eSIM Firsty pour Ukraine en 2026

Firsty has not published which operators it uses in Ukraine, 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 data sizing the main decision, with the risk of buying more than a fortnight needs, while the fastest technology it lists is up to 5G. Top-up is supported, so an exhausted plan can be extended rather than necessarily rebought.
