Key takeaways
Jersey is a self-governing Crown dependency in the English Channel with two main mobile operators: Sure (which absorbed Airtel-Vodafone in 2024 and is investing in 5G) and JT (Jersey Telecom). Because Jersey sits outside UK and EU mobile roaming zones, most UK and European SIMs incur roaming charges here. A Roamix Jersey eSIM connects you to local network speeds on arrival at Jersey Airport without extra charges. Budget 2 to 4 GB for a week on the island, and download offline maps before cycling the quiet country lanes or exploring the remote north coast bays.
- Jersey is outside UK and EU mobile roaming zones, so most UK and European SIMs charge roaming fees on the island.
- Sure and JT both provide 4G island-wide; 5G rollout is planned with Sure committing a 48 million pound investment.
- A Roamix eSIM activates on arrival at JER Jersey Airport and avoids the roaming charges that catch most first-time visitors off guard.
- The island is tiny (116 square kilometres) but extremely well connected within its borders; the main gaps are in remote north coast cliffs and the inland parish valleys.
- Jersey produces its own pound notes (also GBP-equivalent) that cannot be spent off the island, so spend or exchange them before leaving.
Best way to get data in Jersey
For UK and European visitors, a Roamix Jersey eSIM is the smart choice: it avoids the roaming charges that catch most home SIM holders off guard and provides fast local JT or Sure network speeds from arrival.
| Option | Best for | Good to know |
|---|---|---|
| Roamix eSIMRecommended | Best for: UK, Irish and EU visitors to avoid roaming charges | Connects to JT or Sure local network on arrival, bypassing roaming fees that most UK and European SIMs incur because Jersey sits outside standard roaming zones. |
| Local physical SIM | Best for: Extended stays needing a local Jersey number | Available from JT and Sure stores in Saint Helier. Requires ID and an in-person visit. |
| Pocket wifi | Best for: Groups wanting shared data | Limited availability on the island; adds a device to charge and must be returned or disposed of at trip end. |
| Carrier roaming | Best for: Very short stays with no time to set up | Most UK and EU SIMs incur roaming charges in Jersey. For a week-long stay, those charges can exceed the cost of a Roamix plan significantly. |
Hotels, guesthouses and most cafes in Saint Helier and the main resort beaches offer free wifi. Coverage is generally good in settled areas. Mobile 4G is more reliable for navigation on the north coast cliffs and cycling routes.

How to set up a Jersey eSIM
A Roamix Jersey eSIM is best installed over wifi before your flight or ferry. It activates automatically when your device picks up JT or Sure on arrival at Jersey Airport or the ferry terminal in Saint Helier.
- 1
Buy your Jersey plan on the Roamix Jersey eSIM page before departure.
- 2
Scan the QR code or tap to install the eSIM over wifi at home.
- 3
Label it Roamix and keep your home SIM as primary for calls and texts.
- 4
Enable data roaming for the Roamix line only.
- 5
Land at JER or arrive by ferry and the eSIM connects automatically to JT or Sure.
Works on eSIM-capable phones including iPhone XS and newer, Google Pixel 3 and newer, and recent Samsung Galaxy models. The phone must be carrier unlocked.
Roamix sets the APN automatically on most devices. If data does not start after arrival, apply the APN from your order and toggle airplane mode off and on.
No data on arrival usually means data roaming is disabled for the Roamix line. Check phone settings, confirm data roaming is on for the Roamix SIM and restart if needed.

Getting around Jersey
Jersey is compact and most points are within a 30-minute drive. A combination of car hire, cycling and the Connex bus network covers the whole island. Data helps with bus times, cycling route navigation and finding the tidal crossing windows for Elizabeth Castle and Seymour Tower.
Car hire
Most practical for island-wide exploration. Drive on the left. Jersey speed limits are low (35 mph island maximum). Use Roamix data to navigate country lanes with Google Maps and check parking at beach car parks.
Connex Bus
Jersey's bus network serves all main beaches, parishes and tourist sites from Saint Helier. Download the LibertyBus app over Roamix data for timetables and real-time service updates.
Cycling
Jersey has an excellent network of quiet cycling routes. Download the Jersey cycling app or an offline route map over Roamix data in Saint Helier before cycling the north coast or Green Lanes.
Ferry
Condor Ferries run between Saint Helier and Poole, Portsmouth and Saint Malo. Ferries also connect to Guernsey. Book, check sailing status and receive updates over Roamix data.
