eSIM Saily pour Switzerland en 2026

A large range of plans makes data sizing the main decision for Switzerland: the main risk is buying more than a fortnight needs, so the table’s allowances and validity matter more than a fixed catalogue choice. Saily has not published which Swiss operators it uses, leaving the radio side unknown rather than bad; its fastest stated technology and traffic breakout are also not stated. Saily does not say whether an exhausted plan can be topped up, so check whether extension is possible before buying.
