How Much Data Do You Actually Need for a Trip? (1GB, 5GB, 10GB Explained)
What 1GB of data really gets you abroad, hour by hour, app by app — plus a simple table that turns your trip length and habits into the right plan size.
The honest answer to "how much data do I need?" is that most travellers buy too much. Not because plans are oversized, but because gigabytes are abstract — nobody has an intuition for what 5GB feels like in daily use.
So let's make it concrete. Here is what data actually goes where, and how to turn that into a plan size in about two minutes.
What 1GB really gets you
These are realistic per-hour figures for a phone on a mobile network, not lab conditions:
| Activity | Data per hour | 1GB lasts |
|---|---|---|
| Google Maps navigation | ~5 MB | ~200 hours |
| WhatsApp / iMessage (text) | ~1 MB | effectively unlimited |
| Email and web browsing | ~30 MB | ~33 hours |
| Music streaming (normal quality) | ~70 MB | ~14 hours |
| Instagram / TikTok scrolling | ~250 MB | ~4 hours |
| Video call | ~350 MB | ~3 hours |
| YouTube at 720p | ~750 MB | ~80 minutes |
| Netflix in HD | ~3 GB | ~20 minutes |
Two things stand out. Maps cost almost nothing — the single most common travel fear is the least justified. And video is the entire ballgame: one evening of HD streaming burns more data than a week of maps, messaging and email combined.
If you remember one number, remember this: ordinary social media scrolling is about 250MB an hour. Everything else is either negligible or obviously expensive.
Turning that into a plan size
Find your row. These assume you have Wi-Fi at your accommodation in the evening, which is true for the large majority of trips.
| Your usage | Per day | 3 days | 1 week | 2 weeks |
|---|---|---|---|---|
| Light — maps, messaging, occasional photo | ~250 MB | 1 GB | 3 GB | 5 GB |
| Normal — the above plus social media, some uploads | ~600 MB | 3 GB | 5 GB | 10 GB |
| Heavy — daily video, frequent uploads, music on the go | ~1.2 GB | 5 GB | 10 GB | 20 GB |
| Working — laptop tethering, calls, cloud sync | ~2.5 GB | 10 GB | 20 GB | 30 GB+ |
Most holiday travellers are in the Normal row and are well served by 5GB for a week. The people who genuinely need 20GB usually already know it, because they hit their limit at home too.
What this costs
Prices below are the lowest listed price for each size as of August 2026. The YAZ30 code takes 30% off at checkout, so both figures are shown. Prices move with the catalogue — the destination page is always the authoritative number.
| Destination | 5 GB | 10 GB | With YAZ30 (5 GB) |
|---|---|---|---|
| Malaysia | $4.24 / 15 days | $6.35 / 15 days | $2.97 |
| Turkey | $4.82 / 10 days | $7.68 / 15 days | $3.37 |
| Vietnam | $5.01 / 7 days | $8.41 / 15 days | $3.51 |
| South Korea | $5.14 / 7 days | $8.64 / 15 days | $3.60 |
| Japan | $5.75 / 10 days | $9.26 / 15 days | $4.02 |
| Italy | $6.31 / 30 days | $10.91 / 30 days | $4.42 |
| United Kingdom | $6.31 / 30 days | $10.91 / 30 days | $4.42 |
| Thailand | $7.05 / 30 days | $10.71 / 30 days | $4.93 |
Validity is shown alongside each price because it varies by destination — a cheaper plan with a shorter window is not automatically the better buy.
A week of normal use in most of these destinations lands between three and five dollars after the discount. That is the practical point of estimating properly: the difference between a right-sized plan and a panic-bought large one is usually larger than the cost of the plan itself.
Three ways travellers waste data
Autoplay video. Social apps play video automatically as you scroll, at full quality, whether you watch or not. Turning autoplay off roughly halves social media consumption. It is the highest-value setting change on this list.
Cloud photo backup. Your phone will happily upload every photo you take over mobile data, and holiday photos are large. Set backup to Wi-Fi only before you leave — this alone has emptied many a travel plan by day three.
Laptop tethering without thinking. A laptop treats any connection as home broadband: it syncs, updates and downloads full-size pages. If you tether, pause automatic updates and cloud sync first.
Buy small, top up if needed
Unused data is not refunded. Topping up takes two minutes from your phone and applies immediately.
Those two facts together point in one direction: start with the size your honest estimate suggests, not the size your anxiety suggests. If you run out, you are a couple of taps from more data. If you overbuy, that money is simply gone.
If you would rather not do the arithmetic, the package recommender takes your destination, trip length and usage style and returns a size — and every destination page lists its full range of plans with current prices.
Frequently asked questions
How much is 1GB of data?
1GB covers roughly 4 hours of scrolling Instagram or TikTok, about 14 hours of music streaming at normal quality, or around 200 hours of turn-by-turn navigation in Google Maps. It will not cover much video: 1GB is about 40 minutes of YouTube at 720p or 20 minutes of HD streaming. For a traveller who mainly uses maps, messaging and occasional social media, 1GB lasts one to two days.
How much data do I need for a one-week trip?
For most travellers, 5GB covers a week comfortably. That assumes normal use: maps, messaging, social media, some photo uploads, and hotel or cafe Wi-Fi in the evenings. If you stream video daily or use your phone as a hotspot, plan for 10GB instead. If you barely use your phone beyond maps and WhatsApp, 3GB is enough.
How much data does Google Maps use?
Very little — around 5MB per hour of navigation, because the map tiles are cached and only your position updates. Even two weeks of daily navigation rarely exceeds 500MB. Downloading an offline map area before you travel cuts this close to zero. Maps is almost never the reason a traveller runs out of data.
How much data does Instagram use per hour?
Roughly 250MB per hour of ordinary scrolling, and considerably more if autoplay video is on and the feed is video-heavy. Uploading stories adds about 5MB each. Turning off autoplay in the app settings is the single biggest data saving most travellers can make, and it typically halves social media consumption.
What happens if I run out of data abroad?
The connection stops rather than continuing at an extra charge — prepaid travel plans do not bill overage. You top up from your phone in a couple of minutes and the new allowance applies immediately. Because topping up is this easy, buying a small plan first and adding more if needed usually costs less than buying a large plan up front.
Is unused data refunded?
No. Unused data expires with the plan's validity period and is not refunded, which is exactly why buying more than you need is the most common way travellers overspend. Estimate from your real habits, start modest, and top up only if you actually need it.
Does a hotspot use more data?
The hotspot itself uses nothing extra, but the devices connected to it do — and laptops consume far more than phones because they download full-size web pages, sync cloud files and install updates. If you plan to work from a laptop, budget two to three times what you would for phone-only use, and disable automatic updates and cloud sync while you travel.
