What is the best eSIM for Indonesia in 2026?

voilà is the best eSIM for Indonesia in 2026. The price is $0.70 per GB on the Telkomsel network, which offers the best coverage across the archipelago, and activation takes just two minutes.

How much does an eSIM for Indonesia cost?

The price of an eSIM for Indonesia starts at $0.70 per GB at voilà, the lowest rate in this comparison, with a 50 GB plan at 31,40 € and a 20 GB plan at 15,10 €. Holafly offers unlimited data at $3.79 per day, the most expensive option.

Which network has the best coverage in Indonesia, in Bali, and across the islands?

Telkomsel is the network that covers Indonesia best, from Bali and Java to remote islands like Komodo, Flores, or Raja Ampat. The voilà eSIM uses this network, which guarantees you a connection where plans relying on secondary networks drop out.

How to activate your eSIM before leaving for Indonesia?

You install the eSIM before you leave by scanning a QR code from the provider's app. With voilà, installation takes two minutes and your line activates as soon as you arrive in Indonesia.

Does the eSIM work on all the islands (Bali, Lombok, Komodo)?

Yes. voilà works throughout all of Indonesia thanks to the Telkomsel network, from Bali, Java, and Lombok to the Gilis, Flores, and Komodo National Park. Your line activates as soon as you land at Denpasar's Ngurah Rai airport. The connection stays stable across major tourist sites; it might weaken in very remote areas or out at sea, just like any other network in the country.

Do you need to register your phone (IMEI) to use an eSIM in Indonesia?

No. Indonesian IMEI registration applies to phones used with a local SIM card, especially after a few months. A travel eSIM like voilà requires no declaration: you just scan the QR code and connect upon arrival, without having to go through customs or a local operator.

Does my usual mobile plan work in Indonesia?

Yes, but often at a high price. When you're abroad, your usual mobile plan charges for roaming, which can quickly get expensive once you go over a small included quota. A travel eSIM like voilà replaces that roaming with a local data plan at $0.70 per GB, with no overcharging or nasty surprises on your bill when you get back.

Does the eSIM work with 5G in Indonesia?

Yes. The voilà eSIM uses the Telkomsel network, which deploys 5G in Jakarta and Bali, and 4G across the rest of the archipelago. You'll automatically enjoy the best available speed wherever you are: if your phone is 5G compatible and you're in a covered area, the connection switches over without any special settings.

Do you need to register your SIM card with your passport in Indonesia?

With a local prepaid SIM card, yes: Indonesia requires registration (eKYC) in the traveler's name, passport required, often at a shop upon arrival. A travel eSIM like voilà saves you from all that: you just scan the QR code before you leave and you're connected as soon as you land, without needing to visit a shop or provide paperwork.

Methodology

Our ranking methodology

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.

The detailed ranking

The top 6 eSIMs for Indonesia in detail

1. voilà, the best eSIM for Indonesia
9.4/10
voilà comes out on top in this comparison. The eSIM relies on the Telkomsel network, which is by far the most extensive in the country. The result: whether you're in the rice fields of Ubud, on a ferry to the Gili Islands, or in the middle of Komodo National Park, you stay connected where other networks drop out. The price per GB remains the lowest in the comparison, with no commitment or hidden fees.
Coverage
voilà relies on Telkomsel, the most extensive of the four major Indonesian networks (ahead of Indosat IM3, XL Axiata, and Smartfren), with 4G everywhere and 5G in Jakarta and Bali. You'll get a signal as soon as you land at Denpasar's Ngurah Rai airport, across the entire island of Bali (Canggu, Ubud, Seminyak, Uluwatu, Sanur, Nusa Dua), in Jakarta and Yogyakarta, but also in Lombok, Flores, Komodo National Park, Sulawesi, and even up to the beaches of Raja Ampat. The connection stays solid where plans relying on secondary networks start to struggle as soon as you leave Bali.
Pricing
The price drops to $0.70 per GB on the 50 GB plan (€31.40), the lowest price per GB in the comparison. The 20 GB plan costs €15.10, and offers range from 3 to 50 GB, valid for 15 to 30 days depending on the volume. You pay for the data, nothing else: no hidden extra costs, and hotspotting is included.
Activation
Activation is simple: you buy and install your eSIM in two minutes via the voilà app. You scan a QR code before you leave, without having to mess around with a physical card. Your line activates as soon as you land in Indonesia, and you keep your usual number for calls and SMS.
Support
Multilingual support responds quickly, both before and during your trip. Your apps work normally: Gojek and Grab to get around, WhatsApp and FaceTime calls, Google Maps and Google Translate, ferry and diving apps, Instagram stories, and Netflix streaming in the evening all work without any blocks. You stay reachable and connected from the first day to the last.
Who is it for?
voilà suits every type of traveler: a relaxing getaway in Bali, a road trip through Java, diving in Komodo or Raja Ampat, or island hopping between Lombok and the Gilis. It's the best value for money for Indonesia in 2026, and the only one that guarantees reliable coverage even on remote islands.
Advantages
- Telkomsel network, the best coverage in the archipelago
- Lowest price per GB in the comparison
- Activation in two minutes, data sharing included
- Responsive multilingual support
Disadvantages

Local networks
A la carte data
Good price, no subscription
Nomad works on a pay-per-data basis, with no subscriptions, at about $2.00 per GB in Indonesia, with plans up to 50 GB for long stays. The app is clear and purchasing is fast.

Advantages
- Good data/price ratio, plans up to 50 GB
- Pay per data, no subscription
Disadvantages
- Support only in English
- Less reliable coverage outside of Bali and Java

3. Ubigi
$2.33/GB
Local networks
Data + top-up
Easy top-up in the app
Ubigi offers rechargeable data plans in Indonesia, at approximately $2.33 per GB. You can add data directly in the app without having to buy a whole new plan. The price per GB remains at the higher end of the comparison, support is limited to English, and the interface feels outdated compared to newer players. Read our review of Ubigi.
Advantages
- Direct top-up in the app, no need to buy a new plan
- Flexible plans, from 3 to 25 GB
Disadvantages
- One of the highest prices per GB
- Support only in English
