How much data do I need for a one- or two-week trip?

Most travellers use far less data than they fear on some days and far more on others. This guide gives approximate figures for common apps, worked examples for one and two weeks, and simple ways to stay within your plan.

The short answer

For a one-week trip, a light user who mostly relies on maps, messaging and browsing, with Wi-Fi at the hotel, typically needs somewhere in the region of 2 to 5 GB. A moderate user who also posts photos and makes the odd video call often needs roughly 5 to 10 GB. For two weeks, roughly double those figures.

Heavy users, people working remotely, anyone streaming video on mobile data or sharing a hotspot with others can easily need much more, sometimes several gigabytes a day. For them an unlimited plan charged by the day is often simpler than guessing.

These numbers are deliberately approximate. Actual usage varies with apps, settings, video quality and how much Wi-Fi you have. The rest of this guide shows where the figures come from so you can adjust them to your own habits.

How much data common apps use

The table below is a rough guide based on typical settings. Treat every figure as an approximate range rather than a precise measurement: apps change, and the same activity can use very different amounts depending on quality settings.

  • Messaging (WhatsApp, iMessage, Signal), text only: very little, often a few megabytes a day.
  • Sending photos in chats: roughly 0.1 to 1 MB per photo, depending on compression.
  • Voice calls over apps: roughly 0.5 to 1 MB per minute.
  • Video calls: roughly 0.5 to 1.5 GB per hour, more in high quality.
  • Maps and navigation: often around 5 to 20 MB per hour of active navigation, less with offline maps.
  • Web browsing and email: roughly 50 to 150 MB per hour of active use, more on media-heavy sites.
  • Social media with video (Instagram, TikTok and similar): roughly 0.5 to 1.5 GB per hour of scrolling.
  • Music streaming: roughly 40 to 150 MB per hour depending on quality.
  • Video streaming: roughly 0.5 to 1 GB per hour in standard definition, often 2 to 3 GB per hour or more in HD.
  • Uploading photos to cloud backup: a few megabytes per photo; videos can be hundreds of megabytes each.

The things that surprise people

Maps and messaging, the apps travellers worry about most, use surprisingly little. The big consumers are video in all its forms: streaming, video calls, autoplaying clips in social feeds, and automatic backup of the videos you shoot. A single evening of streaming on mobile data can use more than a week of navigation.

Daily usage by type of traveller

Most people fit roughly into one of three patterns. Find the one closest to you, then multiply by the number of days you will rely on mobile data.

Light user: roughly 200 to 500 MB a day

You use maps to get around, message friends and family, check opening times and book the occasional ticket. You upload photos on hotel Wi-Fi in the evening and do not stream on the go.

Moderate user: roughly 0.5 to 1.5 GB a day

As above, plus regular social media browsing, sharing photos and short videos during the day, a short video call home and some music streaming on transport.

Heavy user: roughly 2 GB a day or more

You stream video, make long video calls, work remotely, back up photos and videos automatically or share your connection with a laptop or other people. Usage at this level can vary a lot from day to day, which is why unlimited plans are popular with this group.

Worked examples for a one-week trip

These examples assume hotel or apartment Wi-Fi in the evenings. Without it, add your evening usage to the total.

  • City break, light use: 7 days of maps, messaging and browsing at around 300 MB a day comes to roughly 2 GB. A small fixed data plan with a little headroom is usually enough.
  • Beach holiday with social media: around 1 GB a day for scrolling, sharing and the odd call adds up to roughly 7 GB.
  • Road trip with navigation and music: navigation is light, but streaming music for several hours a day can add 0.3 to 0.5 GB daily on top. Expect roughly 4 to 8 GB, less if you download playlists in advance.
  • Working week abroad: two or three hours of video calls a day on mobile data alone can use 2 to 4 GB a day. An unlimited plan or a large fixed plan is the safer choice.

Worked examples for a two-week trip

Two weeks is not always exactly double one week. Many people use more data in the first few days, while working out routes and booking things, then settle into a routine.

