JamboSim eSIM Data Plans for Jersey

JamboSim does not provide a truly unlimited data eSIM for Jersey. The plans labeled “Unlimited” give up to 3 GB of high‑speed data per day; once that daily quota is reached the speed is throttled to about 1 Mbps.

If a traveler needs more data without the daily cap, JamboSim offers fixed data plans such as the 20 GB/30 days plan or the 10 GB/30 days plan, both of which allow the full data allowance to be used within the validity period. These fixed plans can be more cost‑effective for users who expect to consume a large amount 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 offers 12 single‑country plans and 18 multi‑country plans for Jersey. The plans span a price range from $1.99 to $105.99 and provide data caps between 200 MB and 20 GB. They include both fixed data amount plans, which give a set amount of data for the validity period, and daily data cap plans that limit how much data can be used each day.
