Network coverage in Indonesia

Indonesia's mobile coverage is strong in tourist hotspots and patchy once you leave them. Your Travelren Indonesia eSIM roams on Indosat Ooredoo Hutchison as the primary network with Smartfren as a fallback — note this is NOT Telkomsel, which dominates rural and remote-island reach in Indonesia. 5G is live in Jakarta, Surabaya, Bandung, Medan, Denpasar, and across Bali's tourist belt (Seminyak, Canggu, Ubud, Uluwatu, Nusa Dua) with typical speeds of 60 to 150 Mbps. 4G LTE is solid in all Java cities, across mainland Bali, and along the main Trans-Java toll road. Coverage is reliable on Lombok's tourist coast and the main Gili Trawangan strip but weakens fast on Gili Meno, Gili Air, Nusa Lembongan, Nusa Penida, the Komodo islands, and most of Sumatra, Kalimantan, Sulawesi interior, and Papua.

What works in Indonesia

✅ Works well

Grab and Gojek — both essential for Bali transport (motorbikes, cars, food)
Google Maps and Apple Maps for motorbike routing across Bali and Java
WhatsApp — the default messaging app in Indonesia for villas, drivers, and tour operators
GoFood, GrabFood, and ShopeeFood for delivery in Bali and major cities
Booking villas and activities via Booking.com, Agoda, and Klook
Streaming on 5G in Seminyak, Canggu, Jakarta, and Surabaya
QR-based payments via GoPay, OVO, and DANA at warungs and beach clubs in tourist areas
Tethering a laptop for remote work from Bali co-working cafes

⚠️ Watch out for

Gili Meno, Gili Air, Nusa Lembongan, Nusa Penida, and Komodo National Park have weak or intermittent signal — download offline Google Maps and translation packs before you go
Indosat does not have Telkomsel's rural reach — if you're heading to remote villages in Bali's north, the Sumatran interior, or Sulawesi off the main road, expect dead zones
Most warungs (small local restaurants), markets, and rural shops outside tourist areas are cash-only — bring rupiah even with strong data coverage
Indonesian banking and government apps (BCA mobile, BRImo, PeduliLindungi) require an Indonesian phone number — none are tourist essentials
Free DPS airport WiFi (@FreeWifiDPS) is unreliable during peak arrival hours — install your eSIM before flying

Arriving in Indonesia

Bali Ngurah Rai (DPS) — the airport every Bali traveller arrives at — offers free WiFi via the @FreeWifiDPS network in both the international and domestic terminals, but it slows to a crawl during peak arrival waves and may require email registration. Jakarta Soekarno-Hatta (CGK) and Surabaya Juanda (SUB) both have free terminal WiFi as well. Telkomsel and XL Axiata run physical SIM kiosks in the DPS arrivals hall — packs start around IDR 150,000 (roughly AUD$15) for 30 days, but Indonesia legally requires passport registration for any local SIM since 2018. An eSIM bought before you fly skips that entirely. Bali has no metro or tap-to-pay transit infrastructure — Grab and Gojek motorbikes (around IDR 15,000 for short hops) are the universal way to get around. Jakarta's MRT began rolling out EMV contactless tap-to-pay (Visa/Mastercard) at gates from late 2024; the integrated JakLingko card or app remains the most reliable option for TransJakarta BRT, MRT, and LRT in 2026. Cash is still king outside tourist hotspots; ATMs are everywhere. Beach clubs, villas, and Seminyak/Canggu restaurants accept Visa, Mastercard, and QR-based GoPay/OVO/DANA.

Installing your Indonesia eSIM

Install on your home WiFi

iPhone: Settings → Mobile Data → Add eSIM → scan the QR code from your email. Android: Settings → Connections → SIM Manager → Add eSIM. Takes about two minutes.

Land in Indonesia

Install your Indonesia eSIM at home on your own WiFi before you fly — it takes about two minutes. On iPhone: Settings → Mobile Data → Add eSIM, then scan the QR code from your email. On Android: Settings → Connections → SIM Manager → Add eSIM. Leave your home SIM as the primary line for calls and SMS. Switch the Indonesia eSIM on for data only when you land. Your home number stays active throughout the trip. If you forget to install before departure, the free DPS airport WiFi (@FreeWifiDPS) works for installation, but it slows badly during peak arrival waves — much better to arrive ready.

