eSIMsData does not provide a true unlimited‑data eSIM for Jersey. The only plans marketed with the word “Unlimited” actually have a daily high‑speed allowance (either 1 GB or 2 GB per day) after which the speed is throttled to 1250 kbps or 2000 kbps.
Users who need more data can choose from fixed‑data plans, such as the 100 GB 30‑day plan for Jersey (or the 50 GB 30‑day option). These plans give a large, single data allowance that must be used within the validity period, and can be more cost‑effective for most travelers unless they require truly unlimited usage.
