ByteSIM does not provide an eSIM plan with a local phone number or SMS capability for Chad. The provider offers only data‑only eSIMs in that country, so callers cannot make or receive voice calls or SMS directly through the local SIM. Travelers who need voice or messaging can still use the data connection for VoIP applications such as WhatsApp, Telegram or iMessage; however, some destinations may block certain services, so it is advisable to confirm that the applications a traveler relies on work in Chad before purchasing.
