Airalo currently offers only data‑only eSIM plans for Chad, and there are no plans that provide a phone number or SMS capability. Travelers who need voice or text can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may block or restrict access to certain apps or VoIP services, so users should confirm that the apps they need are available in Chad before purchasing an eSIM.
