JamboSim eSIM Data Plans for Iceland

JamboSim does not offer a truly unlimited data plan for Iceland.
The plans that carry “Unlimited” in their name all have a data cap of 3GB per day; once that limit is reached the speed is reduced to 1000 kbps, so the data is not unlimited.

Travelers who need more data can choose from JamboSim’s fixed‑data eSIMs. For example, the 20GB plan for 30 days costs $12.99 and the 100GB plan for 180 days costs $195.99. These fixed plans are often more cost‑effective unless a user expects to use far more data than the daily cap allows.

JamboSim offers an eSIM that includes a phone number for use in Iceland with SMS capabilities. The plans provide a US-based (+1) dialing code, outbound voice, and outbound SMS functionality, but they do not support inbound calls or SMS. Prices range from $11.99 to $105.99, and validity lasts from 7 days up to 365 days. Users should confirm the specific levels of call and text support they need directly with JamboSim.

JamboSim offers 12 single‑country data plans and 34 multi‑country plans that cover Iceland. The single‑country options provide a fixed data amount for a set validity period, while the multi‑country packages bundle coverage across several European destinations. Prices span from $1.99 to $195.99 and data caps range from 200 MB to 100 GB. There are 12 daily‑cap plans that give a set amount of data per day and 34 fixed‑cap plans that give a single data allotment for the entire validity.
