Indonesia SIM Card Price Guide: What to Pay for Data & Calls

Most tourists in Indonesia worry about the price of a SIM card. In 2026 the bigger risk is a SIM that works perfectly at the airport counter and then goes dead a few days later. The cause is usually an unregistered phone, not a bad SIM. This guide covers what you should pay for data and calls, which operator suits your route, and how to avoid that silent cut-off.

Register Your IMEI Before You Buy a SIM

Indonesia requires every phone connecting to its mobile networks to have its IMEI (the unique device number) registered. The rule exists to stop illegal phone imports. Tourists are covered by a temporary exemption of up to 90 days of network access without paying customs duties. That exemption applies only if you use a local Indonesian SIM card.

If you stay longer than 90 days, or use an international roaming SIM beyond 90 days, you would theoretically need to pay customs duties on your device. For a normal holiday this will not affect you.

Here is the process for stays under 90 days:

1. Declare your phone. Declare your mobile phone(s) to customs officials when you arrive at an international airport.
2. Fill in the e-CD. This is the electronic customs declaration form, and it has a section for your device’s IMEI. You can often complete it online before arrival or at kiosks in the airport.
3. Submit your documents. Show your passport, boarding pass, and the e-CD with your IMEI to a customs officer.
4. Get registered. The officer registers your IMEI and links it to your passport details.
5. Keep your confirmation. You will usually receive a QR code or a digital receipt.
6. Buy and activate your SIM. Your phone’s IMEI is now recognised for temporary use, so the provider can activate your service.

To find your IMEI, dial *#06# on your phone. Airport customs desks are the most reliable place to register. Some official carrier stores may help, but do not count on it.

If you skip this step, your local SIM will likely stop connecting after a few days, often within 1 to 3 days. You will get an SMS warning, but by then you may be on a ferry or a mountain road with no way to fix it.

What You’ll Pay in 2026: Budget, Mid-Range, Comfortable

All prices below are estimates for 2026 in Indonesian Rupiah (IDR). Operators change package names and prices often, so confirm the exact figure at the counter or in the app before you pay. All plans below run for 30 days.

Budget: about IDR 70,000 to IDR 100,000

• Smartfren Tourist Data 30GB: 30GB, often with bonus data, for roughly IDR 70,000 to IDR 100,000.
• Telkomsel by.U: 30GB for roughly IDR 80,000 to IDR 100,000.

Mid-range: about IDR 80,000 to IDR 120,000

• XL Data Traveler 15GB: 15GB, unlimited local calls to XL, and 20 minutes to other operators, for roughly IDR 80,000 to IDR 110,000.
• IM3 Tourist Plan 20GB: 20GB, unlimited calls to IM3, and 30 minutes to other operators, for roughly IDR 90,000 to IDR 120,000.

Comfortable: about IDR 120,000 to IDR 150,000

• Telkomsel Tourist Combo 30 Days: 25GB, 50 local minutes and 25 local SMS for roughly IDR 120,000 to IDR 150,000.

The price gap is small. Even the most expensive option costs about the same as a few restaurant meals. So choose by coverage and route, not by saving a few thousand rupiah.

Telkomsel: Paying More for Reach

Telkomsel has the widest and most reliable coverage in Indonesia, including many remote areas. It also gives you excellent 4G/5G on Java, Bali and the major cities. It has two brands that suit different travellers.

• Telkomsel main brand: The premium service. The Tourist SIM Card is sold at airports and official outlets and bundles data, local calls and sometimes international calls. Manage it in the MyTelkomsel app. Website: www.telkomsel.com.
• by.U: A fully digital prepaid brand run entirely through an app. You download the app, choose a package, then pick up a SIM or activate an eSIM. Website: www.byu.id.

Choose the main brand if your route includes islands beyond Java and Bali, national parks, or mountain regions. In those places Telkomsel gives you the best chance of staying connected. Choose by.U if you stay in cities and tourist hubs and like to sort everything on your phone before you land.

IM3, XL and Smartfren: Value Plans for Cities and Tourist Hubs

These three operators compete hard on price for data in populated areas.

Indosat Ooredoo Hutchison (IM3)

IM3 has strong 4G/5G coverage in Java, Bali and major cities on other islands, and it is expanding quickly. Indosat is expected to have widespread eSIM availability in 2026, purchasable online or through the myIM3 app. Websites: www.indosatooredoo.com and www.im3.id.

XL Axiata

XL has excellent 4G/5G coverage in Java, Bali and major cities, and good coverage in many other populated areas. XL is anticipated to have widely available eSIM options in 2026, activated by QR code after an online purchase or through the myXL app. Website: www.xl.co.id.

Smartfren

Smartfren runs only on 4G LTE and 5G, which helps it offer very competitive data deals. Its coverage is excellent in major urban centres and tourist hubs but less extensive in rural or remote areas than Telkomsel. It was an early eSIM adopter in Indonesia, and its eSIM is easy to activate through the MySmartfren app or the website. Website: www.smartfren.com.

eSIM or Physical SIM: Choosing Your Format

The right format depends on your phone and how much hand-holding you want.

• Choose eSIM if your phone supports it. You can buy and install before you fly, so you skip the airport queue. Smartfren and Telkomsel (including by.U) are the easiest places to start.
• Choose a physical SIM if you want a person to help. At an official store, staff scan your passport, activate the package, and can often check whether your IMEI has been registered.

