For many travellers, Bali is the highlight of a long-haul trip: the rice terraces of Ubud, surfing in Canggu, sunsets in Seminyak. And with a bit more time, Java, Lombok or the Gili Islands get added to the route. Indonesia, however, is far outside the EU, so your bundle from home won't work there without sky-high roaming charges. An eSIM for Indonesia is installed before you leave, so you're online the moment you land in Denpasar.
Why you can't do Bali without data
Bali arguably runs on mobile internet even more than home does:
- Gojek and Grab. The apps for rides, scooters and food delivery. No data, no ride, it's that simple.
- Scooter navigation. Most travellers rent a scooter, and the small roads between the rice fields are only findable with Maps in your handlebar mount.
- WhatsApp with everyone. Your driver, your homestay, the warung around the corner: in Bali, every arrangement happens over WhatsApp.
- Booking boats and tickets. The fast boat to the Gilis or Nusa Penida is booked online, just like entry tickets for temples and waterfalls.
- Working remotely. There's a reason Bali is one of the most popular digital nomad bases in the world.
In the tourist areas, all of this works flawlessly. In Canggu, Ubud, Seminyak and Uluwatu the network is fast and you'll rarely be without signal.
Coverage beyond the tourist hubs
Indonesia is enormous: more than 17,000 islands. Coverage varies accordingly. Good to know: of the local networks, Telkomsel has by far the strongest coverage outside the tourist hubs. Pick an eSIM that runs on that network and you'll have signal most often on Lombok, on Java and up in the hills too.
In genuinely remote spots, like small islands, volcano slopes and inland areas, the signal can still drop. There's a simple fix: download offline maps of your route before you set off. Navigation keeps working, even without coverage.
Local SIM card or eSIM?
Buying a local SIM card in Bali is possible, but it's more hassle than you'd expect. At the airport you pay tourist prices, at roadside stalls you need to make sure the card is properly registered (passport registration is mandatory in Indonesia), and meanwhile your own SIM is somewhere at the bottom of your backpack while your bank tries to send you a verification text.
With an eSIM you skip all of that:
- Order your bundle and compare the eSIM bundles for Indonesia, so you get the cheapest one for your trip length.
- Scan the QR code from your email at home. Five minutes of work.
- Turn on data roaming for your eSIM profile when you arrive, and you're online before you reach the taxi rank.
Your own SIM stays in your phone, so you remain reachable on your regular number for texts and WhatsApp.
How much data for Indonesia?
Trips to Indonesia are rarely short. Plan generously:
| Trip | Estimated usage |
|---|---|
| 2 weeks Bali | 8-12 GB |
| 3-4 weeks Bali + Lombok or Java | 15-25 GB |
| Longer stay or remote work | unlimited |
Lots of scooter navigation, photo sharing and the occasional video call home: it adds up, especially since guesthouse wifi is hit and miss. Use the data calculator to work it out precisely for your trip.

FAQ
Does the eSIM work on the Gili Islands and Nusa Penida? Yes, the inhabited islands around Bali generally have decent coverage. On the boat in between, the signal may drop for a while.
Can I share the eSIM with my travel companion? Yes, through your phone's hotspot. Sharing one bigger bundle is often cheaper than buying two separate ones.
What if I run out of data? Our bundles are prepaid: when it's gone it's gone, no surprises afterwards. Topping up or ordering a fresh bundle only takes a few minutes.
Any settings needed if the internet doesn't work?
Usually turning on data roaming is enough. If it still doesn't work, check that the APN is set to data.esim.
Conclusion
Indonesia and Bali are destinations where your phone is part of everything you do: Gojek, scooter navigation, WhatsApp with your homestay. The network is solid in the tourist areas, and with the right eSIM you'll have signal beyond them more often than not. Arrange it before departure and you're online from the moment you land.
