eSIMX does not provide an unlimited data eSIM for Jersey. All available plans are fixed data bundles with a mandatory validity period, the longest being 30 days. For example, the Jersey 20GB 30Days plan offers 20GB of high‑speed data, while the Europe 50GB 30Days and Europe 100GB 30Days plans provide 50GB and 100GB respectively, each valid for 30 days.
Because the data allowance is capped at these amounts, selecting a fixed plan can be more economical for travelers with typical usage. If a user requires more data than the bundle offers, a new plan may be purchased, or additional data could be added through an alternative method, though that is not part of the current fixed offerings.
