How Much Mobile Data Do Travellers Really Use? Real Trip Data
By Sophie Hartley · Oct 4, 2026 · 4 min read
"How much data do I need?" is the first question before every trip, and most answers are guesses. This page is built on measured use instead: what 10,000 real international trips actually consumed, and what that means when you pick a plan.
Where the Numbers Come From
The figures below are from the Bcengi 2026 International Mobile Data Usage Report, published in October 2026. Bcengi took a random sample of 10,000 international trips made on its eSIMs between January and September 2026 and measured the mobile data each one used.
Three things to keep in mind while reading them:
- These are pay-as-you-go travellers. Everyone in the sample pays for the data they use rather than buying a fixed bundle, so they have a reason to be careful. Someone on an unlimited plan may well use more.
- Wi-Fi is invisible. The data shows mobile use only. A traveller who streams on hotel Wi-Fi every evening looks like a light user here.
- The source has an interest. Bcengi sells pay-as-you-go eSIMs and is one of the providers we list. The report says so itself and publishes its method; we have not audited the raw data. We quote it because measured use, with its limits stated, beats a guess.
How Much Data a Typical Trip Used
| Trip length | Median use | 9 in 10 trips stayed under |
|---|---|---|
| Long weekend (2–4 days) | 0.5 GB | 2.84 GB |
| One week (6–8 days) | 1.38 GB | 6.5 GB |
| Two weeks (13–15 days) | 3.16 GB | 11.9 GB |
| Over a month | 10.85 GB | — |
"Median" means half of the trips used less than this and half used more. On a week-long trip, three in four travellers used less than 3.24 GB.
Across all trip lengths, more than a third of trips (35.5%) used under 1 GB in total, and only about one in twenty (5.3%) used 20 GB or more.
About 0.22 GB a Day, Whatever the Trip Length
The most useful single number in the report: on any trip of four days or longer, the median traveller used roughly 0.22 GB (about 220 MB) a day. It barely changes between a five-day trip and a five-week one.
That gives you a quick rule of thumb: days × 0.22 GB is what a typical careful traveller uses. A 10-day trip comes to about 2.2 GB.
It Varies a Lot Between People
The median hides a wide spread. On a one-week trip the middle traveller used 1.38 GB, but one in ten used more than 6.5 GB, nearly five times as much. Maps, messaging and a bit of browsing sit at the low end; video, hotspot use and constant social uploads sit at the high end.
So treat the median as a floor for a light user, not a target for everyone. If you know you stream video on mobile data or share your connection with a laptop, plan for the "9 in 10" column instead.
Does the Destination Matter?
A little. Median daily use in some of the 25 destinations the report covers:
| Destination | Median use per day |
|---|---|
| China | 0.42 GB |
| Japan | 0.27 GB |
| Morocco | 0.27 GB |
| France | 0.26 GB |
| Italy | 0.26 GB |
| Thailand | 0.24 GB |
| United States | 0.23 GB |
| United Kingdom | 0.20 GB |
| Spain | 0.20 GB |
| Germany | 0.17 GB |
| Mexico | 0.10 GB |
China stands out: travellers there used over 50% more per day than in Japan, the next highest.
What This Means When You Pick a Plan
- A week away, light use: 3 GB covers about three in four week-long trips in this sample. It is also the size our destination pages use as the smallest sensible plan.
- A week away, you want no surprises: 9 in 10 week-long trips stayed under 6.5 GB, so a plan in the 5–10 GB range covers almost everyone.
- Two weeks: the median was 3.16 GB, and 9 in 10 stayed under 11.9 GB. A 10 GB plan is a comfortable middle.
- "Unlimited" plans: an unlimited plan usually gives you a daily allowance at full speed before slowing down, most often 2–3 GB. At a typical 0.22 GB a day, that is many times what most travellers use. Unlimited is worth paying for if you stream or tether, not as a default. See unlimited plans with their daily allowances side by side.
- A common 5 GB pack often does not fit: in the report's hypothetical comparison, 54% of trips would have used less than half of a 5 GB allowance, while 29% would have needed more.

Work Out Your Own Number
Your own habits matter more than any average. The travel data calculator builds an estimate from what you actually do (maps, video calls, streaming, social media) and shows it next to the real-trip benchmark from this page. If you already know roughly how much you need, Find My Plan shows the cheapest plan that covers it for your destination and dates.
