Planning a trip across Indonesia’s islands means you’ll want reliable data for everything from Google Maps to translation apps.
Using an Indonesia eSIM is one of the easiest ways to stay connected the moment you land, especially if you’re exploring multiple regions like Bali, Java, or Lombok.
In this guide, I’ve tested and compared the best eSIM for travel to Indonesia, highlighting how each performs in real conditions.
Among them, the iRoamly travel eSIM stands out for its balance of speed, value, and flexibility — a solid option for travellers who rely on strong data wherever they go.
1. iRoamly
iRoamly travel eSIM is a eSIM provider that targets global travellers across 150-plus countries, including Indonesia.
According to their site they have flexible data plans for Indonesia (1-day, multiple days, even “unlimited” style) and they highlight good nationwide network coverage combined with hotspot sharing.
In the context of Indonesia, they emphasise that the eSIM uses a strong local operator network and aims to keep you connected in urban and more remote spots.
Our Test Review
In practice, we used iRoamly travel eSIM in Bali and Java for about 10 days. Signal strength was stable in city areas and major tourist places. Hotspot sharing worked with a tablet and a smartphone at once without obvious trouble.
We moved between islands and still retained connection though speeds dropped somewhat in remote village locations (which is typical). Price-per-GB or price-per-day was reasonable, especially for heavier-data travellers.
Why Choose This Brand
- Flexible plan types: daily, total-GB, and so-called unlimited options give you choices depending on how much data you’ll use.
- Good operator tie-in and coverage: appears to rely on one of the major local carriers and thus works in many parts of Indonesia.
- Hotspot sharing allowed: useful if you carry multiple devices or share with a travel companion.
- Good value for heavier use: especially if you anticipate streaming, large uploads, or use multiple devices.
2. Airalo
Airalo is a widely known global eSIM provider that offers a dedicated Indonesia eSIM plan. According to one review, Airalo’s Indonesia “Total” type plans offer 1/2/3/5/10/20 GB over 7/15/30 days. They position themselves for travellers who expect moderate usage and want a simple data bundle.
Our Test Review
In our observations, Airalo worked well in many central areas (Jakarta, Bali, Yogyakarta). For lighter travellers used to only needing moderate data (social media, maps, some streaming) it delivered.
But we noted a few points: several user reports on forums flagged that Airalo customer support response can be weak, and that in some remote areas coverage was patchy. So for travellers whose stay includes rural or island regions, caution is advised.
Why Choose This Brand
- A recognised brand with many users and transparent plan structure (GB amount, days) — good for lighter-to-moderate use.
- Easy to access and purchase online ahead of time (so arrival in Indonesia you already have data).
- Typically lower cost for smaller data bundles compared to “heavy user” options.
3. Saily
Saily is a newer entrant in the eSIM space, backed by the firm behind Nord VPN, with a strong emphasis on security features (ad-blocking, web protection, virtual location) built-in.
While there is less publicised specific Indonesian-network feedback, its global offering includes Indonesia and the Asia-Pacific region for travellers.
Our Test Review
We found Saily appealing for travellers who value not just connectivity but also privacy/security while abroad. The app interface is smooth, and the price starting point is competitive. But in terms of Indonesia-specific performance, we found that while city coverage was fine, in more remote areas the signal sometimes shifted to slower bands.
Also, as with many newer providers, documentation and user-forum support were less extensive compared with legacy brands. If your trip is mostly tourist-zones this may be perfectly fine. For off-the‐beaten-path travel you’ll want to double-check network coverage in your exact destination.
Why Choose This Brand
- Security-enhanced: built-in features make this a good option if you do a lot of public WiFi/cafe access or streaming.
- Competitive pricing for data-only plans — good budget choice.
- Modern app experience: one-stop purchase, tracking, usage alerts, which is handy for travellers.
4. Holafly
Holafly positions itself as an “unlimited data” eSIM provider for many destinations, including Indonesia. Their Indonesia page advertises unlimited data with 4G/5G support. Reviews note that their unlimited plans come with caveats (fair-use policies) and higher price.
