Flysimio does not provide a truly unlimited data eSIM for the United Kingdom. The plan titled “United Kingdom Unlimited” actually offers a 2GB per day high‑speed allowance for a 7‑day period, so the data is capped and the speed is reduced after the daily limit is reached.
Travelers who need more data can choose from Flysimio’s fixed data plans, such as the 50GB 30‑day or 50GB 180‑day options, which give a set amount of high‑speed data that must be used within the specified validity period. These fixed plans can be more cost‑effective for most users, unless a traveler expects to consume data well beyond the available allowance.
