Simsima eSIM Data Plans for French Guiana

Simsima does not provide a truly unlimited data eSIM for French Guiana. The only plan that carries the word “Unlimited” offers 3GB of high‑speed data per day and reduces the speed to 1000kbps after that amount is used, so it is not an unlimited plan.

Travelers who need more data can choose from Simsima’s fixed data plans. For example, a 20GB plan valid for 30 days or a 10GB plan valid for 30 days are available for French Guiana. These fixed data plans can be more cost‑effective for most users, unless a traveler expects to consume data well beyond the plan’s allowance.

Simsima does not provide eSIM plans with a local phone number or SMS capability for French Guiana. Travelers who purchase a Simsima eSIM for this destination will receive only data access, and can use VoIP applications such as WhatsApp, Telegram and iMessage over the data connection for voice and text communication. Because some destinations may block or restrict certain VoIP services, travelers should verify that the apps they rely on function in French Guiana before purchasing a plan.

Simsima provides 10 single‑country plans and 13 multi‑country plans that cover French Guiana. The available options span a price range of $4.16 to $84.83 and data caps from 1 GB to 20 GB, with validity periods lasting between 5 and 365 days. Among these plans, five are structured with daily data caps while the remaining eighteen offer fixed data amounts, giving travelers flexibility depending on whether they prefer a steady daily allowance or a larger, one‑time data bundle.
