Find the right SIM for me
Three quick questions and we'll show you the best operator and plan for your trip.
Prices are estimates based on average 2026 rates. Actual prices vary by seller and location.
Bali has three big mobile operators. Coverage and pricing are roughly comparable in cities, but they differ significantly in rural and remote areas.
| Operator | Coverage strength | Tourist SIM price | Best for | Tourist SIM at airport |
|---|---|---|---|---|
| Telkomsel | Best nationwide, especially rural and mountainous areas | $10–$25 | Travelers heading to the Nusa islands, the northern highlands, the Gilis, or on long multi-area trips | Yes |
| XL Axiata | Strong in cities and popular tourist areas | $7–$20 | Travelers based in the south and Ubud — Kuta, Seminyak, Canggu, Sanur, Ubud, Nusa Dua | Yes |
| Indosat | Strong in major cities, good tourist areas | $7–$18 | Budget travelers staying in big cities — often slightly cheaper plans | Limited |
You have four main options, each with its own tradeoffs.
The easiest option. Bali's Ngurah Rai International Airport (Denpasar) has official Telkomsel, XL Axiata and Indosat counters in the arrivals hall. You pay a small premium (usually $3–5 more than town prices) but get a working, registered SIM in under 10 minutes with English-speaking staff. Best for short trips when you don't want to hunt for a store after landing.
Telkomsel, XL Axiata, and Indosat all have stores in every Balinese city. Prices are lower than the airport, you can choose from the full plan range, and topping up is simple. Bring your passport — staff will register the SIM. Best for trips longer than two weeks or anyone who wants a non-tourist plan with better data value.
Small shops sell SIM cards everywhere, often at half the airport price. The risk: SIMs sold this way are sometimes not properly registered to your passport, which can mean the SIM gets deactivated mid-trip. If you go this route, insist the seller registers the SIM with your passport in front of you. Otherwise, an official operator store is safer.
Buy a travel eSIM from a provider like Airalo, Holafly, or Nomad before you fly. Activate it before you land and have data the moment your plane touches down. Slightly more expensive than a local SIM, but zero queuing, zero passport paperwork, and zero risk of buying a bad SIM. Telkomsel and XL Axiata also offer eSIMs directly for compatible phones.
Both work well in Bali. The right choice depends on your phone, your trip length, and your priorities.
Plan availability changes regularly. These are the most consistent tourist-friendly plans across the three major operators.
Most tourist SIMs are pre-activated when you buy them. If you bought a standard SIM at a store, follow these steps to get connected.
For eSIMs, scan the QR code sent by your provider in Step 1 instead of inserting a physical SIM.
Use a SIM ejector tool or a paperclip to open your phone's SIM tray. Insert the new SIM (face it the right way) and slide the tray back in. For eSIMs, scan the QR code your provider sends to your email.
Turn your phone off and on again. This forces it to register with the Balinese network. Within a minute or two you should see "Telkomsel," "XL Axiata," or "Indosat" appear as your carrier name.
In Settings → Mobile Data (or Cellular), make sure mobile data is on. If you're using dual SIM, set the Balinese SIM as the data SIM. Disable data roaming on your home SIM to avoid accidental charges.
Open a browser or maps app to confirm data is working. If it doesn't activate within 10 minutes, check the APN setting — usually internet (Telkomsel), internet (XL Axiata), or indosatooredoo (Indosat). The SIM usually configures this automatically.
Your new number is usually printed on the SIM card holder or sent by SMS. Save it in your contacts — you'll need it for Grab rides, food delivery apps, hotel check-ins, and calling local restaurants or guesthouses.
All three Indonesian operators offer excellent 4G coverage across the main tourist areas — Kuta, Seminyak, Canggu, Sanur, Nusa Dua, Uluwatu and Ubud are all very well served. 5G is rolling out in parts of Denpasar and the south, with Telkomsel leading. For most travelers, 4G speeds across these areas are more than fast enough for streaming, video calls, and hotspot use.
Away from the south, coverage varies. Telkomsel has the strongest reach by a wide margin — if you're heading to the Nusa islands (Penida, Lembongan), the Gili Islands, the northern highlands around Kintamani and Munduk, or remote beaches, Telkomsel is the safest choice. XL Axiata and Indosat work well in the popular areas but can drop out in quieter, less-developed spots.
Coverage on the water — including fast-boat crossings to Nusa Penida and the Gilis, and Komodo liveaboards — is patchy on all operators. Don't rely on mobile data for important communications during boat trips. The same applies on remote mountain roads in the north — expect intermittent service through the highland passes.
Most SIM purchases in Bali are straightforward — but a few common traps catch visitors out every year. Avoid them all with these seven tips.
Stick to operator stores, airport kiosks run by the operators themselves, or reputable eSIM providers. Avoid loose street vendors who can't show official operator branding.
Balinese law requires SIMs to be registered to your passport. Unregistered SIMs can be deactivated without notice mid-trip. If a seller doesn't ask for your passport, walk away.
Some sellers quote "unlimited" plans that turn out to be capped at low daily allowances. Ask exactly: how much high-speed data per day, how many days, and what happens after the cap.
Pop the SIM in, restart your phone, and confirm data works before you walk out. If it doesn't activate within 10 minutes, ask the seller to fix it on the spot — not via WhatsApp later.
A 30-day tourist plan should not cost more than $25. If a kiosk is quoting $40–$50 or more, you're being overcharged. Walk to the nearest official operator store instead.
Always carry the ejector tool, store your home SIM in its plastic holder, and put it somewhere you'll remember. Travelers regularly lose home SIMs swapped out in a hostel room.
Use the operator's app, an Indomaret or Alfamart, or any small shop displaying the operator's logo. Most top-ups (pulsa) take effect within seconds — don't wait until you're out of data on the islands or in a remote area.
