nextSIM does not provide a truly unlimited data eSIM for Jersey. The plans that carry “Unlimited” in the name—such as eSIM Unlimited Standard 1 Day Jersey and eSIM Unlimited Plus 3 Days Jersey—offer only 1GB/day or 2GB/day of high‑speed data, after which the connection is throttled to 512kbps or 2000kbps. These are capped plans rather than unlimited ones, and the reduced speed applies once the data cap is reached.
Customers who need more data without the speed reduction can choose from fixed‑data plans. For example, the eSIM 20GB 30 Days Jersey plan provides 20GB of high‑speed data for $42.07, while the eSIM 10GB 30 Days Jersey offers 10GB for $24.25. Such fixed‑data options may be more cost effective for travelers who expect to use significant amounts of data in Jersey.
