ZenSim does not provide a truly unlimited data eSIM for Jersey. The plans that have “Unlimited” in their names, such as Jersey Unlimited STANDARD – 10 days and Jersey Unlimited STANDARD – 30 days, actually offer a fixed 3 GB/day data allowance, after which the speed may be reduced. If you need more data, ZenSim offers several high‑capacity fixed plans: a 20 GB plan valid for 10 days at $42.00 USD or for 30 days at $48.00 USD, a 10 GB plan valid for 10 days at $24.00 USD or 30 days at $27.00 USD, and a 5 GB plan for 10 days at $15.00 USD. These fixed‑data options may be more cost‑effective for heavy data users.
