French Guiana eSIM

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. 

Planning the trip? See our French Guiana eSIM plans, install in one tap before you fly, and land online. Free VPN included.

 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. 

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. 

 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. 

 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. 

Look up your phone’s exact model number with the manufacturer to see if it’s listed as compatible, and make sure your phone is not carrier-locked. Seeing an EID number or an “Add eSIM” option in your settings is a good sign, but some phones have regional restrictions. If you’re not sure, please contact our support team before you buy.
