nextSIM does not provide a truly unlimited data eSIM plan for the Isle of Man. All plans that use the word “Unlimited” in their name actually have a fixed data cap, such as 1 GB per day or 2 GB per day, and after the allotted high‑speed data is used the speed is reduced (to 512 kbps or 2000 kbps).
Travelers looking for larger, non‑unlimited data may choose from nextSIM’s fixed‑data plans. For example, an eSIM 10GB 30 days plan is available for $28.33 USD and an eSIM 5GB 30 days plan for $15.66 USD. These options offer a predetermined amount of high‑speed data without the speed throttling that applies after the daily limits in the so‑called “Unlimited” plans.
