You clear immigration at Soekarno-Hatta or Ngurah Rai, you need to book a Gojek, and your hotel confirmation is sitting in an email you can’t load. That is the exact moment tourists realize they should have sorted a local SIM before walking out of arrivals. In 2026, the process of getting Connected in Indonesia is faster and more digital than it was two years ago — but there are still a few rules, registration steps, and package choices that can trip you up if you don’t know what to expect. This guide focuses on the Indosat Ooredoo (IM3) Tourist SIM, covers how it stacks up against competitors, and walks through everything you need to stay connected from the moment you land.
What Is the IM3 Tourist SIM and What Do You Actually Get?
Indosat Ooredoo operates under the brand IM3 and is one of Indonesia’s four major telecommunications providers. It holds a strong position in urban centres and popular tourist corridors — Bali, Java, Lombok, and most of Sumatra — making it a practical choice for the majority of visitors who stick to well-travelled routes.
IM3 sells prepaid packages specifically aimed at tourists, often labelled as “IM3 Tourist SIM” at airport kiosks. As of 2026, the standard package tiers look like this:
- 10 GB / 30 days: approximately IDR 50,000 – IDR 75,000
- 25 GB / 30 days: approximately IDR 100,000 – IDR 125,000
- 50 GB / 30 days: approximately IDR 150,000 – IDR 200,000
These prices generally include the physical SIM card itself. Each tier includes either unlimited or a generous allowance of local calls and SMS within Indonesia — enough for booking confirmations and the occasional call to a hotel. The 25 GB package is the sweet spot for most travellers: it covers two to three weeks of heavy Google Maps use, constant WhatsApp, daily Instagram uploads, and a few hours of streaming without hitting the wall.
The SIM runs on 4G/LTE across most of Java and Bali, and the IM3 network has seen gradual 5G expansion into major urban centres like Jakarta, Surabaya, and Denpasar through 2025 and into 2026. For most tourists, though, 4G speeds are more than adequate — you’ll get fast, responsive data in any busy tourist area.
Account management is handled through the MyIM3 app, available on both Google Play and the Apple App Store. Through the app, you can check your remaining data balance, buy top-up packages, and reach customer support. The official website is im3.id.
How to Buy and Activate Your IM3 SIM Step by Step
The activation process at an official counter takes between 5 and 15 minutes. Here is exactly what happens:
- Find an official IM3 counter. The most convenient option is the IM3 kiosk inside arrivals at Jakarta (CGK), Bali (DPS), or Surabaya (SUB). Official Gerai Indosat Ooredoo stores exist in virtually every city. Convenience stores like Indomaret and Alfamart sell IM3 SIM cards, but staff there cannot complete the full passport-based registration — stick to official points.
- Hand over your passport. The staff member will scan your passport and enter your name, date of birth, nationality, and passport number into the IM3 registration system. You need your actual passport — a photo on your phone is not sufficient.
- Provide your IMEI number. Dial *#06# on your phone to display your IMEI. The vendor registers this number alongside your passport details. This step is mandatory under Indonesian regulations (covered in detail in the next section).
- SIM insertion and activation. The vendor inserts the SIM, selects your chosen package, and confirms the connection. Before you leave the counter, open a browser or check Google Maps to confirm data is live.
- Download MyIM3. Set up the app while you’re still at the counter so you can monitor your balance from day one.
You can also top up your package at any time through the MyIM3 app, at official Indosat stores, or by purchasing top-up vouchers at Indomaret and Alfamart. Top-up codes are printed on small physical vouchers at the counter or delivered digitally through the app.
The IMEI Registration Requirement: What Tourists Must Know
This is the rule that catches the most tourists off guard. Since April 2020, Indonesia has required all foreign-purchased mobile phones using a local SIM card to have their IMEI registered with the government. The regulation exists to combat the black market for phones and ensure import taxes are properly collected. In 2026, enforcement is more consistent and the system is more integrated than it was at launch.
