The Cheapest SIM Card for Tourists in Indonesia: Finding the Best Deal

You land in Indonesia tired and sticky, the humid air hits you at the arrivals door, and you need a Gojek or Grab right now. Then you see five SIM counters with five different price boards. Pick the wrong one and you either overpay or lose signal on the island you came to see. This guide breaks down the cheapest options for 2026, shows what you will likely pay in IDR, and explains the rules that catch tourists off guard. Prices below are approximate and based on late 2024 trends projected into early 2026, so always confirm the final price at the counter.

Why Your Passport Decides Everything

Every SIM card in Indonesia must be registered to an individual. This is a mandatory government rule. For tourists, registration means showing your passport at the point of purchase, and the SIM is then linked to your passport number.

The vendor enters your passport number, name, and date of birth into the system. They also register your phone’s IMEI number with the network operator, which links the SIM and your device for network access. The whole thing usually takes about five minutes.

Bring two things: your passport and an unlocked phone. A phone locked to your home carrier will not accept a local SIM, and no counter can fix that for you.

Cheapest to Most Expensive: Provider-by-Provider Breakdown

Here are the four main operators, ordered roughly from lowest price to highest. All plans below are 30-day plans.

Smartfren: The Lowest Prices

Smartfren is known for significantly lower data prices. Its tourist plans are the cheapest on the market, but its coverage is the most limited.

• Smartfren Tourist Pack: 15 GB, approximately IDR 40,000 – 70,000.
• Smartfren Super Kuota: 30 GB, approximately IDR 60,000 – 100,000.

You can buy at Smartfren Gallery stores, authorised resellers, and some convenience stores. Website: www.smartfren.com.

The catch is coverage. It is strong in urban centres and tourist hubs but patchy in very remote areas. Smartfren relies heavily on 4G/5G, so older phones may have compatibility issues. Check that your phone supports 4G before buying.

Indosat Ooredoo Hutchison (IM3): Balanced Value

IM3 is the main consumer brand of Indosat Ooredoo Hutchison, formed when Indosat Ooredoo merged with Three (Tri) Indonesia in 2022. It offers competitive pricing and good coverage, especially in Java and Bali.

• IM3 Tourist Starter Pack: around 20 GB, approximately IDR 70,000 – 120,000.
• IM3 Tourist Jumbo Pack: around 40 GB, approximately IDR 100,000 – 160,000.

Plans often include unlimited calls to other IM3 numbers and some minutes for other operators. You can buy at official IM3 stores, authorised resellers, and airport kiosks. Websites: www.im3.id and www.indosatooredoohutchison.com. Coverage can be less consistent than Telkomsel in very remote regions.

XL Axiata: Tourist-Specific Plans

XL Axiata offers good network performance in urban and tourist areas, plus a dedicated tourist product, the XL PRIORITAS Tourist SIM.

• XL PRIORITAS Tourist Silver: around 15 GB, approximately IDR 80,000 – 130,000.
• XL PRIORITAS Tourist Gold: around 30 GB, approximately IDR 120,000 – 180,000.

These often include international calls to selected countries as well as local calls and SMS. Buy at XL Center stores, authorised dealers, or airport kiosks. Website: www.xl.co.id. Like IM3, XL can be spotty in very rural or remote locations compared with Telkomsel.

by.U: Flexible but Needs Planning

by.U is Telkomsel’s fully digital brand. You build your own plan in the app and get Telkomsel’s network behind it. The base SIM costs around IDR 10,000 – 20,000, and data packages look like this:

• 10 GB for 30 days: approximately IDR 40,000 – 50,000.
• 25 GB for 30 days: approximately IDR 70,000 – 90,000.
• 50 GB for 30 days: approximately IDR 100,000 – 130,000.

You order through the by.U app (Google Play or Apple App Store), then either wait for delivery or collect at a designated point such as a convenience store or by.U booth. After that, you activate in the app by scanning your passport. This is not ideal for a quick start at the airport unless you order ahead. Whether tourists can get a by.U eSIM without extra steps is unclear, so check inside the app before you fly. Website: www.byu.id.

Telkomsel: Most Expensive, Most Reliable

Telkomsel is the largest operator in Indonesia, with the widest and most reliable coverage, especially in remote areas. It is generally not the cheapest.

• Tourist Starter Pack 1: around 25 GB, approximately IDR 100,000 – 150,000.
• Tourist Starter Pack 2: around 50 GB, approximately IDR 150,000 – 200,000.

