Jetpac does not provide a truly unlimited data eSIM for Iceland. The plans that carry the word “Unlimited” in their name actually give a daily allowance of 3 GB each for the plan’s validity period; once that amount is reached the speed drops to 1024 kbps.
Instead, Jetpac offers fixed‑data plans that may suit heavier data users. For example, a Global 50 GB plan is valid for 365 days and costs 249.00 USD, and a Europe 40 GB plan is valid for 30 days and costs 34.99 USD. These are just two of the fixed‑data options available and do not cover the entire range of plans Jetpac offers.