Here is what the rule actually means for you:
- Phones valued under USD 500 (roughly IDR 7.5 million, subject to exchange rate fluctuation) are exempt from import tax — but their IMEI still needs to be registered.
- Phones valued over USD 500 are subject to approximately 17.5% tax on the amount exceeding USD 500 (10% VAT plus 7.5% income tax). So a USD 700 phone would incur tax on USD 200.
- Grace period: An unregistered foreign phone will continue working with a local SIM for approximately 90 days. For most tourists this means the SIM will function throughout their visit even without pre-registration — but getting it done properly at the airport counter eliminates any uncertainty.
- eSIM users are not exempt. Even if you activate a digital eSIM rather than inserting a physical card, your device’s IMEI must still be registered.
There are two ways to complete IMEI registration:
- Online via Bea Cukai (Indonesian Customs): Visit beacukai.go.id/register-imei.html or use the Mobile Bea Cukai app. Fill in your personal details, flight information, and IMEI number(s). You receive a QR code to show at the customs counter on arrival. This can be done before you board or during your flight.
- At the SIM card counter: When you purchase your IM3 SIM at an official airport kiosk, the staff handle IMEI registration as part of the activation process. For most tourists, this is the easiest route — you hand over your passport and IMEI, and it is done as part of getting your SIM.
Since 2024, the Bea Cukai online system has been improved significantly for ease of use, and SIM card vendors at airports are now more consistently integrated with the registration system. The handoff is smoother, and errors at the point of sale are less common than they were in 2022 and 2023.
IM3 vs. Telkomsel vs. XL Axiata vs. Smartfren: Which Fits Your Trip?
Choosing the right provider depends on where you are going, not just the price per gigabyte.
Telkomsel
Telkomsel is Indonesia’s market leader and has the widest, most reliable coverage across the archipelago — including remote areas where other networks drop out entirely. Their tourist prepaid packages range from IDR 100,000 to IDR 300,000 for 25 GB to 100 GB over 30 days. They are slightly more expensive per GB than IM3, but if your itinerary includes Raja Ampat, rural Sulawesi, or anywhere in Eastern Indonesia, Telkomsel is the only sensible choice. Account management runs through the MyTelkomsel app. Website: telkomsel.com.
Telkomsel by.U
by.U is Telkomsel’s fully digital sub-brand and runs entirely through an app. It was one of the first Indonesian networks to offer eSIM, and in 2026 it remains one of the most straightforward eSIM options for tourists. Everything — purchase, registration, package selection — happens inside the by.U app. Website: byu.id.
XL Axiata
XL Axiata offers competitive packages in the IDR 75,000 to IDR 175,000 range for 15 GB to 40 GB over 30 days. Coverage on Java and Bali is strong, and it is a solid alternative to IM3 if you find a better deal at the counter. The myXL app handles account management. Website: xl.co.id. Coverage deteriorates faster than Telkomsel outside major population centres.
Smartfren
Smartfren is the value-for-money option and the easiest provider for eSIM activation. The MySmartfren app lets you complete passport scan, selfie verification, IMEI entry, and QR code activation entirely on your phone — no physical store needed. The trade-off is coverage: Smartfren runs on 4G LTE-Advanced only, and outside cities and large towns, the signal can disappear entirely. Fine for a Bali beach holiday; not ideal if you’re heading off the beaten track. Website: smartfren.com.
Quick Comparison Summary
- Best coverage (remote areas): Telkomsel
- Best value for city-based travel: IM3 or Smartfren
- Easiest eSIM setup: Smartfren or by.U
- Best balance of price and coverage: IM3
eSIM Options in Indonesia for 2026
eSIMs have become meaningfully easier to activate in Indonesia since 2024. The appeal is obvious: you keep your home SIM active for calls while running Indonesian data on the same device, and you skip the queue at the airport SIM counter.
