Indosat Ooredoo Tourist SIM: Coverage, Plans, and How to Get One

You land at Soekarno-Hatta after a long flight, the humid air hits you, and you need a Gojek or Grab right now. But the airport WiFi keeps dropping and your home roaming bill is already a worry. In 2026, a local SIM or eSIM is still the simplest fix. Indosat Ooredoo, sold under the IM3 prepaid brand, is one of the best-value options for visitors who stick mostly to Java and Bali. This guide explains the coverage, the plans, and exactly how to get one.

Why WiFi Alone Is Not Enough

Connectivity in Indonesia is more than checking Instagram. You need Google Maps and Waze to get around, WhatsApp to talk to hosts and drivers, Gojek and Grab for rides and food, and apps for booking trains with KAI and flights. A mobile data connection keeps all of this working while you move between places.

Picture a scooter ride through the rice-field lanes outside Ubud at sunset. You are following Google Maps, a driver is messaging you on WhatsApp, and the smell of satay smoke drifts from a roadside warung. None of that works on hotel WiFi. It also matters for safety, especially when you travel beyond the big cities.

The 90-Day IMEI Rule and What Changed Since 2024

Since 2020, Indonesia has used an IMEI (International Mobile Equipment Identity) registration policy to limit the grey market for phones. For tourists, the rules are simple:

• 90-day exemption: You can use your foreign-bought phone with a local SIM for 90 days from your arrival date without registering the IMEI.
• After 90 days: Local network access on the phone is blocked unless the IMEI is formally registered and any import taxes are paid.
• Tourist SIMs: SIM cards from official providers (Indosat Ooredoo, Telkomsel, XL Axiata, Smartfren) work within this window. The SIM is registered to your passport, not to your phone’s IMEI, for short stays.

The 90-day exemption has been kept since 2024. For most visitors staying under 90 days, buying a local SIM and registering it with your passport is enough. You no longer need to register your IMEI at the airport for short-term use. If you plan to stay close to 90 days or longer, check with your provider or an official store whether a simplified registration process exists for longer stays, because the rules for extended visits may be updated.

What IM3 Covers: Java, Bali, and Beyond

Indosat Ooredoo’s IM3 is a strong competitor to Telkomsel and XL Axiata, especially on Java and Bali.

Java and Bali

Expect excellent 4G/5G coverage in all major cities, tourist areas, and along main transport routes. That includes reliable service for KAI train journeys and for Gojek and Grab. If your trip is Jakarta, Yogyakarta, Bandung, Bali, or a similar route, IM3 will serve you well.

Other Islands

• Sumatra, Kalimantan, Sulawesi: Good 4G/5G in provincial capitals and larger towns. In remote rural areas, service can become variable or drop to 3G or 2G.
• Lombok: Generally reliable in tourist hubs like Senggigi and Kuta Mandalika.
• Flores: Generally reliable around Labuan Bajo.

Coverage figures for 2026 are projections based on current network trends, so treat the remote-area details as a guide, not a guarantee.

IM3 Tourist Plans and 2026 Budget Reality

Indosat Ooredoo typically offers tourist packages that combine data, local calls, and SMS, valid for 30 days. They are usually bundled with the physical SIM card purchase. The example package for 2026 is the IM3 Tourist Starter Pack:

• Price: IDR 75,000 to IDR 120,000, depending on data allowance
• Data: 25GB to 50GB of high-speed data (4G/5G)
• Calls and SMS: Unlimited to other IM3 numbers, plus 50 to 100 minutes to other local operators
• Validity: 30 days
• Extras: Often social media bonuses or reduced-rate international calls

Here is how that looks as a simple budget guide:

• Budget: The lower end of the IM3 range, around IDR 75,000 for about 25GB. This is enough for maps, messaging, ride-hailing, and light browsing over a month.
• Mid-range: The upper end, around IDR 120,000 for about 50GB. Good if you stream, share a hotspot, or work remotely.
• Comfortable: A Telkomsel tourist package. Prices run slightly higher than competitors, but you pay for the widest coverage if your route includes remote islands.

Exact prices and data sizes can change, so confirm the current package at the counter before you pay.

How to Buy and Register a Physical IM3 SIM, Step by Step

Step 1: Choose where to buy

• Airports: Official Indosat Ooredoo counters are at major international airports, including Soekarno-Hatta Jakarta (CGK) and Ngurah Rai Bali (DPS). This is the easiest option on arrival.



• Official stores (Gerai Indosat Ooredoo): Found in major shopping malls and city centres.
• Convenience stores: Indomaret and Alfamart often sell SIM cards. Activation and registration may need help from a dedicated counter or a self-service app, so do not count on finishing everything at the till.
• Pre-order: Some tour operators and third-party websites offer SIMs for airport pickup.

Step 2: Bring your documents

You need your original passport for registration. A photocopy or photo on your phone is not what staff expect.

Step 3: Register at the counter

1. Hand your passport to the staff.
2. They enter your passport details into the national registration system.
3. Your index fingerprint may be scanned for verification. Whether this is still standard in 2026 or replaced by a simple passport scan can vary, so do not be surprised either way.
4. The SIM is linked to your passport and activated.
5. You receive a copy of the registration confirmation. Keep it.

