GigSky does not offer a Gabon eSIM plan that includes a phone number or SMS capability. Only data‑only eSIMs are available for Gabon.
Travelers who need voice or messaging can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should confirm that these services are accessible in Gabon before purchasing, as some destinations may block or restrict specific apps or VoIP services.
