Verifying the information for Lempart Flex, there is no eSIM plan for the United Kingdom that offers truly unlimited data – every plan listed in the data set is capped, either by a fixed data allowance (e.g., 100GB for 30 days) or by a daily data limit (1GB/day) that is followed by a speed reduction. The plans bearing “Unlimited Data” in their name provide a certain amount of high‑speed data per day and then drop to a lower rate; the amount itself acts as a hard cap.
For users who need a large, predictable data allowance without a hard daily limit, Lempart Flex offers fixed‑data plans. One option is the “United Kingdom” plan, which gives 100GB of data for 30 days at a price of $62.49 USD, and another is the “EU + EFTA” plan with the same 100GB data cap but extended coverage to 36 countries for $83.99 USD over 180 days. Both options are valid for the specified period and do not impose a daily maximum, making them cost‑effective for heavy data usage within the United Kingdom.
