eSIM for Indonesia: What Actually Works in 2026
Jump to all plansFor Indonesia in 2026, the strongest combination of price and network is Travelsim Asia at $10.99 for 5 GB / 30 days on Telkomsel and XL — the two networks with the most reliable nationwide coverage from Sumatra to Papua. Holafly matches that network combination at flat per-day unlimited pricing from $11.70, but does not publish its daily Fair Usage Policy threshold (widely assumed ~2–3 GB/day, varies by destination). Tethering is separately capped at 1 GB per day — Holafly is the only provider here that limits hotspot separately. For Bali-specific travelers, the Bali eSIM guide covers tested results and Bali-tailored recommendations. For the rest of Indonesia, the same six providers compete — Telkomsel access is the deciding factor outside of Java.
What changed (June 2026): Airalo cut its 5 GB Indonesia plan from $14.00 to $13.50 (10 GB to $21, unlimited 30-day to $69); Ubigi’s unlimited dropped to $24 (7-day) / $59 (30-day). Saily’s unlimited carries a disclosed 5 GB/day fair-usage threshold. Travelsim Asia and Holafly pricing held steady.
What Actually Matters for Indonesia
1. Telkomsel access is the deciding factor. Indonesia is an archipelago of 17,500+ islands. Telkomsel is the only carrier with consistent coverage across Java, Sumatra, Sulawesi, Bali, Lombok, Flores, Komodo, and the eastern islands. Outside Jakarta and Surabaya, providers without Telkomsel access feel noticeably weaker — especially in Yogyakarta’s outskirts, Sumatra’s interior, and remote diving destinations.
2. Honest “unlimited” claims. Most Indonesia “unlimited” eSIMs include a daily Fair Usage Policy. Holafly does not publish its FUP threshold anywhere on their website — community reports and Holafly’s own support chat suggest ~2–3 GB per day before throttling, but the exact number is unstated and varies by destination. Post-throttle speed is reported at 256–1024 Kbps. This is the single most important fact to know before buying an “unlimited” Indonesia plan.
3. Tethering is a separate daily cap. Holafly’s tethering (hotspot to laptop/tablet) on “unlimited” plans is capped at 1 GB per day in Indonesia — distinct from the FUP throttle above, and the only separate hotspot cap among these providers (some third-party reviews still cite ~500 MB). Indonesia’s café WiFi is reliable in Bali and Jakarta CBD but spotty in Yogyakarta, Lombok, and Sumatra, so laptop-tethering travelers should pick a fixed-data provider where tethering runs at full speed and counts against your overall allowance: Travelsim Asia, Airalo, Saily, Nomad, or Ubigi.
4. Multi-island itineraries matter. A Bali-Lombok-Komodo trip stays within Indonesia but crosses time zones and connectivity regions. Pick a provider with country-wide coverage, not just urban-Java coverage — Telkomsel-based plans are the safest pick.
5. Price per usable GB. Indonesia is moderately priced for travel eSIMs — cheaper than Japan, more expensive than Thailand. The 5 GB / 30-day tier ranges from $10.99 (Travelsim Asia) to $13.99 (Saily). Compare on the plan size you’ll actually use — not the headline cap.

What “Unlimited” Actually Means Here
No “unlimited” Indonesia eSIM is truly uncapped — every one slows to a crawl after a daily high-speed allowance. What separates them is whether that allowance is published, how large it is, and how slow the throttle gets:
- Saily — 5 GB/day, then 1 Mbps. The most generous daily cap of the group, and the threshold is published in its terms.
- Airalo — 3 GB/day, then 1 Mbps.
- Nomad — 2 GB/day, then 512 Kbps. The tightest cap and the slowest fallback here.
- Ubigi — sold as high-cap buckets (20 GB on the 7-day plan up to 60 GB on the 30-day), then 2 Mbps — the most usable post-throttle speed.
- Holafly — no daily figure published at all. Community reports and Holafly’s own support chat suggest ~2–3 GB per day before speeds drop to 256–1024 Kbps, but the number is never stated at checkout and varies by destination.
Holafly is also the only provider that caps tethering separately. Its standard “unlimited” eSIM limits hotspot to 1 GB per day in Indonesia even while phone data stays unlimited — that is the figure on Holafly’s current Indonesia page, though some third-party reviews still cite 500 MB. On Travelsim Asia, Airalo, Saily, Nomad, and Ubigi, tethering simply draws from your allowance at full speed with no separate cap. Holafly’s separate Holafly Plans subscription ($64.90/month) lifts the hotspot cap entirely.
For predictability, choose a fixed plan sized to your trip; for genuine unlimited, Saily is the most laptop-friendly and the most transparent. Holafly’s undisclosed daily limits can mean 256 Kbps for the last hours of every day — slower than dial-up.
When Unlimited Pays Off
The break-even math, based on May 2026 pricing:
Rule of thumb: unlimited starts paying off above ~2 GB per day — but the Holafly FUP threshold for Indonesia is reportedly in that same ~2–3 GB range, so heavy users may hit the throttle before getting their money’s worth. The “unlimited” framing falls apart precisely when you’d actually need unlimited.
Realistic usage in Indonesia is 2–3 GB per day for most travelers — and that’s with patchy WiFi in some regions (Lombok, Sumatra, Komodo). In Bali and Jakarta CBD, WiFi is widely available and usage trends lower. In remote diving destinations or trekking regions, mobile data is your only option and usage scales with how much navigation, weather-checking, and messaging you do.
