Essential information to help you get connected seamlessly
This virtual SIM only includes data. It does not allow you to make cell phone calls or send SMS messages. You can still use WhatsApp or Skype to call your contacts.
Make sure your phone is both unlocked and compatible with eSIM technology.
Scan the QR code from your smartphone settings and add the data plan. You can either print it and scan it, or open it on another device to scan it. But don't activate it until you land at your destination.
A visa on arrival, a Bali levy paid on one real site, an arrival declaration to file, and rides by app
Indonesia has a few boxes to tick before and at the border, and it is worth knowing them so none of them surprises you. Most visitors take a visa on arrival, everyone now files a single electronic arrival declaration, and if Bali is on your route there is a separate tourism levy to pay, on one official site only. Once you are in, a ride-hailing app replaces the fare haggle and a stack of rupiah covers the rest. This guide covers the visa, the declaration, the Bali levy, getting around, and why data matters across the islands.
Borobudur, the great Buddhist monument
Borobudur in Central Java is the world's largest Buddhist temple, a ninth-century terraced monument that Indonesia's tourism board lists among its signature sights, often visited early for the light over the surrounding volcanoes. Access to the upper terraces is managed to protect the stone, so it is worth checking the current ticket and access rules before you go rather than assuming you can wander freely.4
Our take: pair Borobudur with the Hindu temples at Prambanan nearby and base in Yogyakarta between them. A single day can cover both if you start at dawn and treat the afternoon heat as rest time.
Ride-hailing apps replace the fare haggle
In the cities and across Bali, ride-hailing apps are the simplest way to get around, offering both cars and motorbike taxis at a price set in the app rather than negotiated at the roadside. They also handle food delivery and small errands, so one app covers much of a day's logistics without needing cash or local-language haggling.4
Our take: use an app for point-to-point rides while you learn the going rates, and take the motorbike-taxi option for short hops through traffic. On Bali, factor in that popular routes clog badly at peak hours, so plan around them rather than through them.
The currency is the rupiah, and cash still matters
Prices are in Indonesian rupiah (IDR), a currency with many zeros, so check you are reading the right number of them. Cards and app payments work in hotels, malls and chains, but warungs, markets and small towns run largely on cash, so carry small notes and do not rely on cards away from the tourist centres.4
Most visitors take a visa on arrival
Citizens of a long list of countries can enter Indonesia on a visa on arrival, a single-entry visa valid for 30 days and extendable once for another 30, for a fee of IDR 500,000. You can buy it at the airport counter or apply online in advance through the official Directorate General of Immigration, which saves queuing on landing.1
Everyone files one electronic arrival declaration
Indonesia now uses a single integrated arrival declaration, the All Indonesia system, which replaced the separate electronic customs form for international arrivals. You complete it online in the days before you land, and it is required of all travellers, so file it alongside your visa rather than at the airport.3
Bali charges a IDR 150,000 tourism levy, on one real site
If your trip includes Bali, every foreign visitor pays a one-off tourism levy of IDR 150,000, charged once per trip rather than per entry. The only legitimate place to pay is the Bali provincial government's official Love Bali site; lookalike .com pages and QR codes handed to you are scams, so pay on the official portal and keep the QR voucher.2
112 is the national emergency number
Indonesia's national emergency line is 112, reachable free from any phone in areas where it operates, connecting to police, ambulance and fire. Coverage of the service varies by region, so in a tourist area your accommodation is often the fastest route to the right local help.
Indonesia sits outside every regional free-roaming zone, so a home plan roams here at a charge whatever your country, and a local eSIM keeps data at a predictable and generally low price, since Indonesian mobile data is cheap. Coverage is strong across Bali, Jakarta and the main tourist and city areas, and thins on the smaller islands, at sea between them and in the remoter interior, which is exactly where a downloaded map earns its place. You will use data from the moment you plan the trip: the visa on arrival, the All Indonesia arrival declaration and, for Bali, the tourism levy are all online, and once you land, ride-hailing, maps and translation run the day. Because so much moves through an app, from the ride you book to the levy you show at a checkpoint, a working connection is what keeps an Indonesia trip smooth. Get connected on arrival rather than later, since your first tasks are usually a map and a ride from the airport.
Most visitors use a visa on arrival: a single-entry visa valid for 30 days, extendable once for another 30, costing IDR 500,000. Citizens of a long list of countries are eligible, and you can either buy it at the airport or apply online in advance through the official Directorate General of Immigration. Check the official list for your nationality before you travel.1
If your trip includes Bali, every foreign visitor pays a one-off IDR 150,000 tourism levy, charged once per trip. Pay it only on the Bali provincial government's official Love Bali portal, because lookalike sites and QR codes handed to you in person are scams. Save the QR voucher you receive, as you may be asked to show it.2
Yes. Indonesia now uses a single electronic arrival declaration, the All Indonesia system, which replaced the older separate customs form. It is required of all international arrivals, and you complete it online in the days before you land, so do it in advance alongside your visa.3
Usually not. Indonesia is outside every regional free-roaming arrangement, so roaming on a home plan is billed whatever country you come from. A local eSIM keeps data at a predictable and typically low price, which matters because the visa, the arrival declaration, the Bali levy, ride-hailing and maps all run through your phone.
