You have a 3 GB travel plan and a Reels habit, so you want to know what the app is actually costing you. Here is the short version. Continuous Reels is the heaviest thing Instagram does, at roughly 600 megabytes (MB) to 1.5 gigabytes (GB) an hour. Ordinary feed scrolling with video autoplaying sits nearer 300 MB to 700 MB an hour. Stories land a little below the feed. Video calls are lighter than most people expect, voice calls are trivial and text messages barely register at all.
Those spreads are wide for a reason. Instagram picks a video quality to match your connection, so a fast 5G signal makes the same 10 minutes of Reels cost noticeably more than a weak signal does. Screen size, autoplay behaviour and how much the app preloads while you scroll all push the number around too.
What follows is a breakdown by feature, an honest note on where these ranges come from, the settings that cut usage on iPhone and on Android and a method for turning your habits into a plan size.
How much data does Instagram use
Treat the table below as a planning tool rather than a promise. It reflects typical usage on a modern handset over a good connection, with the app on default quality settings.
| What you are doing | Indicative use per hour | Roughly per minute |
|---|---|---|
| Scrolling the feed with video autoplay | 300 MB to 700 MB | 5 MB to 12 MB |
| Watching Reels back to back | 600 MB to 1.5 GB | 10 MB to 25 MB |
| Watching Stories | 250 MB to 600 MB | 4 MB to 10 MB |
| Instagram video call | 200 MB to 500 MB | 3 MB to 8 MB |
| Instagram voice call | 25 MB to 60 MB | under 1 MB |
| Direct messages, text and photos | 10 MB to 40 MB | under 1 MB |
| Any of the above with Data Saver on | 100 MB to 350 MB | 2 MB to 6 MB |
Where these ranges come from
Instagram does not publish a data cost per hour, and no honest article can give you a single exact figure. Video is variable by design. The app requests a stream that suits the bandwidth it detects, so identical viewing sessions on different networks produce different totals.
The way to get numbers you can trust is to measure your own. Both mobile operating systems keep a per-app counter you can reset before a test session, so 20 minutes of scrolling gives you a figure worth more than any average. Instagram’s own guidance on media quality and mobile data lives in the Instagram Help Centre, and it is the right place to check what a toggle currently does.
3 variables account for most of the difference between a light session and a heavy one.
- Connection speed, because a faster link invites a higher video quality.
- Preloading, since the app fetches upcoming clips before you reach them.
- How long each clip holds you, as rewatching a Reel usually plays from cache rather than the network.
Reels are the heaviest feature
Reels combines everything expensive in one place: full-screen video, high frame rates, sound and an interface built to keep you scrolling. Each clip is short, so the app preloads the next several to make swiping feel instant. That preloading is what quietly drains an allowance when you only meant to look for 5 minutes.
A useful mental model is that 1 GB buys somewhere between 40 and 100 minutes of Reels at default quality. Turn Data Saver on and the same 1 GB can stretch to 3 hours or more, at the cost of softer video and a slight pause when a clip has not preloaded. On a metered travel plan that trade is usually worth making.
Live video sits in the same weight class as Reels, and a long broadcast at full quality moves through an allowance just as fast.
Feed, Stories and direct messages
Scrolling the feed
A photo-heavy feed is cheap. Individual images arrive compressed, often at a few hundred kilobytes each, so half an hour of pure photo browsing might cost less than a single minute of Reels. The moment video enters the feed and starts playing automatically, the cost climbs towards the Reels figure. Most feeds are a mix, which is why the table’s range is broad.
Watching Stories
Stories are short, vertical and mostly video, so they behave like a lighter version of Reels. They are usually encoded at a lower bitrate than a polished Reel, and many are static images that cost almost nothing. Tapping through quickly can actually raise usage, because the app keeps fetching the next Story in each tray while you skip.
Direct messages and voice notes
Text conversations are effectively free at travel-plan scale. Photos sent in a chat cost a few hundred kilobytes each, voice notes cost a fraction of a megabyte per minute and a short video clip is the only thing in messaging that registers meaningfully. If your trip is mostly about staying in touch rather than browsing, Instagram will not be the app that empties your plan.
Video and voice calls compared
Instagram video calls cost less than most people assume. A call is a 2-way stream at a modest resolution, and the app drops quality quickly when the connection wobbles, which keeps the total down. Expect a video call to sit in the same territory as watching Stories rather than watching Reels.
Voice calls are cheaper again by a wide margin. A voice-only call runs at a low bitrate and can carry on for an hour for the price of a couple of minutes of Reels. When you are counting every megabyte in a foreign country, switching a video call to voice is the single most effective change you can make in the app.
Group video calls are the exception. Each additional participant adds another incoming stream, so a 4-person call can cost several times a 1-to-1 call over the same period.
Posting costs data as well
Uploading is easy to forget because it happens in the background. A single photo post typically costs a few megabytes. A 30-second Reel filmed on a modern phone usually lands between 15 MB and 50 MB depending on resolution, and a batch of Story clips at the end of a long day can add up faster than an evening of watching.
