eSIM French Guiana: 5G/4G for Cayenne & the Kourou Space Centre

Welcome to French Guiana, a unique department of France nestled in South America. Whether you are in Cayenne for business, or in Kourou for a mission at the Guiana Space Centre (Centre Spatial Guyanais), a high-speed, reliable data connection is non-negotiable.

Stay connected in this high-tech jungle with Cellesim's French Guiana eSIM plans, starting at just $5.29. Choose from 7 limited and 14 unlimited plans.

CRITICAL: Avoid the "South America" Roaming Trap

IMPORTANT WARNING: While technically part of France, French Guiana is in South America. For most non-EU carriers (from the US, UK, Canada, Asia, etc.), this territory is NOT included in any "European" roaming plan.

Your home carrier will charge you astronomical "Rest of World" or "South America" roaming fees, often per-megabyte. An eSIM for French Guiana is the only smart, cost-effective way to get data. Get connected the moment you land at Cayenne – Félix Eboué Airport (CAY).

Why Cellesim is Essential for Your Trip to French Guiana

Instant (CAY) Airport Connection: Get online the moment you land at (CAY) Airport. This is critical for coordinating transport or contacting your team in Kourou or Cayenne.
Massive Cost Savings: Our plans start at $5.29. This is a fraction of what you would pay for just a few megabytes of high-cost roaming.
Keep Your Home Number: Your eSIM handles the data, so your primary SIM (and your WhatsApp number) remains active for important calls and texts.
Premium 5G/4G Speed: As this is an EU territory, the infrastructure is strong. Connect to top-tier 5G/4G networks (like Orange Caraïbe) perfect for business needs.

Connect in French Guiana's Key Hubs

1. Kourou & The Guiana Space Centre

The heart of the European space program. An eSIM for Kourou is essential for engineers, technicians, and visitors needing stable, high-speed data for work and communication near the Space Centre.

2. Cayenne

The capital and main commercial hub. Your Cayenne eSIM keeps you connected for navigating the city, business meetings, and exploring the historic sites.

3. Saint-Laurent-du-Maroni

The historic border town near Suriname, known for the Transportation Camp. Stay connected even on the edge of the Amazon.

Frequently Asked Questions

Got some questions before your Journey? Well here's everything you need to know before you go

Yes. You will generally have strong signal on Île Royale and Saint-Joseph, allowing you to share photos of the historic prison ruins and the monkeys.

No, Uber does not operate in French Guiana. You need reliable data to find taxi stand locations on Google Maps or to call local radio taxis in Cayenne.

Signal is reliable at the main stops like Saint-Laurent-du-Maroni and Grand-Santi, but expect the connection to drop significantly while navigating the river between settlements.

Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing.

Yes. Coverage is excellent around the Space Centre and the Jupiter Control Centre in Kourou, allowing you to check launch schedules or live-stream rocket takeoffs.

Be very careful! As French Guiana is an overseas department of France, it is technically part of the EU, and "Roam Like at Home" (RLAH) should apply for EU citizens. However, most non-French EU carriers (e.g., from Germany, Spain, Italy) enforce strict "Fair Use Policies" for overseas territories, which can lead to high fees or throttled speeds. For UK (post-Brexit) or US travelers, it is definitely expensive international roaming. A Cellesim eSIM guarantees a fixed price and high-speed data.

It is limited to the coast. You will have excellent 4G/LTE/5G coverage in the main coastal towns: the capital Cayenne, Kourou (home of the Guiana Space Centre), and Saint-Laurent-du-Maroni. However, 90% of French Guiana is inaccessible Amazon rainforest. Once you travel inland (e.g., to Saül or Maripasoula), you should expect no signal. Download offline maps.

To give you the best speed, our eSIM connects to the premium French networks operating in the territory, typically Orange Caraïbe or SFR Caraïbe. This ensures you get high-quality, fast internet (not slow 3G) in all the main populated areas, just as you would expect in mainland France.

Yes, for mobility. While hotels in Cayenne and Kourou have decent Wi-Fi, it won't help you when you are on the road. Public transport is limited, so most visitors rent a car. An eSIM is essential for using Google Maps or Waze for navigation, finding restaurants, or using WhatsApp to coordinate tours.

This specific plan is valid only within French Guiana. This is a critical point. If you take a boat across the Maroni River to Suriname (Albina) or cross the Oyapock River Bridge to Brazil (Oiapoque), your connection will stop. For a seamless multi-country trip, we highly recommend our Latin America Regional eSIM plan.
