JamboSim eSIM Data Plans for Guernsey

JamboSim does not provide an unlimited data eSIM for Guernsey. All available plans list a specific data cap, such as 20 GB or 10 GB. For example, the eSIM JamboSim Global 20GB / 30 days plan offers 20 GB of high‑speed data over a 30‑day validity and the eSIM JamboSim Global 10GB / 180 days plan supplies 10 GB for 180 days. Choosing a fixed data plan like these can be more cost‑effective for travellers who need a predictable, moderate amount of data, whereas very heavy data users may consider topping up a Pay‑as‑you‑go credit instead.

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 offers 18 multi‑country data plans for Guernsey. The plans range in price from $1.99 to $105.99 and provide data caps between 200 MB and 20 GB, with validity periods from 3 to 365 days. Tethering is allowed on some of these plans.
