eSIM Firsty pour Iceland en 2026

Firsty has not published which operators it uses in Iceland, so the radio side is unknown rather than a sign of poor coverage; the practical details to assess are in the table above. Its large range of plans makes sizing the real choice, with the risk of buying more data than a fortnight needs. 5G is the fastest technology Firsty lists here, although that is a ceiling rather than a promise on every handset or street. Traffic breakout is also not stated. Top-up is stated as supported, so an exhausted plan can be extended rather than rebought.
