Yes, if you are in the official viewing zone. Orange Caraïbe has dedicated 4G infrastructure for launch events, and you will get enough speed to upload photos and stream video. Public viewing areas 10 kilometers away have weaker 3G signal, and Digicel coverage thins past Kourou town center. Download offline maps and pre-cache any files before heading to the site.

Only on Île Royale, and only intermittent 3G from Orange. Devil's Island and Île Saint-Joseph have no coverage from any carrier. The ferry crossing has no signal either, so plan offline entertainment and download any maps or guides before you leave Kourou.

No. Cellular service from Orange and Digicel ends past Saül and Maripasoula. The interior rainforest has zero coverage from any carrier — guides and expeditions carry satellite phones as standard. If you are driving or boating inland, expect to lose signal within 30 minutes of leaving the coastal highway.

Three to five gigabytes covers maps, WhatsApp, email, and social media for a typical week. If you are uploading launch photos or video calling home daily, budget seven to ten gigabytes. Streaming a rocket launch live can consume 500 MB to 1 GB depending on resolution, so factor that in if you are visiting during a launch window.

Yes. WhatsApp voice and video calls work on Orange and Digicel's 4G networks in Cayenne, Kourou, and Saint-Laurent. Quality is better than the local PSTN in most coastal areas. Expect calls to drop if you are on the Maroni River or in the rainforest interior where cellular service disappears.

Both carriers offer LTE in Saint-Laurent's town center, but Orange has better coverage on the RN1 highway approaching from Cayenne. Digicel's signal thins faster on the Maroni River routes. If you are crossing into Suriname or taking a boat upriver, expect to lose service from both carriers within 15 minutes of leaving the dock.

No. Uber does not operate in French Guiana. Taxis are the main option in Cayenne and Kourou, and you will find them at the airport, hotels, and the Space Centre. Some drivers accept WhatsApp for booking, so the eSIM's data is useful for coordinating pickups.

Yes. Orange Caraïbe has continuous 4G coverage along the RN1 from Cayenne to Saint-Laurent-du-Maroni. Digicel's coverage is spottier but present in most towns along the route. Side roads into the rainforest lose signal quickly — download offline maps before turning off the highway.

The Orange Caraïbe shop at Cayenne-Rochambeau airport sells physical SIMs for around €20, and you will need to show your passport and fill out a registration form. The eSIM activates the same Orange network remotely before you land, skips the paperwork, and costs less for short trips. Both give you the same 4G coverage across the coast.

Yes. Hotspot is enabled by default, so you can tether a laptop, tablet, or a travel companion's phone. No extra fee, no throttle on the first several gigabytes. Useful if you are filing work from Cayenne or sharing data with someone whose device does not support eSIM.

Yes, and you should. Download the Cayenne, Kourou, and Saint-Laurent map areas before leaving the coast. Cellular service ends abruptly past Saül, and the interior has no coverage from any carrier. Offline maps are the only navigation option once you leave the RN1 highway.

Yes. Rain does not affect Orange or Digicel's 4G networks in Cayenne, Kourou, or Saint-Laurent. Heavy storms can slow speeds slightly, but you will still get enough bandwidth for maps and messaging. The bigger issue is road access — some interior routes flood and close during the wettest months, but that is a logistics problem, not a connectivity one.

Under two minutes if you install the profile before your flight. If you wait until you land, scan the QR code in the arrivals hall and the eSIM registers on Orange or Digicel within 60 seconds. You will see the carrier name and signal bars appear, and data works immediately.
