From Arrival to Online: Getting Your Indonesia SIM Card Smoothly

You land in Jakarta or Denpasar after a long flight, your phone shows no signal, and you need a ride-hailing app to find your driver. Then you hear about IMEI registration, passport checks, and a 90-day rule, and it sounds more complicated than a SIM card should be. In 2026 it is much easier than it was a couple of years ago, but only if you know what to ask for and where to buy. This guide walks you through it.

Before You Land: Passport and IMEI Rules

Indonesia requires every mobile device using an Indonesian SIM to have its IMEI (International Mobile Equipment Identity) registered with the Ministry of Communication and Information Technology (Kominfo) and the Directorate General of Customs and Excise. The rules came in around 2020-2022 to stop illegal phone imports. As a tourist, you mostly need to know two things.

• Bring your original passport. Every foreign visitor must show it to register a SIM. A photocopy is usually not accepted.
• Know your IMEI. Dial *#06# on your phone to display it. Screenshot it in case the vendor asks.

The 90-Day Rule

Up to 90 days: When you buy a Tourist SIM or a standard prepaid SIM at an official kiosk (airport counters, official brand stores), the vendor normally handles the IMEI registration with Kominfo for you. Your foreign phone can then work with an Indonesian SIM for up to 90 days without import taxes. For short-term tourist use this is generally free, because it is part of the service.

Over 90 days: You must register your device’s IMEI with Indonesian Customs (Bea Cukai) and pay import taxes. You can do this at the customs counter at international airports or online at beacukai.go.id/register-imei.html. The tax is typically 10% VAT plus 7.5% Income Tax (PPh) on the value above USD 500 (about IDR 7,800,000 at IDR 15,600 per USD 1). A phone valued at USD 1,000 would be taxed on USD 500. Confirm the current rate and exemption limit on the Bea Cukai site before you pay.

If you do nothing: An unregistered or untaxed foreign device stops working with Indonesian SIM cards after about 90 days. It will still work with foreign SIMs and on WiFi.

Step-by-Step: From Arrival Hall to Online

After immigration and baggage claim, the international arrivals halls at Soekarno-Hatta (CGK), Ngurah Rai (DPS), and Surabaya (SUB) have official kiosks for Telkomsel, Indosat Ooredoo, XL Axiata, and Smartfren. Here is the quickest way through.

1. Switch your phone to airplane mode off and check it is unlocked. A phone locked to your home carrier will not accept a local SIM.
2. Walk to an official kiosk in the arrivals hall. The air conditioning is cold, the counters are busy with new arrivals, and staff usually speak workable English.
3. Hand over your original passport and tell them how many days you will stay and how much data you need.
4. Let the vendor register the SIM and your IMEI for the 90-day period. Ask them to confirm it is done before you leave.
5. Insert the SIM at the counter and ask staff to test data. Open a map or messaging app and confirm it loads.
6. Install the provider app (MyTelkomsel, myIM3, myXL, or Smartfren) so you can check your balance and buy more data later.
7. Order your Gojek or Grab ride while you are still near the airport WiFi, then head out.

Choosing Your Operator: Telkomsel, Indosat, XL and Smartfren

All four operators sell tourist-friendly prepaid plans. The plans below are examples of what is offered in 2026. Plans and prices change often, so treat them as a guide and confirm at the counter.

Telkomsel (and by.U)

Telkomsel has the widest and most reliable coverage in Indonesia, including many remote islands and rural areas. It is excellent on Java and Bali. The PraBayar prepaid SIM is sold at Telkomsel Grapari stores, airport kiosks, and authorised resellers. An example plan is the “Tourist Data Plan 30D” for IDR 150,000, with 25GB (15GB all-network, 10GB local data) valid for 30 days.

by.U is Telkomsel’s fully digital brand, run through its app and the website byu.id. The process works like this:

1. Download the by.U app from Google Play or the Apple App Store.
2. Pick a data package, for example 20GB for 30 days at IDR 80,000.
3. Enter your passport details in the app.
4. Choose delivery to your accommodation (Jakarta or Bali, 1-2 business days, fee about IDR 15,000) or pick-up at selected Indomaret or Alfamart stores or Telkomsel Grapari locations.
5. Activate the SIM in the app when it arrives.

Indosat Ooredoo (IM3)

Indosat is excellent in major cities and dense areas, especially on Java and Bali, and good in other provincial capitals. The IM3 PraBayar SIM is sold at Indosat Ooredoo Stores, airport kiosks, and resellers. An example is the “Tourist Freedom Plan” at IDR 120,000: 20GB on all networks, unlimited calls to IM3 numbers, valid for 30 days.

XL Axiata (and AXIS)

XL is very good in major cities and tourist areas (Java, Bali, Lombok) and improving elsewhere. You can buy at XL Centers, airport kiosks, and resellers. An example is “XL Go Tourist” at IDR 100,000: 18GB on all networks for 30 days. AXIS, XL’s youth brand, often has budget-friendly data packages.

Smartfren

Smartfren works well in urban areas and big cities but is less extensive in rural and remote regions. It focuses on data-heavy plans. An example is “Smartfren Travel Data 30D” at IDR 95,000: 25GB on all networks for 30 days. You can buy at Smartfren Gallery stores, airport kiosks, and resellers.

eSIM in 2026: Skipping the Plastic

If your phone supports eSIM, you can avoid the kiosk entirely. Smartfren was an early adopter and still offers eSIM widely for prepaid users. by.U now offers eSIM on select plans, activated through the app by scanning a QR code or entering details manually. Indosat Ooredoo and XL Axiata are expanding prepaid eSIM options for tourists, but availability varies, so check before you rely on them.

