Stellar eSim does not provide any eSIM plans with a local phone number or SMS capability for Gabon; only data‑only plans are available. Travelers who wish to make voice calls or send text messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may block or restrict certain apps, so it is advisable to verify that the services you rely on are accessible in Gabon before purchasing a plan.