The process for any Indonesian eSIM follows the same basic structure:
- Confirm your phone supports eSIM — iPhone XS/XR and later, Google Pixel 3 and later, and newer Samsung Galaxy models all qualify.
- Download the provider’s app (MySmartfren, by.U, or the relevant provider app).
- Select a package, then complete digital registration: upload your passport photo page, take a selfie for identity verification, and enter your IMEI.
- Once approved — typically 15 minutes to a few hours depending on verification load — you receive a QR code inside the app or by email. Scan it to activate the eSIM profile on your device.
In 2026, Smartfren and by.U remain the clearest paths for tourist eSIM activation without needing to visit a physical store. Indosat Ooredoo and XL Axiata have been expanding their eSIM offerings, and by 2026 both are expected to offer more streamlined digital activation — but the process may still be less polished than Smartfren or by.U for a first-time tourist completing everything remotely.
One practical note: eSIM activation requires a working internet connection to complete the setup. If you are doing this on arrival at the airport, use the airport WiFi. If you are doing it before you travel, complete it while still at home on your regular data connection.
Coverage Reality: Where IM3 Works and Where It Doesn’t
IM3 covers the places most tourists actually visit without any issues. Walk through Seminyak or Canggu at dusk — the air smells of frangipani and exhaust, motorbikes thread between pedestrians, and your IM3 data streams Google Maps without a hiccup. The same is true across Yogyakarta’s city centre, along the Prambanan highway, in Ubud, and through the café-lined streets of Jakarta’s Kemang district.
Here is the honest coverage breakdown:
- Excellent (4G/LTE, reliable): All of Java, Bali, Lombok, major cities in Sumatra (Medan, Padang, Palembang, Lampung), Makassar in Sulawesi, and the main tourist corridors between these places.
- Good (4G in towns, 3G on roads): Larger towns in Sumatra, parts of Kalimantan, Manado and surrounding areas in North Sulawesi, larger islands in Nusa Tenggara.
- Variable or limited (3G, 2G, or no signal): Remote islands, mountainous interior regions, and most of Eastern Indonesia outside main towns. This includes popular but isolated spots like the Gili Islands (decent but not always reliable), parts of Flores, and the more remote reaches of West Papua.
The single most important rule: if your trip takes you beyond Java, Bali, or main Sumatra routes, seriously consider Telkomsel instead of IM3. The coverage gap in remote areas is real, and there is nothing worse than standing at a trailhead in East Nusa Tenggara with no signal and no downloaded offline maps.
2026 Budget Reality: What You’ll Actually Pay
Indonesian SIM card pricing is genuinely cheap by global standards. Here is what to expect in 2026 across all tiers:
Budget
- 10 GB / 30 days: IDR 50,000 – IDR 75,000 (IM3 or XL Axiata)
- Suits short trips of one to two weeks with moderate usage — maps, messaging, occasional social media.
Mid-Range
- 25 GB / 30 days: IDR 100,000 – IDR 125,000 (IM3), up to IDR 175,000 (XL Axiata)
- The standard choice for most tourists on a two-to-four-week trip. Handles maps, streaming, video calls, and daily uploads comfortably.
Comfortable
- 50 GB / 30 days: IDR 150,000 – IDR 200,000 (IM3), up to IDR 300,000 (Telkomsel)
- For heavy users, remote workers, or anyone planning to tether a laptop or tablet to their phone’s hotspot.
eSIM packages are priced comparably to physical SIM packages across all providers. The SIM card itself costs IDR 5,000 – IDR 10,000 or is included in the package price.
If your phone value exceeds USD 500, factor in the IMEI tax: approximately 17.5% on the value above USD 500. A USD 700 phone incurs tax on USD 200 — roughly IDR 3,000,000 at current rates, meaning a tax of approximately IDR 525,000. This is a one-time cost paid at customs, not a recurring charge.
