eSIM in Indonesia: which plan to choose in 2026?

How does an eSIM work in Indonesia, and is my phone compatible?

An eSIM is a digital SIM card already built into certain phones, tablets, and smartwatches: it replaces the small plastic card without changing how the mobile network works. After your purchase, the provider sends you an eSIM profile, usually in the form of a QR code and sometimes through its app. Your phone then downloads this profile and connects to a partner Indonesian network as soon as the activation requirements are met.

The main difference from a physical SIM is flexibility. You can buy your Indonesia eSIM plan from France, install it calmly over Wi-Fi before your flight, and keep your French SIM card in your phone. When you arrive in Denpasar or Jakarta, simply switch mobile data to the new line. This allows you to avoid queues, airport vendors, the paperwork sometimes required for a local SIM, and the risk of losing your usual card.

A travel eSIM is most often a data-only plan: it provides Internet access, but not necessarily an Indonesian phone number or traditional calls. You can still use WhatsApp, Signal, FaceTime Audio, Telegram, or Google Meet with your usual number. Before buying, check three key points: your device’s eSIM compatibility, whether it is unlocked, and when the plan’s validity begins. Installation can take place before departure; network activation, however, often has to wait until you arrive in Indonesia.

• iPhone XR, XS, and later models support eSIM in most countries. iPhones sold in the United States without a SIM tray work only with eSIMs; some devices sold in mainland China have specific limitations.
• With Samsung, the Galaxy S20 and later generations, many Galaxy Z Fold and Z Flip models, as well as some recent Galaxy A models, are compatible. However, eSIM availability depends on the exact model and the country where it was sold.
• Google Pixel 3 and later models generally support eSIM. For older models or phones purchased through certain carriers, checking in advance is still advisable.
• Motorola, Xiaomi, Oppo, Honor, and Sony now offer several compatible models, but not across their entire ranges. Never rely solely on the series name: check the technical specifications for your exact model.
• Your phone must be unlocked for all carriers. On iPhone, go to Settings > General > About > Carrier Lock; the message “No SIM restrictions” should appear.
• To check whether eSIM is available, look for “Add eSIM” or “Add mobile plan” in your network settings. The code **\*#06#** may also display an EID, the identifier specific to eSIMs, on many devices.

Should you choose an Indonesia eSIM or a Southeast Asia regional plan?

For a trip limited to Indonesia, a national eSIM is generally the most sensible choice: it often offers more data for your budget and may use a better-known local network. This is the option to favor for two weeks in Bali, a Java–Bali–Lombok itinerary, or a long stay in one region. However, check that the entire archipelago is covered by the plan, not just the main islands.

A regional Asia eSIM becomes more appealing if your ticket includes several countries: Singapore before Bali, Kuala Lumpur on the way back, or an extension to Thailand, Vietnam, the Philippines, or Cambodia. You keep the same eSIM profile and avoid a new installation at every border. This is particularly convenient for a Jakarta–Singapore–Bangkok itinerary or a backpacking trip through Southeast Asia.

This convenience comes with a trade-off: regional data often costs more per gigabyte, and the network partner may differ from one country to another. Read the exact list of included destinations, since “Asia” does not automatically mean that every Asian country is covered. Also check that the data allowance is shared across all countries and that Indonesia is not subject to a specific restriction.

• Choose an Indonesia-only eSIM if more than 80% of your trip takes place in the archipelago.
• Opt for a regional eSIM for a stopover of several days in Singapore, Malaysia, or Thailand, rather than combining several small plans.
• Check the country list before payment: “Asia-Pacific” plans do not all include the same destinations.
• For a simple airport layover with Wi-Fi available, an Indonesian national eSIM is often sufficient.

What do recent reviews reveal about travel eSIMs in Indonesia?

Traveler feedback is generally very positive about the ease of arrival: having Internet access as soon as you leave the plane makes it easier to order a Grab, convert currency, contact your accommodation, and access maps. Many travelers also appreciate keeping their French SIM in place, especially when they need to receive a banking code or remain reachable on their usual number.

Criticism rarely concerns eSIM technology itself; it usually involves details that were not carefully read before purchase. The most common issues are validity beginning at installation rather than at the first connection, a plan advertised as unlimited but subject to a fair usage policy, or limited hotspot access. Customer support becomes crucial if users discover these rules after arriving.

Coverage also creates sometimes unrealistic expectations. An eSIM rated very highly in Canggu may perform poorly on a remote beach in Flores, simply because the local network is weak there. The most useful reviews specify the island, city, network partner, phone model, and type of use. Conversely, be wary of universal promises of perfect connectivity throughout the archipelago.

• Recurring positive point: connection available upon arrival without changing SIM cards.
• Recurring positive point: easy usage monitoring and top-ups through an app or customer portal.
• Watch out: “unlimited” may include reduced speeds after intensive use or a hotspot restriction.
• Watch out: read the activation procedure and refund terms before scanning the QR code.

Can I keep my number, make calls, and share my connection with an Indonesia eSIM?

Yes, you can generally keep your French number while using an Indonesia eSIM for Internet access through Dual SIM mode. Set the eSIM as your mobile data line and leave your physical SIM, or your French eSIM, active for calls and SMS if necessary. Be aware that receiving an SMS is often free, but incoming and outgoing calls or certain messaging services may trigger roaming charges from your French carrier. Check its terms before departure.

Most travel eSIMs are data-only. They therefore do not assign a standard Indonesian number and may not allow you to call a restaurant, driver, or clinic over the cellular network. In practice, WhatsApp works with your usual number without any changes as long as you have Internet access. Grab, Gojek, Google Maps, airline apps, and VoIP calls will also work normally.

Hotspot access is essential if you work from a computer or want to connect a tablet. Most fixed-data plans allow it, but some unlimited plans restrict, cap, or disable it. Check this rule before buying. Keep in mind that a computer can use several gigabytes in a few hours through updates, cloud services, photo backups, or an HD video conference.

If you are approaching your limit, use the hotel Wi-Fi for large files first, disable automatic backups, and buy a top-up before you are completely disconnected. With most providers, a new plan is added to the same eSIM profile, but this is not universal: some require the purchase of a second plan. Once the data allowance is exhausted or validity has ended, Internet access stops even if you still have travel days remaining.

• Set the Indonesia eSIM as your default data line and disable automatic mobile data switching to your French line.
• Keep your WhatsApp number: do not create a new account or enter a new number in the app.
• To receive important SMS codes, leave your French line active, but turn off its data and roaming.
• Before departure, disable automatic updates, iCloud or Google Photos backups over mobile data, and automatic video playback.
• For a hotspot, test connection sharing at the hotel before a day of remote work or a trip to an island.
