Data for Bali, Jakarta, Yogyakarta and the islands between, installed before you fly. Indonesia is on the Asia plan, so the same eSIM covers a stopover in Singapore or a week in Thailand on the way.
The Indonesia plan covers Indonesia only.
The same 10 GB in a package that keeps working past Indonesia.
20 other countries share the package with Indonesia. A few of them:
What's included, when it starts, and how to get connected.
Ngurah Rai is a small airport for the number of people who land at it, and the SIM counters in arrivals exist because most visitors turn up without data. You will walk past them.
Most visitors need a visa on arrival, which can be bought online in advance as an e-VOA to skip one queue; Bali also charges a separate tourist levy, payable online before you fly. Install your onesim eSIM over Wi-Fi and leave the line switched off.
After landing, open Settings → Mobile Data, select the onesim line for mobile data and turn data roaming on for that line only. Keep your home SIM in the phone with its roaming off; your own number stays reachable for bank and booking codes.
Fill in the electronic customs declaration online before you land and keep the QR code on the phone. Immigration is the slow part at peak hours — the e-VOA lane moves faster than the cash counter.
Order a Grab or Gojek from the app and walk to the marked pick-up area; the price is fixed in the app and far lower than the touts outside. A hotel transfer is the calmer option after a long flight. Kuta and Seminyak are twenty minutes; Ubud is an hour or more in traffic.
Bali’s roads are the single biggest risk of the trip. If you ride, you need an international driving permit with a motorcycle category, a helmet and travel insurance that actually covers it — most policies exclude riding without a licence. A car with a driver for a day costs less than a hospital visit and knows where the rice terraces are.
A hundred thousand rupiah is a few euros, so the notes look alarming. Cards are accepted in hotels, larger restaurants and shops; warungs, drivers and markets are cash. Use ATMs attached to banks rather than standalone machines, and refuse the machine’s own conversion rate.
The dry months are the best for beaches and volcano hikes; the wet season, November to March, brings short heavy downpours rather than washed-out days, and the island is green and cheaper. Nyepi, the Balinese day of silence in March, closes the airport and empties the streets for 24 hours — plan around it.
Temples lend or rent sarongs at the entrance and expect covered shoulders. Shoes come off in homes and many guesthouses. The small offerings on the pavement are stepped around, not over.
Answers about data, coverage and setup for Indonesia.
Yes. Indonesia’s IMEI registration rule applies to phones using an Indonesian SIM for more than a short visit; a travel eSIM connects through the local network as a roaming device, which is treated differently, and this is how onesim works everywhere. Install before you fly, switch the line on when you land, and the phone connects the way it would in any other country.
Yes — the package covers Indonesia, not just Bali, on the same networks. Coverage is strong in Bali, Jakarta, Yogyakarta and the other cities and towns, good along the main roads, and thinner on small islands, up the volcanoes and in the interior of the larger ones. On the Gilis expect it to slow at peak hours; download offline maps before a boat.
Yes. Both apps run on data; sign in before you fly, while your home SIM can still receive the verification text, and they work on the onesim line from the moment you land. The same goes for maps, WhatsApp and translation. Only the verification text needs your own number — which is why the home SIM stays in the phone with its roaming off.
