JamboSim eSIM Data Plans for Jersey

JamboSim does not offer a truly unlimited eSIM plan for Jersey. The plans labeled “Unlimited” actually provide 3 GB per day; once the limit is reached the speed drops to 1000 kbps. For travelers who need more data without incurring throttling, JamboSim offers fixed‑data alternatives, such as the 20 GB plan for 30 days at $20.99 USD and the 50 GB plan valid for 180 days at $109.99 USD. These plans give a larger overall data allowance without a hard daily cap, which can be more cost‑effective for users who consume a lot of data.

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 has 12 single‑country data plans available for Jersey, covering a price range of about $1.99 to $125.99 USD and data amounts from 200 MB up to 50 GB. No multi‑country plans are offered for Jersey.