Download the LibertyBus app over your Roamix connection for bus timetables. Google Maps covers Jersey roads reliably for cycling routes and driving.
Money and payments in Jersey
Jersey issues its own pound notes (Jersey pound), which are worth exactly one GBP but cannot be spent anywhere outside the Channel Islands. Spend or exchange them before leaving. Jersey notes are not accepted in UK shops.
- Cards and cash
- Cards and contactless payments are accepted almost everywhere in Saint Helier and the main tourist areas. Carry a small amount of GBP cash for beach kiosks, some parish markets and tipping.
- ATMs
- ATMs are available in Saint Helier dispensing Jersey pounds and GBP. Use Lloyds or Barclays ATMs to avoid third-party fees.
- Payment apps
- Apple Pay and Google Pay are widely accepted across Jersey, identical to the UK.
- Tipping
- Tipping follows British norms: 10 to 15 percent at restaurants (check whether service is included), rounding up for taxis is standard.
Daily budget
Jersey is an affluent destination with costs broadly comparable to London or slightly higher. Budget travellers spending around 80 to 130 GBP per day; mid-range 150 to 250 GBP including a hotel and good seafood dinners.
Local tips for Jersey
- Language
- English is the everyday language. Jerriais, a Norman French dialect spoken for centuries on Jersey, appears on road signs alongside English and is still taught in some schools, though very few people speak it daily. French is useful for visiting French visitors and the occasional ferry to Saint Malo.
- Food
- Jersey Royals (new potatoes with PDO status), Jersey dairy products (Jersey cream and butter are world-famous), fresh lobster, crab, ormer (abalone), sea bass and sole define the island's food culture. The waterfront in Saint Helier and Gorey Harbour have the best seafood restaurants.
- Plugs
- 230V, Type G plugs

Safety and health in Jersey
Jersey is very safe with a low crime rate and a relaxed island atmosphere. The main risks are tidal; Elizabeth Castle and Seymour Tower can be cut off by fast-moving tides, and north coast cliff paths require appropriate footwear. Check tidal times before any beach or tidal island walk.
- Stay reachable
- Keep your Roamix eSIM active to check tidal crossing times for Elizabeth Castle, receive weather updates for cliff walks and call 999 in emergencies. The north coast cliffs and Plemont Bay steps are the highest-risk walking areas.
- Health
- Healthcare is provided by the Jersey General Hospital in Saint Helier. UK residents are not automatically entitled to free healthcare in Jersey; private travel insurance is recommended for all visitors.
- Tap water
- Tap water is safe to drink throughout Jersey.
Networks and coverage in Jersey
Jersey is served by two main mobile operators: Sure, which absorbed Airtel-Vodafone in November 2024 and has announced a 48 million pound 5G investment programme, and JT (Jersey Telecom), the island's incumbent with around 52 percent market share and strong 4G coverage. Because Jersey is a Crown dependency, it sits outside both UK and EU roaming zones, meaning most British and European SIMs are charged for data and calls here. A Roamix Jersey eSIM connects to local JT or Sure networks on arrival at JER, giving you Channnel Islands speeds at local rates.
JT (Jersey Telecom)
The island's incumbent operator with around 52 percent market share and comprehensive 4G coverage across all 12 parishes. Historically the most trusted brand for island residents.
Sure
Formed after absorbing Airtel-Vodafone in November 2024, Sure provides strong competing 4G coverage across Jersey. A 48 million pound 5G commitment is the biggest telco investment in Jersey's history.
- Typical speeds
- 4G delivers 20 to 60 Mbps in Saint Helier and across the parishes. Rural north coast areas and cliff paths can drop to slower speeds.
- 5G
- 5G is not yet live as of mid-2026. Sure has committed to a major 5G investment programme; JT continues expanding its 4G footprint. Expect 5G in Saint Helier first.
JT and Sure are both solid choices on Jersey. For a short holiday, either provides reliable 4G in Saint Helier, at Saint Brelade's Bay and around Gorey Castle. A Roamix eSIM saves you from the roaming charges that catch most UK visitors off guard on their phone bill.
Jersey is tiny and coverage is excellent across most of the island. The more remote north coast cliff paths, some inland valley roads and the quieter western parishes can have slightly weaker signal. The island is well enough covered that offline maps are only really needed for cliff path hiking. Jersey networks use standard UK-compatible LTE bands. Most unlocked phones from iPhone XS onward and current Android devices work without issue.
