Short answer: most travelers use 0.5–1.2GB of mobile data a day. Business travelers and remote workers use 1–4GB, mainly because of video calls and laptop hotspotting. For a two-week holiday, 15–20GB covers most people.
We’ve published 13 data-usage studies, each for a different kind of trip. Families in Japan, backpackers in Thailand, business travelers in New York and more.
Read one on its own and you get one answer. Put them side by side and a clear pattern appears. That pattern is what this guide is about.
How much data does international travel need? All 13 trips compared
Here’s every study, converted to data per person per day so they can be compared fairly:
| Trip | Trip total | Per person, per day |
| Solo backpacker, Japan, 10 days | 4–8GB | 0.6–0.7GB |
| Backpacker, Thailand, 2 weeks | 10–18GB | 0.8–1GB |
| Solo interrailer, Europe, 3 weeks | 15–25GB | 0.7–1.2GB |
| Honeymoon couple, Bali, 1 week | 5–20GB for two | 0.4–1.4GB |
| Family of 4, Europe, 2 weeks | 30–45GB | 0.5–0.8GB |
| Family of 4, Thailand, 10 days | About 25GB | About 0.6GB |
| Family of 4, Bali, 10 days | 25–40GB | 0.6–1GB |
| Family of 4, Japan, 10 days | 40–60GB | 1–1.5GB |
| Digital nomad, Bali, 1 month | 20–35GB | 0.7–1.2GB |
| Digital nomad, Thailand, 1 month | 20–35GB (hybrid Wi-Fi) | 0.7–1.2GB |
| Business, New York, 4 days | 4–8GB | 1–2GB |
| Business, Europe, 1 week | 8–18GB | 1.1–2.6GB |
| Business, Tokyo, 4 days | 8–15GB | 2–3.8GB |
Family figures are each study’s total divided by four people and the number of days.
What the 13 studies show
1. Destination barely matters
A backpacker in Thailand, an interrailer in Europe and a nomad in Bali all land between 0.6 and 1.2GB a day. Japan, Europe and Southeast Asia look almost the same.
What you do matters far more than where you go.
2. Work is what moves the number
Business travelers use two to three times more than holidaymakers. The cause is almost always video calls. An HD group call uses about 1.5GB an hour, so a few meetings a day add up fast.
Remote workers who rely on phone hotspot go even higher. Our Thailand study found hotspot-dependent nomads using 50–90GB a month, against 20–35GB for those with good Wi-Fi.
3. Families use less per person than you’d think
A family of four doesn’t use four times a solo traveler’s data. Young kids mostly use downloaded shows or a parent’s hotspot. Per person, most families land at 0.5–1GB a day.
Teenagers are the exception. Short video apps like TikTok can use 800MB an hour.
4. Navigation is tiny
Most people worry about maps. They shouldn’t. Google Maps uses only a few megabytes an hour. Here’s how much data Google Maps really uses.
Which plan suits a two-week trip?
Take your traveler type, multiply the daily figure by 14, and add 20% for travel days:
| Traveler | Per day | 14 days + 20% | Plan to buy (BazTel Europe) |
| Light: maps, messaging, some browsing | About 0.6GB | About 10GB | 10GB, US$10 |
| Typical: plus social media and photos | About 1GB | About 17GB | 20GB, US$19 |
| Business, no laptop hotspot | About 1.5GB | About 25GB | 20GB plus a 5GB top-up |
| Heavy: daily video calls or hotspot | 2–3GB | 34–50GB | Unlimited, US$28 for 14 days |
| Family of four | 2–3GB for all | 30–45GB | One 50GB plan, or two 20GB plans |
Notice the heavy row. In Europe, unlimited at US$2 a day beats buying 50GB of fixed data. Our unlimited vs fixed data guide shows where the crossover sits. Asia and global plans cost more per GB, so check the prices for your region.
Quick calculator: size your plan in a minute
Add up a daily figure for each person on the trip:
| Who | Daily data |
| Adult, holiday use | 0.6GB |
| Teenager with social media | 1.2GB |
| Child who streams on mobile data | 0.3GB |
| Business traveler | 1.5GB |
| Remote worker using hotspot | 2.5GB |
Multiply the total by your trip length. Then add 20% for travel days and surprises.
Example: two adults and a teenager, 10 days. (0.6 + 0.6 + 1.2) × 10 = 24GB. Add 20% and buy about 29GB, or a 20GB plan with a top-up ready.
Running a little short isn’t a disaster, as long as you top up rather than switch back to your home SIM. Here’s what happens when travel eSIM data runs out.
Five ways to use less data abroad
- Download maps, playlists and shows on Wi-Fi before each travel day.
- Turn off automatic photo backup and app updates on mobile data.
- Take video calls on Wi-Fi where you can. Here’s how much Zoom uses abroad.
- Set a data warning on your phone. Here’s how on iPhone.
- Stop background apps. Our Samsung guide shows what to switch off.
Frequently asked questions
How much data do I need per day when traveling?
Most travelers use 0.5–1.2GB a day. Business travelers and remote workers use 1–4GB, mainly because of video calls and hotspotting.
How much data does international travel need for two weeks?
For most holidaymakers, 15–20GB. Light users manage on 10GB. Business travelers need about 25GB, and heavy users 35GB or more.
Is 10GB enough for two weeks?
Yes, for light use: maps, messaging and some browsing. If you use social media daily or make video calls, go for 20GB.
How much data does a family need?
A family of four typically uses 25–45GB on a 10–14 day trip. That’s about 0.5–1GB per person a day. Families with teenagers sit at the top of the range.
Does the destination change how much data I need?
Barely. Across our 13 studies, leisure travelers used similar amounts in Europe, Japan and Southeast Asia. What you do matters more than where you go.
How we built these numbers
Each study models a realistic itinerary using published app data rates and our own test trips, then adds buffers for travel days. Ranges reflect light to heavy users. Your own use will vary, so treat these as a starting point. Plan prices are BazTel’s Europe prices as of October 2026.
