Guide · Understanding eSIMs
Do you really need unlimited data abroad?
Last updated April 2026
Unlimited plans are the most heavily marketed eSIM option — and for a lot of trips, they're overkill. Here's how to tell, in under a minute, whether you're one of the travellers who actually benefits.
What actually uses data on a trip
| Activity | Typical data per hour |
|---|---|
| Maps navigation | ~5-10 MB |
| Messaging (WhatsApp, texts) | ~1-5 MB |
| Browsing, social media scrolling | ~50-150 MB |
| Video calls | ~250-500 MB |
| Streaming video (standard quality) | ~500MB-1GB |
| Hotspot for a laptop, working remotely | 1GB+ easily |
For most travellers, a week of maps, messaging, and moderate browsing adds up to 3-6GB total — comfortably inside a standard 10GB plan, with room to spare.
Who genuinely benefits from unlimited
- Remote workers hotspotting a laptop for video calls throughout the day.
- Content creators uploading photos and video regularly while travelling.
- Groups sharing one connection via hotspot, where combined usage adds up fast.
- Anyone who simply doesn't want to think about data — the convenience itself has value, even if the raw gigabytes go unused.
Who's usually better off with a fixed plan
- Short trips (under a week) with normal browsing and messaging habits.
- Trips where you'll be on hotel or café Wi-Fi most of the day.
- Budget-conscious travellers comfortable topping up in-app if they run low — most providers make this a 30-second process.
One important caveat: "unlimited" often has a fair-use cap
Many "unlimited" plans throttle speed after a certain daily threshold (commonly 1-2GB/day at full speed), and hotspot sharing is frequently capped separately from your own device's data. Always check the fine print — "unlimited" doesn't always mean unlimited hotspot too.
Our verdict
Do the quick maths above before defaulting to unlimited. It's the right call for heavy users and hotspot-sharers — and an unnecessary $15-25 premium for everyone else on a short, normal-use trip.
