Prices are live and may change. Google Fi is excluded from the value ranking because it is a full phone plan rather than a travel data plan.
Cayenne
- Arriving
- Félix Eboué Airport (CAY) is about 13 km from the centre; transfers are by taxi or bus. The airport has 4G from Orange and Digicel. As a French department, EU roaming should technically apply, but not all European plans include French Guiana, so verify your coverage before relying on it.
- On the subway and rail
- Cayenne moves by buses and taxis; the centre around the Place des Palmistes is walkable. There is no metro or rail. Coverage holds across the capital and the coastal road. The vast interior rainforest beyond the coastal strip has effectively no signal.
- Free public WiFi
- Cafes, hotels and the Place des Palmistes area provide WiFi. CAY airport has terminal WiFi. Connectivity is easy along the coast, a supplement to the cellular data.
- Coverage in the city
- Orange and Digicel run 4G across Cayenne, the Place des Palmistes, the market and the coastal corridor, with Orange the stronger along the coast. As a French/EU territory EU roaming should apply, though coverage varies by plan. The interior rainforest, over 90% of the territory, is offline.
- If you prefer a local SIM
- Orange and Digicel sell SIMs in Cayenne. Confirm whether your European eSIM actually includes French Guiana, as many exclude overseas departments; otherwise a local Orange SIM is the reliable option along the coast.
Kourou
- Arriving
- Félix Eboué Airport (CAY) near Cayenne is about 60 km away; transfers are by bus or taxi. Kourou is home to the Guiana Space Centre, Europe's spaceport. The town has 4G from Orange and Digicel. As elsewhere in the department, verify your EU plan covers French Guiana before relying on it.
- On the subway and rail
- Kourou moves by buses and taxis, with boats out to the Salvation Islands (ÃŽles du Salut); the town is walkable. There is no metro or rail. Coverage holds across the town and the Space Centre. The boat trips to the islands hold signal close to Kourou.
- Free public WiFi
- Hotels and the Guiana Space Centre visitor areas provide WiFi. Connectivity is easy in the town, with a working SIM or eSIM covering the launch-viewing areas and the island boat trips.
- Coverage in the city
- Orange and Digicel cover Kourou, the Guiana Space Centre and the Ariane and Vega launch-viewing areas. The Salvation Islands (ÃŽle Royale and the former penal colony of Devil's Island) have basic coverage, with the boat ride out holding signal close to shore. The interior beyond is offline.
- If you prefer a local SIM
- Orange and Digicel sell SIMs in Kourou and Cayenne. Confirm your European eSIM covers French Guiana specifically, as overseas departments are often excluded; a local Orange SIM is the dependable choice for the coastal strip.
Grab an eSIM before you arrive in French Guiana to skip local SIM queues. Most urban areas offer 4G or better, while rural regions can slow down, so keep offline maps handy. Activating the eSIM in advance ensures you are connected the moment you clear customs.
French Guiana is a French overseas department on the northeast coast of South America. Orange and Digicel provide 4G LTE in Cayenne, Kourou (home of the European Space Center), and along the coastal road. As a French territory and part of the EU, EU roaming regulations technically apply, though not all European eSIM plans include French Guiana in practice.
The vast interior rainforest - which covers over 90% of the territory - has virtually no cellular coverage. The Maroni and Oyapock river communities accessible only by boat are largely offline. For travelers visiting the Space Center in Kourou, the Salvation Islands, or exploring Cayenne, connectivity will be functional. Beyond the coastal strip, prepare for complete disconnection.
- Check if your European eSIM plan actually covers French Guiana - many exclude overseas departments
- Cayenne and Kourou have reliable coverage along the coast
- The interior rainforest has no cellular coverage - download everything before going inland
- Orange has better coverage along the coastal corridor
- EU roaming should apply but verify with your specific provider

- 1
Buy and install at home on WiFi.
Installation is not the same as activation. You can install the French Guiana eSIM days ahead and only switch it on after you land, which avoids burning days of validity in transit.
- 2
Screenshot your current APN before you swap.
If you ever need to switch back to your home line quickly, that screenshot saves a support call from a foreign airport.
- 3
Decide on your dual-SIM strategy.
Keep your home line on for SMS-based bank logins, two-factor codes, and emergency calls. Set the travel eSIM as the data line only. Most modern phones can do both simultaneously.
- 4
Disable iMessage on the travel eSIM line.
Otherwise iMessage will try to re-activate against the new line on arrival and you will spend the first ten minutes troubleshooting it instead of finding the taxi rank.
- 5
Download offline maps for French Guiana.
Google Maps and Apple Maps both support offline regions. Pull them down on home WiFi so a flaky activation never leaves you without a route from the airport. Our offline maps guide walks through it step by step.
- 6
Activate at the airport, not before.
Once the validity timer starts it does not pause. A 15-day plan you turn on the morning of departure burns a full day of validity before you even land.
We are building this section from real, verified traveler submissions rather than stock testimonials, so it stays empty until we have notes we can stand behind. If you have used an eSIM in French Guiana recently, a one-paragraph note on what worked (and what did not) helps the next traveler.
