Planning
How much data do you actually need for a trip?
Travel data usage is lower than people think for light users and much higher than people think for anyone hotspotting a laptop. Here is the realistic range.

Key takeaway
"The single biggest variable in travel data usage is not how long your trip is — it is whether you hotspot a laptop. Adding a laptop to a travel eSIM typically 5–8× total data usage."
Most first-time eSIM buyers either massively over-buy ("just in case I need 20 GB on a three-day city break") or massively under-buy ("1 GB should be fine for a month of remote work"). Neither is correct. Actual data usage for travel is predictable if you think through what you'll actually do.
Here are realistic sizing brackets based on real customer usage data, with the three variables that make the biggest difference.
Light leisure traveller: 1–3 GB per week
Maps, translation, WhatsApp, occasional photo upload, a few minutes of YouTube. No streaming, no hotspot. Typical for someone on a 7-day city break who uses hotel Wi-Fi for anything heavy. 1 GB for a weekend, 2–3 GB for a full week. Under-buying here is rare.
Standard leisure traveller: 5–10 GB per week
The same plus light video streaming on the train, Instagram reels, longer WhatsApp video calls, some evening Netflix. Still phone-only, no laptop. Typical for a two-week leisure trip. 5 GB covers a week comfortably, 10 GB covers two weeks.
Heavy traveller: 20 GB or unlimited per month
Video streaming on the go, multi-hour video calls, lots of photo and video uploads. Still phone-centric. 20 GB/month is the sweet spot for this profile. Unlimited is marginal unless you're doing multi-hour daily video calls.
Hotspot to laptop: unlimited is the only answer
The moment you start hotspotting a laptop, data usage explodes. Figma, GitHub, Loom, Slack, Zoom, and macOS background sync will chew through 20 GB in 2–3 days of normal work. Unlimited plans with generous Fair Use thresholds are the only sensible choice. Even then, expect to hit the daily Fair Use cap on heavy days.
Questions people actually ask.
- Video streaming. A single hour of HD Netflix is about 3 GB. An hour of Zoom HD video is about 1.5 GB. SD video roughly halves both. Maps are negligible — even Google Maps with offline cache disabled uses under 50 MB per day of heavy navigation.
