Connectivity Across Indonesia

Jakarta: As the capital, Jakarta offers excellent and reliable 4G/LTE and growing 5G coverage throughout its central business districts like SCBD and Kuningan. Major malls and modern buildings have strong indoor signals. The Jakarta MRT system provides consistent connectivity on platforms and within most of the underground tunnels, though you may experience brief drops between some stations.

Bali (Denpasar & South): The main tourist hubs of Kuta, Seminyak, Canggu, and Nusa Dua have very strong and fast 4G/LTE coverage. The signal remains good in central Ubud but can become less reliable in more remote villas, mountainous northern regions, or on smaller surrounding islands like Nusa Penida. Indoor coverage in thick-walled villas can sometimes be weaker than in open-air resorts.

Surabaya: Indonesia's second-largest city boasts comprehensive 4G/LTE coverage across its urban and commercial areas. Connectivity is generally strong in major shopping centers like Tunjungan Plaza and business districts. As there is no extensive underground transit system, signal consistency is high outdoors, though coverage inside older, densely-packed residential buildings or large industrial warehouses can vary.

Yogyakarta: Coverage in the city center, including the bustling Malioboro Street and around the Kraton palace, is very reliable. The network performs well when traveling to major nearby temples like Prambanan and Borobudur. However, the signal can become patchy in rural areas outside the main tourist corridors. Indoor signals in traditional guesthouses or older buildings might not be as strong as in modern hotels.

Connectivity Between Cities

Trans-Java Toll Road: Major carriers provide generally reliable 4G coverage along this core expressway network connecting Java's largest cities. Expect stable signal in and around Jakarta, Bandung, Semarang, and Surabaya, but be prepared for intermittent signal drops in the more rural agricultural sections between these metropolitan areas.

Intercity trains (KAI): Coverage on standard Kereta Api Indonesia routes is inconsistent. While you will have signal leaving and approaching major city stations, the connection frequently drops in rural areas, valleys, and older tunnels. The Jakarta-Bandung High-Speed Railway ("Whoosh") offers more consistent connectivity due to modern infrastructure, though brief drops in its longer tunnels are possible.

Mountainous regions: Signal is highly unreliable when traveling through highland areas. The popular Puncak Pass route between Bogor and Cianjur is known for very patchy service. Similarly, crossing the Barisan Mountains in Sumatra or the central highlands of Flores and West Papua will result in extended periods without any cellular connection.

Inter-island ferries: While near major port cities like Merak, Bakauheni, or Padang Bai, your signal will be strong. However, on longer ferry journeys between islands, such as across the Sunda Strait or Lombok Strait, you will lose the terrestrial network signal once you are several kilometers from shore, only regaining it as you approach your destination.

Eastern Indonesia and remote areas: Connectivity is sparse outside of Java and Bali. In regions like Kalimantan (Borneo), Sulawesi, Nusa Tenggara, and Papua, reliable signal is often limited to provincial capitals and major towns. Overland travel between cities or into the interior will involve long stretches with no service at all.

What our happy customers say about bcengi eSIM

I loved the per-country pricing model. I only paid for the countries I visited, and it was way cheaper than other eSIM providers. No hidden fees — just clear and simple.

No more buying a new SIM card every time I land somewhere. I traveled through 5 countries in two weeks, and the eSIM worked flawlessly everywhere. Total game changer!

The auto top-up feature is a lifesaver. I never have to check my balance — internet just works. And when I’m not traveling, I don’t pay. It’s fair and super convenient.

Frequently Asked Questions

How much does eSIM data cost in Indonesia?

eSIM data in Indonesia is priced at $1.81 per GB when utilizing the Tri and Indosat networks. No data bundles or expiration dates apply; you are billed solely for the data consumed, on a per-MB basis.

Do I need to remove my physical SIM to use a travel eSIM?

No, there is no need to remove it. Your travel eSIM operates concurrently with your current physical SIM. This allows you to retain your domestic SIM for calls and text messages while leveraging the eSIM for data services within Indonesia.

Can I use a travel eSIM on my iPhone or Android?

Certainly, provided your device is eSIM-compatible. Supported models include iPhone XS and subsequent generations, Google Pixel 3 and newer versions, and Samsung Galaxy S20 and later releases. For verification of your particular model, please consult the compatibility list.

Does eSIM work everywhere in Indonesia?

No, it does not. While network coverage is robust across Java and Bali, it shows considerable variation throughout the rest of the archipelago. Remote islands such as the Gilis, Komodo, Nusa Penida, and Raja Ampat often experience minimal or no signal in numerous localities. It is advisable to download offline maps prior to departing areas with reliable connectivity.

How much data do I need for a week in Indonesia?

For a trip lasting one week, the majority of travelers typically require 2-5 GB of data. A week spent primarily in Bali usually consumes an average of 300-500 MB per day; however, time spent on boats or visiting secluded temples substantially reduces this daily average.

Does eSIM work on the Gili Islands?

Gili Trawangan offers basic 4G service, although it may suffer from congestion. Gili Air experiences very limited signal strength, and Gili Meno possesses the weakest connectivity. Across all three Gili Islands, anticipate slower speeds and inconsistent network access. Ensure you download maps and other offline materials prior to boarding the fast boat from Bali or Lombok.

Will I have signal in Ubud?

Yes, signal is available. Ubud benefits from reliable 4G coverage across its main town area, the Monkey Forest vicinity, and the popular rice terrace viewpoints. While mobile service in the adjacent rice fields (such as Tegalalang and Jatiluwih) is functional, it is not as robust as within the town itself. Additionally, many cafes and eateries in Ubud provide WiFi access.

Does eSIM work on boats to Komodo?

Cellular signal is very scarce on both liveaboard and day excursion boats journeying to Komodo National Park. While the town of Labuan Bajo offers network coverage, the islands themselves- specifically Komodo island, Rinca, and the adjacent marine areas- possess negligible to no mobile reception. This region represents one of the truly disconnected segments of an Indonesian itinerary.

Do I need Gojek in Indonesia?

For those spending time in Bali or Jakarta, the Gojek application proves exceptionally valuable. It facilitates services such as ride-hailing, food delivery, and mobile payments via GoPay. Grab serves as its primary competitor. Both applications necessitate a continuous data connection to function. Conversely, in more isolated regions and outlying islands, these services are often inaccessible or simply not feasible.

Can I use the same eSIM in Malaysia and Singapore?

Yes, this is possible. Bcengi TravelPass functions across numerous nations. Your remaining data balance seamlessly transfers between Indonesia, Malaysia, Singapore, Thailand, and other applicable destinations. Note that the cost per-GB may vary by country- please refer to the pricing page for up-to-date rates.