For a typical 7-day Indonesia trip with WiFi access in cities, 5–10 GB of fixed data is plenty. For multi-island itineraries with limited WiFi, plan for 10–20 GB.
Which eSIM for Your Trip
Networks and Coverage Across Indonesia
Indonesia has five main mobile networks. Coverage varies sharply by region:
- Telkomsel — the only carrier with consistent nationwide coverage. Best signal across Java, Sumatra, Sulawesi, Bali, Lombok, Flores, Komodo, Papua. Default safe pick. Used by Travelsim Asia, Nomad, and Holafly.
- XL Axiata — strong in Java (Jakarta, Bandung, Yogyakarta, Surabaya) and southern Bali. Decent in Lombok and West Sumatra. Weak in eastern Indonesia. Used by Travelsim Asia and Holafly. Recently merged with Smartfren to form XLSmart.
- Indosat Ooredoo Hutchison (IOH) — Java-focused. Decent in Jakarta, Surabaya, Bandung. Thinner in Bali outskirts and weaker outside Java. Used by Airalo, Ubigi.
- Smartfren — urban 4G/5G focus, very limited outside Java and Bali. Now part of XLSmart but Nomad still routes via Smartfren on some plans.
For coverage outside Java and Bali, Telkomsel access is the most important factor. The Travelsim Asia / Nomad / Holafly trio are the only providers with Telkomsel access.
Regional coverage notes
- Bali — all five networks work in Canggu/Seminyak/Denpasar. Telkomsel + XL are the safe picks for Uluwatu, Ubud, and northern Bali. See the Bali eSIM guide for tested details.
- Java (Jakarta, Yogyakarta, Surabaya, Bandung) — all networks work well in urban areas. Telkomsel still has the edge in rural Java and around Borobudur.
- Lombok and Gili Islands — Telkomsel is the strongest. XL works in Mataram and Senggigi. Other carriers thin.
- Komodo / Flores — Telkomsel only, realistically. Most other networks have spotty or no coverage outside Labuan Bajo.
- Sumatra — Telkomsel dominates rural Sumatra; XL covers major cities (Medan, Padang, Palembang).
- Sulawesi and eastern Indonesia — Telkomsel only.
Free WiFi in Indonesia
WiFi is widely available in Bali, Jakarta CBD, and most tourist areas. Reliability drops sharply outside main hubs — expect to use mobile data heavily in Komodo, eastern Sumatra, and rural Lombok. Plan data needs accordingly.
How Much Data Do You Actually Need?
Most Indonesia travelers fall in the middle row — 1.5–3 GB per day across a multi-city or multi-island itinerary. A 10–20 GB plan covers a 1–2 week trip comfortably.

Nomad Nomad Nomad Nomad Nomad Nomad Frequently Asked Questions
What’s the best eSIM for Indonesia in 2026?
Travelsim Asia at $10.99 for 5 GB / 30 days is the strongest combination of price and network — Telkomsel + XL coverage, fixed full-speed data, no app required. For Bali-specific recommendations and tested results, see the Bali eSIM guide.
Is Holafly really unlimited in Indonesia?
No. Holafly’s Indonesia “unlimited” plans throttle after a daily Fair Usage Policy threshold. The exact daily limit is not published anywhere on Holafly’s website — community reports indicate roughly 2–3 GB per day before throttling, but the number varies by destination and is never stated at checkout. Tethering is separately capped at 1 GB per day. For predictable speed, a fixed 5–10 GB plan from Travelsim Asia or Nomad outperforms Holafly’s undisclosed unlimited.
Which carrier has the best Indonesia coverage?
Telkomsel — the only carrier with consistent coverage across Java, Sumatra, Sulawesi, Bali, Lombok, Flores, Komodo, and eastern Indonesia. For trips outside main urban areas, Telkomsel access is the most important factor when choosing an eSIM. Travelsim Asia, Nomad, and Holafly all connect to Telkomsel.
Will my eSIM work in Komodo, Flores, and eastern Indonesia?
Telkomsel is realistically the only carrier with workable coverage in Komodo, Flores, eastern Sulawesi, and Papua. Use a Telkomsel-connected provider (Travelsim Asia, Nomad, or Holafly) for these destinations. Other networks are spotty or absent outside Labuan Bajo and major regional capitals.
Do I need to register my eSIM with my passport?
No. International eSIM providers bypass Indonesia’s local SIM registration requirement. This is one of the practical advantages over buying a local Telkomsel or XL SIM at the airport, which requires passport scanning and queueing.
Should I buy a local Telkomsel SIM at the airport instead?
A local Telkomsel tourist SIM (~50,000 IDR or ~$3 starter pack) is cheaper per GB than any eSIM but requires passport registration and queueing. For trips under 14 days, eSIM convenience wins. For 30+ day stays, a local SIM is meaningfully cheaper. The eSIM advantage is biggest for short trips and multi-city itineraries where you want immediate connectivity on every landing.
Can I install the eSIM before flying to Indonesia?
Yes. eSIMs install before departure and activate on first connection to an Indonesian carrier. Install at home, fly with WiFi-only, and the plan starts when you land. This is the cleanest way to land at Jakarta (CGK), Bali (DPS), or Yogyakarta (YIA) and skip the airport SIM counter entirely.
What about Bali specifically?
For Bali — tested results, Bali-specific network notes, and recommendations tailored to Canggu, Ubud, Uluwatu, and rural Bali — see the dedicated Bali eSIM guide. The provider comparison is similar but the framing is Bali-first.