Where to go in Jersey
Jersey packs remarkable variety into 116 square kilometres: world-class beaches, Iron Age dolmens, WWII occupation tunnels, a Norman castle on a tidal island, winding country lanes lined with Jersey Royal potato fields and some of the finest seafood in the British Isles. A Roamix eSIM keeps navigation and restaurant bookings live across all of it.
Best time to visit
May to September for the warmest weather (18 to 24C), all beaches open and a full events calendar. Liberation Day on May 9 brings the whole island out. October and April offer quieter conditions and excellent walking weather.
Saint Helier and the Central Parishes
The capital Saint Helier is Jersey's commercial and cultural hub, with the Central Market, the Elizabeth Castle on a tidal islet, the Jersey Museum, and a lively waterfront with restaurants and harbour ferries.
- Saint Helier Central Market
- Elizabeth Castle (tidal)
- Maritime Museum
- Liberation Square
- Royal Square Saint Helier
Excellent 4G from both JT and Sure across Saint Helier, the waterfront and the town centre. Signal is strong for navigating the market, booking restaurants and checking Elizabeth Castle tidal crossing times.
Gorey and the East
Gorey village is dominated by the imposing Mont Orgueil Castle rising above the harbour, one of Jersey's most photographed sights. The east coast has sheltered sandy beaches, the Seymour Tower tidal island and excellent seafood restaurants.
- Mont Orgueil Castle Gorey
- Gorey Harbour
- Seymour Tower tidal island
- Anne Port Bay
- La Mare Wine Estate
Good JT and Sure 4G in Gorey village and harbour area. The beach below the castle and the coastal path south have reliable signal.
Saint Brelade and the Southwest
The most popular beach parish, where Saint Brelade's Bay is Jersey's finest sandy beach with a Norman church on the headland. Ouaisne Bay next door is quieter and backed by heathland. The southwest cliff paths have spectacular views toward Guernsey.
- Saint Brelade's Bay
- Ouaisne Bay
- Saint Brelade's Church and Fishermen's Chapel
- Portelet Bay
- Corbiere Lighthouse
Strong 4G at Saint Brelade's Bay and the beach car park. The cliff path toward Portelet Bay can drop to weaker signal on the more remote headland sections.
The North Coast
Jersey's most dramatic coastline, where granite cliffs drop to sheltered coves, the coastal path traverses some of the best walking in the Channel Islands, Plemont Bay hides below the cliff, and the north coast parishes preserve the most traditional Jerriais character.
- Plemont Bay
- Bouley Bay
- Bonne Nuit Harbour
- Greve de Lecq beach
- North Coast Footpath
Signal is present on the main north coast road (B55) and in villages like Bonne Nuit and Bouley Bay, but the cliff path sections away from roads can drop to weak coverage. Download the north coast trail map in Saint Helier before setting out.
Saint Ouen and the West
Saint Ouen's Bay is Jersey's longest beach and the island's surf hub, a 5 km arc of Atlantic-facing sand perfect for surfing and bodyboarding. The west also holds the German Underground Hospital (Jersey War Tunnels) and the La Hougue Bie Neolithic mound.
- Saint Ouen's Bay surf beach
- Jersey War Tunnels (German Underground Hospital)
- La Hougue Bie Neolithic mound
- Kempt Tower
- Channel Islands Military Museum
Good 4G at Saint Ouen's Bay car park and the main beach. The more remote southern end of the bay and the inland lanes toward the War Tunnels have variable signal.
Off the beaten path
One of the largest and best-preserved medieval castles in the British Isles, rising dramatically from the rocks above Gorey Harbour, with 800 years of fortification layered through the towers and a panoramic view over the Normandy coast on clear days.
Signal: Good JT 4G at Gorey village, the harbour and the castle base. Signal is present throughout most of the castle approach and the lower fortifications.
A star-shaped artillery fort on a tidal islet in Saint Aubin's Bay, reached by a causeway at low tide or an amphibious ferry at high tide, with the garrison church of Saint Elizabeth and remarkable harbour panoramas from the battlements.
Signal: Good coverage at Saint Helier waterfront and on the dry-land approach. The castle island itself has JT 4G coverage. Signal is useful for checking the tidal crossing windows.
