Frequently asked questions about Guernsey eSIM

Does my UK plan work in Guernsey without extra fees?

DEPENDS on the carrier. Some UK plans (especially premium) include Guernsey and Jersey as 'UK + Crown Dependencies' at no extra (Three, EE, Vodafone). Others treat as roaming. Crown Dependencies are NOT part of the UK proper — verify with your carrier. A local Channel Islands eSIM avoids surprises if your UK plan doesn't explicitly include them.

Does my French EU plan work in Guernsey?

NO. Guernsey is NOT in the EU roam-like-at-home zone (British Crown Dependencies are outside the EU). Although Guernsey is 50 km from France, your Free, Orange or Bouygues plan will hit expensive international roaming. A local or Channel Islands eSIM is strongly recommended.

Is there coverage on Sark and Alderney?

Yes. Sark (medieval, no cars) has basic Sure 4G — useful for coordinating horse-cart rides or booking restaurants. Alderney (3rd main Channel island, flight access) has full coverage. Herm (day-trip from Guernsey) covered. Channel Islands archipelago is surprisingly well connected.
