eSIM Saily pour Jersey en 2026

Saily has not published which operators it uses in Jersey, so the radio side is unknown rather than evidence of poor coverage; the table above is the useful check. It has not stated where traffic breaks out or the fastest technology listed for the island, so neither apparent IP location nor a technology ceiling can be inferred. The catalogue is broad, making sizing the real choice, with a risk of buying more data than a fortnight needs. Saily does not say whether plans can be topped up, worth checking before purchase.
