi-Fi or a trusted Wi-Fi network, most of these activities do not count against your data plan at all.

    Both iPhone and Android have a built-in data usage tracker that shows you exactly how much data you have used and which apps are using the most. Checking this number every week or so is a good habit, especially if you have a limited data plan. It helps you catch a runaway app before it causes a surprise on your bill.

    Your phone carrier also tracks your data usage and usually lets you check it through their app or website. Many carriers will send you a text message or notification when you reach 75 percent or 90 percent of your monthly limit — a helpful early warning. You can also call your carrier's customer service line and ask them to tell you your current data usage at any time.

    If you find that you are regularly coming close to your data limit, there are a few practical fixes. You can connect to Wi-Fi more often, adjust your streaming quality to use less data, or turn off automatic video autoplay in apps like Facebook and YouTube. You might also consider upgrading to a larger data plan or an unlimited plan if the savings in overage fees make it worthwhile.
