Travel data usage varies enormously by app: maps and messaging cost only a few megabytes per hour, music runs roughly 40 to 150 MB, social feeds land between 200 MB and 1 GB, and high definition video streaming burns through 2 to 4 GB or more every hour. A single hour of HD video uses more data than an entire week of navigation and messaging combined, which is why one or two heavy apps decide the size of plan you need.

This guide is about the per app numbers specifically, the exact data cost of the popular apps you will actually open abroad, so you can predict where your gigabytes go. For total trip sizing and traveller profiles, see our companion [how much data do I need for travel guide](/magazine/how-much-data-do-i-need-for-travel/); this piece zooms into the individual apps.

## How much data does each app use per hour?

The table below is the heart of this guide: typical per hour data usage for the apps travellers open most, as of 2026. Exact figures shift with app version, quality settings, network speed and content, so these are realistic ranges rather than fixed constants. What stays stable is the relative order, and that order is what decides your plan size.

| App or activity | Typical data per hour | Category |
|---|---|---|
| Google or Apple Maps navigation | 3 to 10 MB | Very light |
| WhatsApp text and photos | 1 to 5 MB | Very light |
| Web browsing and email | 30 to 60 MB | Light |
| WhatsApp voice call | 30 to 50 MB | Light |
| Spotify streaming | 40 to 145 MB | Light to moderate |
| Instagram or Facebook feed | 120 to 220 MB | Moderate |
| Video call (WhatsApp, Zoom, FaceTime) | 200 to 300 MB | Moderate to heavy |
| TikTok default | around 840 MB | Heavy |
| Instagram or TikTok Reels | 600 MB to 1 GB | Heavy |
| YouTube 480p | 500 to 700 MB | Heavy |
| YouTube 720p | 1.5 to 2.5 GB | Very heavy |
| Netflix or YouTube HD (1080p) | 2.5 to 4 GB | Very heavy |
| Netflix or YouTube 4K | 7 to 16 GB | Extreme |

Read the category column and a clean three tier picture emerges. The essentials of travel, maps, messaging, browsing and music, all sit in the light tiers, costing tens of megabytes at most. Social feeds sit in the middle. And video, whether streamed directly or embedded in social Reels, occupies every heavy tier. The gap between a light activity and video is not a few times larger, it is hundreds of times larger.

## Why is video so much heavier than everything else?

Video dominates because it is the only common activity that streams a continuous, high resolution moving image in real time. Text is a few bytes per character. A photo is a few megabytes once. Audio is a modest, steady trickle. But video sends dozens of full frames every second, and the higher the resolution, the more data each of those frames carries.

That is why the same app can cost wildly different amounts depending on quality. YouTube at 480p might use 500 to 700 MB an hour, while the same hour at 4K can hit 10 to 16 GB, more than twenty times as much for content you may not even notice looks sharper on a small phone screen. Netflix follows the same curve: roughly 300 MB per hour on its data saving setting versus up to 7 GB per hour in 4K. Because the multiplier is so steep, the single most powerful data saving move for any traveller is capping video quality. Dropping from HD to 480p on a phone is nearly invisible to the eye and can cut data use to a third or less.

The other lesson is that streamed video and downloaded video are completely different costs. Streaming an episode over your mobile plan spends data every time you watch. Downloading the same episode over Wi-Fi before you travel spends it once, on a free connection, and costs nothing on the trip. This is why seasoned travellers download shows, films and playlists the night before, and treat live streaming abroad as a last resort. Our [guide to saving mobile data while traveling](/magazine/how-to-save-mobile-data-while-traveling/) has the full set of quality caps and download habits.

## How much data do maps and messaging really use?

The good news for travellers is that the things you rely on most abroad are also the cheapest. Turn by turn navigation on Google Maps or Apple Maps uses only about 3 to 5 MB per hour in standard view, rising to 7 to 10 MB with live traffic. Even a full day of driving costs less data than a few minutes of video. And if you download an offline map before you leave, a one time cost of roughly 100 MB per city, navigation runs on your phone GPS and uses essentially no mobile data at all.

Messaging is similarly negligible. WhatsApp, iMessage, Telegram and Signal all cost a few megabytes across hours of texting and sharing photos. WhatsApp voice calls are cheap too, at roughly 0.5 to 1 MB per minute, so a half hour call home is around 15 to 30 MB. The one messaging activity to watch is video calling, which jumps to 5 to 15 MB per minute, or 200 to 300 MB an hour, so it belongs with the heavy tier rather than the light one.

Web browsing and email land in the light tier at 30 to 60 MB per hour, with image heavy sites at the top of that range and plain text well below it. Reading news, checking bookings, translating a menu and searching for a restaurant all fall here, and none of them threatens a data plan. The practical conclusion is reassuring: everything a traveller genuinely needs to get around and stay in touch is inexpensive. It is only the optional entertainment that gets costly. For definitions of the underlying terms, our [data roaming glossary entry](/glossary/data-roaming/) and [eSIM glossary entry](/glossary/esim/) explain how the data actually reaches your phone.

## How much data does social media use?

Social apps sit in an awkward middle ground, and the reason is video. A decade ago social feeds were mostly text and photos and cost very little. Today they are dominated by autoplaying video, which pushes their data use up sharply.

Scrolling a standard Instagram or Facebook feed uses roughly 120 to 220 MB per hour, moderate but manageable. The moment you switch to Reels or short video, though, consumption climbs to 600 MB to 1 GB per hour, because you are now watching continuous video. TikTok is essentially all short video and uses around 840 MB per hour in its default setting, dropping to roughly 360 MB per hour with Data Saver enabled. So an hour of Reels or TikTok can quietly match an hour of streaming a show.

The two levers that tame social data are autoplay and quality. Turning off autoplay video stops feeds pre loading clips you never chose to watch, and enabling each app Data Saver mode lowers the resolution of what does play. With both on, a social habit that might have cost a gigabyte an hour can drop by half or more. For travellers on a fixed plan, this is often the difference between the plan lasting the whole trip and running dry early. If you upload as well as watch, our [guide to uploading travel photography on the go](/magazine/travel-photography-uploading-on-the-go/) covers keeping posts and backups affordable.

## How do I turn these numbers into a plan size?

The per app numbers become a plan size when you multiply your realistic daily hours by the figures above, then add the essentials for free. A useful shortcut is to ignore the light tier entirely, because maps, messaging and browsing barely move the needle, and budget almost entirely for your video, social and video calling hours.

Take a typical medium day: forty minutes of navigation, constant messaging, an hour of browsing, an hour of social feeds with autoplay off, some music on the move, and a short video call home. Almost all of that daily total comes from the social hour and the video call; the rest rounds to near zero. That is why a realistic medium user lands around 1 GB per day, and why cutting one hour of HD streaming saves more than optimising everything else put together. Our [how much data do I need for travel guide](/magazine/how-much-data-do-i-need-for-travel/) turns this into ready made light, medium and heavy profiles with weekly totals.

Once you know your daily figure, add a buffer and buy a prepaid plan that covers it, rather than gambling on your home carrier roaming rates. Prepaid travel eSIM plans from [Viasimo](/) install by QR in minutes with instant email delivery, so if your apps run hungrier than planned you simply buy another plan on the spot, with no overage billing and no bill waiting at home. Browse the [destinations page](/destinations/) for live plan sizes and prices for [Spain](/destinations/spain/), [Japan](/destinations/japan/) and your route, match the tier to your heaviest apps, and spend the trip watching, calling and posting without rationing.
