How much data do I need for travel? Daily usage, trip totals and app by app
How much data do you need for travel? Daily usage for light, typical and heavy users, trip totals for 1 week to 1 month, data use per app and tips to use less.
Most travellers need between 0.5 and 1.5 GB of mobile data per day, as long as they have Wi-Fi at the hotel. That means 5 to 10 GB covers a typical week and 10 to 20 GB a typical fortnight. Streaming video, video calls or sharing your connection with a laptop push the figure to 2–3 GB a day or more, and that is where unlimited plans start to make sense. This guide shows where the data goes app by app, how to estimate your own trip, and how to use less without missing anything.
The short answer: data per day and per trip
Find the row that matches how you use your phone away from Wi-Fi, then read across to your trip length. The totals already include a small buffer.
| How you use your phone | Per day | 1 week | 2 weeks | 1 month |
|---|---|---|---|---|
| Light: maps, messaging, email, booking apps | 0.3–0.5 GB | 3–5 GB | 5–7 GB | 10–15 GB |
| Typical: plus social media, photo sharing, music | 0.8–1.5 GB | 6–10 GB | 12–20 GB | 25–45 GB or unlimited |
| Heavy: video, video calls, laptop hotspot | 2–3 GB or more | 15–20 GB or unlimited | Unlimited | Unlimited |
Two things move you between rows more than anything else: video (watching, uploading or calling) and hotspot use, because a laptop downloads updates and syncs files in the background. If neither applies, you are almost certainly a light or typical user.
How much data common apps use
These are rough figures from typical settings. Actual use depends on the app version, the quality setting and how much video is in your feed.
| Activity | Approximate data use |
|---|---|
| Navigation in Google Maps or Apple Maps | 5–20 MB per hour; far less with offline maps |
| Text messages in WhatsApp, iMessage, LINE | A few MB per day; photos in chats about 0.1–0.5 MB each |
| Voice calls over the internet | About 0.5–1 MB per minute (30–60 MB per hour) |
| Video calls | About 5–15 MB per minute (0.3–0.9 GB per hour), more in HD |
| Social media with video (Instagram, TikTok) | Roughly 300–800 MB per hour of scrolling |
| Music streaming | About 40–150 MB per hour, depending on quality |
| Video streaming | About 0.5–1 GB per hour in SD, 1.5–3 GB per hour in HD |
| Web browsing | About 1–3 MB per page |
| Photo backup in full quality | 2–5 MB per photo; video 60–130 MB per minute in 1080p, 170–400 MB in 4K |
| App and system updates | Hundreds of MB to several GB; keep them for Wi-Fi |
The pattern is clear: maps, messaging and calls are cheap; anything with video is expensive. One hour of HD streaming uses as much data as several days of navigation and chatting. Short videos in social feeds are the most common surprise, because they play automatically and nobody counts them as “watching video”.
Three example travel days
A sightseeing day in a city
Three hours of navigation (about 30–60 MB), messaging with a few dozen photos (about 20–50 MB), two short internet calls home (about 10–20 MB), half an hour of social media with video (about 150–400 MB) and some browsing for restaurants and tickets (about 40–60 MB). Total: roughly 0.3–0.6 GB.
A beach or travel day
Little navigation, a long bus or train ride with an hour of music streaming (about 40–150 MB) and an hour of social media (about 300–800 MB), plus messaging. Total: roughly 0.5–1 GB. Download playlists and podcasts beforehand and this drops to a fraction.
A working day with a laptop on hotspot
Email and documents (about 100–300 MB), one hour of video calls (about 0.3–0.9 GB), plus whatever the laptop syncs in the background (cloud folders, updates, browser tabs). Total: easily 1.5–3 GB or more. For several days like this, look at unlimited plans or large data packages.
Data needs by type of trip
The kind of trip often predicts data use better than the number of days:
- City break: lots of navigation and searching for places, but hotel Wi-Fi in the evening. Light to typical use; 3–5 GB for a long weekend is plenty.
- Beach or resort holiday: Wi-Fi at the pool and in the room is common, so mobile data is mainly for excursions. Light use; a small plan with long validity is usually enough.
- Road trip: navigation for hours every day, music in the car and searching for places to stop. Download offline maps and playlists, then plan for typical use; without them, use climbs quickly.
- Backpacking through several countries: hostels have Wi-Fi of varying quality, and buses and trains are long. Typical use, and a regional plan that covers every country on the route saves buying several eSIMs.
- Business trip: email, documents and video calls between meetings, often with a laptop on hotspot. Heavy use; choose unlimited or a large package.
- Family trip: if parents share their connection with children's tablets for videos, a single phone becomes a heavy user. Separate eSIMs for each adult phone, or one unlimited plan with a generous daily allowance, avoid surprises.
