About this eSIM
Indonesia is more than 17,000 islands, and mobile coverage varies enormously: from dense networks around Denpasar and Jakarta to volcanoes, national parks and remote islands where signal is not guaranteed. Travelers need data all the time for ride-hailing, maps, translation and booking boats. An eSIM lets you get connected before you leave home, instead of hunting for an operator shop after a long flight.
Buy an eSIM or SIM card for Indonesia
You can buy an eSIM for Indonesia online right on this page from 3 500 ₸: choose a data plan, pay by card and get the QR code within minutes. An eSIM is a digital SIM card — it installs on your phone with no plastic card and no visit to a phone shop.
The eSIM connects to local mobile networks, so you have data wherever they have coverage — Jakarta and Bali and the rest of the country.
Roaming in Indonesia with a Kazakh carrier is usually far more expensive, and roaming data runs out fast. With a Funsim eSIM you pay a fixed price for a data package and keep your home SIM in the phone for calls and bank SMS — roaming on it can stay off.
If your phone does not support eSIM, you can buy a regular physical SIM card with data for Indonesia at a Funsim point of sale: at Almaty and Shymkent airports, or at our offices in Almaty — 130/1 Abay St and 1 Pozharsky St. Handy if you remember about the internet right before departure.
Why an eSIM in Indonesia beats roaming and a local SIM
Landing in Denpasar or Jakarta usually follows a long flight with a connection, and the first things to do are order a car and tell your host you have arrived. If the eSIM is already installed, you just switch on data for it after landing and can use maps and ride apps without queuing at the airport. You also pay for data in advance, so you know the package size before the trip and can track usage in your phone settings.
Indonesia is a country of routes: many travelers change islands, fly to Yogyakarta or Lombok, or sail to Labuan Bajo. One eSIM with nationwide coverage means no swapping SIM cards at every move. See the plans above for current options and data amounts. Roaming from Kazakh operators is usually much more expensive, so check your own operator's rates. A local SIM makes sense for long stays if you are ready to spend time buying and registering it, but for a holiday an eSIM is usually simpler.

Where an eSIM helps in Indonesia: cities, islands and routes
Coverage is uneven: the farther you are from big cities and tourist hubs, the more your signal depends on terrain and distance to towers.
Ngurah Rai Airport and south Bali
The main gateway to the island is Denpasar airport. Here, and in Kuta, Seminyak, Sanur and Nusa Dua, the network is dense and you need data immediately: to order transport, message the hotel, find a meeting point. Switching on your eSIM right after landing saves you the queue for a local SIM in the terminal. Traffic between the airport and the resort areas can be slow, so navigation and contact with your driver come in handy. Note that at rush hour the road from the airport to Ubud or Canggu can take much longer than the map suggests.
Ubud and central Bali
Ubud is surrounded by rice terraces, forests and small villages. In town the connection is solid, but on the way to waterfalls and temples deeper in the island quality changes. Online maps and messaging with guides and drivers are useful, and important addresses are best saved offline. This is also where you book workshops, yoga classes and tours through messengers. If you stay for several days, it is easy to plan routes by day and check opening hours on the map.
Kintamani, Munduk and northern Bali
Mountain roads wind past lakes, craters and plantations. Viewpoints usually have a signal, while valleys between the hills can drop it. Download the area map in advance and keep booking links and tickets stored on your phone.
Jakarta
The country's largest city, with millions of residents and constant traffic jams. Mobile networks are best developed here, and you need data for taxis, delivery, the metro and commuter trains. For business trips an eSIM is handy because it frees you from hotel or coworking Wi-Fi, and you can work from a taxi between districts if the route is clear. The city has plenty of malls and cafes with Wi-Fi, but your own mobile data is more reliable, especially when moving between districts.
Yogyakarta, Borobudur and Prambanan
The center of cultural tourism on Java. The city has stable coverage, and temple complexes usually get a signal, but tickets and visiting times are better checked in advance. Data helps for ordering transport to the temples and for e-tickets, and for contacting a guide who meets your group at dawn.
