ESIMFUN eSIM Data Plans for United Kingdom

ESIMFUN does not provide a truly unlimited data eSIM for the United Kingdom. The plans marketed as “unlimited data plan” actually cap high‑speed data at 100GB; once that amount is reached, the speed is throttled to a reduced rate not specified in the listing. For travelers who need more data but do not require unlimited traffic, fixed plans are available. For example, a 15‑day plan offers 100GB for about $66.22 USD, and a 30‑day plan provides the same data allowance for about $128.62 USD. These fixed‑data options give clear limits while still delivering a generous amount of high‑speed 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 32 multi‑country data plans that cover the United Kingdom. All of its UK offerings are part of this multi‑country portfolio; single‑country options are not available from this provider. The plans come in two main structures: ten daily‑data‑cap plans that replenish each day, and twenty‑two fixed‑data‑cap plans that grant a lump sum amount for the plan’s validity period. Prices for these plans vary from roughly $3.18 to $212.24, while the data caps range from about 1 GB up to 100 GB.
