Indonesia sim card for tourists usually means a prepaid local SIM you buy on arrival, register with your passport, and top up for data and calls. For most new arrivals, an Indonesia SIM card is the cheapest and most reliable way to get online quickly, especially if you plan to use a lot of data or rely on apps for transport and payments.
Last updated: June 2026 — rules and prices change often; double-check close to your trip.
Quick definition: what “Indonesia SIM card for tourists” actually is
Most foreign visitors use a prepaid Indonesian SIM card in an unlocked phone. Key points:
- Prepaid only: Foreigners generally use prepaid (prabayar), not postpaid contracts.
- Passport registration: Your SIM must be registered to your passport at purchase; this is required by law.
- IMEI registration: If your phone is in Indonesia > 90 days, you may need to register its IMEI and pay import duty to keep mobile data working.
- Top-up system: You buy “pulsa” (credit) and data packages separately via shops or apps.
- Coverage varies: The best sim card in Indonesia for you depends on where you’ll spend most of your time, not just price.
This guide focuses on short- and medium‑term visitors (from a 10‑day holiday in Bali to a few months on a social/cultural or remote work visa), and how to stay connected legally and reliably.
Why you should get a local SIM instead of roaming
International roaming in Indonesia can work, but tends to be expensive or limited:
- Many Western carriers charge USD 5–15 per day for roaming packs (last verified June 2026).
- Fair use caps are common, so speeds may drop after a few GB.
- Some smaller carriers don’t have good roaming agreements outside Jakarta/Bali, so your coverage can be patchy.
By contrast, Indonesian prepaid data for tourists is relatively cheap:
- Data-only tourist packs: roughly IDR 100,000–250,000 for ~25–70 GB for 30 days (last verified June 2026).
- Combo packs (data+voice+SMS): roughly IDR 75,000–200,000 per 28–30 days for a moderate user.
If you’re working remotely or depending on maps, ride‑hailing, and WhatsApp to coordinate with accommodation and your banjar (local community) in Bali or elsewhere, a local SIM quickly pays for itself.
What you need to buy a SIM as a foreigner
Buying an Indonesia SIM card for tourists is straightforward if you know the rules.
Documents & registration
You will normally be asked for:
- Passport (original, not just a photo).
- Visa page or e‑visa if applicable (tourist, social, KITAS, etc.).
- A local contact number and address (hotel/Airbnb address is usually fine for short stays).
Indonesia requires real‑name registration of SIM cards. In an official store or a reputable counter at the airport, staff will:
- Scan your passport and/or take a photo.
- Register your details in the operator system.
- Activate the SIM and usually install it for you.
Avoid buying “pre-registered” SIMs from informal resellers who don’t register your passport; those cards can be deactivated without warning, leaving you locked out of banking or OTP codes.
Unlocked phone requirement
Your phone must be unlocked to use an Indonesian SIM. If your home carrier locks phones, ask them to unlock before travel. Without this, you’ll be stuck with roaming or Wi‑Fi only.
IMEI & 90‑day rule (important for longer stays)
Indonesia tracks device IMEI numbers for tax and anti‑theft reasons. Key points (general information only — verify with a customs or tax professional):
- Tourists staying up to 90 days can usually use foreign phones without paying import duties, but may need a simple IMEI registration at the airport for seamless service.
- Stays over 90 days and long‑term visas (KITAS, retirement, etc.) may require paying import duty on high‑value phones and registering the IMEI so the device remains fully usable on Indonesian networks.
- Unregistered devices may lose mobile data after the grace period, even if your SIM is valid.
Double‑check current thresholds and procedures with Indonesian Customs or a licensed consultant close to your travel date, as rules and enforcement can shift.
Best SIM card in Indonesia: which operator to choose?
No single provider is best for everyone. The right choice depends on:
- Where you’ll stay (Jakarta vs. rural Flores is very different).
- How data‑hungry you are (video calls, streaming, remote work).
- Whether you’ll move around multiple islands.
Below is a high‑level comparison of what you should look for among the major nationwide operators (names are widely known public information; specific package names change frequently and are not listed here).
| Factor | What to look for (June 2026) |
|---|---|
| Coverage in big cities | Most major operators offer solid 4G in Jakarta, Surabaya, Bandung, Medan, Denpasar. |
| Coverage for Bali & Java | Look for providers known for strong coverage in South Bali, Ubud, Canggu, and across Java’s main cities and highways. |
| Coverage in remote islands | Choose carriers highlighted (in recent, independent coverage tests) as better outside Java–Bali, especially for Sumatra, Kalimantan, Nusa Tenggara, Papua. |
| Tourist packages | Ask for “tourist” or “visitor” SIMs with large data quotas (20–70 GB) valid 30 days. |
| Price for 30 days data | Expect about IDR 100,000–250,000 for ~25–70 GB (data‑only or data‑heavy packs). |
| Hotspot/tethering | Most prepaid packs allow tethering, but some cheaper promo plans limit it; confirm before paying. |
| English support | Flagship stores in tourist areas and airports usually have at least some English‑speaking staff. |
For internet in Bali specifically:
- South Bali (Kuta, Legian, Seminyak, Canggu, Nusa Dua, Sanur) has strong 4G from most big providers.
