eSIM EarthESIM pour Guernsey en 2026

EarthESIM has not published which operators it uses in Guernsey, so the radio side is unknown rather than a sign of poor coverage. Its large range of plans makes sizing the real decision; the risk is buying more data than a fortnight actually needs. The provider states that tethering is supported, so a laptop can use the phone’s connection, but it does not say whether an exhausted plan can be topped up. That extension detail is worth checking before buying.
