Zwitchy does not provide a true unlimited data eSIM for Iceland. All plans that include “Unlimited” in their name actually deliver a fixed amount of high‑speed data, in this case 3GB per day, and the speed is throttled to 1000kbps after the daily limit is reached. These are fixed‑data plans that expire after a set number of days.
For travelers who need a larger data allowance, Zwitchy offers fixed‑data plans such as the Iceland · 50 GB · 30 days plan, which provides 50GB of high‑speed data for 30 days, or the Iceland · 30 GB · 30 days plan for 30 GB. These options may be more cost‑effective for heavy data users compared to the “Unlimited” plans with daily caps.
