A local SIM in Martinique is a French prepaid line, sold under French consumer rules and priced in euros, and for most short visits it costs more in its first month than a travel eSIM does. The operator a visitor can realistically walk in and buy from is Orange Caraibe, whose no-contract Card offer and internet recharges are published openly. Put the starter and a 10 GB recharge together and you pay around 30 euros before using a megabyte, while Nomad's 10 GB month costs roughly 16. The eye-catching 9.99 euro plans from RED Caraibe and Free Caraibe are monthly subscriptions built for residents, and Free's own contract summary says so. The picture changes for three kinds of traveller: those staying past a month, those who want a French number that a gite owner or dive shop can ring, and those who will spend long days on the Pelee side of the island, where Orange's network is the one to be on.

Four Retail Brands, Three Radio Networks
The shop signs outnumber the networks. Orange Caraibe is the incumbent, with its own grid of 203 4G sites and 15 5G sites on the island as of April 2025, and it is the brand most visitors end up buying because its prepaid range is sold without a contract or a bank mandate. SFR Caraibe owns the second network and markets low-cost subscriptions through RED Caraibe. Digicel, whose Antilles-Guiana company is registered in Ducos, runs the third network, and its radio sites have been shared since 2020 with Free Caraibe through the Madiacom joint venture. Free's Martinique company is registered in Fort-de-France.
For a traveller, the network behind the brand matters more than the logo. Orange has 5G in thirteen communes, including Saint-Pierre and Le Morne-Rouge on the slopes of Mount Pelee and Le Marin at the sailing harbour in the south. SFR lists 5G in Fort-de-France, Le Lamentin, Schoelcher, Le Robert and Sainte-Luce. Digicel and Free cover the populated coasts well, and every travel eSIM sold for the island uses Digicel.
Picking a network by where you will spend your days
Staying around Fort-de-France, Les Trois-Ilets, Sainte-Luce or Sainte-Anne, any of the networks will serve, and the choice comes down to price and paperwork. Basing yourself in the north, whether in a gite near Le Morne-Rouge, at Saint-Pierre for the diving on the 1902 wrecks, or out at Grand-Riviere, put Orange first, since it has built most densely and none of the eSIMs can reach it. Crewing a charter out of Le Marin, Orange's 5G in the marina and its coverage down the south coast make it the practical local choice.
The Orange Card, Its Recharges, and the eSIMs Beside Them
Orange Caraibe's prepaid product is called the Card Orange, sold without commitment and without a monthly bill. The online shop lists it at 15 euros, and it comes loaded with 1 GB of data at activation, 5 euros of calling credit valid for ten days, and a further 10 euros of bonus credit when you add your first recharge. Calls from the island to local, mainland French and European numbers cost 0.30 euros a minute, and the same rate applies to the Caribbean, Brazil and Suriname. The shop also shows a version with the SIM offered free, but it is delivered by post within six days, which is no help to someone arriving on Saturday. The recharges below are taken from Orange Caraibe's recharge page.
| Option | Price | What you get |
|---|---|---|
| Card Orange starter | 15 euros | SIM, 1 GB at activation, 5 euros credit, 10 euros bonus at first recharge |
| Internet recharge | 3 euros | 1 GB for 10 days |
| Internet recharge | 5 euros | 2 GB for 10 days |
| Internet recharge | 15 euros | 10 GB for 30 days |
| Internet recharge | 50 euros | 40 GB for 60 days |
| Recharge Max | 10, 15 or 20 euros | 1, 3 or 5 GB for 5, 10 or 15 days, plus unlimited calls to local and mainland numbers |
| Classic recharge | 30 euros | 30 euros of credit with a 5 GB data bonus, 60 days |
| Nomad eSIM | 19 dollars, about 16 euros | 10 GB for 30 days on Digicel |
| Airalo eSIM | 13.50 dollars, about 11.50 euros | 5 GB for 30 days on Digicel |
The arithmetic for a first month is simple. A starter plus the 15 euro internet recharge is 30 euros and gives you 11 GB and a French number. Nomad's 10 GB month is about 16 euros, and Airalo's 5 GB month about 11.50. So the eSIM wins the first month by roughly half, which is the opposite of what many travellers expect after seeing tourist SIM prices on the English-speaking islands to the south.
