You land at Soekarno-Hatta or Ngurah Rai, the humid air hits you, and you need a Gojek or Grab ride, a map, and a message to your hotel. Then you remember you never sorted out data. Roaming from home can cost a fortune. A local SIM raises questions about passports, phone registration, and whether your device will get blocked. In 2026 the good news is that you have more eSIM choices than ever. This guide reviews the main providers, explains the registration rules, and shows you how to activate without stress.
How the IMEI Registration Rule Shapes Your Choice
Indonesia regulates phones with foreign IMEI numbers under Peraturan Menteri Kominfo No. 1 Tahun 2020. The rule has been in effect since 2020. It matters because it decides where you can buy a local SIM or eSIM and how fast you get Connected.
For short-term tourists, typically up to 90 days, the process is simple. You buy a physical SIM or eSIM from an official store: Telkomsel Grapari, IM3 Store, XL Center, or Smartfren Store. The staff register your passport details and your phone’s IMEI on the spot. The registration covers that specific SIM or eSIM and its validity period, often 30, 60, or 90 days. You do not need to register with Indonesian customs (Bea Cukai) or pay import tax on your phone for short-term tourist use. The provider handles the temporary registration.
The long-stay rule is different. If you plan to use an Indonesian SIM for more than 90 days, your IMEI must be registered with Bea Cukai and import duties paid. Otherwise your phone will be blocked from local networks after about 90 days. The process is complex, and most short-term visitors never need it.
What Changed Since 2024: eSIM Is Now Mainstream
Until late 2023, Smartfren was virtually the only local provider offering eSIM to prepaid customers. That has changed. Telkomsel, Indosat Ooredoo Hutchison (IM3), and XL Axiata all launched widespread eSIM for prepaid and tourist plans in late 2023 and early 2024. Tourists now have real choice.
Other 2026 changes are smaller but useful:
- Registration is standardised. The law is the same, but staff at official stores now apply it consistently. Expect them to ask for your physical passport and scan your IMEI. It typically takes 5-10 minutes.
- 5G keeps growing. Telkomsel, IM3, and XL continue to expand 5G, mostly in major urban centres. 4G is still the standard almost everywhere.
- Prices have crept up slightly. Expect small inflationary increases compared with 2024. No major tourist SIM options have been discontinued. Packages simply evolve with new data allowances and validity periods.
Telkomsel and by.U eSIM Review
Telkomsel is the market leader. It has the most extensive and reliable coverage in Indonesia, including many remote areas, and it is generally considered the premium provider.
Getting a Telkomsel eSIM as a tourist
- Visit an official Grapari customer service centre. You will find them in major cities, large shopping malls, and international airports including CGK and DPS.
- Bring your original passport and your eSIM-compatible phone.
- Staff scan your passport and your phone’s IMEI.
- Ask for a “Telkomsel PraBayar Tourist Card” or “Telkomsel Tourist SIM Card” and say you want it as an eSIM.
- Staff generate a QR code. Scan it with your phone to install the profile.
As of late 2024, in-store was the main way for tourists to get a Telkomsel eSIM. Check www.telkomsel.com for any newer online option. You manage your plan in the MyTelkomsel app.
by.U: Telkomsel’s digital brand
by.U is fully app-based, with flexible, customisable data plans. It was an early eSIM adopter, well before the main Telkomsel brand. The problem for tourists is setup. You download the by.U app, choose “Pesan SIM Card,” then “eSIM.” Registration often asks for a local Indonesian address, which is a real hurdle if you have no local contacts. The QR code is then emailed to you. by.U suits longer stays or travellers with local connections, not airport arrival. Details are at www.byu.id, and you manage it in the by.U app, not MyTelkomsel.
IM3 and XL Axiata eSIM Review
IM3 (Indosat Ooredoo Hutchison) is the second-largest provider. It offers competitive pricing and good coverage, strongest in Java, Bali, and major cities on other islands. Go to an IM3 Store or Gerai Indosat with your passport and phone. Staff scan both, then you ask for an “IM3 Tourist SIM Card” or “Freedom Internet Tourist” package as an eSIM. They give you a QR code to scan. Manage your plan in myIM3 (www.indosatooredoo.com or www.im3.id).