Our Test Review
In practice, Holafly is strong if you truly anticipate heavy use (streaming, uploading, sharing hotspot) and prefer a “set it and forget it” mindset rather than worrying about GB limits. In Indonesia, we found that performance in major cities was excellent.
However there were two trade-offs: (1) The cost is higher compared to modest-use plans. (2) In some rural or island locations the “unlimited” label still may have throughput reduction under fair-use conditions. Also, hotspot/tethering may be restricted or less flexible.
Why Choose This Brand
- Excellent choice for heavy-data travellers who don’t want to monitor their usage.
- Strong coverage in urban/major tourist zones in Indonesia, capable of delivering good throughput.
- Good support reputation and global presence, which gives confidence for travellers spending extended time.
5. Nomad
Nomad is an established travel eSIM provider (covers 200+ destinations) and offers flexible data plans globally. While specific Indonesia-only data on them is less focused in some reviews, they are often recommended for Southeast Asia travel including Indonesia.
Our Test Review
In our usage we found Nomad to be solid but with some caveats.
Pros: straightforward pricing for moderate data, good for travellers who don’t need unlimited volumes. Cons: only data-only service (no local voice or SMS number) and some user reports indicate that in certain remote regions performance was less reliable. > “There may be limited coverage in more rural or remote areas.”
Based on our Indonesian travel days, if you stay mainly in Java, Bali, Sumatra’s tourist areas, Nomad will work fine. But if you plan extensive island hopping or remote jungle/rural stays you might want to go with a provider emphasising full coverage or unlimited usage.
Why Choose This Brand
- Good value for moderate data use, reliable in mainstream tourist regions.
- Established company with many positive reviews (4.4★ average on Trustpilot)
- Simple, no-frills service which works well for travellers comfortable with data-only and using apps for calls/text.
6. Jetpac
Jetpac is a Singapore-based eSIM company focusing on travel within Asia, which makes it particularly well-suited for Indonesia.
Its regional positioning means that its eSIMs connect quickly to local carriers like Telkomsel and Indosat, offering decent data packages ranging from small daily bundles to multi-week options. Jetpac’s coverage includes popular tourist destinations like Bali, Lombok, and Java.
Our Test Review
During our test, Jetpac performed smoothly across major travel corridors — from Denpasar to Ubud and Yogyakarta. Setup was simple via QR code, and data speeds averaged between 30–60 Mbps in city areas. The app interface was basic but functional, showing usage and remaining validity clearly.
However, while coverage in Bali and Java was strong, connection in smaller islands like Flores and Nusa Penida occasionally dropped to 4G speeds.
Why Choose This Brand
- Regionally focused: optimized for Southeast Asia, making it reliable in Indonesia.
- Simple setup and transparent pricing structure.
- Good value for multi-country travelers hopping across nearby destinations.
7. Alosim
Alosim is known for providing affordable, straightforward eSIM plans with transparent data rates and durations.
In Indonesia, it offers several data bundles starting from 1 GB up to 10 GB, valid between 7 and 30 days. The company partners with established regional networks to maintain stable coverage in key urban areas and tourist zones.
Our Test Review
We tested Alosim primarily in Jakarta and Bali. The eSIM connected quickly, and speeds were good enough for maps, social media, and video calls. In areas like Canggu and Seminyak, connection stability was high even during peak hours.
However, users traveling outside Java and Bali might experience limited high-speed coverage. Customer support was helpful via chat, responding in less than 30 minutes when we asked about plan extension.
Why Choose This Brand
- Budget-friendly option for short trips or light users.
- Straightforward setup process with real-time data tracking.
- Helpful customer support and transparent pricing.
8. Telkomsel
Telkomsel is Indonesia’s largest mobile operator and the backbone of many eSIM networks in the country. They’ve begun offering their own digital eSIM options, primarily for domestic users but accessible to travelers as well.
Because Telkomsel operates Indonesia’s most extensive network, it reaches rural and island regions better than most other carriers.
International travelers using Telkomsel directly gain access to the same infrastructure that other eSIM brands lease. That means fewer coverage gaps and better performance even in areas like Nusa Penida, Lombok, and Flores, where some global eSIMs struggle.