- Ubud and central Bali are generally good, but black spots exist in valleys and rice‑field areas.
- North and West Bali can be patchier; if you plan to stay months in a remote villa, test several SIMs or rely more on fixed broadband.
Locals and long‑term expats often keep two SIMs from different networks (dual‑SIM phone) to hedge against outages and patchy coverage, especially if they move between Bali, Lombok, and other islands.
Where to buy an Indonesia SIM card for tourists
1. At the airport
Pros:
- Convenient after a long flight; English is usually spoken.
- Tourist packs are clearly advertised with 30‑day validity.
- Registration is handled on the spot.
Cons:
- Prices can be higher than in town, or include extra services you don’t need.
- Limited choice of providers and plans.
Expect to pay something like IDR 150,000–350,000 at major international airports for a 30‑day tourist SIM with a decent data allowance (last verified June 2026). You’re paying a premium for convenience and English‑speaking help.
2. Official operator stores in town
Pros:
- Best place to sort out problems, lost SIMs, or IMEI issues.
- Wider choice of plans, sometimes cheaper than airport bundles.
- Legitimate registration and receipts.
Cons:
- Staff English levels vary, especially outside Bali/Jakarta.
- Queues can be long at popular malls.
If you’re staying more than a month or plan to return often, it’s worth visiting a proper store within a few days of arrival to confirm registration details and pick a package that fits your usage.
3. Convenience stores & small kiosks
Mini‑markets and street kiosks (warung) often sell starter packs and “pulsa” top‑ups.
Pros:
- You’ll find these almost everywhere, including small villages.
- Quick top‑ups once your SIM is already set up.
Cons:
- Registration and activation help can be limited.
- Some sellers offer “already registered” SIMs under someone else’s ID; avoid these.
Use kiosks mainly for top‑ups after your SIM is properly registered via an airport booth or official shop.

How much should you budget for mobile data in 2025–2026?
Costs vary by operator and island, but here are realistic monthly ranges for tourists and new arrivals, last verified June 2026:
- Light user (messaging, email, maps)
- IDR 50,000–100,000 per 30 days for 5–15 GB.
- Standard user (social media, some video, rides, food apps)
- IDR 75,000–200,000 per 30 days for 15–40 GB.
- Heavy user / remote worker (video calls, cloud, streaming)
- IDR 150,000–350,000 per 30 days for 40–100 GB, or combining two SIMs.
- SIM starter pack
- Typically IDR 25,000–75,000 for the SIM itself, sometimes bundled with the first data pack.
- Airport tourist SIM bundle
- Often IDR 150,000–350,000 for SIM + 25–70 GB for 30 days.
To put that in perspective with other daily life costs (June 2026):
- A basic local meal: roughly IDR 25,000–50,000 in many cities.
- A grab‑style motorbike ride in South Bali: often IDR 10,000–40,000 for short distances.
So a month of solid data is in the same price band as a couple of meals out or a handful of transport rides — not a major cost driver of your relocation, but essential for organizing housing, healthcare, and immigration appointments.
eSIMs vs physical SIMs in Indonesia (2025–2026)
International travel eSIMs
Several global providers sell eSIM data packs usable in Indonesia. Pros:
- Install before flying; data works on landing.
- No local language issues.
- Good as a backup if you land late at night.
Cons:
- Typically more expensive per GB than local SIMs.
- Data‑only in most cases (no Indonesian number for OTP / calls).
A common strategy for frequent travellers:
- Keep home SIM in slot 1 for banking/OTP.
- Use an international eSIM for the journey and first 24 hours.
- Buy a local physical SIM the next day for long‑term use.
Local eSIM options
Major Indonesian operators have slowly started offering eSIM support, mostly in big cities and at flagship outlets. As of mid‑2026:
- Availability is improving but still not universal.
- Staff familiarity with eSIM setup varies by branch.
- Tourist‑friendly eSIM onboarding is still hit‑or‑miss compared to a simple physical SIM.
If your phone supports eSIM and you want a cleaner setup, ask in an official store in Jakarta, Denpasar, or a major mall; be prepared to fall back to a physical SIM if the process stalls.
Using your SIM for internet in Bali and across Indonesia
Signal realities in Bali
Tourist marketing makes it sound like Bali has infinite, perfect Wi‑Fi. The reality:
- South Bali (Kuta, Seminyak, Canggu, Nusa Dua, Sanur) has good 4G and decent home fibre in many streets, but power cuts and router issues still happen.
- Ubud has strong coverage on the main roads and co‑working hubs; once you head down into rice terraces or ravines, speeds can drop sharply.
- North/West Bali and small islands (Nusa Penida, Lembongan, parts of Lombok) can have patchy coverage and overloaded towers in high season.
Practical tips:
- Run a speed test in your villa or guesthouse before committing long‑term if you plan to work online.
- Keep at least one SIM from a different provider as backup for video calls.
- Have offline maps downloaded in case of network or power failures.