Both include local calls and SMS. Data may be split into a national quota and specific app quotas, such as social media. Buy at official outlets (GraPARI), airport kiosks at Ngurah Rai (DPS) and Soekarno-Hatta (CGK), and some authorised resellers. Website: www.telkomsel.com.

2026 Budget Reality

For a typical 30-day stay with moderate to heavy data use (20 – 50 GB), here is what to expect in early 2026:

• Budget: Smartfren, approximately IDR 40,000 – 100,000. Best for city-focused trips with little remote exploration.
• Mid-range: IM3 or XL Axiata, approximately IDR 70,000 – 180,000. Strong for Java, Bali, and major cities elsewhere.



• Comfortable: Telkomsel or by.U, approximately IDR 100,000 – 200,000. The right choice if you will travel widely or need reliable service everywhere.

The gap between the cheapest and priciest tier is about IDR 100,000. That is less than one dinner in a tourist area, so do not save money on the SIM if losing signal could strand you on a remote island.

eSIM Instead of Plastic: Step-by-Step Activation

An eSIM removes the need to swap physical cards. You can start data the moment you leave the counter, and your home SIM stays in the phone for bank codes and messages. Indonesia is adopting eSIM gradually, and tourist access depends on the provider:

• Smartfren: has offered eSIM for several years and is generally the most accessible for tourists.
• XL Axiata: offers eSIM for prepaid and postpaid, including XL PRIORITAS plans.
• IM3: now offers eSIM for prepaid users, and tourists should be able to activate it.
• Telkomsel: offers eSIM for prepaid, including some tourist packages. Confirm availability through official channels.
• by.U: offers eSIM, but tourist activation may need a more complex setup. Verify before relying on it.

The general process:

1. Make sure your phone is eSIM compatible and unlocked.
2. Visit an official store: Smartfren Gallery, XL Center, IM3 Store, or Telkomsel GraPARI.
3. Tell staff you need an eSIM for a tourist plan.
4. Show your passport for registration.
5. Staff will give you a QR code.
6. On your phone, go to Settings > Cellular/Mobile Data > Add Data Plan/Add eSIM.
7. Scan the QR code.
8. Follow the on-screen prompts to activate.

Expect 5 – 10 minutes once you reach the counter. Do the eSIM setup in the store, not later at your hotel, so staff can fix problems on the spot.

Where to Buy: Airports, Official Stores, and Convenience Stores

Your purchase location affects price, speed, and the chance of a failed activation.

• Airports (CGK, DPS): the most convenient. Prices may be slightly higher, but activation is quick and staff are used to tourists. After a long flight, with the smell of clove cigarettes and jet fuel in the terminal air, a counter that handles everything in five minutes is worth a small markup.



• Official stores (GraPARI, XL Center, IM3 Store, Smartfren Gallery): best for guaranteed activation, staff help, and the full range of plans. Bring your passport.
• Indomaret and Alfamart: some basic prepaid SIMs are sold, but registration is usually self-service via SMS or an app. That is tricky without a local number. Official stores are the better choice.

Coverage Check: When a Cheap SIM Stops Being Cheap

A low price means nothing without a signal. Here is how coverage breaks down by region.

• Java and Bali: excellent across Telkomsel, Indosat Ooredoo Hutchison, and XL Axiata. Telkomsel has the edge in more rural parts. Smartfren is strong in urban centres but can be patchy in very remote areas.
• Sumatra, Sulawesi, Kalimantan: good in major cities and along main transport routes, then variable. Telkomsel usually holds the best coverage in remote parts.
• Remote islands (Nusa Tenggara, Maluku, Papua): often limited and challenging. Telkomsel is almost always the only viable option, and even then service may be restricted to specific towns or coastal areas. Smartfren coverage is usually non-existent.

The practical rule: sticking to Bali, Yogyakarta, Jakarta, and Bandung? Smartfren, IM3, or XL will do the job. Heading to Nusa Tenggara, Maluku, or Papua? Buy Telkomsel.

The 90-Day IMEI Rule: What Tourists Need to Know

This is separate from SIM registration. The rule applies to phones, handheld computers, and tablets brought in from overseas. If you plan to use a device with a local Indonesian SIM for more than 90 days, or with a foreign SIM for more than 90 days, its IMEI must be officially registered with the Ministry of Industry (Kementerian Perindustrian) and customs (Bea Cukai).

Under 90 days: your phone works normally with a local SIM. The operator registers your IMEI in its own system during activation. You do not pay import tax on your phone.

