ESIMFUN eSIM Data Plans for United Kingdom

ESIMFUN does not provide a truly unlimited data eSIM for the United Kingdom. All of the plans listed under the “unlimited data plan” name actually have a fixed data cap of 100 GB for the validity period, after which the speed is throttled. For travelers who need high‑speed data up to 100 GB, ESIMFUN offers several fixed‑data options such as the 3‑day plan at $14.23 USD and the 5‑day plan at $22.78 USD, both covering the United Kingdom plus 30 other countries. These fixed plans can be more cost‑effective for most users, while the capped “unlimited” options may be suitable for those who require a short‑term high‑speed burst of data.

ESIMFUN does not provide United Kingdom eSIM plans that include a phone number or SMS capability; all available eSIMs from ESIMFUN for the United Kingdom are data‑only. Travelers can use VoIP applications such as WhatsApp, Telegram and iMessage over the data connection to make calls and send messages.

ESIMFUN offers 30 multi‑country data plans that are usable in the United Kingdom. These plans are priced between roughly $3.14 and $209.09 USD and provide data packages from 1 GB up to 100 GB, with validity periods ranging from one to thirty days.
