How do I know if my phone is compatible with an Indonesia eSIM?

Your phone must be carrier-unlocked and natively support eSIM technology, which includes iPhone XS and newer, as well as modern Android devices. You can check for an EID number in your phone's settings or by dialing *#06# to confirm compatibility. Compatible devices will seamlessly attach to top Indonesian networks like Telkomsel or Indosat.

How much data do I need for a trip to Indonesia?

For daily map navigation, ride-hailing apps like Grab, and social media posting, 1 GB to 2 GB per day is usually sufficient. If you plan to work remotely or stream video while exploring Bali or Jakarta, consider a 10 GB to 20 GB package. Most leisure travellers find a total of 10 GB ideal for a two-week trip.

When should I install my Indonesia eSIM?

We recommend installing the eSIM QR code onto your device prior to departure using your home Wi-Fi connection. Keep the eSIM line turned off until you physically land at an Indonesian airport. Once you arrive, switch on the eSIM data line and enable Data Roaming to gain immediate internet access.

Will my WhatsApp, Instagram, and iMessage still work in Indonesia?

Yes, all your social and messaging apps including WhatsApp, Instagram, and iMessage will work seamlessly. WhatsApp will automatically prompt you to retain your existing home phone number, so your chats and contacts remain unchanged. The eSIM simply supplies the high-speed Indonesian data needed to keep those apps connected.

Does this Indonesia eSIM include a local phone number?

Most travel eSIMs for Indonesia are data-only and do not come with a local (+62) phone number for standard calls or SMS. You can still make voice calls and send texts using internet-based apps like WhatsApp, FaceTime, or Skype. This completely avoids the complex real-name passport registration required for local physical SIM cards.

What should I do if my eSIM does not work upon arrival in Indonesia?

First, verify that your eSIM line is selected for Mobile Data and that Data Roaming is switched on in your settings. Next, toggle Airplane Mode on and off or restart your phone to force a connection to local partner networks like Telkomsel. If you still have no signal, manually select a supported network under your phone's Cellular settings.

Is an Indonesia eSIM cheaper than my home carrier's roaming plan?

Yes, an Indonesia eSIM is significantly cheaper than standard international roaming daily passes from home carriers, which can cost $10–$15 per day. Prepaid eSIM plans offer high-speed local data starting at a fraction of that cost for your entire trip duration. This helps you avoid unexpected bill shock while enjoying direct access to fast local network speeds.

Pack for humidity — cotton and quick-dry beats denim in Bali.

Staying connected in Indonesia

Telkomsel, Indosat and XL cover most of the country with 4G/5G. Grab an eSIM before you land — Bali's SIM kiosks queue quickly.
