Lumbus does not provide a truly unlimited data eSIM for Jersey. All its Jersey plans are limited to a fixed amount of high‑speed data; the prorated “Jersey Unlimited” names only give 3 GB of 5G data per day and then reduce the speed to 1000 kbps.
Travelers who need more data can choose from Lumbus’s fixed‑data plans, such as the 50 GB plan valid for 180 days, or the 20 GB plan valid for 30 days. These plans offer large data allowances without speed throttling after a set period, and can be more cost‑effective unless a user requires an unlimited data experience.
