GulfData does not currently offer any eSIM plans for Chad that include a phone number or SMS capability. Existing plans from this provider are data‑only; travelers can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, but they will not be able to receive phone calls or SMS through the eSIM. Because some destinations restrict certain apps or VoIP services, it is advisable to confirm that the services you rely on are accessible while in Chad before purchasing a data‑only plan.