  • Two weeks of light use: roughly 3 to 7 GB.
  • Two weeks of moderate use: roughly 7 to 20 GB.
  • Two weeks across several countries by train: add some margin for travel days, when you are checking connections, tickets and accommodation on the move without Wi-Fi. Roughly 8 to 15 GB is common for moderate users. Our Interrail guide has more on this.
  • Two weeks of remote work: often 30 GB or more if you rely on mobile data rather than Wi-Fi. Consider unlimited.

Hidden data use to watch for

Some of the biggest drains on a travel data plan happen in the background, without you opening an app.

  • Photo and video backup to iCloud, Google Photos or similar. Set it to Wi-Fi only.
  • App and system updates. Most phones wait for Wi-Fi by default, but check.
  • Autoplay video in social and news apps. Most apps have a setting to disable autoplay on mobile data.
  • Podcasts and playlists that download new episodes automatically.
  • Laptops on your hotspot. A laptop connected to your phone may treat the connection as normal Wi-Fi and start large downloads. Pause sync and updates first.
  • Messaging app media. Group chats with lots of videos can download them automatically. Change media auto-download to Wi-Fi only.

Practical ways to make your data last

None of these require you to give up anything important. They just move heavy tasks to Wi-Fi.

  • Download offline maps for the cities and regions you are visiting before you travel. Google Maps and several other map apps support this.
  • Download playlists, podcasts and films at home or at the hotel.
  • Use your phone's data saver mode. On iPhone it is called Low Data Mode; on Android it is usually called Data Saver.
  • Lower video quality in streaming apps when you are on mobile data.
  • Turn off automatic backup on mobile data and let it catch up on Wi-Fi.
  • Check usage per app in your phone's mobile data settings after the first day to see where it is going.

Turning your estimate into a plan

Once you have a rough number, add a margin of around 20 to 30 per cent. Travel days, unexpected changes of plan and a hotel with poor Wi-Fi can all push usage up.

When to choose fixed data

If your estimate is reasonably confident and you are a light or moderate user, a fixed data plan is usually the most economical. If you run low, you can add more data to the same eSIM without reinstalling anything.

When to choose unlimited

If your usage is unpredictable, heavy or shared, an unlimited plan charged by the day removes the guesswork. Bear in mind that speed may slow after heavy use, so unlimited is about not running out rather than guaranteed full speed all day.

When to choose no-expiry

If you take several short trips to the same region, a no-expiry plan lets you buy a larger amount once and use it across trips, without worrying about leftover data expiring.

Start smaller if unsure

Because top-ups are easy, it is often sensible to start with a plan near your estimate rather than far above it, then check how much data is left after a couple of days. Current plan sizes and prices for each destination are on the prices page.

Sharing data with family or friends

If one phone acts as a hotspot for several people, add each person's usage together. Two moderate users sharing one connection can easily use 2 to 3 GB a day between them, and children watching video can use more. For groups, it is often simpler for each adult to have their own eSIM, or for the hotspot phone to use an unlimited plan.

Frequently asked questions

Is 1 GB enough for a week?

For a very light user who has Wi-Fi every evening and uses offline maps, it can be. For most people it is tight. Something in the region of 2 to 5 GB gives more comfortable headroom for a week of maps, messaging and browsing.

Is 10 GB enough for two weeks?

For most light and moderate users, roughly 10 GB covers two weeks if heavy tasks such as backups and streaming are kept to Wi-Fi. If you stream video, make long video calls or share a hotspot, it may not be.

Do maps use a lot of data?

Usually not. Active navigation tends to use tens of megabytes per hour at most, and offline maps reduce that further. Satellite view and street-level imagery use more.

How can I see how much data I have used so far?

Your phone shows usage per line in its mobile data settings, and you can also check your remaining Spidot balance using our guide on how much data is left.

What happens if I run out of data?

On a fixed data plan, data stops working once the allowance is used up. You can add more data to the same eSIM, so it is worth keeping an eye on your balance on busy days.
