When exploring a new country like Indonesia, staying connected is no longer just a convenience—it is an essential part of the modern travel experience. Whether you’re venturing through the remote jungles of Sumatra, island hopping in the Gili Islands, enjoying the beach clubs of Bali, or immersing yourself in cultural heritage in Yogyakarta, having mobile data at your fingertips makes travel smoother, safer, and much more enjoyable. If you’re also planning a trip to Cambodia or Vietnam, a reliable SIM card is just as essential.
This comprehensive guide will help you find the best SIM card in Indonesia for tourists. We will explore the top mobile network providers, where to buy your SIM, how to activate and register it, what type of packages are best suited for short- and long-term travel, and much more. With the right information, you can avoid connectivity issues, reduce your travel costs, and ensure that you are always just a click away from sharing your adventure or getting help when you need it.
Why Buying a SIM Card in Indonesia is a Smart Choice
Many travelers rely on public Wi-Fi to connect to the internet while abroad. However, in Indonesia, especially in remote or offbeat locations like Flores, the Mentawai Islands, or the outer provinces of Kalimantan and Papua, Wi-Fi coverage can be inconsistent or completely unavailable. Moreover, free public Wi-Fi networks can pose security risks, particularly when accessing sensitive information like your email, social media accounts, or online banking.
Purchasing a local SIM card offers a more reliable and secure connection. Here are the key benefits:
- You have full access to internet services, including maps, rideshare apps, translation tools, and travel bookings.
- Data plans are extremely affordable compared to international roaming charges.
- A local number makes it easier to communicate with tour operators, accommodation providers, and locals.
- With good coverage across islands, you won’t miss any updates from your group or travel company, even while on a multi-day trek or a boat trip.
For adventure travelers and backpackers who explore off-grid locations, a local SIM card is practically essential.
Leading SIM Card Providers in Indonesia
There are several mobile network providers in Indonesia, but not all offer the same level of service, coverage, or pricing. Below are the top four options that are generally considered the best for travelers:
Telkomsel
Telkomsel is Indonesia’s largest and most reliable mobile operator. It has the widest 4G LTE network coverage, including in rural and mountainous areas. If you are planning to travel extensively across different islands, Telkomsel is the best option for consistent connectivity.
- Strongest coverage nationwide, including remote islands.
- Best for longer trips, adventure travel, and off-the-beaten-path destinations.
- Reliable customer service and extensive support network.
- Slightly more expensive than competitors, but worth it for the reliability.
XL Axiata
XL Axiata is the second-largest provider and offers competitive pricing and good network coverage in cities and popular tourist regions. It is a great option for travelers who plan to stay mostly in urban areas such as Jakarta, Bali, Surabaya, or Bandung.
- Good 4G speeds in populated regions.
- Affordable data bundles.
- Slightly weaker in remote areas compared to Telkomsel.
- Excellent value for money for city explorers or short-term travelers.
Indosat Ooredoo
Indosat is well-suited for travelers on a tight budget. It offers low-cost packages and is user-friendly. However, coverage is not as extensive in more rural parts of Indonesia.
- Great value for basic internet use and calls.
- Best for tourists who are staying in central and coastal towns.
- Customer support can be limited in some areas.
- Coverage can be patchy outside of major cities.
Smartfren
Smartfren focuses more on digital users and offers flexible data plans, especially for urban-based travelers and digital nomads. However, it is not available in many parts of the country, especially rural zones.
- Works well in major cities like Jakarta, Surabaya, and Bali.
- Good for short stays and light users.
- Not suitable for travelers exploring multiple provinces.
- Offers daily and weekly plans that are cost-efficient.
Where to Buy a SIM Card in Indonesia
Getting a SIM card is easy and straightforward in Indonesia. Here are the most common places to purchase one:
- At International Airports: Upon arrival at airports like Ngurah Rai International Airport (Bali) or Soekarno-Hatta International Airport (Jakarta), you’ll find dedicated booths offering SIM cards. These are convenient but may be slightly more expensive than in local stores. Similarly, if you arrive at the Rann of Kutch Festival, you’ll find local options.
- Official Mobile Network Stores: Authorized stores located in cities and tourist hubs provide trusted services, including registration and setup assistance. They are ideal if you want personalized help.
- Convenience Stores and Mini-markets: Stores like Indomaret and Alfamart sell SIM cards and top-ups. However, you may have to activate and register the SIM yourself.
Important Note: Since 2018, all SIM cards in Indonesia must be registered with a valid passport. Staff at official stores and airport counters will typically assist you with this process. If you attempt to buy a SIM from a kiosk or mini-market, make sure the staff can register it for you, or you risk the SIM being non-functional.
What Types of Plans Should Tourists Choose?
Every mobile network provider in Indonesia offers multiple data packages, depending on your needs and the duration of your stay. Here is an overview of typical offerings:
- Telkomsel: Offers 10 GB data plans valid for 30 days at around 120,000 Indonesian Rupiah.
- XL Axiata: Provides 15 GB data plans with 30-day validity for approximately 100,000 Rupiah.
- Indosat: Includes 8 GB of data and local call minutes at around 90,000 Rupiah for 30 days.
- Smartfren: Offers unlimited data plans with fair usage limits, often valid for 7 days, at prices starting from 75,000 Rupiah.
These packages are affordable and offer good value for most travelers, much like the SIM card plans in Thailand.
What About eSIM Options?
If your phone supports eSIM (embedded SIM), you can consider activating your plan before arrival in Indonesia. eSIM services are especially popular among tech-savvy travelers and frequent fliers.
Popular eSIM providers include:
- Airalo
- Nomad
- Holafly
These services let you choose and activate a plan without needing to buy a physical SIM. However, eSIMs tend to be slightly more expensive than local prepaid cards bought in-store. For short trips or travelers who want minimal hassle, this is a great option.
Helpful Tips for Using SIM Cards in Indonesia
- Always ensure your phone is unlocked before traveling. If it is carrier-locked, it may not accept international SIMs.
- Monitor your data usage to avoid unexpected top-ups. Most providers have mobile apps to help you track your consumption.
- Save the customer support number of your provider in case you face network issues.
- Carry a SIM ejector pin or a small paperclip to swap SIMs easily.
- When heading into remote or jungle areas, download offline maps via Google Maps or Maps.me.
- Use mobile hotspots if you are traveling with a group to share data across multiple devices.
- In case of emergency, you can dial 112, the national emergency number, even without credit on your SIM.
