St. Peter Port, the capital and main harbour, has excellent 4G coverage. The airport at St. Andrew and main road corridors have solid signal. Guernsey is a small island (about 65 square kilometers) so coverage is comprehensive across most populated areas.
Sark, one of the smaller Channel Islands, is car-free and has basic mobile coverage. Herm is tiny and has limited coverage. Alderney, the third main island in the Bailiwick of Guernsey, has coverage in St. Anne town. WWII bunkers, tunnels, and fortifications are tourist attractions across the island, but underground areas have no mobile signal. Australian travellers should confirm their handset is unlocked and supports the local network bands.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.

Does a HelloRoam Guernsey eSIM work on the island of Herm and Sark?

Is a HelloRoam Guernsey eSIM useful for an Aussie doing a brief Channel Islands stop after London?

Install the QR at home before your UK departure from Australia, and the plan is live when you arrive by Aurigny or Condor from Heathrow or Southampton. Plans start from A$7.15.
What is the best eSIM plan for a weekend visit to Guernsey?
For a 2 to 3 day weekend trip, a 3GB HelloRoam plan is more than enough for navigation, social media, and messaging. If you plan to video call from your accommodation, a 5GB plan gives comfortable headroom.

Yes, HelloRoam eSIMs work in Guernsey and connect to Sure and JT 4G LTE networks. Coverage reaches St. Peter Port, the airport, and main populated areas across the island.
Which network does HelloRoam use in Guernsey?
HelloRoam connects to Sure Guernsey and JT Guernsey, the island's two main mobile operators. Both provide 4G LTE coverage across the main island.
Is Guernsey covered by UK domestic phone plans?
Not always. Guernsey is a Crown Dependency, not part of the United Kingdom. Many UK carriers treat Guernsey as international. Check your specific carrier's policy. A HelloRoam eSIM gives you a flat prepaid rate without this uncertainty.
How much does a Guernsey eSIM cost?
HelloRoam Guernsey plans start at A$7.15. Most visits to Guernsey are short, so a small plan covers everything needed for a few days.

Sark has basic mobile coverage in the main village area. It is a car-free island. Coverage is not as comprehensive as on Guernsey island. Download offline maps and ferry schedules before travelling to Sark.
Does my eSIM work on Alderney?
Yes. Alderney has 4G coverage in St. Anne, the main town. Alderney is the third largest of the Channel Islands and has its own airport. Rural and coastal areas may have weaker signal.
What currency does Guernsey use?
Guernsey uses the Guernsey pound, pegged 1:1 to British pound sterling. UK pound notes are also accepted. Guernsey pound notes are not accepted outside the Bailiwick. Cards are widely accepted.
