eSIM.sm does not offer an unlimited data eSIM plan for Jersey. The available options are fixed‑data plans, each with a specified data cap and validity period. For example, the “20GB 30 days – Jersey” plan provides 20GB of high‑speed data for 30 days at a price of $50.40 USD, and the “5GB 30 days – Jersey” plan supplies 5GB for 30 days at $21.80 USD. These plans can be suitable for typical travelers or moderate data users, but they may not be cost‑effective for very heavy data consumption. Choosing an appropriate fixed‑data plan can usually provide better value than seeking an unlimited option that is not offered by eSIM.sm.