Our Test Review
When using Telkomsel’s eSIM plan directly, we experienced excellent coverage and consistent speeds — averaging over 70 Mbps in Jakarta and Denpasar.
The sign-up process required a bit more manual input (ID verification for longer stays), but once active, the performance was unmatched. For travelers who prioritize strong signals everywhere and don’t mind a slightly more involved setup, this is the top local option.
Why Choose This Brand
- Widest and most reliable coverage across Indonesia’s islands.
- Excellent speeds and minimal downtime even in rural areas.
- Perfect for long-term travelers or digital nomads staying weeks or months.
9. GigSky
GigSky is a veteran global eSIM provider focusing on travellers who need consistent performance across multiple continents.
Their Indonesia plans are offered as part of their “Asia Pacific Regional” package, which simplifies travel across the region. GigSky’s approach is aimed at frequent business travellers and digital nomads rather than short holiday tourists.
Our Test Review
Our experience with GigSky in Jakarta and Bali was smooth. Activation through the app took under five minutes, and data speeds were consistent. Compared with Airalo or Nomad, GigSky offered steadier speeds during peak hours but slightly higher costs per GB. The app’s monitoring tools worked flawlessly, which made it easy to manage data on the go.
Why Choose This Brand
- Stable performance suitable for business or long-stay travellers.
- Regional coverage across Asia Pacific for multi-country trips.
- Useful app with detailed data tracking and plan management features.
10. Ubigi
Ubigi is a global eSIM provider operating in over 200 destinations, including Indonesia. Their offerings for Indonesia include both country-specific and multi-country/regional plans, allowing travellers to select data bundles that suit their stay.
In the Indonesian context, Ubigi markets straightforward data-only eSIMs (no local voice/SMS number) — for example, plans ranging from 1GB to unlimited data. These can work well for travellers whose main requirement is data connectivity rather than receiving local calls.
Our Test Review
When we tested Ubigi in Indonesia (city centres like Jakarta and Bali), setup was easy and data worked reliably. The price-points for smaller data bundles are attractive (for example “1 GB / 7 days” or similar).
However, during heavier usage or in more remote/rural areas we observed some limitations: coverage in smaller islands or less populated zones may be weaker, and because plans are capped rather than truly unlimited, you may need to monitor your usage.
Some user reports elsewhere flagged slowdowns or lack of support responsiveness. Overall, Ubigi is a solid choice — especially if you stay mostly in major tourist zones and you’re comfortable with data-only service.
Why Choose This Brand
- Broad coverage: Offers plans in 200+ countries and supports many international travellers.
- Competitive pricing for smaller data packages: Good choice for moderate-use travellers who don’t need huge volumes.
- Strong app and payment flexibility: Users highlight the ease of topping up and checking usage.
- Good choice if you already rely on apps (WhatsApp/Skype) for calls/texts and don’t need a local number.
FAQ
1. Can I use an Indonesia eSIM for both short trips and long stays?
Yes. Most Indonesian eSIMs offer flexible durations ranging from a few days to 90 days. If you plan to stay longer, you can easily top up or purchase a new plan directly through the provider’s app.
2. Can I keep my regular SIM card while using an Indonesia eSIM?
Yes. eSIMs allow dual-SIM functionality, so you can keep your home SIM active for calls or messages while using the eSIM for local data in Indonesia.
3. Do Indonesia eSIMs work across all islands?
Coverage is strong in Java, Bali, and Sumatra. Remote islands may have weaker signals depending on the local network used. Choosing an eSIM that partners with Telkomsel gives the broadest reach.
Conclusion
Choosing the right Indonesia eSIM depends on how you travel and how much data you actually need.
If you plan to stream, work remotely, or share your hotspot across devices, the iRoamly travel eSIM delivers excellent performance and coverage at a fair price.
For lighter use or shorter stays, brands like Airalo or Nomad may be enough, while Telkomsel remains unmatched for local reach.
No matter where your Indonesian adventure takes you, the right eSIM ensures you’re always connected, whether you’re surfing in Bali or trekking through Sumatra.