Over 90 days: you need to declare the phone at customs on arrival and may pay import duty if its value exceeds the exemption threshold, typically USD 500 per person. Then register the IMEI through the Bea Cukai website (www.beacukai.go.id) or app. There are no known exemptions for tourists who stay longer and want to keep using a local SIM. This rarely applies to ordinary holidays, but it matters if you are extending a trip.

Wi-Fi vs Mobile Data: Why Wi-Fi Alone Fails

Wi-Fi is widely available, but it does not replace a SIM.

• Accommodation: most hotels, guesthouses, and villas offer free Wi-Fi, with quality from basic to excellent.
• Cafes and restaurants: standard in tourist areas such as Bali, Jakarta, Yogyakarta, and Bandung.
• Airports: CGK and DPS offer free Wi-Fi, but it may need a local phone number or have time limits.
• Transport: generally not available on local buses or in Gojek and Grab cars. KAI trains often offer paid Wi-Fi, but mobile data is more reliable.

Gojek and Grab need constant internet for live location and driver chat. The KAI Access app benefits from a steady connection for ticket management and updates. Picture standing on a Yogyakarta roadside at dusk with the smell of grilled corn drifting from a nearby cart, watching your Gojek driver’s pin disappear because your phone has no data. A local SIM prevents that.

Topping Up Without a Local Bank Account

Each operator has its own app for checking balance and buying data: MyTelkomsel, myIM3, myXL, and MySmartfren. You can also buy credit (“pulsa”) or data packages at Indomaret or Alfamart with cash. Tokopedia, Shopee, OVO, and GoPay also allow top-ups, but they usually require local payment methods or accounts. For most tourists, the convenience store counter is the easiest route.

What Has Changed Since 2024

• More eSIM options: all major providers are making eSIM more common and accessible, including for tourists.
• Digital identity push: the government continues to promote digital verification, which may streamline registration further. Passport checks remain mandatory for foreigners.
• Indosat Ooredoo Hutchison integration: the Indosat and Tri merger has led to network consolidation and better coverage in some areas, and the integration should be fully mature by 2026. That could mean stronger competition for Telkomsel.
• Tourist plans: dedicated plans should continue. Data allowances may rise slightly, or prices may shift with inflation, but the structure should stay similar.
• No major discontinuations: no major tourist SIM products are known to have been discontinued, although specific data packages change often.

Common Mistakes to Avoid

• Buying the cheapest SIM for a remote island trip. Smartfren is great value in cities and useless where it has no coverage.
• Arriving with a locked phone. Check with your home carrier before you fly.
• Forgetting your passport. Registration requires it, and the vendor cannot activate the SIM without it.



• Relying on a convenience store SIM. Self-registration via SMS or an app is hard without a local number.
• Ignoring the quota split. A big headline GB number may include app-only quota.
• Planning to order by.U on arrival. It needs ordering and delivery or pickup, so order before you travel if you want it.
• Confusing SIM registration with IMEI registration. Under 90 days, the vendor handles the first and you can ignore the second.
• Assuming Wi-Fi is enough. It will not help you on the road.

Frequently Asked Questions

What is the cheapest SIM card for tourists in Indonesia?

Smartfren is usually the cheapest. Its 15 GB tourist pack costs around IDR 40,000 – 70,000, and the 30 GB Super Kuota around IDR 60,000 – 100,000. Coverage is limited outside major cities and tourist hubs, so it suits urban trips better than travel to remote islands.

Do I need my passport to buy a SIM card in Indonesia?

Yes. All SIM cards must be registered to an individual, and tourists register with a passport. The vendor enters your passport number, name, and date of birth, and registers your phone’s IMEI. Expect the process to take about five minutes at the counter.

Can I use an eSIM in Indonesia as a tourist?

In most cases, yes. Smartfren is generally the most accessible, and XL Axiata and IM3 also offer eSIM. Telkomsel offers it for some prepaid packages, so confirm tourist availability first. Your phone must be eSIM compatible and unlocked, and you register with your passport.

Do I have to pay tax or register my phone’s IMEI as a tourist?

Not if you stay under 90 days with a local SIM. The operator registers your IMEI during activation, and you pay no import tax. Beyond 90 days, you must register through Bea Cukai (www.beacukai.go.id), and duty may apply above the typical USD 500 exemption.

Which SIM works best on remote Indonesian islands?

Telkomsel. In Nusa Tenggara, Maluku, and Papua it is almost always the only viable option, though service may be limited to specific towns or coastal areas. Smartfren coverage is usually non-existent there. If your route leaves the main tourist trail, paying more for Telkomsel is worth it.
