JamboSim eSIM Data Plans for Jersey

JamboSim does not provide a truly unlimited data eSIM for Jersey. All plans marketed as “Unlimited” actually offer a capped daily allowance of 3 GB, after which speed is reduced to 1000 kbps. Travelers who need more data without throttling can choose from JamboSim’s fixed‑data options such as the 20 GB / 30 days plan or the 10 GB / 30 days plan for Jersey. These plans provide a larger total data allowance at a single price and may be more cost‑effective for heavy data users.

JamboSim provides eSIM plans that include a phone number and the ability to send SMS for use in Jersey. The plans range from 1 GB for 7 days at $11.99 USD up to 20 GB for 365 days at $105.99 USD, and are available for purchase via the JamboSim website. Each plan issues a phone number with the dialing code +1. Calls and SMS can be sent out from this number, but the plans do not include inbound voice or SMS reception. The contact number is a U.S. number rather than a local Jersey number, so it is suitable for outgoing international communication from Jersey. Users who need confirmation or more specific functionality should contact JamboSim directly.

JamboSim provides a range of data plans that include Jersey. For plans that cover only one country, there are 12 options available. In addition, Jersey is also covered by 18 multi‑country plans, allowing travellers to use data across several destinations. Across all plans the price ranges from $1.99 to $106.99, while the data caps vary from 200 MB up to 20 GB, with validity periods between 3 and 365 days. The plans are split into fixed data amount and daily‑cap options, giving travellers flexibility depending on whether they want a set amount of data for a period or a daily data allowance.
