How can I use less data while travelling?
Download offline maps and playlists while on Wi-Fi, turn off autoplay video in social apps, disable automatic photo backup, and switch on the system data saver. Those four typically cut usage by more than half.
Download offline maps and playlists while on Wi-Fi, turn off autoplay video in social apps, disable automatic photo backup, and switch on the system data saver. Those four typically cut usage by more than half. This page goes through each one in more depth than the short answer, along with how to track down where data is going if it still runs out faster than expected, and how to work out how much to buy in advance.
It suits anyone worried a data allowance will not last the whole trip, anyone who has used it up faster than expected on a previous trip, and anyone who wants to get the phone set up to save data before even leaving the accommodation on day one. The focus is on settings you can actually change on the phone, rather than general usage figures or statistics.
Why data runs out faster than expected while travelling
During a trip, navigation apps often stay open all day, social apps get opened more often to share the experience, and photos naturally get taken more frequently. Combined, these activities push daily data usage noticeably higher than at home, even though each individual app's own behaviour has barely changed.
Another cause that often gets overlooked is background activity you are not actively aware of, such as email syncing, automatic app updates, or photo backup to the cloud, all of which consume data continuously even when that app is not open at all, pushing total usage higher than it feels like from active use alone.
Download offline maps before leaving your accommodation
Most map apps support downloading an area in advance for offline use. Do this while still connected to Wi-Fi at the accommodation or airport, rather than letting the app reload fresh map data over mobile data every time navigation is opened, which is one of the most continuously data-hungry activities during the day.
Offline navigation carries an added benefit of still working even in areas with weak or briefly dropped signal, meaning you do not need a continuous mobile connection throughout each day's movement around.
Download playlists and podcasts in advance
Music, podcasts, and shows watched while travelling can nearly all be downloaded in advance in apps that support an offline mode. Download them the night before, while still at the accommodation, or while connected to airport Wi-Fi, rather than streaming live over mobile data for the whole trip.
Continuous live streaming is one of the most data-hungry activities per hour, unlike a file already downloaded, which can be played or watched again as many times as you like without using any further data at all after that first download.
Turn off autoplay video in social apps
Most social apps are set to autoplay video the instant it scrolls into view in the feed, even without any intention to watch it. Go into each app's own settings to turn this off, usually found in a menu related to data usage or media.
Turning off autoplay does not stop you from watching videos at all — it simply requires a tap to play instead of playing the instant it scrolls into view, which meaningfully cuts the data spent on videos you never actually meant to watch.
Disable automatic photo backup
Automatic cloud photo backup is often set to trigger the moment a photo is taken, especially high-resolution photos and videos that take up an unusually large amount of space during a trip. Turn it off temporarily in the settings of whichever photo app or cloud service you use, then switch it back on to catch up all at once once back on Wi-Fi.
Turning off automatic backup temporarily does not make any photos already taken disappear. Every photo stays on the device exactly as normal — it simply has not been uploaded to the cloud yet until backup is switched back on or Wi-Fi is available.
Switch on the system's data saver mode
Both iOS and Android have a system-wide data saver mode that limits background data use across every app at once, rather than needing to configure each app individually. Leaving this switched on for the whole trip meaningfully cuts invisible usage without directly affecting the app you have open in front of you at that moment.
The menu for this sits in a slightly different place between iOS and Android, and can vary further by operating system version. If you cannot find it in the settings screen you expect, try searching 'data saver' or 'low data mode' in the settings app's own search box.
Checking which apps use data in the background without you noticing
The system's own data usage settings usually list apps ranked by how much they have used over a recent period. Take a look at this list once on the first day at the destination, to see which app is using far more than expected without you deliberately opening it that often.
If you spot an app using unusually high data without you having actively opened it, check that specific app's own auto-sync or background update setting, rather than turning off the whole line's data roaming, which affects every app at once.
Sharing a hotspot economically
If sharing a hotspot with other devices in the group, all the data comes from the one shared pool on the sharing line, not a separate quota for each device that connects. Turning on data saver mode on the receiving devices too still helps cut the combined total usage.
Agree with the group in advance on what each person should do before connecting to the hotspot, such as downloading their own maps and playlists ahead of time too, rather than relying solely on the hotspot connection for the whole trip.