How to Activate a Smartfren eSIM

1. Visit a Smartfren Gallery or the official website, smartfren.com, and buy an eSIM plan.
2. Give your passport details for registration.
3. Receive a QR code, either printed or by email.
4. On your phone, open Settings, then Cellular or Mobile Data, and tap “Add Cellular Plan” or “Add eSIM.”
5. Scan the QR code.
6. Follow the on-screen prompts to finish.

The big advantage is that you can buy online before you fly and activate on arrival, so you can order a ride from the moment you land. Your home SIM also stays in the phone, so you keep your regular number for bank codes.

Buying Away From the Airport

If you have time after arrival, official brand stores give you the widest choice of plans and real customer support. Look for Telkomsel Grapari, Indosat Ooredoo Stores, XL Centers, and Smartfren Galleries in major cities and shopping malls. Airport prices can run about IDR 10,000-20,000 higher than at stores outside, so a city store is a small saving.

Indomaret and Alfamart sell physical SIM cards, but the full registration with passport and IMEI usually still has to be completed through the provider’s app or at an official store, even for tourists. Do not count on a quick in-store registration at a convenience store. The online route is the other option: by.U for physical SIM delivery or pick-up, and Smartfren for online eSIM purchase.

Topping Up Once You Are Connected

Indonesians call it isi ulang. You have four easy ways to do it:

• Provider apps: MyTelkomsel, myIM3, myXL, and Smartfren let you track usage, buy data packages, and pay by credit or debit card.
• Convenience stores: Give the cashier at Indomaret or Alfamart your phone number and the amount or package you want.
• E-commerce platforms: Tokopedia and Shopee both sell credit and data.
• Banking apps: Most Indonesian banking apps include top-up services.

For most trips under a month, one 30-day plan is enough. Top-ups matter more if you are working online or streaming.

Signal Strength Across the Archipelago

Excellent: Java, Bali, Lombok, major cities on Sumatra (Medan, Palembang, Padang) and Sulawesi (Makassar, Manado), and developed areas of Kalimantan (Balikpapan, Pontianak, Samarinda). Telkomsel is consistently the strongest here.

Good: Other provincial capitals, main inter-island ferry routes, and popular tourist routes such as Flores and parts of Sumatra’s interior. Indosat Ooredoo and XL Axiata generally perform well here.

Variable or limited: Remote islands, mountains, deep jungle, and very rural areas. Telkomsel is almost always the only provider with any signal, and even then it can drop to 2G or 3G. Specific examples:

• Raja Ampat: limited Telkomsel coverage, mainly around Waisai and some resorts.
• Komodo National Park: limited Telkomsel coverage, mostly around Labuan Bajo and some ranger posts.
• Mentawai Islands: limited Telkomsel coverage in main villages, almost none at the surf breaks.
• Mount Rinjani, Lombok: spotty, mostly Telkomsel at higher altitudes. A single bar of signal on a ridge at dawn may be all you get, so download offline maps first.

If your route includes any of these places, choose Telkomsel. If you are staying in cities and beach towns on Java and Bali, the cheaper operators will serve you well.

WiFi: Useful, but Not a Plan

Almost all hotels, guesthouses, villas, and many homestays offer free WiFi, though quality varies. Cafes and restaurants in urban and tourist areas commonly display “Free WiFi” signs, and speeds are usually fine for browsing and messaging. Some executive-class KAI trains offer free WiFi, but reliability is inconsistent. Gojek and Grab vehicles do not typically offer passenger WiFi. Free public WiFi outside specific venues is limited, so mobile data is generally more reliable.

Common Mistakes to Avoid

• Showing a passport photocopy. Bring the original.
• Buying a SIM at a convenience store and assuming it is registered. You may still need the provider’s app or an official store to complete registration.
• Skipping the data test. Confirm the connection works before you leave the counter.
• Using a locked phone. Unlock it with your home carrier before the trip.
• Ignoring the 90-day limit. Staying longer without registering with Bea Cukai and paying import tax means your phone stops working with Indonesian SIMs.
• Choosing the cheapest SIM for remote travel. Raja Ampat, Komodo, Mentawai, and Rinjani are Telkomsel territory.
• Relying on WiFi for navigation. Public WiFi outside venues is limited, so keep mobile data on for maps and ride-hailing.

Frequently Asked Questions

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

For stays up to 90 days, the vendor normally registers your IMEI when you buy a tourist or prepaid SIM at an official outlet, usually free. Bring your original passport. Beyond 90 days, you must register with Bea Cukai and pay import taxes, or the phone stops working on Indonesian SIMs.

Which Indonesian SIM card is best for tourists?

Telkomsel has the widest coverage, including remote islands, so it suits trips beyond Java and Bali. In big cities and main tourist areas, Indosat, XL, and Smartfren all work well and often cost less. Choose by itinerary: Telkomsel for remote areas, a cheaper operator for city and beach trips.

Can I use an eSIM in Indonesia in 2026?

Yes, if your phone is eSIM-compatible. Smartfren offers eSIM widely and you can buy it online at smartfren.com before arrival. by.U offers eSIM on select plans, and Indosat and XL are expanding theirs. Scan the QR code under Add Cellular Plan in your phone settings.

Can I buy a tourist SIM at Indomaret or Alfamart?

You can often buy the physical card there, but registration with your passport and IMEI usually still has to be completed through the provider’s app or at an official store. Airport kiosks and brand stores avoid that problem. Convenience stores are better for topping up credit and data packages.

What happens to my phone after 90 days in Indonesia?

If your IMEI has not been registered with Bea Cukai and taxed, the phone stops working with Indonesian SIM cards after about 90 days. It still works with foreign SIMs and on WiFi. The typical tax is 10% VAT plus 7.5% PPh on value above USD 500.
