Best SIM Cards in Indonesia for Expats: Telkomsel vs XLSMART vs Indosat Compared (Update 2026)

Choosing a SIM card in Indonesia for Expats is not just about price. It is about staying connected for work, travel, and daily life. In 2026, three main providers dominate the market. Telkomsel offers the most reliable nationwide coverage, making it ideal for travel and remote areas. XLSMART, following its April 2025 merger, provides strong value for city users. Indosat IM3 remains a solid budget option, especially in Jakarta and Bali.

Why Your SIM Choice Matters in Indonesia

Indonesia is a vast archipelago of more than 17,000 islands. Network quality varies enormously between the business districts of Central Jakarta and a remote beach in Lombok, or between Canggu’s café strip and a highland village in Flores. Picking the wrong provider based purely on price can mean dead zones at the exact moment you need to confirm a Gojek pickup, authenticate an Indonesian bank transfer, or join a client call from your villa in Ubud.

For expats relocating to Jakarta or settling in Bali, your SIM card is also tied to your NIK registration, your banking OTP system, and your BPJS enrollment. It is not a trivial choice. And in 2025, the Indonesian telecom market changed significantly: XL Axiata and Smartfren officially merged in April 2025 to form PT XLSMART Telecom Sejahtera Tbk (XLSMART), reshaping the competitive landscape. This guide reflects that update.

The Three Main SIM Providers in Indonesia (2026)

1. Telkomsel (SIMPATI)

Telkomsel is Indonesia’s largest mobile network operator, holding the biggest subscriber base and the widest physical network footprint in the country. In May 2025, commemorating its 30th anniversary, Telkomsel unified all its prepaid brands back under the original SIMPATI name, ending the Telkomsel Prabayar branding it had used since 2021.

Based on Ookla Speedtest data for Q1-Q2 2025, Telkomsel swept three national awards: Fastest Mobile Network, Best Coverage, and Best 5G. It is the undisputed leader for network reliability across all of Indonesia’s major islands, including remote areas of Kalimantan, Sulawesi, Maluku, and Papua where other operators have limited or no coverage.

• Tourist SIMPATI pack: IDR 150,000 (approximately 9 USD) for 25GB data and calls, valid 30 days
• eSIM available from official GraPARI stores and the Telkomsel website
• Maximum 3 SIM registrations per person
• Best for: island hopping, travel to remote areas, professionals who cannot afford connectivity gaps

2. XLSMART (XL Axiata + Smartfren Merged)

On April 17, 2025, XL Axiata and Smartfren completed their merger to become XLSMART. This is the most significant structural change in Indonesian telecoms in years. The combined entity now operates a significantly expanded 4G network across both urban and semi-rural areas, with ongoing integration of Smartfren’s spectrum assets into XL’s existing infrastructure.

XLSMART continues to offer SIM products under both the XL and Smartfren brand names during the transition period, with their Starter Packs offering competitive value:

• XL Starter Packs: IDR 35,000 to IDR 745,000 for 3GB to 50GB data, valid 45 to 60 days
• Plans include 1GB roaming data for countries including India, Malaysia, Japan, Australia, UAE, and the USA
• eSIM available from official XL stores and online
• Best for: city-based expats in Jakarta (Sudirman, SCBD, Kemang), budget-conscious data users

3. Indosat Ooredoo Hutchison (IM3)

Indosat Ooredoo Hutchison (IOH), operating its prepaid products under the Freedom (IM3) brand, is Indonesia’s second-largest operator by market share at approximately 22%. The 2022 merger of Indosat Ooredoo and Tri Indonesia has continued to mature, and in 2025 Indosat has become statistically tied with Telkomsel for data speed in major urban centers including Jakarta, Surabaya, and Denpasar.