The local card catches up from the second month. Each further 10 GB is another 15 euros with no new SIM to buy, and the 50 euro recharge covers 40 GB across sixty days, which is the best rate on the island for a winter-long stay. Anyone renting a house in Sainte-Anne for the season or working from Martinique for two months will come out ahead with Orange.
RED Caraibe and Free Caraibe: Cheap, Monthly and Meant for Residents
Martinique has had a price war in mobile data since Free arrived in 2022, and the results are striking. Free Caraibe sells 150 GB for 9.99 euros a month and 300 GB for 15.99, with a 10 euro charge for the SIM or eSIM and no minimum term. RED Caraibe, on SFR's network, answers with RED MAXI at 9.99 euros for 150 GB and RED ULTRA at 15.99 euros for 300 GB on 5G where available, adding 30 GB or 40 GB for use in mainland France and Europe.
These are not tourist products. Free's contract summary, in the version dated 1 January 2026, states that the offer is reserved for subscribers who live in the local zone or can show a stable link to it, and that the plan is billed monthly. We could not find the equivalent eligibility wording on RED Caraibe's site, but it is sold the same way, as a rolling monthly subscription activated online. Signing either as a visitor means taking out a French phone contract and then cancelling it, and neither company promises to accept a foreign address or card.
Who these plans actually suit
People moving to Martinique for a job, a teaching post or a hospital placement, students at the university campus in Schoelcher, and anyone who spends several months a year in a family home on the island. For them the value is excellent. Free's first Martinique boutique, at the La Galleria shopping centre in Le Lamentin, is open Monday to Saturday from 9:00 to 20:30 and has kiosks that activate a SIM in a few minutes, and the company also runs around ten smaller corners in shops around the island.
A visitor looking for a cheap local line should therefore look at the Orange Card instead. It asks for identity at activation, as every French prepaid line does, but it does not ask for a local address or a monthly bank mandate.
European and Mainland French Lines: Test Before You Buy
A large share of Martinique's visitors fly in from Paris on Air France, Air Caraibes or Corsair, and most of them already carry a phone that works here. Because the island is an outermost region of the EU, the roaming regulation applies, and a German, Spanish or Belgian line uses its domestic allowance up to the operator's fair-use limit. Mainland French plans normally carry a stated monthly volume for Europe and the overseas departments on the same bill, and calls between the mainland and the departments have been charged at domestic rates since 2016.
A two-minute check before you pay for anything local
1. Find Martinique by name in your operator's list of EU or Zone 1 destinations.
2. Note the roaming data limit printed on your plan, which may be lower than your home allowance.
3. If you are on a mainland French plan, look for the line that says Europe and DOM, and read that number.
4. Switch data roaming on before the flight lands at Le Lamentin.
5. If the allowance will run short, top up with a small eSIM rather than a new French line.
The reverse is worth knowing too. Orange Caraibe's internet recharges can be used on the island, in the other overseas departments and in Europe, so a long-stay visitor who buys an Orange Card in Martinique keeps working data on a side trip to Guadeloupe or on a flight home via Paris. The subscription plans from RED Caraibe carry a separate mainland and Europe allowance of their own.
None of this covers British contracts, which lost the legal guarantee with Brexit, or anyone on a North American plan, who is back to day passes or an eSIM.
Where to Pick Up a Line, and Which Days to Avoid
Forget about picking up a card when you land. The shops and services listed by Martinique Aime Cesaire airport include a newsagent, duty free, gift shops, a currency exchange, a pharmacy and a luggage store, but no phone operator. The nearest dependable counters are in the shopping zones of Le Lamentin, a short drive from the terminal, including Free's boutique at La Galleria, and the operator boutiques in central Fort-de-France. Bring your passport, because a French prepaid line cannot be activated without an identity document.
