ETravelSim does not provide an unlimited data eSIM for Jersey. The provider’s Jersey plans come in fixed data allowances, ranging from 10 GB to 50 GB with validity periods up to 365 days. For example, the Global Flex 365 eSIM 50GB plan is valid for 365 days and costs $109.99 USD, the Global Flex 365 eSIM 25GB plan is also valid for 365 days and costs $59.99 USD, while the Heritage Europe Pass 20GB plan is valid for 30 days and costs $27.00 USD.
Choosing a fixed data plan can be more cost‑effective unless a user requires an extremely heavy data consumption that would otherwise exceed any fixed allowance.