For city-based expats focused on data volume at lower prices, Indosat is compelling:

• Freedom tourist packs: IDR 100,000 (approximately USD 6.40) for 30GB data with 10 international call minutes, valid 30 days
• IDR 200,000 (approximately USD 12.80) for 80GB data with 30 international call minutes, valid 30 days
• Plans include 1GB roaming data for India, Malaysia, Japan, Australia, UAE, and USA
• eSIM available from official IM3 stores
• Best for: urban expats in Jakarta and Bali who prioritise data volume over remote coverage

Side-by-Side Comparison: Telkomsel vs XLSMART vs Indosat IM3

Coverage by Island: Where Each Provider Performs

Java: Jakarta, Bandung, Surabaya

Java has Indonesia’s most developed telecom infrastructure. All three providers deliver strong 4G coverage across major cities, with 5G already active in parts of Jakarta, Surabaya, and Bandung. In the business districts of Sudirman, SCBD, Thamrin, and Kemang, expats will find reliable high-speed connectivity from any of the three operators. Price and data volume become the primary differentiators here rather than coverage quality.

Bali and Lombok

Bali’s tourism economy has driven strong telecom investment across the island. All three providers work well in Seminyak, Canggu, Ubud, Kuta, and Jimbaran. Telkomsel maintains an edge in less-visited areas such as the north coast, Amed, and the Nusa islands. XLSMART and Indosat deliver excellent speeds in the main tourist corridors. For digital nomads based in Canggu or Ubud and rarely traveling off-island, Indosat or XLSMART offers better data value. For anyone island-hopping to Lombok, Flores, or the Gilis, Telkomsel is the safer choice.

Sumatra, Kalimantan, and Eastern Indonesia

Outside Java and Bali, Telkomsel becomes the increasingly clear choice. Major cities in Sumatra such as Medan and Palembang have multi-operator coverage, but rural Sumatra and Kalimantan are predominantly Telkomsel territory. In Sulawesi, Maluku, and Papua, including energy, mining, and infrastructure project sites, Telkomsel is often the only reliable option. Expats working in these sectors should treat Telkomsel as the default choice regardless of the price premium.

Which SIM Cards Is Best for Expats in Jakarta?

For expats based in Jakarta’s central districts, including Sudirman, SCBD, Thamrin, Kemang, and Menteng, all three providers deliver comparable day-to-day performance. The decision typically comes down to budget and usage habits:

• Telkomsel SIMPATI: choose this if you travel frequently across Indonesia or outside Jakarta, rely heavily on uninterrupted connectivity for remote work, or want the most stable 5G in areas like Sudirman where coverage is strongest.
• XLSMART: choose this if you are primarily Jakarta-based, want larger data packages at lower cost, and do not regularly travel to remote areas of the archipelago.
• Indosat IM3: choose this if maximum data volume at the lowest monthly cost is your priority, and you stay mainly within the greater Jakarta and Java urban network.

Many experienced Jakarta expats use two SIMs: a primary Telkomsel SIM for calls, banking OTPs, and reliability, and a secondary Indosat or XLSMART SIM loaded with a large data package for everyday browsing, apps, and streaming.

Best SIM for Bali Digital Nomads and Remote Workers

Bali’s digital nomad community in Canggu, Seminyak, Ubud, and Berawa is large enough that all three major carriers have invested in solid infrastructure across the main nomad areas. For remote workers who stay within these corridors, Indosat IM3 offers the most data for the price, and its urban speeds in 2025 are competitive with Telkomsel in these locations.

For nomads who travel between Bali and other Indonesian islands, including Lombok, the Gili islands, Flores, or Sumba, Telkomsel is the only provider that delivers consistently usable connectivity across that level of geographic spread. The price premium is real but so is the coverage gap.

A practical approach used by many long-stay Bali nomads: purchase a Telkomsel SIMPATI SIM for travel periods and activate a separate Indosat or XLSMART eSIM for high-data periods at home base. With eSIM-capable dual-SIM phones, switching between the two is seamless.

Where to Buy a SIM Card in Indonesia for Expats

• Airports: Official carrier booths at Soekarno-Hatta Terminal 3 (Jakarta) and Ngurah Rai (Bali) sell SIM cards immediately on arrival. Airport pricing is slightly higher than city stores but the convenience is worth it for immediate connectivity.
• Official carrier stores: GraPARI (Telkomsel), XL Center, and Indosat stores in major malls and business districts offer the widest plan selection, proper registration support, and eSIM activation assistance.
• Convenience stores: Indomaret and Alfamart stock physical SIM cards, but plan selection is limited and registration may require a separate step using a short code.
• Online before arrival: Telkomsel’s SIMPATI Tourist Pack can be pre-ordered for pickup at selected GraPARI locations including Bali and Jakarta airports.