Keep your home SIM for calls

Leave your home SIM in. Set the Indonesia eSIM as your data line only. Your number stays active the whole trip.

Good to know

A few details before you buy.

Calls and SMS

Most plans are data only — use WhatsApp or FaceTime for free. Look for the phone chip plan if you need a local number.

Compatibility

Your phone must be eSIM compatible and network-unlocked. Check yours →

Refunds

If your eSIM doesn’t activate, we’ll refund you in full. No questions asked.

Common questions

Which carrier does Travelren use in Indonesia?

Your eSIM connects to Indosat Ooredoo Hutchison as the primary network with Smartfren as a fallback. Note this is not Telkomsel — the carrier with the deepest rural and remote-island reach in Indonesia. Indosat is strong across Bali tourist areas, all Java cities, and Lombok's tourist coast. Your phone selects the strongest signal automatically. No APN configuration or manual network switching is required.

Will my eSIM work across Bali?

Yes across the tourist belt. Denpasar, Seminyak, Canggu, Ubud, Uluwatu, Nusa Dua, Sanur, and Jimbaran all have strong Indosat 4G LTE with 5G in central areas. Coverage along the main road from DPS to Ubud is solid. Expect weaker signal in the far north (Lovina, Pemuteran), the central highlands around Mount Batur and Munduk, and inside dense rice-terrace valleys. Download offline Google Maps for any inland scooter day trip.

What about the Gili Islands and Nusa Lembongan/Penida?

Gili Trawangan has reliable 4G in the main strip and harbour. Gili Meno and Gili Air have intermittent signal — usable for messaging but slow for streaming or maps. Nusa Lembongan tourist areas (Mushroom Bay, Jungutbatu) have workable coverage; Nusa Penida is much patchier, with strong signal only near Toyapakeh harbour and the main road, and weak or no signal at Kelingking, Diamond Beach, and Atuh. Download offline maps before you cross.

Does Indonesia support eSIM?

Yes. Indosat Ooredoo Hutchison, Telkomsel, XL Axiata, and Smartfren all support eSIM. iPhones from the XS onwards, Google Pixel 3 and later, and most recent Samsung Galaxy models all work. Important exception: iPhones purchased in mainland China do not include eSIM hardware even if the model number looks identical. Use travelren.com/device-check to confirm your phone in 30 seconds.

Can I use my eSIM at Bali Ngurah Rai (DPS) airport?

Yes. DPS arrivals hall has reliable Indosat coverage throughout immigration, baggage claim, and the arrivals taxi pickup zone. Your eSIM activates the moment your phone connects to an Indonesian network — usually while taxiing to the gate. Most travellers are online before reaching immigration, which is critical because the free DPS WiFi (@FreeWifiDPS) slows to a crawl during peak arrival waves.

How much does roaming cost without a Travelren eSIM?

Telstra charges AUD$10 per day for Indonesia (Zone 2) under its International Day Pass with a 2 GB daily cap. AT&T's International Day Pass is USD$12 per day, capped at 10 days per bill cycle. EE's Travel Data Pass for Indonesia is around £6.27 per day (Indonesia is outside the EU zone — verify on EE's roaming-costs page before relying on it). Spark NZ's 14-day Roaming Pack is NZD$30. Travelren plans are typically cheaper on a per-day basis without the daily cap or fixed midnight cutover. Check my device →

Do I need to register my SIM with my passport in Indonesia?

Physical tourist SIMs bought from Telkomsel, Indosat, or XL kiosks at DPS, CGK, and other airports require passport registration under Indonesian regulation in force since 2018 — staff scan your passport and link it to the SIM before activation. An eSIM purchased from Travelren skips that step entirely. You install it before you leave home, activate it on arrival, and no passport registration is required.

How do I get around Bali, and do I need data for Grab and Gojek?

Bali has no metro or tap-to-pay transit. Grab and Gojek motorbike (ojek) and car rides are the universal way to move around — short hops are typically IDR 15,000 to 30,000 (under AUD$3). Both apps require a working data connection to book, track the driver, and pay via GoPay or OVO. Renting a scooter is also common, in which case Google Maps over your eSIM is essential for navigation through Bali's unsigned back roads.
