There are about 80 travel eSIM brands and roughly 2100 prepaid data plans available for use in French Guiana. With so many options, travelers have a wide variety of plans to choose from, making it easy to find an eSIM that fits their needs.
Available options for unlimited data eSIMs that cover French Guiana include Firsty, Roamify, Truely, Yesim, Yoho Mobile, and esimzon. These providers offer plans ranging from free or low‑cost to more premium packages, covering validity periods from single day to up to 30 days. Prices span from $0.00 USD for Firsty’s 1‑day ad‑supported plan to around $449.07 USD for certain Yoho Mobile packages. Most of these unlimited plans may involve throttling or explicit speed limits—for example, Firsty limits to 256 kbps, Yoho Mobile caps to 5 Mbps, and all providers state that speeds can be reduced during heavy usage. Travelers should consider expected data consumption and choose a plan that balances price with performance, especially if activities such as video streaming or large file transfers are planned.
In French Guiana, the primary Mobile Network Operators (MNOs) are:
These MNOs own and operate the infrastructure that supports mobile connectivity in the region.
Travel eSIMs that include a phone number and SMS capability are available for French Guiana from several providers. GlobaleSIM offers local‑style numbers with the dialing code +1 and supports inbound voice and SMS, although it does not provide outbound SMS. Amigo eSIM, SimOptions, MoreMins eSIM and Roamify supply numbers with dialing codes +44 (UK), +420 (Czech Republic) and +33 (France) and support both inbound and outbound voice and SMS. Because the international dialing codes above differ from French Guiana code, these numbers are not French Guiana‑specific.
Prices for the available plans start at about $4.50 USD for a 1GB 7 plan from GlobaleSIM and reach roughly $59.90 USD for a 120GB 30‑day plan from SimOptions; validity ranges from 7 to 35 days. All plans come with data, voice, and SMS coverage suitable for travelers visiting French Guiana.