Step 4: Activate and test

1. Insert the SIM into your unlocked phone.
2. Restart the phone.
3. Look for an SMS confirming activation and your package details.
4. If nothing arrives, make a short call or send an SMS to trigger activation, or go back to the vendor.
5. Download the MyIM3 app to manage your plan.

At an airport counter with no queue, the whole process usually takes 5 to 15 minutes.

Setting Up an eSIM

Indosat Ooredoo has been expanding its eSIM offering, and by 2026 IM3 is expected to offer eSIMs to tourists. Telkomsel (through by.U), XL Axiata, and Smartfren are also expected to offer eSIMs as a standard option. Check availability on the provider’s site before you fly.

What you need

• An eSIM-compatible, unlocked smartphone
• An internet connection, such as airport WiFi, to download the profile

How to activate

1. Buy an eSIM package online or at an official store. For IM3, look at the official site (im3.id), the MyIM3 app, or a Gerai Indosat Ooredoo.
2. Receive a QR code by email or printed in the store.
3. On your phone, go to Settings > Cellular/Mobile Data > Add Data Plan or Add eSIM.
4. Scan the QR code.
5. Follow the prompts to activate and name the eSIM profile.
6. Switch data roaming OFF for your home SIM and ON for the Indonesian eSIM.

The big benefits: no tiny card to lose, and you can keep your home number active for calls and SMS while IM3 handles the data.

Checking Balance and Topping Up

Checking your plan

• MyIM3 app: Download it from Google Play or the Apple App Store and register with your IM3 number. It shows usage, balance, and package details.
• USSD code: Dial *123# and follow the menu for balance and package checks.

Adding more data

• MyIM3 app: The easiest way. Pay for data or credit with a credit or debit card.
• Convenience stores: Indomaret, Alfamart, and Circle K. Give your IM3 number and the amount or package, and pay cash.
• ATMs and online banking: Many Indonesian banks offer IM3 top-ups.
• Online vendors: Traveloka, Tokopedia, and Shopee, though these may need local payment methods or an account.
• Voucher cards: Less common now, but some smaller shops still sell them.

IM3 vs Telkomsel, XL Axiata, and Smartfren

IM3 is great value for Java and Bali. Its pricing is generally more attractive than Telkomsel’s main brand, and it still handles Gojek, Grab, and KAI Access well. But the right SIM depends on your route.

• Telkomsel (main brand and by.U): The widest and most reliable coverage in Indonesia, including many remote islands where others struggle. The main brand sells SIMPATI, Kartu AS, and Loop cards, with tourist packages at airports and official stores. by.U is the digital-first brand with customisable data packages and fully digital activation through the by.U app (byu.id), and it offers eSIM. Prices run slightly higher than competitors.
• XL Axiata: Excellent 4G/5G on Java and Bali, good in major cities on other islands, and slightly less extensive than Telkomsel in very remote areas. It offers competitive tourist packages with generous data, plus eSIM. See xl.co.id and the MyXL app.
• Smartfren: Mostly 4G/5G, but limited to urban and semi-urban areas. Very affordable data and an early eSIM pioneer in Indonesia. Best if your trip is city-only. See smartfren.com and the MySmartfren app.

Coverage by destination

• Java and Bali: Excellent across Telkomsel, Indosat Ooredoo, and XL Axiata. Smartfren is also fine in urban areas.
• Lombok and the Gili Islands: Good in Senggigi, Kuta Mandalika, and the main Gilis (Trawangan, Meno, Air) from Telkomsel, Indosat Ooredoo, and XL Axiata.
• Sumatra, Sulawesi, Kalimantan: Good in provincial capitals and larger towns, variable in rural areas. Telkomsel generally reaches furthest.
• Raja Ampat, Komodo National Park and Flores, Sumba: Highly variable. Telkomsel is almost always the best bet, but expect patchy or no service in very remote spots or at sea.

If you are heading deep into the east, carry a Telkomsel SIM or eSIM. If you are mostly in Java and Bali, IM3 is the sensible, cheaper choice.

Where WiFi Still Helps

WiFi is easy to find, so use it to save data when it works.

• Cafes, restaurants, and warungs: Most in urban and tourist areas offer free WiFi. Quality ranges from excellent to barely usable.
• Accommodation: Hotels, guesthouses, and villas almost always provide free WiFi, and speeds are generally good in mid-range and high-end places.
• Public WiFi: Less common and often less secure than in many Western countries. Do not rely on it for banking or anything important.

Use WiFi for big downloads, like offline maps or video calls, and keep mobile data for navigation, ride-hailing, and emergencies.

Common Mistakes to Avoid

• Forgetting your original passport. No passport, no registration. Keep it handy when you buy.
• Buying at a convenience store and assuming it is active. You may still need a counter or app step to register.
• Using a locked phone. Both SIMs and eSIMs need an unlocked handset. Check with your home carrier before you fly.
• Leaving roaming on for your home SIM. Switch it OFF, and turn data ON for the Indonesian line.
• Downloading the eSIM with no internet. You need a connection to install the profile, so scan the QR code on airport or hotel WiFi.
• Staying past 90 days with a foreign phone. After 90 days the phone is blocked on local networks unless the IMEI is registered and any taxes are paid.
• Expecting full coverage on remote islands. Download offline maps and tell people your plans before heading to places like Raja Ampat or Sumba.
