eSIM Cards eSIM Data Plans for United Kingdom

eSIM Cards does not provide a truly unlimited high‑speed data plan for the United Kingdom. The plans that include “Unlimited” in their names actually cap the data at 750GB for 30 days; after the cap is reached the speed may be throttled, although the exact throttled speed is not specified.

For travelers who need a large, but finite, data allowance, eSIM Cards offers fixed‑data alternatives such as the UK EE 650GB for 30 days, the Europe 400GB for 30 days (which also covers additional countries), and the UK EE 350GB for 30 days. All of these plans deliver high‑speed data for 30 days at a set price and can be more cost‑effective than trying to stretch a capped “Unlimited” plan.

eSIM Cards does not sell United Kingdom eSIM plans that include a phone number or SMS capabilities. All available United Kingdom plans from this provider are data‑only, with no inbound or outbound voice or text service. Travelers can use popular VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging instead of a traditional phone number.

eSIM Cards offers 26 single‑country data plans and 9 multi‑country data plans for travellers in the United Kingdom. The plans span a wide price range from roughly $5.76 to $656.18 and data allocations from 1 GB up to 750 GB. Many of the packages use a fixed data allotment while others apply daily data caps, giving users flexibility between short‑term and longer‑term usage. The validity periods for these plans range from 5 to 720 days, allowing both quick stays and extended trips to be covered.
