Whether you're heading to the beaches and rice terraces of Bali, the temples of Java, the Komodo dragons, or the coral reefs of Raja Ampat, this comparison reviews the 6 best eSIMs for Indonesia and Bali in 2026: price per GB, 4G/5G network, and, most importantly, which ones actually have coverage beyond Bali, across the archipelago's 17,000 islands.
Access to the Telkomsel network, the only one that properly covers remote islands, eSIM installed in two minutes via an easy-to-use app, 24/7 human customer support, and the lowest price per GB in the comparison. The five alternatives below remain valid depending on your usage.
We ranked each eSIM based on six criteria, weighted specifically for Indonesia. The decisive local factor is coverage across the archipelago: the country has over 17,000 islands, and among the four major operators (Telkomsel, Indosat IM3, XL Axiata, and Smartfren), only Telkomsel provides reliable signal outside of Bali and Java. As for 5G, it's currently limited to Jakarta and Bali. Price per GB and network stability are the next most important factors, as the connection is excellent in tourist areas but more variable on remote islands and out at sea.

voilà eSIM comes out on top in this comparison. The eSIM provides access to the Telkomsel network, by far the most extensive in the country, as well as to Indosat, XL Axiata, and Smartfren. The result: whether you are in the rice fields of Ubud, on a ferry to the Gili Islands, or in the middle of Komodo National Park, you stay connected. You enjoy excellent value for money (the lowest price per GB in the comparison, with no commitment or hidden fees), an eSIM that is easy to install via an easy-to-use app, and human customer support, available 24/7.
Coverage
voilà eSIM provides access to Telkomsel, the most extensive of the four major Indonesian networks, but also to Indosat, XL Axiata, and Smartfren, with 4G everywhere and 5G in Jakarta and Bali. You will have signal from the moment you arrive at Ngurah Rai Airport in Denpasar, across the entire island of Bali (Canggu, Ubud, Seminyak, Uluwatu, Sanur, Nusa Dua), in Jakarta and Yogyakarta, but also on Lombok, in Flores, in Komodo National Park, on Sulawesi, and even on the beaches of Raja Ampat. The connection remains solid where plans relying solely on secondary networks struggle as soon as you leave Bali.
Pricing
voilà eSIM offers excellent value for money: the price drops to $0.70 per GB on the 50 GB plan, the lowest price per GB in the comparison. Offers range from 1 to 50 GB, valid for 7 to 30 days depending on the volume (30 days for 5 GB and up). You pay for the data, nothing else: no hidden extra costs, and hotspotting is included.
Activation
The eSIM is easy to install: you purchase and activate it in two minutes from the voilà eSIM app, which is easy to use daily to track your consumption. You scan a QR code before departure, without handling a physical card. The line activates as soon as you land in Indonesia, and you keep your usual number for calls and SMS.
Support
voilà eSIM's human customer support responds 24/7, both before and during your trip. Your applications work normally: Gojek and Grab for getting around, WhatsApp and FaceTime calls, Google Maps and Google Translate, diving and ferry apps, Instagram stories, and Netflix streaming in the evening all run without interruption. You stay reachable and connected from the first to the last day.
Who is it for?
voilà eSIM is suitable for all profiles: a relaxing stay in Bali, a road trip in Java, diving in Komodo or Raja Ampat, or island hopping between Lombok and the Gilis. It offers the best value for money for Indonesia in 2026, with reliable coverage even on remote islands.
8.5/10Nomad works on a pay-as-you-go data basis, without a subscription, starting from $0.82 per GB in Indonesia on its 50 GB plan valid for 45 days, the closest rate to voilà eSIM. The eSIM also relies on the Telkomsel network, the application is clear, and the purchase is fast. Smaller plans are significantly more expensive per GB and support remains in English. Read our review of Nomad.
8.0/10Ubigi offers rechargeable data plans in Indonesia, from 1 to 25 GB, as well as unlimited plans, starting from $1.12 per GB on the 25 GB plan. You add data directly in the app, without having to buy a full new plan. The price per GB remains higher than voilà eSIM, Nomad, and Airalo, support is limited to English, and the interface seems dated compared to newer players. Read our review of Ubigi.
7.9/10Saily is the eSIM from NordSecurity, the publisher of NordVPN. Expect to pay starting from $1.80 per GB in Indonesia (20 GB plan), the highest price per GB among the data plans in this comparison. Saily also offers unlimited plans from 5 to 30 days. The offer focuses on security, with a built-in ad and tracker blocker. Support remains in English. See our review of Saily.
7.7/10Airalo is the most well-known eSIM brand, present in over 200 countries. The Indonesia offer drops to $0.98 per GB on the 50 GB plan, the third lowest price per GB in this comparison, behind voilà eSIM and Nomad. The global catalog remains practical if you are visiting several Southeast Asian countries in a single trip. The support, which is slow and only available in English, remains its main weakness. Read our review of Airalo.
7.2/10Holafly offers unlimited data in Indonesia, starting from $2.55 per day on the 30-day plan, and significantly more per day on shorter durations. Over a month, it is the most expensive unlimited plan in the rankings. Unlimited plans appeal to heavy users who do not want to track their quota. However, speed restrictions remain vague and no data-specific plans are offered: it is either unlimited or nothing. See our review of Holafly.