XL Axiata has good coverage, especially in urban areas and popular tourist destinations, and is known for competitive data packages. Visit an XL Center, hand over your passport, let staff scan your IMEI, and ask for an “XL Tourist SIM Card” as an eSIM. Some “XL PRIORITAS Tourist” plans may also be available. Manage it in myXL (www.xl.co.id).
For both providers, in-store was the primary tourist method as of late 2024. If you want an online option, check their websites before you fly.
Smartfren eSIM Review: The Easiest Tourist Route
Smartfren runs an LTE-only (4G/5G) network and often has very competitive prices. Its coverage is strong in major cities but thinner than Telkomsel, IM3, or XL in remote areas. It was the pioneer of eSIM in Indonesia, and it is still the most tourist-friendly for one reason: you can buy online.
- Go to www.smartfren.com and find the “eSIM” or “Tourist eSIM” section.
- Choose your data plan.
- Complete online registration and upload an image of your passport.
- Pay online with a credit or debit card.
- Receive the QR code by email, usually almost instantly.
- Scan the QR code with your phone.
You can do this before you fly or right after landing, with no store visit. You can also buy at a Smartfren Store. Manage your plan in the MySmartfren app.
Global eSIM Providers: When Roaming Plans Make Sense
Airalo, Holafly, Nomad, Gigsky, and similar providers sell data-only eSIMs that roam on local networks, typically Telkomsel, Indosat, or XL.
- Pros: You buy and install everything online before departure. You are connected the moment you land. They typically bypass the local IMEI registration. Your home SIM stays active in a dual-SIM setup.
- Cons: They cost more per GB than local plans. They are data-only, so you get no Indonesian phone number. That can complicate Gojek or Grab sign-up if you do not already have an account. You cannot top them up with local vouchers.
Use them for short trips or as a backup. For longer stays or heavy data use, a local eSIM or physical SIM is usually cheaper.
2026 eSIM Budget Reality
All figures below are indicative 2026 prices in IDR. Expect minor changes from inflation and competition.
Budget
- Smartfren Tourist eSIM, 15GB, 14 days: IDR 50,000 – IDR 70,000
- Smartfren Tourist eSIM, 30GB, 30 days: IDR 80,000 – IDR 120,000
- by.U example plan, 30GB for 30 days: IDR 70,000 – IDR 100,000 (needs a local address)
Mid-range
- XL Tourist Card, 20GB, 30 days: IDR 70,000 – IDR 110,000
- IM3 Tourist Card, 20GB, 30 days: IDR 75,000 – IDR 120,000
- XL Tourist Card, 35GB, 30 days: IDR 120,000 – IDR 180,000
- IM3 Tourist Card, 40GB, 30 days: IDR 150,000 – IDR 200,000
Comfortable
- Telkomsel Tourist Card, 25GB, 30 days: IDR 100,000 – IDR 150,000
- Telkomsel Tourist Card, 50GB, 30 days: IDR 200,000 – IDR 250,000
Telkomsel costs more, but you are paying for the widest coverage. Global eSIMs usually cost more per GB than all of the above. Airport counters may also charge slightly more than city stores.
Step-by-Step eSIM Activation and Troubleshooting
Before you buy anything, check two things. First, your phone must support eSIM. Most flagships from 2018 onwards do, including iPhone XR/XS and newer, Samsung Galaxy S20 and newer, and Google Pixel 3 and newer. Second, your phone must be unlocked by your home carrier.
- Connect to stable Wi-Fi.
- Open Settings and go to “Cellular” or “Mobile Data.”
- Tap “Add Cellular Plan” or “Add eSIM.”
- Choose “Use QR Code.”
- Scan the QR code from the staff screen, a printout, or another device.
- Label the eSIM and set it as your primary data line if you want.
If scanning fails, choose “Enter Details Manually.” You will need the SM-DP+ Address and Activation Code, which usually come with the QR code. If you have no data after activation, check the APN settings. They usually configure automatically, but if not, look up the provider’s correct APN. “internet” is common. A simple restart fixes many minor glitches. If problems persist, contact the provider’s customer service.
Coverage and WiFi: What to Expect from Java to Papua
Java and Bali have excellent 4G and growing 5G in nearly all populated areas. That includes Jakarta, Surabaya, Bandung, Yogyakarta, Denpasar, and popular tourist hubs. Telkomsel, IM3, and XL all perform well there.
