Plans are ranked by a combination of real traveler usage, pricing, data value, and coverage reliability. Rankings update automatically as providers change their offerings.
Guernsey is a British Crown Dependency in the Channel Islands — autonomous from the UK but not part of the EU. This means UK travelers cannot rely on UK mobile roaming allowances in Guernsey; a separate travel eSIM or international roaming plan is needed. Two local operators serve the island: JT (Jersey Telecom, regional coverage) and Sure (formerly C&W). Coverage is excellent island-wide given Guernsey's small size. Budget eSIM options include MobiMatter from $1.50/GB, Revolut from £1.50, BetterRoaming, and SimCorner. Holafly offers unlimited data plans for Guernsey. The island uses GBP (£) and operates under Channel Islands regulations.
A travel eSIM is the fastest way to get connected — no SIM shop, no roaming charges, and your home number stays active.

Best eSIM for Guernsey by Traveler Type
Not sure which plan to pick? Here's what we recommend based on your travel style:
St. Peter Port & Castle Cornet visitors
St. Peter Port has excellent 4G and 5G coverage throughout — the harbor, High Street, Castle Cornet, and all town areas. A 1–3 GB plan for 3–7 days comfortably covers a typical Guernsey town visit.
Coastal walkers (Cliff Path, Fermain Bay)
Guernsey's cliff path and south coast bays (Fermain, Moulin Huet, Saints Bay) are all well-covered by 4G. A 1–2 GB plan handles maps, photos, and social media for a coastal walking holiday.
Island-hopping (Herm & Sark day trips)
Day trips from Guernsey to Herm and Sark are popular — Herm has basic coverage; Sark (car-free island) has very limited signal. Download offline maps for Sark before boarding the ferry from St. Peter Port.
UK travelers
UK travelers: your UK SIM roaming allowance does NOT cover Guernsey — Guernsey is a Crown Dependency outside the UK. You need a separate travel eSIM or will pay international roaming rates. Budget options from Revolut (£1.50) or MobiMatter keep costs low.
Rural & garden island explorers
Guernsey's interior lanes, German occupation tunnels, and Little Chapel have solid 4G coverage. A 1 GB plan for a 3-day visit is typically sufficient for navigation and social media on this compact island.
Mobile Networks & 4G/5G Coverage in Guernsey
Guernsey has 2 major mobile operators: JT, Sure. All offer nationwide 4G coverage, with 5G now available in major cities.
Coverage is near-universal across Guernsey given the island's compact size (63 km²). St. Peter Port, the Vale, Castel, and all parishes have excellent 4G. 5G is available in St. Peter Port via JT. Herm and Sark (smaller neighboring islands) rely on Guernsey's signal and have limited coverage.
Most travel eSIM providers use JT or Sure infrastructure in Guernsey — both consistently ranked among the best networks in the region. You'll get strong, reliable signal in all major tourist areas.
