eSimfly eSIM Data Plans for United Kingdom

eSimfly does not provide a truly unlimited high‑speed data option for the United Kingdom. The plans labeled “Unlimited” actually grant a fixed allowance per day—either 1GB or 3GB—after which the connection is throttled to lower speeds. Travelers who need more data can choose from fixed data plans, such as a 50GB 30‑day plan or a 50GB 180‑day plan, which give a large, unthrottled data budget for the duration of the validity period. These fixed‑data options may be more cost‑effective for users who consume a lot of data during their stay.

eSimfly does not provide United Kingdom eSIM plans that include a phone number or SMS. The company only offers data‑only eSIMs for the UK, which work with high‑speed 4G or 5G networks. Travelers can still use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging.

eSimfly offers a total of 92 data plans in the United Kingdom when the two categories are combined. There are 26 single‑country plans dedicated to the UK alone and 66 multi‑country plans that include the UK as part of a broader coverage. The available plans span a price range of roughly $1.08 to $331.48 and a data cap ranging from 1 GB up to 50 GB, with validity periods from one day to one year. The catalogue includes both daily‑data‑cap options, which reset each day, and fixed‑data‑cap options that provide a set amount of data for the full validity of the plan.
