Roambit does not provide an unlimited data eSIM plan for Iceland. The available plans in Iceland have fixed data caps: a 100GB plan valid for 30 days, a 50GB plan also valid for 30 days, and a 20GB plan for the same period. These plans include tethering and are available on 5G networks. For travelers who need a substantial amount of data, choosing one of the fixed‑data options can be more cost‑effective than purchasing a larger plan, unless the user is an extremely heavy data consumer that would require more data than is offered on any of the current plans.
