Is it worth getting an eSIM for Indonesia?
For most visitors, yes. An eSIM is the easiest way to stay online in Indonesia, installed before you fly and connected the moment you land, with no shops or paperwork.
Roaming on your home plan is usually expensive, often around $10 a day. A local Indonesian SIM is cheaper but means a shop visit, ID, and IMEI registration. An eSIM avoids both, with affordable local data from $4 with Ubigi and unlimited plans from Holafly.
For a week in Bali, a longer loop through Java and the islands, or a remote-work stint, an eSIM is the smarter choice for almost every visitor to Indonesia.
What is an eSIM?
An eSIM is a digital SIM card built into your phone that lets you activate a mobile plan without a physical card. You can install it before your flight by scanning a QR code or using a provider app, and your connection starts the moment you land.
Unlike a traditional SIM, there is nothing to swap or lose. Your data plan is stored directly on your device. Most recent phones support eSIMs, including any iPhone from XR and newer, Google Pixel 4 and later, and many Samsung and Xiaomi models.
In Indonesia, eSIMs connect to the country's mobile networks and deliver fast data across the main islands and tourist areas, a simple, reliable way to stay online without visiting a store or registering a local SIM.
Is eSIM available in Indonesia?
Yes. Indonesia fully supports eSIM technology for travellers. You can install an eSIM from international providers like Ubigi and Holafly before you arrive, and your phone connects automatically to a partner network when you land. Indonesia's main carriers, Telkomsel, Indosat Ooredoo, and XL Axiata, all run extensive 4G networks, with 5G live in the main cities and tourist areas.
As long as your phone is unlocked and eSIM-compatible, you can install your plan before your flight and activate it the moment you reach the airport in Jakarta, Bali, or beyond.
Is an eSIM or a local SIM card better for Indonesia?
An eSIM is usually better for Indonesia because it is faster to set up and works the moment you arrive. You can install it before your flight and skip the store visit, ID check, and IMEI registration that a local SIM requires.
A local Indonesian SIM can suit very long-term stays, but the in-person registration and sometimes unclear pricing make it rarely worth it for a short or medium trip. For most visitors, an eSIM is simpler, faster, and online before you land.
Both of our recommended providers, Ubigi and Holafly, connect to Indonesia's major networks, giving you reliable data across the country without the hassle of a local SIM.
Mobile networks in Indonesia: which one matters for your trip?
Indonesia is served by its main mobile networks, and the one your eSIM connects to affects the coverage you get, especially on the smaller islands and in rural areas.
Telkomsel has the widest and most reliable coverage in Indonesia, with the strongest reach across Java, Bali, the outer islands, and rural areas.
Indosat Ooredoo offers strong, fast coverage across the main cities and tourist areas, competitive in the urban centres.
XL Axiata provides solid coverage in the cities and along the main routes of Java and Bali.
Which network matters for your eSIM choice
- If your trip focuses on Jakarta, Bali, and the main cities, every network delivers excellent connectivity.
- If you are heading to Lombok, the Gili Islands, Flores, or remote areas, Telkomsel has the broadest reach.
- Expect strong coverage in the tourist hubs but the odd gap on remote beaches, dive boats, and in the hills.
Both Ubigi and Holafly connect to Indonesia's leading networks for reliable data, so you get solid coverage whichever you choose. You can check current plans on the Ubigi and Holafly sites.

Lombok, the Gilis and beyond
The nearby islands have workable coverage around the main villages and beaches, strongest on Telkomsel, easing off on quieter stretches and boat crossings. Download offline maps before island day trips.
How to choose the right eSIM for Indonesia
Choosing the right eSIM for Indonesia depends on how you travel and how you use your data. Start by checking that your phone supports eSIMs, then look at plans based on data, duration, and support.
Here is what to consider before buying your Indonesia eSIM:
- Phone compatibility: Most iPhones from XR and newer, Google Pixel 4 and later, and many Samsung and Xiaomi models support eSIMs.
- Data usage: Light users can stay connected with a few GB, while remote workers or streamers may prefer a 25GB or unlimited plan.
- Trip length: Ubigi is great for both short trips and longer stays with flexible top-ups, while Holafly's by-duration unlimited plans suit anyone who would rather not track usage.
- Where you are going: For Lombok, the Gilis, and remote islands, prioritise coverage on Telkomsel.
- Support options: Pick a provider with reliable support if you want help activating your plan; Holafly offers 24/7 chat.
How to set up your eSIM in Indonesia
Setting up an eSIM in Indonesia is quick and can be done entirely online. You can install it before your flight and activate the plan as soon as you arrive.
Step by step eSIM setup guide:
- Check compatibility: Make sure your phone supports eSIMs and is unlocked. Most recent iPhones, Google Pixel, and Samsung models are compatible.
- Choose a provider: Pick a trusted option that fits your data needs, such as Ubigi or Holafly.
- Buy your plan: Select your data package or duration online and complete the purchase.
- Install your eSIM: You will receive a QR code or app link. Scan it or follow the in-app setup instructions.
- Activate your plan: Turn on mobile data and select the new eSIM as your active plan once you land in Indonesia.
- Test your connection: Open a browser or map app to confirm you are online before leaving the airport Wi-Fi.
Most travellers complete the process in under five minutes. If anything goes wrong, both Ubigi and Holafly offer support to help you get connected.
A note on IMEI registration in Indonesia
Indonesia requires locally bought SIM cards to have the device's IMEI registered with the telecom authority. The good news for travellers: roaming eSIMs like Ubigi and Holafly are not affected for short and medium stays, because your phone connects as a roaming device rather than a local subscriber. If you stay longer than 60 days, your device's temporary IMEI permit can expire and local data may become restricted; in that case you can register your device at an Indonesian customs office or authorised service centre. For most travellers on shorter trips, no extra steps are needed.
Travel tip for Indonesia
Staying connected is just one part of a smooth trip. If you are planning a longer stay or island-hopping, make sure you are covered with reliable travel insurance too. See our guide to the best travel insurance for digital nomads for coverage details.
Final recommendation: which eSIM is best for Indonesia?
Both Ubigi and Holafly are reliable choices for staying connected across Indonesia. The best option depends on your travel style and data needs.
