South AmericaCayenneFrench Guiana eSIM and Travel Guide: Stay Connected in Cayenne, Kourou and the Amazon
French Guiana is a French overseas department on the north coast of South America, which means the euro, French law and EU roaming apply for travellers arriving with EU SIMs. However, mobile coverage is sharply split: Cayenne, Kourou and Saint-Laurent-du-Maroni have solid 4G from Orange Caraibe, Digicel and SFR Caraibe, while the vast rainforest interior has no signal at all. A Roamix French Guiana eSIM activates automatically on arrival at Cayenne Felix Eboue Airport on the Orange Caraibe network, which has the widest reach including some interior towns. Budget 5 to 10 GB for a two-week trip and cache offline maps before any jungle lodge or forest route.
Key Takeaways
- Orange Caraibe is the strongest network in French Guiana, reaching coastal cities and some interior towns where others drop out.
- A Roamix eSIM activates before you fly and connects automatically at Felix Eboue Airport, saving you a queue at the arrivals SIM kiosk.
- French Guiana uses the euro and follows French law; EU/EEA roaming rules apply for travellers with European SIMs, but Roamix is often more economical.
- The rainforest interior has no mobile coverage outside of a handful of river towns. Always download offline maps and lodge details before leaving Cayenne.
- Emergency services use the French standard 112 and 15/17/18 numbers, identical to mainland France.

Carrier roaming
EU travellers covered by Roam Like At Home
EU SIM holders roam free in French Guiana as it is an EU territory. Check your data allowance for overseas departments with your carrier.
For most visitors, a Roamix eSIM is the simplest and most cost-effective option, connecting you to Orange Caraibe on arrival with no setup at the airport.
Get connected the moment you land in French Guiana.
Get your French Guiana eSIMMobile Networks in French Guiana
French Guiana has three active mobile operators: Orange Caraibe, Digicel and SFR Caraibe. Orange Caraibe holds the largest footprint, reaching Cayenne, Kourou and some interior river towns via satellite backhaul. Digicel and SFR are reliable along the coastal corridor. A Roamix eSIM connects to Orange Caraibe on arrival at Cayenne Felix Eboue Airport, so you land already online without visiting a kiosk.
Widest footprint in the territory, covering Cayenne, Kourou, Saint-Laurent-du-Maroni and several interior communities via satellite-backed infrastructure. The safest choice for trips outside the coast.
Strong 4G along the coastal strip from Saint-Laurent-du-Maroni to Cayenne and Saint-Georges-de-l'Oyapock. Coverage deteriorates quickly into the interior.
Reliable in Cayenne and Kourou urban areas. Less reach than Orange Caraibe in towns away from the coast.
Typical Speeds
4G delivers 20 to 80 Mbps in Cayenne and Kourou. Speeds drop quickly as you move inland.
5G Status
5G has not launched in French Guiana. 4G LTE is the highest technology available in 2026.
If you are heading to the Guiana Space Centre for a rocket launch viewing, activate your eSIM in Cayenne before making the 60 km drive to Kourou, as coverage in the launch viewing areas at Agami Beach can be patchy.
The vast rainforest interior of French Guiana, including Saul, the Maroni basin villages and the Amazonian parks, has no mobile signal on any carrier. The only connectivity in deep jungle is via satellite devices. Even the N1 highway south of Roura loses coverage.
Networks use standard EU LTE bands. Most unlocked iPhones from XS onward and recent Android phones work without issue.
Data Usage Guide
Data needs are moderate for a coastal trip and essentially zero for deep jungle travel. Invest your data allowance in offline preparation before heading anywhere beyond the N1 highway.
Download the Organic Maps or Maps.me jungle overlays and your entire route as offline maps in Cayenne before any interior excursion.

Get your French Guiana eSIMMoney & Payments in French Guiana
French Guiana uses the euro. Card payments are accepted in hotels, supermarkets and larger restaurants in Cayenne and Kourou. Cash is essential for markets, jungle lodges and rural areas.
Cash vs Card
Cards work well in Cayenne and Kourou. Outside the coastal cities, cash is often the only option. Withdraw euros before leaving Cayenne.
ATMs
ATMs are available at Felix Eboue Airport and throughout Cayenne. Interior towns have no ATMs, so carry enough cash for your entire jungle or river trip.
Payment Apps
Apple Pay and Google Pay work in larger stores in Cayenne. French banking apps such as Lydia are popular locally. Mobile money is not widespread.
Daily Budget
Budget travellers spend around 80 to 120 EUR per day. Jungle lodge packages typically include meals and guides and cost 150 to 300 EUR per day all-inclusive.
Data cost: A Roamix eSIM plan covers a typical trip at a fraction of what international roaming from a home carrier would cost.
Getting Around French Guiana
French Guiana has limited road infrastructure. The coastal N1 highway links Cayenne, Kourou and Saint-Laurent-du-Maroni. Interior travel requires light aircraft from Cayenne airport or river pirogues from river towns. Taxis and rental cars cover the coastal strip.
Rental car and taxi on the coast
4G coverage is good along the N1 highway between Cayenne and Kourou. Use navigation apps freely on this route. Taxis can be booked via WhatsApp from Cayenne.

