Everything you need to know about using eSIMs in French Guiana
There are more than 130 travel eSIM providers and more than 4 500 prepaid data plans for French Guiana, giving travelers a wide variety of options to choose from and making it easy to find an eSIM that fits their needs.
Yes, there are unlimited data eSIM options available for travel in French Guiana. Several providers—including Roamify, Yesim and Truely—offer plans that allow you to use data without a pre‑set network cap, with validity periods ranging from one to thirty days. These plans support tethering, but the data speed can be reduced or throttled after a certain amount of usage, so the “unlimited” allowance does not guarantee consistent high‑speed connectivity at all times.
The pricing for these unlimited plans varies between approximately four and a half dollars and one hundred and fifty‑five dollars in US currency, with Roamify’s range spanning $4.50 to $155.00, Yesim’s from $5.11 to $115.06 and Truely’s from $5.52 to $98.90. Travelers should review the individual provider details to balance cost against the expected data needs for activities such as streaming, navigation, and regular internet use while abroad.
