Yesim eSIM Data Plans for French Guiana

Yesim offers unlimited data eSIM plans for French Guiana that can be purchased for 1 day, 7 days, 15 days, or 30 days. The 1‑day plan costs $8.17, the 7‑day plan $25.69, the 15‑day plan $40.87, and the 30‑day plan $57.21; there is also a 30‑day global package that includes French Guiana for $75.90. All unlimited plans use 3G or LTE networks and allow tethering, but the speed may be throttled after heavy usage under a Fair Usage Policy. Users who need to ensure consistent high‑speed access are advised to contact Yesim to confirm whether the Fair Usage Policy applies and to learn the typical amount of data that remains available at normal speed.

Yesim does not provide any eSIM plan for French Guiana that includes a phone number or SMS capability. The available plans are data‑only plans. Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and message services.

Yesim provides 8 single‑country plans and 13 multi‑country plans that include French Guiana. Prices span from about $0.53 to $127.27 USD, while data caps range from a modest 105 MB to unlimited. The single‑country options offer a fixed data amount allocated for the plan’s validity period, whereas the multi‑country packages let you use the same data across several destinations, often with daily data limits rather than a single top‑up amount. Both types typically allow tethering unless a plan specifies otherwise.