Bromo and Ijen in East Java
Volcano tours often begin at night, and on the craters and in mountain villages the signal can be patchy. Key tour details, such as departure time, meeting point and guide contact, are best agreed and saved before you head into the mountains.
Lombok and Kuta Lombok
Bali's neighbor island is popular with surfers and beach lovers. Resort areas are covered, while remote beaches and the approach to Rinjani have a weaker signal. You need data for transfers, boats to the Gili islands and vehicle rental, and on the coast you can work remotely if you stay in an area with a good network.
Labuan Bajo and Komodo
Boats to the Komodo dragons and the islands of Flores depart from here. The town has a network, but during sea trips the signal often drops. Save your agreements with the tour operator and booking details before setting out. Many tours last several days with nights on the boat, so phone battery and offline materials matter more than a constant connection.
Remote regions: Sulawesi, Papua, Raja Ampat
Connectivity here depends heavily on the specific island and the distance from settlements. If your route passes through such places, do not count on stable internet outside towns and download everything you need in advance. Domestic flights and boat schedules change here, so check current details with the carrier while you still have internet.
Apps that come in handy in Indonesia
Most of these services need internet, which is the main reason to have a data eSIM.
Grab
Ride-hailing and delivery
One of the main services for ordering taxis and food across Southeast Asia. It works in many Indonesian cities, and you see the price and route before the ride. Before your trip check that the app works with your number and payment method, and save your hotel address for the driver.
Gojek
Ride-hailing and delivery
A local super-app: car and motorbike rides, food delivery and other services. Popular in Indonesia with both locals and tourists.
Google Maps
Navigation
The main tool for routes in Bali and in cities. Before heading into the mountains or to remote islands, download an offline map of the area. Mark your accommodation, the airport and the beaches you want, so you can find them without a signal.
Traveloka
Booking
An Indonesian service for hotels, flights and train tickets. Useful for finding domestic flights between islands, and prices are shown in rupiah.
GoPay
Digital payments
A wallet tied to the Gojek ecosystem, common in the country. It is not required for tourists, but it is worth knowing that QR code payments are very widespread in Indonesia.
Google Translate
Translation
Helps you communicate with drivers, sellers and in small guesthouses. Camera translation is handy for menus and signs; for offline use, download the Indonesian language pack.
WhatsApp
Messenger
The main way to reach villa hosts, drivers, guides and instructors in Bali. It needs to be registered on your main number, while messages and calls run over the eSIM's data. It is handy for sending your host a location pin and voice messages if language is a barrier.
Bluebird
Taxi
A well-known Indonesian taxi service with its own app, especially in Jakarta and Bali. Useful when you want a metered car and clear payment.
Practical information for a trip to Indonesia
Currency
The Indonesian rupiah (IDR). Denominations are large, so price tags carry many zeros; double-check the amount before paying.
Sockets and voltage
Type C and F sockets, 230 V, 50 Hz. A standard European plug usually fits without an adapter.
Emergency services
The general emergency number is 112. Separate numbers exist for police, ambulance and fire; save the ones you need in advance, along with your hotel's and insurer's contacts so you can reach them by messenger if voice calls fail.
Time difference
Bali and Lombok are 3 hours ahead of Kazakhstan; Jakarta and Java are 2 hours ahead. Indonesia does not observe daylight saving time.
Language
The official language is Indonesian. In tourist areas of Bali many people speak English; in smaller towns a translator app helps.
Payments
Hotels, restaurants and shops accept cards, but small places and markets often need cash rupiah. QR payment is very common. ATMs inside malls or banks are handier for cash; check your bank's fees.
Water and tipping
Tap water is usually not drunk, so buy bottled water. Tipping is not mandatory, and restaurants often include a service charge.
