Network coverage in French Guiana
Orange is the dominant carrier in French Guiana, providing 4G LTE along the coastal strip where 95% of the population lives. Digicel operates primarily in the Caribbean islands and has limited presence here. Orange's French territory infrastructure delivers reliable speeds in Cayenne, Kourou, and Saint-Laurent-du-Maroni.
No other carrier offers eSIM-compatible service for international visitors. Orange is the go-to choice.
Coverage analysis
Orange 4G LTE covers the N1 coastal highway from Saint-Laurent-du-Maroni to Saint-Georges-de-l'Oyapock. Cayenne Félix Eboué Airport connects on arrival. The Guiana Space Centre in Kourou has full 4G coverage.
Inland waterways toward the Amazonian interior lose signal within 30-50 km of the coast. The territory is 90% rainforest with no mobile infrastructure. Travelers doing river tours into the Amazon should treat connectivity as unavailable once away from the coast.
Activation
Install your eSIM QR code before flying into Cayenne Félix Eboué Airport (CAY). Orange registers your eSIM within minutes of landing. No SIM card queue required.
French Guiana uses +594 country code and is in the UTC-3 time zone. iPhone XS or newer, Pixel 3a or newer, and Galaxy S20 or newer support eSIM. Your device must be carrier-unlocked. European visitors using French Orange plans may find their plan already covers French Guiana as an overseas territory.
Data usage tips
Budget 350-450 MB per day for maps, messaging, and travel logistics in Cayenne and Kourou. Download offline maps for coastal areas and note that the interior Amazon region has zero connectivity. Space Centre visitor programs involve guided tours; check the Arianespace website on Wi-Fi before your visit.
A 7-day plan covers a typical Guiana itinerary with visits to Cayenne, Kourou, and the coastal mangroves. Avoid relying on data for navigation once heading inland.
