Is 1GB enough for a week abroad?

For a light traveller — maps, messaging and a bit of browsing — roughly 1 GB can cover a week, or come close to it. If you scroll social feeds, stream music or watch video, 1 GB will usually run out in two or three days, so plan for more.

How much data does Google Maps use per day?

Active turn-by-turn navigation uses only about 5–10 MB per hour, so even an hour or two of directions a day adds up to a few tens of MB — small. The bigger cost is repeatedly searching and loading new map areas, which you can avoid by downloading offline maps before you fly.

Does WhatsApp use a lot of data?

Text messages are negligible — well under 1 MB an hour of normal chatting. Voice calls use roughly 0.5–1 MB per minute and video calls far more, around 5–15 MB per minute. The hidden cost is auto-downloading photos and videos in group chats, which you can switch off in the app's storage settings.

Should I get an unlimited data plan for travel?

For a trip of a week or less, usually not. Most travellers use somewhere between 1 and 5 GB, so a sized plan with a little headroom is cheaper and perfectly adequate. Unlimited only earns its place if you tether a laptop, stream a lot of HD video, or travel for several weeks.

What happens if I run out of data?

Your connection simply stops working until you top up or buy another plan — there is no shock bill, because travel eSIMs are prepaid. To avoid the mid-trip hassle, buy slightly above your estimate and keep an eye on your phone's built-in data counter.

How Much Data Do You Really Need for a Week Abroad?

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
