eSIM Saily pour Guernsey en 2026

Saily has not published which mobile operators it uses in Guernsey, so the radio side is unknown rather than a sign of weak service; the practical details to assess are in the plan table above. Its broad catalogue makes sizing the real decision: the risk is buying more data than a fortnight needs, rather than having no choice. Saily also does not say whether tethering is available, a detail that decides whether a laptop can get online from the eSIM, so check that before relying on it for work.