Instagram also offers a setting that uploads posts at the highest quality it supports. Results look better on other people’s screens, but every upload grows. Leave it off on a metered plan and switch it back on over hotel Wi-Fi.
Cutting usage inside the app
Open your profile, tap the menu icon with 3 lines in the top corner, then tap “Settings and activity”. Look for “Data usage and media quality”. Current builds show a “Data Saver” toggle there and older builds label the same control “Use less mobile data”. Beneath it you will usually find a media quality choice and an “Upload at highest quality” switch.
Turning Data Saver on stops the app preloading video, which is where most of the saving comes from. Videos still play at full length, they simply load when you reach them rather than in advance. Expect these controls to move after an update, since Instagram reorganises its settings menu regularly.
Settings that help on iPhone
Open Settings, then tap “Mobile Data”, which is labelled “Cellular” in the United States. Scroll down to the app list and you will see how much each app has used since the counter was last reset, with Instagram usually near the top. Tapping “Reset Statistics” at the bottom of that screen before a test session gives you a clean measurement.
For a firmer limit, go to Settings, “Mobile Data”, “Mobile Data Options”, then “Data Mode” and choose “Low Data Mode”. That setting pauses automatic updates and background tasks across the whole phone, and it noticeably reduces how aggressively apps preload video. Apple explains the behaviour of these controls on its support site. For a hard stop, switch the Instagram toggle off in that list and the app will work on Wi-Fi only.
Settings that help on Android
Menu names differ by manufacturer, so use your own device’s wording. On a Google Pixel, open Settings, tap “Network and internet”, then “Data Saver” for a system-wide restriction on background traffic. On a Samsung Galaxy, open Settings, tap “Connections”, tap “Data usage”, then “Mobile data usage” to see per-app totals. Tap Instagram there to restrict its background data.
Android also lets you set a warning and a hard cap. Inside the mobile data settings you will find “Data warning and limit”, where you can set a monthly ceiling and have the phone cut mobile data when it is reached. That is a useful safety net on a trip, because it stops a single evening of scrolling from consuming an allowance you needed for maps.
Turning your habits into a plan size
Work from minutes rather than guesswork. Estimate the video minutes you watch on a normal day, multiply by 15 MB as a mid-range figure, then add a flat 300 MB a day for maps, messaging, email and browsing. A traveller who watches 30 minutes of Reels daily lands near 750 MB a day, so a 10-day trip needs somewhere close to 8 GB with a little headroom.
Halve the video figure if you keep Data Saver on, and double it if you post Stories every evening. The Qrispy data usage calculator does this arithmetic for you across all your apps, and it is a faster route to a number than any published average. Our wider guide to sizing a trip covers the non-video apps in more depth.
Once you have a figure, the shape of your embedded SIM (eSIM) plan matters as much as the size. A Qrispy Fixed Plan suits a trip where your usage is predictable, with durations of 3, 7, 15 or 30 days and a stated allowance. The Global Wallet suits unpredictable trips, because you top up a balance, spend it across 210+ countries and regions and the credits never expire. Unlimited Data Plans, available in 90+ countries for 3, 7, 15 or 30 days, suit heavy viewers who would rather not count at all, with the caveat that fair use or temporary speed management may apply during very heavy usage or congestion. Compare all 3 on the Qrispy eSIM plans page.
Frequently asked questions
How many hours of Reels per GB?
At default quality, 1 GB buys roughly 40 to 100 minutes of continuous Reels, so most people get somewhere between 1 and 2 hours. Switching Data Saver on stops the app preloading clips in advance and can stretch the same 1 GB past 3 hours. Your exact figure depends on connection speed and video quality.
Does Data Saver really cut Instagram data?
Yes, and the saving is significant. The setting stops Instagram fetching upcoming videos before you scroll to them, which is where a large share of usage disappears on a normal session. Video still plays, it just loads on demand. Expect roughly half the usage of a default session, with a short wait when a clip has not loaded.
Do Instagram calls use much data?
Less than watching video. A 1-to-1 video call typically costs around the same as watching Stories for the same length of time, because the app sends a modest resolution and drops it further on a weak link. Voice calls are far cheaper again. Group video calls are the expensive case, since every extra participant adds another stream.
Does posting use more data than watching?
Not usually, unless you post a lot of video. A photo costs a few megabytes to upload and a 30-second Reel typically costs between 15 MB and 50 MB. An hour of watching Reels still costs more than a normal day of posting. Turning off the highest quality upload option keeps posting costs down on a metered plan.
Should I use Low Data Mode abroad?
It is worth switching on if your plan has a fixed allowance. Low Data Mode holds back background refreshes and automatic downloads across the whole iPhone, not just Instagram, so it protects your allowance from apps you are not actively using. Turn it off when you reach Wi-Fi if you want photo backups and updates to catch up.
Does Instagram use more data than TikTok?
The 2 apps sit in the same range, because both stream full-screen short video with aggressive preloading. Which one costs more on your phone depends on the quality settings each app has chosen and how long you spend in each. Measure both with your operating system’s per-app counter rather than trusting a general comparison.
