What can you do with your eSIM in Indonesia?

A travel eSIM handles your internet. See upfront what simply keeps working and what runs differently than on your normal SIM card.

This simply works

  • Use mobile data

    Your Indonesia eSIM handles all internet on your phone.

  • Use WhatsApp

    Your existing WhatsApp account and number keep working.

  • Call via WhatsApp or FaceTime

    These calls run over mobile data, so your Indonesia eSIM is enough.

  • Keep your own phone number

    Your regular SIM card stays active alongside the eSIM.

This works differently

  • Standard calls and SMS: Via your own SIM

    Most travel eSIMs are data-only.

  • Use as personal hotspot: Depends on bundle

    Hotspot support varies per bundle and provider. Check the details of the bundle you choose.

  • 4G in popular tourist hubs.
  • Essential for ride-hailing and travel apps.
