New Caledonia eSIM for Nouméa and separate island journeys
Choose New Caledonia eSIM data for a Nouméa family or work stay, a road journey toward Bourail or a confirmed visit to Lifou or the Isle of Pines. Check current travel advice and transport arrangements before building the plan around an island connection.
Grande Terre is New Caledonia's main island, with Nouméa in the southwest and a mountain chain running along the interior. Bourail is a road destination on Grande Terre; Lifou and the Isle of Pines require separate island transport. The international airport at La Tontouta and Nouméa's Magenta airport are different places, so a flight connection can also need a ground transfer. Reception in the capital does not establish service along an inland road, at a remote bay or on every island. Confirm each stage before relying on online directions.
Refund policy
We always refund the full amount you paid when you request it, whether your eSIM is unused, partly used or fully used. There is no time limit for requesting a refund.
No first-use deadline
Validity does not start until your eSIM connects to a supported network at your destination. There is no deadline for first use. You can buy now and keep your plan for a future trip.

How eSIM works in New Caledonia
Install the profile over Wi-Fi on an unlocked phone with eSIM support before departure. Save the airport on each ticket, the local host and any confirmed onward transfer. After reaching New Caledonia, set Horizon as the mobile-data line and enable its data roaming, keeping automatic home-data switching off. Installing the profile does not start the validity period; it starts when the eSIM first connects to a supported network in New Caledonia. This is data-only service; local conditions, the handset and the exact supported location affect reception.

Size it to your trip
Pick the profile closest to your trip. The estimate assumes normal use — maps, messaging, photos, a short call home.
As a rule of thumb, a 3–4 day city break runs on about 1–3 GB, a one-week trip on 3–5 GB, a two-week multi-country tour on 8–12 GB, and working on the road takes about 1 GB a day, so 15 GB or more for two weeks.

- Messaging and photos
- A short call home most days
In total, a 1 GB data allowance covers roughly 330 shared photos, 17 hours of social media and browsing, 2.9 hours of video calls, 13 hours of music streaming, or about 200 hours of maps and navigation. Messaging apps barely use data.

Important cities in New Caledonia
Nouméa · City guide
Nouméa
Nouméa occupies a peninsula in southwestern Grande Terre. A waterfront accommodation address and an office elsewhere in the city still need separate pins, while a La Tontouta arrival should not be confused with Magenta. Keep the receiving host's details and confirmed pickup together, and review current local guidance before setting out for an appointment or onward connection.
Nouméa eSIM — set up before you flyBourail · City guide
Bourail
Bourail lies farther north on Grande Terre's west side. An address in the surrounding area may refer to a coastal property rather than the town itself, so ask the host for the final approach. Save the route before leaving Nouméa, and check current road conditions and access rather than making a navigation application's suggested journey the whole travel plan.
Bourail eSIM — set up before you flyIsle of Pines · City guide
Isle of Pines
The Isle of Pines, also known as Île des Pins, is southeast of Grande Terre. It cannot be added to a Nouméa road itinerary, and the practical arrival depends on the transport actually operating and booked. Confirm the meeting point and your accommodation transfer before leaving, then keep those details offline for a journey that may be beyond land reception.
Isle of Pines eSIM — set up before you flyLifou · City guide
Lifou
Lifou is one of the Loyalty Islands, separate from Grande Terre and the Isle of Pines. Obtain the exact receiving village and host details, rather than using the island name as a complete address. Check support for your intended location before purchase, and do not infer reception on another Loyalty Island from a successful connection during a Lifou stay.

Make the onward booking part of the decision
For a Nouméa office stay, the data decision may turn on work files and family messages. An island extension adds travel days, separate accommodation contacts and a greater need for saved instructions. Pick validity for both stages and compare the live allowance with any laptop use. Horizon includes free personal hotspot sharing on compatible devices during a New Caledonia stay, using the same balance. Horizon fixed-data plans have no throttling. Mainland France, Vanuatu and French Polynesia need their own explicitly listed coverage; a French or Pacific label alone does not extend this country plan.

Frequently asked questions
Does a mainland France plan necessarily include New Caledonia?
No. New Caledonia needs to be explicitly named in the selected offer. Its relationship with France does not make mainland coverage applicable, and a New Caledonia country plan does not include a stay in mainland France.
Are La Tontouta and Magenta the same airport?
No. La Tontouta International Airport is outside Nouméa, while Magenta is in the Nouméa area. Check both tickets and confirm the actual transfer and current operation before connecting between flights; do not use a generic Nouméa airport pin.
Can I treat Lifou or the Isle of Pines as a road day trip?
No. Both are separate islands requiring their own confirmed transport and receiving arrangements. Check current services, access and the return booking before committing to the visit, and keep those details saved without depending on reception during the journey.
Does a New Caledonia listing prove reception on every island?
It does not. Verify support for the specific island and locality you intend to use, including any Loyalty Islands stay. Mountain roads, remote bays and water between islands can be outside usable reception despite service in Nouméa.
What should I download before driving toward Bourail?
Keep the confirmed route, accommodation approach and host details offline. Review current official travel advice and local road information before departure, since a saved map does not establish that a route or site is currently accessible.
Can I share the plan for work during a Nouméa stay?
For a Nouméa work stay, Horizon includes free personal hotspot sharing on compatible devices. The laptop and phone draw from one allowance, so count document transfers and cloud syncing together and check the actual local connection before scheduling an online meeting.
Will this plan include a Vanuatu or French Polynesia connection?
No. Those are separate destinations from New Caledonia. If the itinerary includes a stay or mobile use there, read the destination list for that leg and arrange separate coverage where it is not explicitly included.
Can I keep my WhatsApp and phone number with the New Caledonia eSIM?
Yes. WhatsApp stays linked to your usual number and runs on the eSIM's data. On a dual-SIM phone, your usual SIM can stay on for ordinary calls and texts. Your home carrier may charge for calls, texts or data on that line, so turn off data roaming there.
Does the New Caledonia eSIM include calls and texts?
No. Horizon plans are data-only, with no phone number for calls or texts. Use apps such as WhatsApp or FaceTime over the eSIM's data, or keep your usual SIM on for ordinary calls and texts.
Do I need to turn on data roaming for the New Caledonia eSIM?
Yes. A travel eSIM connects to local networks as a roaming line, so turn on data roaming for the Horizon eSIM when you arrive. The plan is prepaid, so Horizon does not bill you after checkout. Keep data roaming off on your usual SIM to avoid charges from your home carrier.
What happens if I run out of data on the New Caledonia eSIM?
You can buy more. If your plan supports a top-up, My eSIMs shows the data you can add to the same eSIM. If it does not, buy another New Caledonia plan and install it the same way.
Will my phone work with the New Caledonia eSIM?
It will if your phone supports eSIM and is not locked to your home carrier. Many recent iPhone and Android models do, but some regional versions do not, so check your exact model on the supported devices page before you buy.
See supported devicesWill Horizon slow down my data?
No. Horizon fixed-data plans have no throttling. There is no daily limit that slows you down, so you can use your whole plan in one day if you need to. Your speed depends on the local network, your signal and how busy the network is. When your data allowance is used up, the plan stops rather than slowing down.
Can I get a refund if I already used some data?
Yes. We always refund the full amount you paid when you request it, whether your eSIM is unused, partly used or fully used. There is no time limit for requesting a refund.