Tethering & hotspot use
Most Indonesia SIM card for tourists packages allow hotspot use/tethering, which is common for:
- Back‑up data when home Wi‑Fi drops.
- Working from cafés in Canggu or Ubud where the shared Wi‑Fi is overloaded.
Still, read the small print:
- Some low‑cost promo packs restrict hotspot or throttle it after a certain quota.
- Streaming and large downloads over hotspot will burn through your data surprisingly fast.
Internet for longer‑term stays
If you decide to stay in Indonesia for several months or years (on the appropriate visa and while respecting work and tax rules), relying only on mobile data gets limiting. Most long‑term expats in Bali and Java use:
- Fixed home broadband (fibre where available; wireless elsewhere) plus
- One or two mobile SIMs as backup and for outside use.
Installation fees and monthly broadband costs depend heavily on location and building type. As a rough orientation (June 2026):
- Basic home internet packages in cities start around the price of a couple of mobile data packs per month.
- Remote villas may rely on wireless providers, with variable speeds and higher pricing.
We cover long‑term connectivity, work‑from‑Bali realities, and tax/visa constraints in more detail on our main relocation guides at Moving to Indonesia and our sister sites.
SIM cards, banking apps, and Indonesian daily life
In practice, your Indonesian phone number does more than calls and data:
- Ride‑hailing & food delivery: Gojek and Grab accounts are tied to your phone number; OTP codes arrive via SMS or WhatsApp.
- Local banking & e‑wallets: Many Indonesian banks, as well as GoPay, OVO, and other wallets, use SMS for activation and login.
- Banjar and local community groups: In Bali especially, your banjar and landlord likely coordinate via WhatsApp groups; having a stable number helps you stay in the loop for ceremonies, road closures, and community dues.
If you later change numbers:
- Update ride‑hailing and delivery apps first so you don’t lose access.
- Notify landlords, schools, or helpers who rely on WhatsApp to reach you.
- Keep your old SIM active for a month or two (if possible) to catch stray OTPs.
Legal & practical cautions (read this before you rely on your phone)
This section is general information, not legal, immigration, or tax advice. Rules change, and enforcement can be inconsistent; always confirm with:
- Indonesia’s official immigration and customs channels, and/or
- A licensed immigration consultant or lawyer, and
- A qualified tax professional in both Indonesia and your home country if you plan to work or stay long‑term.
Key points:
- Tourist SIM ≠ right to work: Having an Indonesian number or fast internet does not give you the legal right to work in Indonesia. Paid work (including online work “for foreign clients only”) intersects with visa and tax rules — get licensed advice.
- IMEI & duties: Do not ignore IMEI or customs rules if you are staying long‑term. An unregistered device may suddenly stop getting mobile data, which can impact your access to banking and immigration apps.
- Data privacy: Treat your Indonesian number as semi‑public. Service providers, landlords, agents, and WhatsApp groups will all have it. Use strong app‑level security for banking and sensitive communications.
- Emergency services: Local emergency numbers (like 112 in many regions) can often be called even without credit, but coverage and response quality vary by area.
Getting personal help with connectivity and relocation
Sorting out an Indonesia SIM card for tourists is usually simple. The complications start when:
- You’re planning to base yourself in Bali or another island for 3–12+ months.
- You need stable internet for remote employment or a business.
- You’re trying to line up housing, schooling, and healthcare around your connectivity needs.

FAQs: Indonesia SIM card & internet for newcomers
Can tourists buy a SIM card at Bali airport easily?
Yes. At Denpasar (Ngurah Rai) Airport, you’ll find official counters from major operators in the arrivals area. Bring your passport, choose a 30‑day tourist package, and staff will register and activate the SIM for you. Prices are higher than in town, but it’s the most convenient option after a long flight.
Is it better to use an eSIM or physical SIM in Indonesia?
For short trips, an international eSIM is convenient but usually more expensive per GB and often data‑only. For stays beyond a week or two, a local physical SIM from a major Indonesian operator is usually cheaper and gives you an Indonesian number for OTPs and local services. Local eSIM options exist but are still less consistent than physical SIMs as of mid‑2026.
How much data do I need for 2 weeks in Bali?
Most visitors do fine on 10–20 GB for a 2‑week stay if they’re mainly using maps, messaging, social media, and some video. If you plan to work remotely, take video calls, or stream a lot, aim for 25–40 GB or buy a second data pack mid‑trip. Data packages are relatively inexpensive, so it’s safer to slightly over‑estimate.
Will my WhatsApp number change if I use an Indonesian SIM?
No, not automatically. WhatsApp can keep using your home number even if you insert an Indonesian SIM, as long as you don’t change the number in WhatsApp settings. Many expats keep their home number on WhatsApp for continuity, and use the Indonesian SIM only for data and local calls/SMS.
Can I rely on mobile data for remote work in Bali?
For short stays, many remote workers do rely mainly on mobile data, especially in South Bali and Ubud, and use hotspots when café or villa Wi‑Fi fails. For multi‑month stays, you’ll usually want a place with fixed broadband plus at least one strong mobile SIM as backup. Always test speeds in the exact house or coworking space you plan to work from before committing long‑term.
