JamboSim eSIM Data Plans for Iceland

JamboSim does not provide a truly unlimited high‑speed eSIM plan for Iceland. The plans marketed as “Unlimited” give 3GB of data per day and, once that daily allowance is used, the speed is reduced to 1000 kbps. Travelers who want more data without a speed drop can instead choose fixed‑data plans, such as the 20GB/30‑day or 50GB/30‑day options, which offer larger data caps with no throttling after the limit is reached. Selecting a fixed data plan can be more cost‑effective for heavy data users.

JamboSim offers eSIMs for Iceland that include a phone number and the ability to send SMS. The plans start at 1GB for 7 days for $11.99 USD and go up to 20GB for 365 days for $101.99 USD, with prices scaling accordingly. The included phone number uses the dialing code +1, so it is a U.S. number; calls can be made but not received, and SMS can be sent but not received. Users who need specific voice or messaging features should confirm details directly with JamboSim.

JamboSim offers a single‑country data plan specifically for Iceland. In addition, the provider runs multi‑country data plans that include Iceland among their destinations; the exact count of those plans that cover Iceland is not disclosed in the available summary.

The plans vary widely in price and data allowance. Prices span roughly from $1.99 to $185.99, while data caps range from as little as 200 MB up to 100 GB. Some plans impose a daily data cap (a fixed amount of data available each day), whereas others offer a flat data allowance that can be used at any time during the validity period. The common features among these plans include the option for tethering and a reduced speed threshold of 1000 kbps.
