Good to know
The Channel Islands sit outside the UK's domestic network and the EU roaming zone, so some British and European plans quietly add charges in Guernsey — an eSIM keeps your data cost fixed.
Prepaid, honestly.

Fixed-data bundles have no daily cap — the gigabytes are yours until they're used or the plan ends. Every plan is prepaid: the checkout total is the whole bill, and we never add overage charges.

Hotspot support varies by plan and destination — where it's available for your plan in Guernsey, it's shown in the plan details before you pay.

The Guernsey eSIM guide.

Guernsey packs cobbled harbour lanes, cliff-top walks and hidden bays into just a few square miles. Between St Peter Port's seafront cafes, ferry hops to Herm and Sark, and drives out to Cobo Bay, a steady eSIM keeps maps, tide times, boat schedules and messages home running without a roaming bill.

How it works on the day

Add the eSIM before you fly or sail, then land at Guernsey Airport or St Peter Port harbour already online. It connects to local networks like Sure and JT automatically — no SIM swap, no hunting for island Wi-Fi on arrival.

Choosing your days

Most visits run a long weekend to a week — plenty for Guernsey plus a day trip to Herm or Sark. Short-break data bundles or a simple day rate suit the pace; top up if you island-hop for longer.

The short version.

A travel eSIM is data only. It sits next to your home SIM, so your number, texts and WhatsApp carry on as normal. Pick a bundle of GB sized to the trip. Install it on Wi-Fi before you fly — the days only start once it first connects in Guernsey, and it finds a partner network on its own.

Made for your kind of trip.
