A dash means the provider does not publish this, not that the feature is missing.
“Unlimited” plans are capped by a daily fair-use limit. The allowance shown is the provider's stated ceiling, not a speed guarantee.

Frequently asked about eSIMs for United Kingdom
What is the cheapest eSIM for United Kingdom?
Airalo at $4.00 for 1 GB over 3 days. That is the lowest price of the 69 plans tracked here. It is not the best value per gigabyte — small packages rarely are — so check the price-per-GB column before buying if you expect to use more than a couple of gigabytes.
Which eSIM gives the best value per GB in United Kingdom?
Amigo eSIM: 200 GB for 30 days at $26.00, which works out at $0.13 per gigabyte. Value per gigabyte matters more than headline price on any trip longer than a weekend.
Are there unlimited eSIM plans for United Kingdom?
Yes — 19 of the plans tracked here are sold as unlimited, from $4.00. Read them carefully: unlimited means full speed up to a daily allowance, then throttling for the rest of the day, and some carry a total ceiling as well. The provider's own wording is shown on every plan.
Which mobile networks do these eSIMs use in United Kingdom?
The providers that publish it list EE, Hutchison 3G, O2, Vodafone. Not every provider discloses its network partner, and where one does not, this site shows a dash rather than guessing.
How current are these prices?
They were last read from each provider's own page on 9/17/2026. Prices are re-checked every day and the per-plan date is shown on every row; if a provider cannot be read, its plans keep their previous figures and are marked as carried over.
Some links on this page are affiliate links. If you buy through them we may earn a commission, at no extra cost to you. It never changes the prices shown or the order of the results.
