Unlimited Data eSIM: How It Works
We sell both: unlimited plans priced per day with no allowance cap, and per-GB bundles from 1GB to 50GB. They start their validity at different moments and only one of them tethers - here is how to pick.

What Does "Unlimited" Actually Mean?
Updated:
"Unlimited" rarely means uncapped. On many travel plans you get a set amount of full-speed data each day - often 1GB or 2GB - and once you pass it your connection is throttled to a much slower speed until the next day. Our unlimited plans work differently: there is no daily allowance to run down, though fair-use throttling may apply.
Neither shape is better in the abstract - they suit different trips. An unlimited plan is priced per day and saves you counting gigabytes, which suits short, data-heavy trips. A per-GB bundle from 1GB to 50GB suits longer trips where you would rather buy once and pace yourself, and it is the only one of the two that can share data by hotspot.
eSIMpass sells both across 200+ countries, delivered instantly by QR code with no app and no activation fee. One difference matters before you buy: a per-GB bundle only starts when the eSIM first connects at your destination, while an unlimited plan runs on the travel dates you select at checkout - the days count from your chosen start date whether the eSIM is installed or not.
How to Choose the Right eSIM
Match the plan shape to how you actually travel - then install it at the right moment.
Estimate your real usage
Streaming and hotspot use eat data fast; maps and messaging barely touch it. Be honest about your habits, then size a per-GB bundle to cover your days - or go unlimited and stop counting.
Buy your plan online
Choose your destination and plan, pay by card, PayPal or crypto, and your QR code arrives by email within minutes. No app to download.
Install at the right moment
Per-GB bundles can be installed at home on Wi-Fi days ahead - the clock only starts when you first connect at your destination. Unlimited plans run on the travel dates you selected at checkout: install any time before your start date, and make sure the eSIM is on your phone by that date, because the days count from it whether the eSIM is installed or not.
eSIMpass eSIM vs the Alternatives
How our per-GB and unlimited plans compare with daily-capped "unlimited" offers, local SIM cards and rented hotspots.
| Feature | eSIMpass eSIM | Daily-capped "unlimited" | Local SIM card | Pocket WiFi |
|---|---|---|---|---|
| Typical cost | Per-GB from £3-5 a week; unlimited priced per day | Often pricier for slower speeds after the cap | $10-30 plus a kiosk queue | $8-12 per day plus deposit |
| Setup | 5 minutes online - buy before you fly | Online, but read the fair-use cap | Find a shop, show your passport | Pick up and return a device |
| Speed limits | Per-GB: full speed until used. Unlimited: no allowance cap, fair use applies | Throttled hard once the daily cap hits | Depends on the local plan | Often throttled after a cap |
| Extra hardware | None | None | SIM tool and adapter | A device to carry and charge |
Both of our plan shapes avoid the daily cliff-edge that capped "unlimited" offers rely on - pick per-GB to tether and pace yourself, unlimited to stop counting.

What You Get Either Way
No daily cliff-edge
A per-GB bundle runs at full speed until it is used. An unlimited plan has no allowance to run down - fair-use throttling may apply, but there is no fixed daily ceiling that clamps you at 2pm.
Priced for the trip you are taking
Pay per gigabyte when you can predict your usage, or per day when you would rather not think about it. Either way you only pay for the trip in front of you.