Supplementing with public Wi-Fi carefully
Many accommodations, cafés, and attractions offer free Wi-Fi. Connecting to it whenever available takes a good deal of load off mobile data, especially for heavier activities such as updating apps or downloading large files.
One thing to watch is that some public Wi-Fi spots can be unstable or slower than expected. Use it as a supplement for non-urgent activities, rather than relying on it as the main connection for anything that needs stability while actually moving around, such as real-time navigation.
Estimating the data allowance you will actually need
Instead of guessing how much data to buy, use the data calculator tool on the site. Enter the number of travel days and a rough sense of your usage habits, such as how often navigation is used or how often you post on social apps, to get a figure closer to your actual need than picking a plan by feel.
Estimating ahead of time like this reduces both the risk of buying too little and needing to top up mid-trip, and the risk of buying too much and spending unnecessarily, since usage habits genuinely differ between people — there is no single figure that fits everyone.
If data is running low mid-trip
If data turns out to be running low before the trip ends, apply the four changes on this page more strictly first, especially turning off autoplay video and photo backup, which are usually the biggest invisible drains. If that still is not enough, consider buying a top-up or a new plan through your destination's plan page.
Always check the terms of the top-up option before confirming, since some options extend the existing plan's dates, while others arrive as a fresh data block with their own separate expiry.
The four changes that cut usage the most
| Setting | Why it has a big impact |
|---|---|
| Download maps and playlists offline in advance | Removes repeated reloading over mobile data every time it is opened, which happens most often during the day |
| Turn off autoplay video in social apps | Stops data being spent on video you never actually meant to watch while scrolling the feed |
| Disable automatic photo backup | Cuts continuous uploading of large files, especially high-resolution photos and video |
| Switch on the system's data saver mode | Limits background data across every app at once without configuring each one individually |
Common symptoms and how to handle them
| Symptom | Likely cause | What to do |
|---|---|---|
| Data ran out faster than expected from day one | Maps or playlists were not downloaded offline before leaving the accommodation | Download offline whenever Wi-Fi is available, and switch on the system data saver right away |
| One app is using unusually high data without being actively opened | That app's own auto-sync or backup setting is still switched on | Check the system's data usage settings and turn off only that app's auto-sync |
| Sharing a hotspot used data up faster than calculated | The calculation only covered the main device, not the others connecting to it | Recalculate using the data calculator, counting every device that will connect through the hotspot |
| Every step has been applied but data is still nearly gone before the trip ends | Actual usage is simply higher than the allowance bought | Consider a top-up or a new plan through your destination's plan page |
- Download maps and playlists offline before leaving the accommodation each day
- Turn off autoplay video in every social app you use regularly
- Disable automatic photo backup temporarily and turn it back on when back on Wi-Fi
- Keep the system's data saver mode switched on for the whole trip
- Use the data calculator to estimate how much to buy in advance
FAQ
Does the system's data saver mode block important apps?+
It generally does not block the app you have open in front of you, but it does limit background activity for apps that are not open. If a particular app genuinely needs to update continuously, check the data saver menu for a setting to exempt that specific app.
If automatic photo backup is turned off, do already-taken photos disappear?+
No. Every photo stays on the device exactly as normal — it simply has not been uploaded to the cloud yet, until backup is switched on again or Wi-Fi becomes available.
How much data should be bought in advance?+
Use the data calculator on the site, entering the number of days and a rough sense of usage habits, to get a figure close to your actual need, rather than guessing from a generic number.
How much data does sharing a hotspot with a friend use up?+
It depends entirely on what your friend does through that hotspot — streaming video uses far more than messaging. Agree in advance on what each person should download offline before connecting.
Is public Wi-Fi reliable enough to replace mobile data entirely?+
The quality and stability of public Wi-Fi varies enormously from one spot to another. It works well as a supplement for non-urgent activities, but should not be relied on as the main connection for anything needing stability while actually moving around, such as real-time navigation.
What should be done if data runs out before the trip ends?+
Check whether the four main data-saving changes have all been applied. If they have and it is still not enough, buy a top-up or a new plan through your destination's plan page, and always check the top-up option's terms before confirming.
