Flysimio does not provide a truly unlimited data eSIM for Jersey. The plan called “Jersey Unlimited” offers a 2GB/day allowance for a 7‑day period, which is a fixed daily cap rather than an unlimited data supply.
Travelers who need more data can choose from Flysimio’s fixed data plans for Jersey, such as the 20GB 30‑day, 10GB 30‑day, 5GB 30‑day, or 3GB 15‑day options, all of which deliver high‑speed 5G data within the specified validity period. For those who also want coverage beyond Jersey, the Global139 20GB 90‑day plan provides 20GB of data for 90 days across Jersey and 126 additional countries. These fixed‑data plans are typically more cost‑effective for most users unless an extremely heavy data consumer requires a higher daily allowance.
