Kolet does not provide an eSIM for French Guiana that includes a phone number or SMS capability. The only plans available from Kolet for this destination are data‑only packages, so travelers will not receive inbound or outbound voice or SMS services.
If a traveler needs to make voice calls or send messages, they will need to rely on VoIP applications such as WhatsApp, Telegram or iMessage over the data connection. However, accessibility of these services can vary; some destinations may block or restrict specific apps or VoIP services, so it is advisable to check that the applications you plan to use are accessible in French Guiana before purchasing a Kolet eSIM.
