常见问题
Does JT cover the whole island?
Yes — Jersey is small enough that JT provides comprehensive coverage across all parishes. Coastal cliff paths and all beaches are within range.
What tide apps are important for Jersey beaches?
Jersey's tidal range (up to 12m) is one of the world's largest. The Mystic Tides or Easy Tide apps, or the Jersey Met tide chart, are essential for planning beach access — some beaches disappear completely at high tide.
Is there 5G on Jersey?
JT is expanding 5G coverage in St. Helier and main areas. Most of the island has reliable 4G.
Does EU roaming apply in Jersey?
No — Jersey is not in the EU or UK. EU roaming plans typically don't cover Jersey. Check your home carrier's roaming terms. A JT eSIM provides direct local network access.
Is there coverage in the German Underground Hospital?
The entrance and car park area have JT coverage. The tunnel interior may have weaker signal.
What transport apps work on Jersey?
Liberty Bus is Jersey's public bus network — check the LibertyBus app or website for routes. Taxis are available from St. Helier. No Uber operates on the island.
What speeds can I expect in St. Helier?
JT delivers 30–100 Mbps on 4G/5G in St. Helier and main areas.
What's the best way to find Jersey Royal potato dishes?
Jersey Royal season is April–July. Google Maps and TripAdvisor cover local restaurants well. Ask any local for their favourite fish and chip shop — the fish is exceptional.

可用网络：5G
Jersey is the largest of the British Channel Islands, a self-governing Crown Dependency with a Norman-French heritage, excellent seafood, and some of the best beaches in Northern Europe. JT (Jersey Telecom) provides 4G and expanding 5G coverage across the entire island. Data is most useful for the Liberation Bus network (Jersey's public bus service), navigating to the island's many beach access points, and booking Liberation Day events in May.
JT's coverage extends across St. Helier (the capital), St. Brelade's Bay, St. Aubin, and all parishes. The island is only 116km² so coverage is essentially complete across all inhabited areas. The coastal footpaths and cliff walks around the entire island have reliable signal. The German Underground Hospital (a WWII heritage site) has coverage at the entrance.
Jersey's beaches — St. Brelade's Bay, Beauport, Grève de Lecq, and Plemont — are the main draws and all have JT coverage. The tidal range in Jersey is extreme (up to 12m — one of the world's largest) and tide prediction apps are genuinely essential for beach access planning. Several beaches are only accessible at low tide.
Jersey has a distinct food culture — Jersey Royal potatoes (the world's best new potato), Genuine Jersey products, and fresh seafood define the cuisine. Google Maps and restaurant review apps are well-populated for the island.
Jersey uses British pounds sterling (GBP) and Jersey pounds (JPY, 1:1 with GBP). Euro is also accepted in many places. Jersey is outside the EU for VAT purposes — some duty-free shopping applies.
