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

ActivityTypical 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 remotely1GB+ 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.

Quick self-test: add up your daily habits above. If you land under 1GB/day, a fixed-data plan (5-10GB) is almost certainly cheaper than unlimited for the same trip length. Cross 1.5-2GB/day and unlimited starts to pay for itself.

Who genuinely benefits from unlimited

Who's usually better off with a fixed plan

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.
