JamboSim eSIM Data Plans for Guernsey

JamboSim does not provide an unlimited data eSIM plan for Guernsey. Instead the provider offers fixed‑data plans. One option gives 50GB of data valid for 180 days at a price of $109.99 USD, and another provides 20GB of data valid for 30 days at $40.99 USD. Choosing a fixed‑data plan can be more cost‑effective for most travelers unless the user requires an extremely high data volume.

JamboSim offers eSIM plans that include a phone number and SMS capability for travel to Guernsey. The plans range from 1GB of data with a validity of 7 days at a price of $11.99 USD to 20GB of data with a validity of 365 days at $105.99 USD.

All available plans use the dialing code +1, which is not a local Guernsey number; the plans allow outbound voice calls and outbound SMS, but do not support inbound calls or inbound texts. Travelers who need specific functionality are advised to confirm the details directly with JamboSim.

JamboSim’s offerings for Guernsey consist exclusively of multi‑country data plans; there are no single‑country plans available. In total there are 29 plans that include Guernsey. These plans vary in data allowance from 200 MB up to 50 GB and in validity from one to 365 days, giving a price range from roughly $1.99 to $109.99. The plans provide a straightforward data cap rather than a daily data limit, so customers purchase a fixed amount of data for the chosen validity period.
