MobiMatter eSIM Data Plans for French Guiana

MobiMatter does not provide an unlimited data eSIM for French Guiana. The plans that it sells for this destination are fixed‑data offers, each with a hard cap: the Best World 25GB 90 Days plan supplies 25GB for 90 days, while the LatAm 20GB and Caribbean 20GB plans each give 20GB for 30 days, and the Discover Global 10GB and LatAm 10GB plans provide 10GB for 30 days.
These fixed data plans can be more cost‑effective for most travelers; however, if a user requires a very large amount of data, a larger cap plan such as the 25GB 90‑day option may be preferable, and additional data can be purchased later if needed.

MobiMatter does not currently offer any French Guiana eSIM plans that include a phone number or SMS capability. All available eSIMs from this provider for French Guiana are data‑only.

Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict specific apps or services, so it is advisable to confirm the accessibility of the apps you depend on in French Guiana before buying a plan.

MobiMatter provides 16 multi‑country data plans that include coverage in French Guiana. The available offers range in price from about $4.99 to $81.99 and provide between 1 GB and 25 GB of data, valid for durations from 7 to 90 days. Many of these plans also permit tethering across connected devices.
