Instabridge does not provide an Indonesia eSIM that includes a phone number or SMS capability. Only data‑only plans are offered for travelers going to Indonesia.
Because no voice or SMS services are included, users who want to keep in touch can rely on popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. Travelers should verify that these apps are accessible in Indonesia before making a purchase, as some destinations may block or restrict specific services.
