Billion Connect does not currently offer a Timor‑Leste eSIM with a phone number or SMS capability. The provider only sells data‑only eSIM plans for travel in Timor‑Leste.
Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict certain apps or services, so passengers should confirm that the specific apps they rely on work in Timor‑Leste before buying a plan.
