What is an eSIM, and how does it work in Indonesia?
An eSIM (embedded SIM) is a built-in chip inside your phone that can be programmed with a mobile data plan. Instead of inserting a physical SIM card, your device downloads a digital profile provided by the eSIM provider. This profile contains the necessary network settings, authentication keys, and routing information your phone needs to connect to a mobile operator.
When you install an eSIM for Indonesia, your device creates a secure link with the provider’s partner network, typically Indosat Ooredoo (Ubigi) or Telkomsel (eSIM4Travel). Your phone uses the details stored on the eSIM profile to authenticate itself on the local network, similar to how a physical SIM identifies you to a carrier.
Once activation is complete, your device automatically selects the supported Indonesian network when you arrive in the country. All connectivity parameters, such as APN settings, roaming permissions, and data routing, are handled digitally through the eSIM profile, so you don’t need to configure anything manually.
Because everything happens on the chip already inside your phone, switching between providers, adding new plans, or storing multiple profiles becomes a simple software process rather than a physical SIM swap.
What’s better for Indonesia: an eSIM or a local SIM card?
eSIMs are a practical choice for travellers who want to be connected as soon as they arrive in Indonesia. You can purchase and install your plan before your trip, skip in-person registration, and activate the connection the moment your plane lands. International eSIMs typically use partner networks such as Indosat Ooredoo or Telkomsel, which ensures strong coverage across major cities including Jakarta, Surabaya, Bandung, and Yogyakarta.
Local SIM cards can be cheaper for extended stays, but they come with extra steps. Indonesian SIMs require in-person registration with your passport, and some providers may ask for additional verification depending on the outlet. Queues, limited store hours, and airport pricing mark-ups can make the process time-consuming for new arrivals.
For most short- and medium-term visitors, eSIMs are the more convenient option. They save time, avoid paperwork, and provide reliable connectivity without the need to visit a store.

How to choose the right eSIM for Indonesia
Choosing the right eSIM for Indonesia depends on your data habits, the length of your trip, and where in the country you plan to spend most of your time. Here are a few things to keep in mind:
- Check your data needs: Light users who mainly rely on maps, messaging apps, and quick searches can choose a smaller data plan. If you expect to do video calls, tethering, or anything data-intensive, a larger package will be more reliable.
- Consider your trip duration: Short stays work well with small fixed plans or short-validity options. For longer trips, look for 15–30 day plans or higher data limits so you don’t run out midway through your stay.
- Verify device compatibility: Most newer smartphones support eSIM, including recent iPhone, Pixel, and Samsung models. Always confirm in your device settings under Mobile Network or SIM Manager before buying.
- Think about the regions you’ll visit: Coverage is strong in major cities like Jakarta, Surabaya, Bandung, and Yogyakarta. If you’ll be travelling through quieter regions or areas with limited Wi-Fi, choosing a plan with more data gives you a better buffer on the ground.
- Check setup guidance and support: Pick a provider with clear installation steps and accessible customer support. This helps if you run into issues during activation or while switching between networks.
Taking a moment to compare plans before your trip makes it easier to choose an option that fits your travel style and keeps you connected throughout Indonesia.
How to set up your eSIM for Indonesia
Setting up your eSIM is straightforward and works best if you install it before your trip. Most providers send you a QR code or setup link immediately after purchase, along with simple step-by-step instructions.

- Test your connection: Open a browser or map app to check that mobile data is working before leaving the airport or your accommodation.