Also think about the Wi-Fi you can count on. Reliable Wi-Fi at the accommodation moves you down a row in the table above; working from cafés with weak Wi-Fi moves you up.
Fixed data or unlimited?
A fixed-data plan is cheaper as long as you stay under about 1.5 GB per day on average. Above that, or when you would rather not count at all, unlimited plans become the better deal.
Check one detail before you buy unlimited: almost every “unlimited” travel plan has a daily full-speed allowance, typically 1 to 3 GB, after which the speed drops until the next day. At 128 kbps only messaging works properly; at 1 Mbps maps, social media and music remain usable. If you need unlimited for video or work, choose a plan with at least 2 GB per day at full speed. Our destination guides for Japan and Thailand compare these limits with live prices.
What these amounts cost
Prices depend heavily on the destination. As an example, here are today's cheapest plans for each data amount on our Europe comparison, among plans valid for at least a week:
| Data | Validity | Price | Per GB | Provider | |
|---|---|---|---|---|---|
| 1 GB regional plan, 2 countries | 7 days | $0.61 (€0.55) | €0.55 | eSIM.dog | View plan |
| 2 GB regional plan, 2 countries | 7 days | $1.03 (€0.92) | €0.46 | eSIM.dog | View plan |
| 3 GB regional plan, 2 countries | 7 days | $1.03 (€0.92) | €0.31 | eSIM.dog | View plan |
| 5 GB regional plan, 2 countries | 7 days | $1.65 (€1.48) | €0.30 | eSIM.dog | View plan |
| 10 GB regional plan, 33 countries | 7 days | $3.84 (€3.44) | €0.34 | eSIM.dog | View plan |
| 20 GB regional plan, 28 countries | 30 days | $6.13 (€5.49) | €0.27 | eSIM.dog | View plan |
| 50 GB regional plan, 33 countries | 7 days | $15.94 (€14.27) | €0.29 | eSIM.dog | View plan |
The Europe plans in this table are regional plans covering many countries, which is why the price per GB is a fair comparison even if you only visit one or two of them.

How to use less data abroad
- Download offline maps of every city and region you visit, in Google Maps or Apple Maps, before you leave.
- Turn on Low Data Mode (iPhone) or Data Saver (Android) for the travel line. Background refresh and automatic downloads pause.
- Set photo and video backup to Wi-Fi only in iCloud, Google Photos or your cloud app.
- Lower streaming quality in Netflix, YouTube and Spotify, or download episodes and playlists in advance.
- Turn off video autoplay in Instagram, Facebook and other social apps.
- Keep app and system updates for Wi-Fi.
- On a laptop hotspot, mark the connection as metered (Windows) or pause cloud sync, so updates and file sync do not run over your eSIM.
How to check how much data you have used
Before you leave, reset the usage statistics so the counter only shows your trip:
- iPhone: Settings → Cellular (Mobile Data). Usage is listed per line and per app; “Reset Statistics” is at the bottom of the page.
- Android: Settings → Network & internet → SIMs → your travel SIM → App data usage (Pixel), or Settings → Connections → Data usage (Samsung).
- The provider's app or account page shows the remaining data on the plan itself, which is the number that counts.
Check after the first day or two. If you are well above your estimate, you still have time to switch settings or buy a top-up before the data runs out. If your eSIM stops working altogether, our guide eSIM not working abroad? 10 fixes walks through the usual causes.
Questions travellers ask
Is 1 GB per day enough for travel?+
For most travellers, yes. Maps, messaging, calls, browsing and some social media fit comfortably into 1 GB a day. Regular video streaming, long video calls or using your phone as a hotspot for a laptop can exceed it.
How much data do I need for a 2-week trip?+
Light users need about 5 to 7 GB, typical users about 12 to 20 GB. If you stream video or work on a laptop over the phone's connection, an unlimited plan with at least 2 GB per day at full speed is usually the better choice.
How much data does Google Maps use?+
Navigation typically uses about 5 to 20 MB per hour. With offline maps downloaded beforehand it uses much less, because the map itself no longer has to load over mobile data.
Does WhatsApp use a lot of data?+
Text messages use very little. A voice call uses roughly 0.5 to 1 MB per minute and a video call about 5 to 15 MB per minute. Automatic media downloads add up, so set them to Wi-Fi only while travelling.
Should I buy an unlimited eSIM?+
Buy unlimited if you expect to use more than about 1.5 GB per day or simply do not want to track your usage. Check the daily full-speed allowance first; after it, many unlimited plans slow down considerably until the next day.
What happens if I run out of data?+
The connection stops or slows down, depending on the plan. Most providers let you top up in their app within minutes, so keep the app installed and your payment method ready.
