eSIM Guernsey

Guernsey is a British Crown dependency in the English Channel, 50km off the Normandy coast — a small, prosperous island known for its WWII German Occupation history, cliffside walks, and tax-haven financial status. Sure provides 4G coverage across the island, supporting seamless navigation for Castle Cornet, Hauteville House (Victor Hugo's exile home), and the cliff paths of the west coast. Data is essential for booking the Liberation Museum, navigating the coastal footpaths with digital guides, and checking ferry times from St Peter Port to the other Channel Islands.

Sure's 4G covers the full island — St Peter Port (the capital), St Sampson, and the main parishes. The coastal footpaths from Pleinmont headland to Petit Port Bay have coverage throughout. Herm Island (15 minutes by ferry from St Peter Port) has basic coverage. Sark (the car-free island) is a separate jurisdiction with no Sure coverage.

Castle Cornet in St Peter Port harbour has full coverage. The Little Chapel — a miniature mosaic chapel covered in seashells, one of the world's smallest chapels — has coverage. The German Underground Hospital at La Vassalerie, an extraordinary WWII tunnel complex dug by forced labour, has coverage outside but not underground.

Guernsey's famous beaches — Cobo Bay, Vazon Bay, Rocquaine Bay on the west coast — all have Sure coverage. The island is 15km across so coverage is complete for all main areas.

Guernsey uses the British pound but has its own Guernsey pound notes (accepted locally but not in mainland UK). English is spoken. The island has a rich WWII history — the only British territory occupied by Germany.
