Stellar eSim does not provide an eSIM plan for French Guiana that includes a local phone number or SMS capability. Only data‑only eSIMs are offered for this destination. Travelers can still use Voice over Internet Protocol apps such as WhatsApp, Telegram, and iMessage over the data connection for calls and messages, although some destinations may block or restrict certain VoIP services, so users should verify that the apps they need will work in French Guiana before purchasing.
