eSIM French Guiana: prepaid data on Bouygues / DigiCel for Cayenne, Kourou and the rainforest
French Guiana is a corner of South America that runs on euros and French road signs, and most trips start in Cayenne before heading to the space center at Kourou, the Îles du Salut, or a river lodge deep in the forest. Do not assume your home bundle treats this overseas department like mainland France; many travelers arrive to find roaming either excluded or expensive. A French Guiana eSIM from GlobaleSIM is bought online, installed before you fly and connects automatically on arrival, while your own number keeps working on your primary SIM.
Networks and coverage in French Guiana
The eSIM French Guiana plan connects through Bouygues / DigiCel, the partner network for the territory. Coverage is good in Cayenne, Kourou, Saint-Laurent-du-Maroni and along the coastal road that links them, which is where the great majority of visitors spend their time. Once you head inland toward the Maroni or Oyapock rivers, or into the interior forest, reception thins out quickly and disappears in many areas. That is true of every operator here, so treat the eSIM as your coastal connection and download maps and documents before any jungle or river excursion.
Llamadas y un número de teléfono
Data alone covers WhatsApp, video calls and messaging. Add a voice-minutes bundle (+100, +200 or +300 minutes) and your eSIM also gets a dedicated international phone number, US +1 or UK +44, for calls and SMS. In French Guiana that is useful for reaching a lodge that does not answer messages, confirming a launch-viewing reservation at the space center, calling a car-rental desk in Cayenne, or receiving verification codes from your bank. Calls are not part of the data-only plan.
Plans, prices and validity
The French Guiana prepaid data plan starts from $4.5 for 1GB, with 2GB, 3GB, 5GB, 10GB, 15GB and 20GB plans available. Validity runs 7 days for 1GB, 10 days for 2GB, 14 days for 3GB, 21 days for 5GB and 30 days for 10GB, 15GB and 20GB. A short visit built around Cayenne and Kourou is well served by 2GB or 3GB; a longer stay, a work assignment or a family sharing one hotspot should go for 10GB or more. The validity clock starts only when the eSIM first connects in French Guiana, so installing days ahead loses nothing.

Tips for mobile data in French Guiana
Distances between towns are long and public transport is thin, so most visitors rent a car and rely on navigation apps; keep an offline map as backup for the stretches with no signal. Wi-Fi at hotels in Cayenne and Kourou is generally available but not always reliable, and in forest lodges it is often absent entirely. Rocket launches at Kourou draw crowds and the network gets busy, so download tickets and confirmations in advance. Card payments are the norm in towns, but smaller river operators may prefer cash.
