mobineX does not provide a truly unlimited data eSIM for Iceland. All plans that carry the word “Unlimited” in their name actually include a high‑speed data cap— for example, Unlimited Standard delivers only 1 GB of 5G data per day and then throttles to 128 kbps, while Unlimited Gold offers 5 GB before the speed drops to 1 024 kbps. The plan labeled “Unlimited – 10 Days” allows 65.09 GB for ten days; after the allocation is reached the high‑speed rate is reduced. These named plans are therefore fixed‑data options rather than true unlimited service.
Travelers who need larger data allowances can choose from the fixed‑data catalog, such as the 150 GB plan valid for 90 days at $230.50 USD or the 100 GB plan for 60 days priced at $95.70 USD. Another available option is the 100 GB plan for 180 days, also at 5G speed. Selecting a fixed data plan can be more cost‑effective for heavy data users, because the data cap is clear and there is no sudden throttling once the limit is reached.