On Sumatra, Kalimantan, and Sulawesi, coverage is strong in provincial capitals like Medan, Makassar, and Balikpapan and along main transport routes. It gets more variable in rural areas and smaller towns. Lombok and Flores, including Labuan Bajo near Komodo National Park, have good coverage in main towns and tourist areas, but it can be patchy in remote villages and at sea.
Remote islands, mountain regions, Papua, and Maluku can have very limited coverage, sometimes only 2G/3G or nothing. Telkomsel generally offers the widest reach there. Smartfren’s LTE-only network may struggle where 4G infrastructure is missing.
Wi-Fi is common. Almost all hotels, guesthouses, and many homestays offer free Wi-Fi, though quality ranges from basic to very fast. Urban cafes, restaurants, and malls usually have speeds that are fine for browsing and messaging. Public Wi-Fi is less reliable and less secure, so avoid banking on it. Mobile data gives you consistent, safer connectivity for navigation and ride-hailing.
Where to Buy, Top Up, and Which Apps to Install
- Airports: Convenient on arrival at CGK and DPS. Look for official Telkomsel, IM3, and XL counters. Prices may be a little higher.
- Official stores: Grapari, IM3 Store, XL Center, and Smartfren Store offer the best service, plan choice, and eSIM activation.
- Minimarkets and resellers: Physical SIMs may be sold here, but they can require self-registration through an app, which is hard for tourists. For eSIMs, stay with official stores or buy directly online from the provider.
Cash in IDR is always accepted, and cards are common in official stores.
To top up, use the provider apps: MyTelkomsel, myIM3, myXL, or MySmartfren. This is the easiest method. Other options include Indomaret and Alfamart (give the cashier your number), some ATMs, and Tokopedia or Shopee, though those can need local payment methods.
Install these before you start exploring:
- Gojek and Grab: For ride-hailing, food delivery, and more. Registration needs an active phone number, either a local one or an international number you registered before arriving.
- KAI Access: For booking Kereta Api Indonesia train tickets across Java.
- Your provider’s app: To check balance, track data, and buy more.
Common Mistakes to Avoid
- Arriving with a locked phone. A carrier-locked device will not accept a new eSIM.
- Forgetting your physical passport. A photo is not enough. Staff need the original for IMEI registration.
- Choosing by.U at the airport. The local address requirement often blocks tourists.
- Buying a minimarket SIM and hitting self-registration. It can be confusing without a local ID.
- Installing the eSIM with no Wi-Fi. You need a stable connection to download the profile.
- Picking Smartfren for remote islands. Its coverage is weaker there. Telkomsel is the safer bet.
- Ignoring the 90-day limit. A longer stay needs IMEI registration with Bea Cukai and import duties, or your phone is blocked.
- Relying on public Wi-Fi for payments. Use mobile data for sensitive transactions.
Frequently Asked Questions
Can tourists buy a local eSIM online in Indonesia?
Smartfren is the easiest option. You buy on www.smartfren.com, upload a passport image, pay by card, and receive the QR code by email almost instantly. Telkomsel, IM3, and XL mainly sell tourist eSIMs in-store, where staff register your passport and IMEI. by.U needs a local address, so it suits tourists poorly.
Do I need to register my phone with customs as a tourist?
No, not for short-term use. The provider registers your passport and IMEI at the point of sale for the SIM’s validity, often 30, 60, or 90 days. Only if you use an Indonesian SIM for more than 90 days must you register with Bea Cukai and pay import duties, or your phone gets blocked.
Which phones support eSIM in Indonesia?
Most flagship phones from 2018 onwards work, including iPhone XR/XS and newer, Samsung Galaxy S20 and newer, and Google Pixel 3 and newer. Your phone must also be unlocked by your home carrier. Check both before you travel, because a locked phone will not accept a new eSIM profile.
Which provider has the best coverage across Indonesia?
Telkomsel has the most extensive and reliable coverage, including many remote areas, so it is the safest choice for Papua, Maluku, and remote islands. On Java and Bali, Telkomsel, IM3, and XL all work well. Smartfren’s LTE-only network may struggle where 4G infrastructure is missing.
Is a global eSIM better than a local one?
Global eSIMs from Airalo, Holafly, Nomad, or Gigsky work instantly and skip local registration, but they cost more per GB and give no Indonesian phone number. They suit short trips or backup. For longer stays or heavy data use, a local eSIM or physical SIM is usually cheaper.
