eSIMCard does not provide a truly unlimited high‑speed data eSIM for Jersey. Every plan that carries the label “Unlimited” includes a fixed data allowance, such as 1GB per day or 2GB per day, after which the speed is throttled to a lower rate (512kbps or 2000kbps). Therefore, the data is not unlimited; it is limited by the specified daily cap.
Travelers who need unrestricted data use can choose one of the fixed‑data plans available for Jersey. For example, a 50GB plan for 30 days costs $31.39 USD, and a 40GB plan for 30 days costs $122.81 USD. These unthrottled plans provide a large amount of high‑speed data and can be more cost‑effective for users who expect to use a substantial amount of data during their stay.
