How Much Data Do I Need?

The average smartphone owner used 19 gigabytes of data per month in 2024, according to a study by communication technology company Ericsson.

But you may not need that much. Stick with surfing the net over Wi-Fi whenever possible and a reasonably priced 5GB plan may be just fine.

How to check your current data usage

You can view how much data you use by looking in the settings of your phone. Most phones track overall data usage. They also break it down by app, so you can see how many of your precious gigabytes are being drained by Spotify or YouTube.

Find data usage settings on your iPhone or Android

To view how much data you’re going through, dive into settings. Find the "cellular" or "network/internet" section, and look at overall data usage and data by the app.

On an iPhone, the "current period" of data usage doesn’t correspond with your most recent billing cycle. You’ll have to reset it to zero and start from a specific date to get an accurate picture of how many gigabytes you use in a month.

Similarly, an Android allows you to manually pick a time period to monitor.

How much data streaming uses

Video and music streaming apps are data guzzlers. But it’s hard to tell how much you’re using in the moment. We break it down by the quality tiers of a few familiar apps.

How to cut back on the data you use

Now that you know what you use, you can reduce data by surfing at home and taking time off demanding apps.

Use Wi-Fi when possible

You can save the mobile entertainment for home (or the local coffee shop). When you connect to Wi-Fi, you stop using cellular data. That means you can stream, download and upload content without cutting into your data allotment.

A slick move is to download your favorite albums or playlists within your music streaming app while on the home Wi-Fi, then take the grooves on the road in offline mode.

Adjust phone settings to keep you in check

Once you know how much data you use, you can cut yourself off or let your device do the work. From your phone’s settings menu, you can turn off certain apps so they don't use cellular data, or you can toggle on data-saving options within the settings menus of common video and music apps.

You'll also want to check the settings on your social media apps, which have become increasingly dominated by video content. A never-ending stream of video reels can make an hour fly by — all the more reason to stop autoplay if the app allows you to turn it off. If not, you might want to watch the clock while you swipe through reels.

Scrolling through Instagram, which has become Reels-heavy, uses about 1 to 2GB of data per hour, according to Eskimo eSIM, a travel eSIM card seller.

When to revisit your data plan

After you've made adjustments — to your apps' behavior and your own — you can determine how many gigabytes you actually need. A good rule is to wait a month or two for your usage to reflect your new habits. Then, check your bill or your phone's data usage meter. If your usage is well under your current plan’s limits, it might be time to switch plans — or even providers.
