Billion Connect does not provide an eSIM plan for Indonesia that includes a phone number or SMS capability. Their offers for this destination are data‑only plans, so travelers will not receive an active local number for voice calls or standard text messaging. However, they can still use WhatsApp, Telegram, iMessage, and other VoIP applications over the data connection, provided those services are not blocked or restricted in Indonesia. Travelers should confirm that the specific messaging or calling apps they rely on work in the country before purchasing a plan.