Road traffic
Traffic drives on the left and scooters are the main transport. Check in advance which driving license and insurance you need to rent a scooter in your situation, and do not rely on the rental owner's verbal assurances.
Connectivity on site
Cafes, hotels and coworking spaces in Bali usually have Wi-Fi, but speed varies a lot. In the rainy season wired internet at villas can be unstable, and a mobile eSIM becomes the backup channel.
How to set up an eSIM for your Indonesia trip
1
Check that your phone supports eSIM and is not carrier-locked. At home, choose a suitable plan on this page and pay by card. Make sure your iOS or Android version is up to date, which lowers the risk of installation problems.
2
Install the eSIM at home on Wi-Fi: scan the QR code, tap the quick install button or enter the details manually.
3
Keep your main SIM in the phone for calls and bank SMS. Select the eSIM for mobile data in your settings. Turn off automatic switching of mobile data to the main line if it could trigger expensive roaming.
4
After landing in Denpasar, Jakarta or another airport, switch on data for the eSIM and, if needed, data roaming on that line.
5
If there is no internet, restart the phone and check that the eSIM line is selected. If your data runs out, you can buy an extra package.
Before flying to remote islands or heading into the mountains, download offline maps of the area and save accommodation addresses, bookings and guide contacts on your phone.
Questions before your trip
Can I buy an eSIM for Indonesia without a passport?
Yes, a passport is not needed to buy from Funsim, and you pay by card online. Local SIM cards are usually issued against a document, so an eSIM is simpler here. Do not forget to check current entry rules for citizens of Kazakhstan before the trip.
Do calls and SMS work on the eSIM?
Most plans include data only. Use messengers for calls and messages, and keep your main SIM in the phone for calls and bank SMS.
Do I need to turn on roaming for the eSIM?
Yes, after arrival switch on data for the eSIM and data roaming on that line. You can turn off mobile data on your main SIM so you do not pay for roaming.
Will one eSIM be enough for Bali, Java and Lombok?
Plans for Indonesia are designed for travel around the country; check the details and coverage on the chosen plan's page. You usually do not need to change profile between islands, but on boats, in the mountains and on remote islands the signal still depends on local coverage.
Can I use the eSIM to share internet?
Most plans support hotspot mode, but check the terms on the plan page before buying. That way you can work from a laptop in a cafe or a villa if the Wi-Fi is unstable.
What should I do if the internet disappears in the mountains or on a boat?
This is normal far from towers. Download offline maps and save bookings beforehand, and once you return to a coverage area the connection will recover.
What if my data runs out early?
You can buy an extra package for the same eSIM. Keep an eye on usage and turn off automatic app updates while traveling. Before heading to remote islands it is better to choose a package with a reserve at once, because topping up without a network is harder.
Is it worth buying an eSIM for Indonesia in advance rather than on arrival?
In advance is better: you install the profile at home on stable Wi-Fi and lose no time after the flight. In airports and tourist areas it is also easy to end up in a queue or overpay for a SIM, while buying online makes the terms clear beforehand.
Where can I buy an eSIM for Indonesia?
Online at funsim.kz: choose a plan for Indonesia, pay by card and install the eSIM with the QR code. No passport is needed, and you can install it at home before the trip.
Which is cheaper in Indonesia: roaming or an eSIM?
For mobile data an eSIM is usually much cheaper than roaming with a Kazakh carrier, because you buy a data package at a fixed price. Your home SIM stays in the phone for calls and SMS.
Where can I buy a SIM card for Indonesia in Almaty or Shymkent?
At Funsim points of sale: Almaty airport, Shymkent airport, and our Almaty offices at 130/1 Abay St and 1 Pozharsky St. If your phone supports eSIM, buying the digital SIM online is faster: it arrives right after payment.
Where does the eSIM work in Indonesia?
Yes. The eSIM uses local mobile networks, so data works wherever they have coverage — Jakarta and Bali and other cities and resorts of Indonesia.
