"How many gigabytes should I buy?" is the question every traveler asks. Here's the data-backed answer.
What actually uses data
- Maps / navigation: ~5 MB per hour of active use
- Messaging (WhatsApp, iMessage): ~1–5 MB per day
- Instagram / TikTok scrolling: ~100–200 MB per hour
- Web + email: ~50 MB per hour
- Video calls: ~250 MB per hour
- Streaming video (HD): ~1.5 GB per hour
Notice the gap: maps and chat are almost free; video is the budget-eater.
Three traveler profiles
- The navigator (maps, chat, occasional browsing): ~0.3 GB/day
- The sharer (social, stories, navigation, browsing): ~0.8 GB/day
- The streamer (video calls, YouTube, hotspot for a laptop): ~2 GB/day
How much to buy for a trip
- Weekend city break (3 days): 1–3 GB
- One week abroad: 3–5 GB (standard user)
- Two weeks / island-hopping: 10 GB
- Digital nomad / remote work: 20 GB or unlimited
Cut your usage without cutting your fun
- Download offline maps and playlists before you fly.
- Use hotel/café Wi-Fi for big uploads (photo backups, video posts).
- Turn on Low Data Mode so background apps behave.
Still not sure?
Round up one tier — the difference between 5 GB and 10 GB is small, and running dry mid-trip is the real cost. Or start smaller and top up the same eSIM if you need more; you only pay for what you use.
Simple guide: 0.3 GB/day for light, 0.8 GB/day for standard, 2 GB/day for heavy. Multiply by your trip length and add a little buffer.