Global eSIM brands such as Airalo and Holafly also sell Indonesia plans. They may not work with the local IMEI registration and might use roaming partners. A local provider’s eSIM is the safer choice for a long stay, because the IMEI requirement applies to the phone itself, whichever SIM you use.

Step-by-Step: Activating a Physical SIM

1. Buy from the right place. Official stores are Telkomsel GraPARI, IM3 Store, XL Center and Smartfren Gallery. Airport kiosks and convenience stores such as Indomaret and Alfamart also sell SIMs. Official stores are best because staff can help with registration.
2. Hand over your original passport. Staff scan it and enter your details into the system.
3. Ask for an IMEI check. If your IMEI is not registered, they may tell you what to do next.
4. Insert the SIM. Staff will often do this for you.
5. Activate your package. The staff usually do it for you. If not, dial a USSD code such as *123# or use the provider’s app.
6. Look for the confirmation SMS. It should show your new number and your activated package.

Step-by-Step: Installing an eSIM

1. Check compatibility. Make sure your smartphone supports eSIM.
2. Buy a local plan. Use the provider’s website or app, for example Telkomsel or Smartfren.
3. Handle your IMEI. Register your phone with Indonesian customs on arrival so the eSIM keeps working with a local plan.
4. Collect the QR code. It arrives by email or in the app.
5. Add the plan. Open your phone settings, usually under “Cellular” or “Network & Internet”. Choose “Add Cellular Plan” or “Add eSIM” and scan the QR code.
6. Follow the prompts. The plan should activate shortly after installation.

Coverage Reality Across the Islands

Your SIM choice matters most when you leave the main tourist circuit.

• Excellent: Java and Bali, with strong 4G and growing 5G in urban and tourist areas.
• Good: Major cities on Sumatra, Sulawesi and Kalimantan, typically with good 4G/5G.
• Variable to poor: Very remote areas, smaller islands, mountain regions and national parks. Signal can be weak or missing. Telkomsel offers the best chance of connectivity here.

In 2026, 5G is expected to expand significantly in major metropolitan areas and possibly some key tourist zones. You only benefit if your phone is 5G-compatible.

How Far Free WiFi Actually Takes You

WiFi is widely available and usually free in cafes, restaurants, hotels, guesthouses and homestays in popular destinations and urban areas.

Public WiFi in open spaces is less common and often unreliable. You cannot build a trip around it. You need mobile data for Google Maps, ride-hailing on Gojek and Grab, train tickets on KAI Access, and keeping in touch while you move between places.

What Has Changed Since 2024

• IMEI rules: The registration requirement and the 90-day tourist exemption for local SIM use have been stable since full implementation. No major changes are expected for 2026, but check the latest customs rules before you fly.
• eSIM: Expect wider and smoother activation across Telkomsel, Indosat, XL and Smartfren.
• Tourist packages: Providers are likely to offer more refined and competitive Tourist SIM or Traveler packages with clearer benefits.



• Options: No major provider is expected to be discontinued. The market is more likely to see consolidation and refinement, and by.U remains a strong digital-first option.

Common Mistakes That Cost Tourists Money

• Skipping IMEI registration. This is the biggest one. Your SIM may stop connecting after 1 to 3 days, and you will have paid for data you cannot use.
• Relying on a roaming SIM past 90 days. Both roaming and local SIM use beyond 90 days could theoretically trigger customs duties on your device.
• Buying a random SIM from a non-official seller. You lose the staff help with passport registration and IMEI checks.
• Forgetting your passport. Registration needs your original passport, not a photo.
• Assuming a global eSIM equals a local one. Global brands may not tie in with local registration and might route through roaming partners.
• Picking the cheapest plan for a remote trip. Smartfren is great in cities but less extensive in rural areas. For national parks and small islands, Telkomsel is safer.
• Not downloading the app. MyTelkomsel, by.U, myIM3, myXL or MySmartfren lets you check data and top up. Also install Gojek, Grab and KAI Access before you go.

Frequently Asked Questions

How much does a tourist SIM card cost in Indonesia in 2026?

Expect roughly IDR 70,000 to IDR 150,000 for a 30-day package. Smartfren and by.U sit at the lower end, while the Telkomsel Tourist SIM is at the top. These are estimated figures, so confirm the exact price and package name at the counter or in the app.

Do I need to register my phone’s IMEI as a tourist?

Yes. Every phone on Indonesian networks needs a registered IMEI. Tourists get a temporary exemption of up to 90 days with a local SIM, without customs duties. Declare your phone at airport customs. Without registration, your SIM will likely stop working after 1 to 3 days.

Which operator has the best coverage in Indonesia?

Telkomsel has the widest and most reliable coverage, including many remote areas. Indosat IM3, XL and Smartfren are excellent on Java, Bali and major cities. Smartfren is less extensive in rural and remote areas, so choose Telkomsel if you are heading off the main tourist routes.

Is an eSIM or a physical SIM better for Indonesia?

If your phone supports eSIM, it saves queue time because you can install it by QR code. Smartfren is an early adopter. A physical SIM from an official store gives you staff help with passport registration and IMEI checks. Either way, your phone’s IMEI must be registered.

Can I rely on WiFi instead of a SIM card?

Not safely. WiFi is usually free in cafes, restaurants, hotels, guesthouses and homestays in tourist areas, but public WiFi is less common and often unreliable. You need mobile data for Google Maps, Gojek, Grab and KAI Access, especially when moving between locations.