River pirogue
Main transport on the Maroni and Oyapock rivers. Signal is present at river towns but absent on the water between. Download maps and tide tables before departure.
Intercity buses
Shared taxis and minibuses run between Cayenne, Kourou and Saint-Laurent. Orange Caraibe covers most of this coastal corridor.
Regions & Travel
French Guiana is one of the most biologically diverse places on the planet, with over 90 percent of its territory covered by equatorial rainforest. The territory mixes a French Caribbean coastal culture in Cayenne with frontier jungle towns, Maroon communities along the Maroni River and one of the world's most active space launch facilities at Kourou. Data is essential on the coast and useless deep inland, so plan your connectivity windows carefully.
Best time to visit: July to November is the main dry season with the best jungle and river conditions. February to April is the short dry season. Rocket launch dates from the Guiana Space Centre are announced months in advance and attract visitors year-round.
Cayenne and the Cayenne Peninsula
The capital and main urban area of French Guiana, where colonial architecture, a lively covered market and Creole cuisine create an approachable base. Remi re-Montjoly beach is 15 minutes from the city centre.
Signal: Best 4G coverage in French Guiana from all three operators. Orange Caraibe and SFR deliver consistent signal across Cayenne, Remire-Montjoly and Matoury.
Kourou and the Space Coast
Home to the Guiana Space Centre, the world's most active commercial spaceport, Kourou draws visitors for rocket launches by Ariane, Vega and SpaceX launches from the European space complex. The surrounding coast has calm beaches and the Iles du Salut offshore.
Signal: Good 4G coverage in Kourou city and the visitor complex. The Agami Beach rocket viewing zone can be patchy; download launch schedules before you go.
Saint-Laurent-du-Maroni and the Maroni River
The second city of French Guiana sits on the Maroni River across from Suriname. It is the gateway to Maroon villages deep in the jungle interior and a base for river pirogue journeys.
Signal: Orange Caraibe provides reliable 4G in Saint-Laurent-du-Maroni town centre. Coverage disappears on the river within 20 km of town.
Saul and the Amazon Highlands
A remote highland village accessible only by light aircraft from Cayenne, Saul is the trekking hub for the Parc Amazonien de Guyane, the largest national park in the European Union.
Signal: No mobile coverage in Saul or the park interior. Download offline maps, lodge details and trail guides over wifi in Cayenne before flying in.
Maroni and Oyapock River Borders

Frequently Asked Questions
French Guiana eSIM, connectivity, and travel
What is the best eSIM for French Guiana?
Roamix is a top choice for French Guiana because it connects to Orange Caraibe, which has the widest network footprint in the territory including coastal cities and some interior towns. You activate before you fly and land connected at Felix Eboue Airport.
Do I need a SIM card for French Guiana?
You do not need a physical SIM. A Roamix French Guiana eSIM gives you local 4G on the Orange Caraibe network the moment you land, with no kiosk queue and no ID check at the airport.
Which network is best in French Guiana?
Orange Caraibe has the best coverage in French Guiana, reaching Cayenne, Kourou, Saint-Laurent-du-Maroni and some interior river towns where Digicel and SFR Caraibe do not reach. For any trip beyond the coast, Orange Caraibe is the only logical choice.
Does my EU SIM work in French Guiana?
Yes. French Guiana is an EU overseas department, so EU/EEA Roam Like At Home rules apply for European SIM holders. Check your operator's overseas data allowance, as some carriers cap data in overseas departments. A Roamix eSIM is often more economical than exhausting your home plan.
How do I set up an eSIM for French Guiana?
Buy a Roamix French Guiana plan before departure, install the eSIM over wifi, then enable data roaming on the Roamix line. When you land at Cayenne Felix Eboue Airport, the eSIM connects automatically to Orange Caraibe.
Is there mobile signal in the Amazon rainforest in French Guiana?
No. The vast majority of French Guiana's rainforest interior has no mobile signal on any network. Coverage exists only in Cayenne, Kourou, Saint-Laurent-du-Maroni, and a handful of interior river towns. Saul, the main jungle trekking hub, has no signal at all.
Do I need a yellow fever vaccine to enter French Guiana?
Yes. A valid yellow fever vaccination certificate is mandatory for entry to French Guiana and is strictly checked on arrival. Get vaccinated at least 10 days before travel. The vaccination is valid for life.
How much data do I need for French Guiana?
A coastal trip to Cayenne and Kourou uses around 4 to 6 GB over two weeks. If you plan jungle excursions to Saul or river trips, budget an extra 2 GB specifically for downloading large offline map packages before you go off-grid.
Can I watch the rocket launch from French Guiana with mobile data?
Yes. Kourou has good 4G coverage and you can follow the launch countdown on Arianespace's website or app at the Agami Beach public viewing area. Activate your Roamix eSIM before leaving Cayenne so you stay connected for the real-time countdown.
What currency does French Guiana use?
The euro. French Guiana is an EU overseas department and uses the same currency as mainland France. Card payments work well in Cayenne and Kourou. Bring cash for interior lodges, river pirogue operators and rural markets.
Is airport wifi enough at Cayenne Felix Eboue Airport, or should I get a French Guiana eSIM?
Airport wifi is available but unreliable for heavy downloads and stops at the terminal door. A Roamix eSIM keeps you connected from the moment you land through your transfers and onward journey, which matters most when navigating to remote lodges.
What are the emergency numbers in French Guiana?
French emergency numbers apply: 112 for all emergencies from a mobile, 15 for medical emergencies (SAMU), 17 for police and 18 for fire. These are the same as mainland France. In the remote interior, carry a satellite communicator as mobile networks do not reach most jungle areas.
Can I use WhatsApp and social media in French Guiana?
Yes. French Guiana has a fully open internet as a French overseas department. WhatsApp, Instagram, Google, FaceTime and all mainstream apps work without any restrictions or VPN.
What is French Guiana carnival like and when is it?
Cayenne Carnival is one of the most authentic in the Americas, running from January through to Mardi Gras in February or March. Neighbourhood parades happen every Sunday with growing intensity, culminating in the Grand Parade weekend with elaborate costumes and all-night street celebrations.
