No, Qrispy eSIM does not provide an unlimited data eSIM for Iceland. All of the Iceland plans listed are Pay‑as‑you‑go, meaning the data amount shown (for example 10GB, 5GB, 3GB, 2GB, or 1GB) is a reference for how much data the purchased credit buys at the current local rate, not a hard cap. The credit does not expire, so any unused data remains available for future use and can be topped up whenever needed.
Because the plans are Pay‑as‑you‑go, travelers only pay for the data they actually use, which can be more cost‑effective than a fixed unlimited plan unless the user is an extremely heavy data consumer. Examples of the available options include the 10GB plan priced at $27.00 USD and the 5GB plan priced at $13.50 USD, both of which allow tethering and are valid for use in Iceland.
