RedEx eSIM does not provide a true unlimited data eSIM for Iceland.
All available plans use a fixed‑data model, limiting the amount of high‑speed data that can be used during the validity period. For example, RedEx offers a 200 GB plan valid for 30 days or a 100 GB plan also valid for 30 days. These fixed data plans can be more cost‑effective unless a traveler requires usage beyond the allotted data. Even the plans labeled “Unlimited” in their names contain a specific data cap (e.g., 1 GB, 2 GB, or 3 GB per day) and then throttle speed after the limit is reached, so they are not true unlimited plans.
