Voyasim does not provide French Guiana eSIM plans that include a local phone number or SMS capability. Only data‑only eSIMs are offered for the territory, allowing high‑speed internet access but no local voice calls or text messaging.
Travelers who need to communicate while in French Guiana can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or limit access to these services, so it is advisable to check that the apps you rely on are available in French Guiana before purchasing a data‑only eSIM.