Top-up options are widely available. You can add data through the MyIM3 app, at any Indosat Ooredoo store, or at Indomaret and Alfamart convenience stores, which are genuinely everywhere in Indonesia — even in smaller towns.
Common Mistakes Tourists Make With Indonesian SIM Cards
These are the errors that show up repeatedly, and all of them are avoidable.
Buying at a Convenience Store Without Checking Registration
Indomaret and Alfamart sell SIM cards, but staff are not set up to complete the full passport and IMEI registration. A SIM purchased here without proper registration will work initially thanks to the grace period — but you have no record of the registration and may hit problems if you stay longer or return to Indonesia. Always use an official airport counter or Gerai Indosat Ooredoo store for your first purchase.
Not Unlocking Your Phone Before Arriving
An Indonesian SIM inserted into a carrier-locked phone simply will not work. Check with your home carrier before you travel. Most modern phones can be unlocked for free after a certain period of service, but you may need to request it explicitly. Indonesian networks use GSM 900/1800 MHz, 3G 2100 MHz, and 4G LTE on bands B1, B3, B8, and B40 — confirm your handset is compatible.
Forgetting to Download Apps Before Arrival
You want Gojek, Grab, Google Maps (with offline maps downloaded), KAI Access for train tickets, and your provider’s app (MyIM3, MyTelkomsel, by.U, or MySmartfren) already on your phone before you land. Setting up Gojek for the first time requires SMS verification — which is much simpler once you have a working local SIM, but the app download itself is better done on fast home WiFi.
Assuming the Same Package Works Everywhere
Some IM3 tourist packages include data that is split between full-speed and throttled allowances, or between national and regional quotas. Read the package details at the counter, or check im3.id before you commit. Ask the staff member to confirm the package is a flat national data plan with no regional restrictions.
Not Checking IMEI Registration Status After Purchase
If there was any confusion at the counter — a busy queue, a new staff member, a system glitch — your IMEI registration may not have completed properly. Cross-check your status at beacukai.go.id/register-imei.html the same day you buy your SIM. It takes two minutes and saves potential headaches later in the trip.
Frequently Asked Questions
Can I buy an IM3 Tourist SIM at the airport before going through immigration?
No. IM3 kiosks are located in the arrivals hall, after you clear immigration and customs. This means you won’t have a local SIM until you have already passed through passport control. Download offline Google Maps for your destination city before you fly, and use airport WiFi to book a transfer if needed while you queue for your SIM.
Do I need to register my IMEI if I’m only in Indonesia for a week?
Yes, registration is still required, but the grace period of approximately 90 days means your SIM will function normally throughout a short trip even if the full registration wasn’t completed independently — as long as the airport vendor registered it at the point of sale, which they should. If you’re uncertain, verify your status at beacukai.go.id/register-imei.html.
Is the IM3 Tourist SIM good for Bali specifically?
Yes. Bali is one of IM3’s strongest coverage areas. You will get consistent 4G/LTE across Seminyak, Kuta, Ubud, Canggu, Nusa Dua, and Sanur. Coverage on the Bukit Peninsula and in the central highlands around Kintamani is generally solid, though speeds can dip in very rural northern Bali. For most Bali itineraries, IM3 performs without issue.
Can I use an eSIM in Indonesia instead of a physical IM3 SIM?
eSIM is available in Indonesia, but IM3’s tourist-specific eSIM activation is less streamlined than Smartfren or Telkomsel’s by.U. If you prefer eSIM, those two providers are currently the clearest options for tourists completing setup without a physical store visit. Your device’s IMEI still requires registration regardless of whether you use a physical SIM or eSIM.
What happens if I run out of data on my IM3 Tourist SIM?
You can top up at any time through the MyIM3 app using a linked debit or credit card, at any official Indosat Ooredoo store, or by purchasing a top-up voucher at Indomaret or Alfamart. Top-up vouchers are available in fixed denominations from around IDR 10,000 upward. Additional data packages can be activated through the app without replacing the SIM card or repeating the registration process.