Timing your purchase
Most shops in Martinique close on Sunday and many shut for a long lunch on weekdays outside the malls, so a Saturday evening arrival can mean two nights before you reach a counter. Buy on a weekday morning if you can. Once you have an Orange Card, top it up by dialling #124#, in the Orange et Moi Caraibe app, from your online account, or with a Flash recharge of any amount from 5 euros in an authorised shop. The Flash and classic recharges carry a data bonus that grows with the amount, from 50 MB on 5 euros to 10 GB on 50 euros.
Recharge before heading north. The switchbacks of the Route de la Trace, the trails on Mount Pelee and the road to Anse Couleuvre are all places where your signal is unreliable, and running out of data on a hiking day, with the app refusing to load, is avoidable. The same applies to a day on a catamaran from Le Marin or Les Trois-Ilets, where you may be offshore and out of range for hours.
Staying Put, or Moving On by Ferry
Martinique is often one stop of several. FRS Express des Iles sails from Fort-de-France to Roseau in Dominica in about two hours, to Castries in St Lucia in about ninety minutes, and on to Pointe-a-Pitre in Guadeloupe in around four and a half. An Orange Card keeps working in Guadeloupe, which is inside the same local zone, but it becomes an expensive roaming SIM the moment you land in Dominica or St Lucia, both outside the EU. Travel eSIMs split the region awkwardly too, and our Caribbean island-hopping guide shows which regional plans include Martinique, which is in practice only Holafly's.
Buy an Orange Card when
Stick with an eSIM when
Verified eSIM prices for all three providers are in the Martinique eSIM guide. The Aime Cesaire airport guide explains the terminal WiFi login if you need to install a plan on arrival, the Fort-de-France guide covers the capital's buses and boats, and the eSIM Finder will size a plan to your dates.
Frequently Asked Questions
How much does an Orange Caraibe prepaid card cost in Martinique?
Orange's online shop lists the Card Orange starter at 15 euros, including 1 GB of data, 5 euros of call credit valid for ten days and 10 euros of bonus credit on your first recharge. Data recharges then cost 3 euros for 1 GB over ten days, 5 euros for 2 GB, 15 euros for 10 GB over thirty days, or 50 euros for 40 GB over sixty days. You need a passport or national ID card to activate the line.
Can I get the 9.99 euro Free Caraibe or RED Caraibe plan as a tourist?
Realistically, no. Free Caraibe's contract summary dated 1 January 2026 reserves its 150 GB and 300 GB plans for people who live in the local zone or have a stable link to it, and both brands sell these as monthly subscriptions rather than prepaid packs. We could not find RED Caraibe's eligibility wording, but it too is a rolling contract. A visitor wanting a local line should buy an Orange Card instead.
Is there a phone shop at Martinique airport?
Not according to the airport's own list of shops and services, which covers a newsagent, duty free, gift and flower shops, a currency exchange, a pharmacy and luggage storage but no mobile operator. The closest counters are in the malls of Le Lamentin, including Free's boutique at La Galleria, and in central Fort-de-France. On a Sunday most of them are closed, so land with an eSIM or use the terminal WiFi.
Will a SIM bought in Martinique work in Guadeloupe or on the ferry to St Lucia?
In Guadeloupe, yes. Orange Caraibe treats Martinique, Guadeloupe, French Guiana, Saint-Martin and Saint-Barthelemy as one local zone, and its internet recharges also work in Europe. St Lucia and Dominica are a different matter: both are outside the EU and outside that zone, so data there is billed at international roaming rates. For a ferry trip south, use a regional eSIM or a separate plan for each island.
I have a German SIM. Do I need a Martinique SIM at all?
Probably not. Martinique is an EU outermost region, so your German plan should work at domestic rates up to its fair-use roaming limit. Check that your operator names Martinique in its EU zone list and see how much roaming data your plan allows. Only if that is too little, or you are staying for months, does a local Orange Card make more sense than a small top-up eSIM.
