BNESIM does not offer a true unlimited high‑speed eSIM plan for Iceland. All of their Iceland‑specific options provide fixed data allowances, such as the 100 GB plans that are valid for 30 days or have no expiry, and the “Iceland Unlimited 10 days” plan, which offers 3 GB per day at full speed and then throttles to 1 Mbps afterward. Travelers looking for larger data bundles may choose one of the 100 GB fixed plans, which can be more cost‑effective than a daily‑limited option, especially if the user expects to use a substantial amount of data over the trip.