All SIM card purchases require passport registration. Official carrier stores handle this on the spot. For long-stay expats with a KITAS, registration at an official store also aligns your SIM with your NIK, which is required for banking OTP systems.

eSIM Options for Indonesia: Should You Use One?

eSIM adoption in Indonesia has grown rapidly in 2025 and 2026. All three major carriers now offer local eSIMs from their official stores and websites. For expats, the main advantage of a local carrier eSIM is the ability to maintain a physical SIM in one slot for a home-country number while using the Indonesian eSIM for local data and calls.

For tourists and short-stay visitors, international eSIM providers are a popular alternative:

• Jetpac: runs on Telkomsel’s network, offering 20GB for approximately USD 21 and 50GB for USD 25. Currently rated as the best value international eSIM for Indonesia in 2026.
• Holafly: runs on Indosat or XL networks, offering unlimited data plans with fixed validity periods. Best for heavy users who want unlimited without worrying about data caps.
• Airalo: runs on the Indotel network (Telkomsel-based infrastructure), with plans from USD 4.50 for 1GB. Reliable and widely used across Southeast Asia.

For expats on KITAS who need a number for banking OTPs and official registrations, international eSIMs are not a substitute for a locally registered SIM. Local eSIMs from official carriers are the correct solution for long-stay residents.

Match Your Provider to Your Lifestyle

There is no single best SIM card for every expat in Indonesia. The right choice depends on where you live, how often you travel across the archipelago, how much data you use, and whether remote-area connectivity is a requirement or a luxury. The table below summarises the decision:

• Telkomsel SIMPATI: best for reliability, island hopping, remote areas, and professionals who cannot afford connectivity gaps.
• XLSMART: best for city-based expats in Jakarta who want competitive data pricing following the 2025 XL and Smartfren merger.
• Indosat IM3: best for urban users in Jakarta and Bali who want maximum data volume at the lowest cost.

Many experienced expats use two SIMs in a dual-SIM phone to combine Telkomsel’s reliability with Indosat or XLSMART’s data value. With eSIM now available from all carriers, switching between providers has never been more flexible.

FAQ: SIM Cards in Indonesia for Expats (2026)

Q: Which SIM card is best overall for expats in Indonesia?

Q: What happened to XL Axiata and Smartfren?

On April 17, 2025, XL Axiata and Smartfren merged to become PT XLSMART Telecom Sejahtera Tbk. The combined entity now operates under both XL and Smartfren branding during a transition period. Coverage and plan pricing remain broadly the same as pre-merger XL Axiata, with expanded spectrum from Smartfren’s network being integrated progressively.

Q: Can tourists buy SIM cards in Indonesia?

Yes. Tourist SIM cards are available at airports, official carrier stores, and convenience stores. A passport is required for registration. Physical SIM cards and local eSIMs are both available from official carrier outlets.

Q: Which provider has the best coverage in Bali?

Telkomsel has the widest and most consistent coverage across Bali, including areas outside major tourist zones. Indosat and XLSMART are competitive in Canggu, Seminyak, Ubud, and Kuta, but signal can become inconsistent in more rural or northern areas of the island.

Q: Can expats get postpaid plans in Indonesia?

KITAS registration aligns your number with your NIK, which is required for postpaid applications at official stores.

Q: Is internet speed good in Jakarta and Bali?

Yes. Jakarta’s central districts (Sudirman, SCBD, Thamrin, Kemang) and Bali’s main areas (Canggu, Seminyak, Ubud) have strong 4G speeds with expanding 5G coverage from Telkomsel and increasingly from Indosat. Based on Ookla Q1-Q2 2025 data, Telkomsel is ranked the fastest mobile network in Indonesia.

Q: How many SIM cards can I register in Indonesia?

Telkomsel allows a maximum of 3 SIM registrations per person. Other carriers have similar registration limits linked to your passport or Indonesian ID. Registration at official stores is always recommended to ensure your SIM is properly linked to your identity documentation.
