How Much Data Do You Really Need for a Week Abroad?
By eSIM Today Editorial7 min read

Most travellers use roughly 1–2 GB of data per week abroad for the essentials — maps, messaging and light browsing. Add social feeds, music and the odd video and that climbs to around 3–5 GB. If you stream a lot, tether a laptop or take work calls on the move, expect 8–15 GB or more. All of these are approximate ranges, not promises — your real usage depends on how you travel — but they are close enough to size a plan sensibly, and far more useful than the "just buy unlimited" advice you will read elsewhere.
This guide breaks those numbers down by traveller type, shows what each activity actually costs, and helps you pick a plan with enough headroom that you never think about it again.
Three traveller profiles
The easiest way to estimate your week is to find the profile that sounds most like you. These are typical ranges for seven days, assuming you are on Wi-Fi at your hotel each evening for the heavier stuff.
| Profile | Typical week | What's included |
|---|---|---|
| Light | ≈1–2 GB | Maps and navigation, WhatsApp or iMessage, occasional web browsing and email |
| Moderate | ≈3–5 GB | Everything above, plus social feeds, music streaming and short video clips |
| Heavy | ≈8–15 GB | Everything above, plus regular HD streaming, hotspot tethering and work video calls |
Two things shift you up a band. The first is video — streaming and video calls dwarf everything else, as the next section shows. The second is tethering: the moment you share your connection with a laptop or tablet, that device's updates, cloud backups and streaming all run through your travel plan. If either applies to you, size up.
Most leisure travellers land in the Light or Moderate band. You have to work fairly hard to reach Heavy on a phone alone — it usually takes a laptop or a lot of Netflix.
What actually eats data
Data usage is wildly uneven between apps. Navigation is almost free; HD video can burn through a gigabyte in under an hour. Knowing the rough hourly cost of each activity is the single most useful thing for estimating your trip, so here are typical approximate ranges.
| Activity | Approx. data per hour |
|---|---|
| Maps and navigation | ≈5–10 MB |
| Web browsing and email | ≈50–80 MB |
| Music streaming |
