eSIM Firsty pour Switzerland en 2026

Firsty has not published which operators it uses in Switzerland, so its radio options are unknown rather than necessarily limited; the table above is the practical reference. It has also not stated where traffic breaks out, so neither local latency nor apparent IP location can be inferred. The catalogue spans a large range, making data sizing the main choice, while 5G is the fastest technology listed, not a promise of service. Firsty states that top-up is available, so an exhausted plan can be extended rather than automatically rebought.
