Best SIM and eSIM for Indonesia: data plans, Wi-Fi and phone tips

For most trips of a week or less, an eSIM installed before you fly is the best option: it activates on landing and avoids the airport queue. Buy a local Telkomsel tourist SIM only if you stay longer than about two weeks or need the best rural coverage. Foreign phones staying over 90 days must be IMEI-registered (check).

Quick answer

If you land in Bali or Jakarta and want data within minutes, an eSIM is the simplest path: buy and install it at home, then switch it on when the plane lands. No shop, no queue, no passport copy.

If you are staying three weeks or more, or you plan to travel through Sumatra, Sulawesi, Kalimantan or Papua, a local Telkomsel SIM is worth the extra stop. Telkomsel has the best rural coverage in the country, and a local number makes it easier to receive calls from drivers, guides and homestays.

Quick answer
Trip type	Best pick	Why
1–7 days, Bali or Jakarta	Travel eSIM	Instant activation, no airport queue
1–4 weeks, mixed islands	Local Telkomsel SIM	Best rural coverage, local number
90+ days	Local SIM plus IMEI registration	Foreign phones must be registered (check)
Business or remote work	eSIM plus hotel Wi-Fi	Backup connection for calls and uploads

SIM options by passport and month

Prices below are 2026 estimates for a tourist data plan. They move with promotions, so treat them as a band, not a quote. The passport column matters less than the length of stay: Indonesia does not restrict tourist SIM sales by nationality, but registration rules and IMEI rules apply to the phone, not the person.

Passport / stay	Recommended option	Typical cost (2026 estimate)	Notes
US, UK, EU, AU, CA — under 30 days	Travel eSIM	USD 5–25	Buy before departure; check your phone supports eSIM

Costs are 2026 estimates; confirm current prices and registration rules before you buy.

Step by step

Before you fly: check that your phone is unlocked and supports eSIM. Most recent iPhones, Samsung Galaxy and Google Pixel models do; many older or carrier-locked handsets do not. Buy the eSIM from a provider that lists Indonesia, install it at home while you still have reliable Wi-Fi, and leave it switched off until landing.

On arrival: turn on the eSIM and enable data roaming for that line only. If you prefer a local SIM, buy it at the airport or at an official Telkomsel, XL or Indosat shop in town. Airport counters are convenient but usually cost more than city shops. Bring your passport; registration is standard.

Set-up: keep your home SIM active for bank codes and two-factor messages, and set the Indonesian line as the default for mobile data. Download Grab or Gojek and Google Maps offline for the areas you will visit. Pickup points for ride-hailing apps may be limited at airports and some tourist areas, so allow extra time.

If you stay over 90 days: register your phone's IMEI or it will lose local network access. This is a separate process from buying a SIM, so check the current rules before you arrive.

Notes

Coverage is strong in Bali, Java and the main tourist areas of Lombok and Sulawesi. It thins out on the outer islands, in national parks and on long boat crossings. Download offline maps and save your accommodation address in Indonesian before you leave the city.

Wi-Fi is easy to find in hotels, cafés, co-working spaces and malls in Bali and Java, and it is usually fast enough for messaging and maps. It is less reliable on the Gilis, in Flores and in Papua, so do not depend on it for calls.

Public Wi-Fi is not secure for banking. Use your mobile data or a VPN for anything sensitive. If you rely on calls, check whether your eSIM plan includes a local number or data only; many travel eSIMs are data-only.

Electricity is 230 V, 50 Hz, with round two-pin plugs (Type C and F). Bring an adapter. Power cuts are rare in tourist areas but can happen on smaller islands.
