MeSIM does not provide an unlimited data eSIM for Jersey. The provider’s Jersey‑specific offerings are fixed data plans, such as the Jersey 20GB 30Days plan that gives 20GB of data for 30 days and the Europe 50GB 180Days plan that supplies 50GB for 180 days. These plans have a hard data cap and a set validity period.
For travelers who need more data than the fixed bundles allow, a Pay‑as‑you‑go option would be an alternative, but it is not listed for Jersey in the current catalog. Choosing a fixed data plan can be more cost effective for most users unless you expect to use a very large amount of data.