Jersey's most iconic image: the white granite lighthouse on a rocky Atlantic promontory at the island's southwestern tip, accessible on foot across a tidal causeway at low tide with spectacular views of the Channel Islands sea in all directions.
Signal: Good signal on the Corbiere headland and the approach road from Saint Brelade. The tidal causeway to the lighthouse island itself has intermittent coverage.
A chilling 1.5 km network of tunnels built by slave and prisoner-of-war labour during the German occupation of Jersey (1940 to 1945), now a deeply moving museum exploring the island's occupation experience with original artefacts and oral history.
Signal: Limited signal inside the underground tunnels, as expected. Download your entry ticket and audio guide over Roamix data in Saint Helier before making the drive to the site.
One of Europe's largest and best-preserved Neolithic passage graves, a 6,000-year-old burial chamber covered by a natural-looking mound, topped by medieval chapels and surrounded by beautiful countryside, with a geology museum and WWII bunker on site.
Signal: Good JT 4G at the La Hougue Bie site and the surrounding farmland approach. Signal is reliable for the audio guide download and navigation.
A hidden gem: a beautiful bay enclosed by dramatic cliffs accessible only by a long steep staircase, with an arched sea cave on the western side, golden sand uncovered at low tide and water clarity that rivals the Mediterranean.
Signal: Patchy signal at the cliff car park and very limited at the beach itself; the cliff stairs cut off most coverage. Download the north coast walking map in Saint Helier before making the trip.
An 18th-century defence tower built 1.5 km out to sea from the east coast of Jersey, accessible on foot across an extraordinary expanse of tidal mud and sand at low tide, with guided night-stay experiences available in the tower rooms.
Signal: Limited signal at the tower itself on the tidal flats; good coverage at Gorey and the Le Hocq beach access point. Download the tidal crossing guide in Gorey before setting out.
Jersey's most picturesque harbour village, with granite-built merchant houses, a historic fort on a tidal causeway, excellent seafood restaurants and a bike path running the length of Saint Aubin's Bay all the way to Saint Helier.
Signal: Strong 4G in Saint Aubin village, the waterfront and the fort causeway. Signal is reliable throughout the village for restaurant bookings and the coastal cycle route.
Bouley Bay on the northeast coast is Jersey's premier diving location, with clear Atlantic water, granite rock formations and a sheltered deep-water bay that also hosts the annual Bouley Bay Hill Climb motor sport event.
Signal: Variable signal at Bouley Bay, with good coverage at the harbour car park and the Black Dog pub, dropping on the cliff path access routes above.
A working estate producing Jersey wines, cider, spirits, preserves and chocolate in the island's pastoral interior, with guided tours of the winery and distillery, a cafe and a shop selling the full range of Jersey-made products.
Signal: Good JT 4G at the La Mare estate in Saint Mary parish. Signal is reliable for booking the chocolate and cider experience and navigating the country lane approach.

Through the year
- Spring

- Summer
- June to September is peak season with temperatures reaching 22 to 24C and the longest daylight hours. All beaches, heritage sites and restaurants operate at full capacity. Liberation Day in May marks the unofficial start of the tourist season.
- Fall
- October and November bring cooler temperatures (12 to 16C) but excellent walking weather, Tennerfest restaurant deals, the Jersey Festival of Words and the Air Display. Visitor numbers drop sharply, giving access to the island's best sites without crowds.
- Winter
- December to February is very quiet with temperatures of 5 to 10C. Many seasonal attractions close or reduce hours. Jersey is accessible year-round by air and ferry for visitors seeking a peaceful winter escape, and the island's mild Gulf Stream climate keeps it frost-free most winters.
Working remotely from Jersey
Jersey is a pleasant and practical remote work base, with a stable 4G network, numerous cafes with reliable wifi in Saint Helier, and a quality of life that makes it a genuinely enjoyable working destination. The island's low income tax rate makes it attractive for longer-term digital nomads.
- Connection
- 4G in Saint Helier handles video calls and tethering well. A Roamix plan of 8 to 10 GB suits a full working week with calls and uploads alongside beach evenings.
Use hotel or cafe wifi for large uploads and video-heavy meetings, with a Roamix eSIM as reliable mobile backup. The Jersey Chamber of Commerce area of Saint Helier has a concentration of co-working friendly cafes.
