Best eSIM for Indonesia: Compare Plans for International Travellers

What Is the Best eSIM for Indonesia?

It depends on your route, trip length, data needs, and whether you need a local phone number. This guide compares BaliSIM, Airalo, Saily, and Nomad using their own pages. BaliSIM publishes this article, so we report every provider the same way and don't name an overall winner.

⚡ Quick Answer: Pick by Need

No provider wins for every traveller.

Data only, no registration: Airalo, Saily, and Nomad's reviewed product pages do not describe the same passport-and-IMEI registration process listed by BaliSIM. Compare them at your data size.
A +62 number and call minutes: BaliSIM's plans include them, with registration required. Nomad says some of its plans include a number.
Several islands: choose a plan whose terms name every island. No plan guarantees signal on remote islands or at sea.
A short, light trip: small plans cost about the same everywhere, roughly $4 to $5 for 1 GB.

What to Look for When Choosing an Indonesia eSIM

Network coverageThe eSIM borrows a local operator's network. Check which one, and how it performs on your route. Coverage can be limited in remote areas and at sea.

Data allowanceMatch it to your usage. Maps and messaging need far less than streaming or tethering.

Plan validityThe plan should last as long as your trip. Check whether validity starts on purchase or on first connection.

Price and valueCompare price per GB at the same size, not just the lowest advertised price.

Local number and callsMany travel eSIMs are data-only. If you need to phone drivers or hotels, check for a number and minutes.

Device compatibilityYour phone must support eSIM and be carrier-unlocked. Most recent iPhone, Samsung Galaxy, and Google Pixel models do, but check the provider's list.

Installation and activationSome providers use a QR code, others an app. Registration steps, where required, can add time.

Best eSIM Providers for Indonesia

The table lists plans whose details we confirmed on official pages on November 1, 2026. "Not specified" means the page didn't state it.

Saily Indonesia	1 GB $4.79; 3 GB $8.99; 5 GB $13.99; 10 GB $21.99; 20 GB $35.99; unlimited 15 days $48.99	7 days (1 GB); 30 days (3 to 20 GB); unlimited 5 to 30 days	Not named for the plan	No Indonesian number; calls through apps only. Its phone-number feature is a US number

BaliSIM's prices include the discount shown on each page, and its larger sizes have their own prices on the product pages. BaliSIM plans require passport and IMEI registration, while Airalo, Saily, and Nomad describe no such step. We couldn't confirm Airalo's fixed-plan price list on its official page.

Value is more than price per GB

Here is a snapshot at comparable sizes, with the factors that change what a plan is actually worth.

Plan	Price per GB	Validity	Number and calls	Registration	Coverage note
BaliSIM XL, 18 GB	~$0.73 ($0.85 at list price)	Data 30 days	+62 number, 5 minutes	Passport and IMEI	XL. Named Bali, with quotas listed as national
BaliSIM Telkomsel Nationwide, 38 GB	~$0.74 ($0.93 at list price)	Data 28 days	+62 number, 120 minutes	Passport, selfie, and IMEI	Telkomsel. National quotas
BaliSIM Telkomsel Bali, 13 GB	~$1.12 ($1.25 at list price)	28–30 days	+62 number, no minutes listed on this plan	Passport and IMEI	Telkomsel. Described as Bali and Lombok
Nomad, 20 GB	~$1.45	Confirm on Nomad's page	No phone number. Data-only; calls through apps only.	None described	XLSMART / Telkomsel
Saily, 20 GB	~$1.80	30 days	None; apps only	None described	Network not named. Plan covers Indonesia
Airalo	Not verified	Per package	None	None described	Indosat listed as primary

A plan with a number and call minutes isn't comparable to a data-only plan, a registration step costs time, and validity decides whether the data lasts your trip. Network names don't prove coverage either. Opensignal's July 2026 report doesn't show one operator winning every measure, so check your own locations rather than trusting a network label. None of this makes any provider the cheapest overall.

Which Indonesia eSIM Is Best for Different Travellers?

Best for Bali visitors

BaliSIM Bali Visitor plans, or a data-only plan BaliSIM's Telkomsel and XL Bali plans give you a number, call minutes, and hotspot, but need registration. Airalo, Saily, and Nomad are simpler if you only need data.

Best for budget-conscious travellers

Compare the same size across providers Small plans cost roughly the same everywhere. Larger plans are where price per GB separates, so compare at your size and weigh the registration step. Short unlimited plans cost more per day.

Best for multi-island travel

A plan that names every island Saily says its plan works anywhere in Indonesia, and Airalo and Nomad sell Indonesia plans. For BaliSIM, the Nationwide plan is the one listed beyond Bali and Lombok (see the note below). No plan guarantees signal on remote islands, in parks, or at sea.

Best for a local phone number

BaliSIM Among these four, BaliSIM's pages are the ones that list a +62 number and call minutes. Nomad says only Nomad's Indonesia eSIM is data-only and does not include a local phone number, traditional voice calls, or SMS, and Saily's number feature is a US number.

What each BaliSIM product covers

Telkomsel Bali Visitor: described for Bali and Lombok, and valid if you enter Indonesia through Bali. We don't present it as covering Java, Flores, or other islands.
XL Bali Visitor: a Bali-named product. Its page lists quotas as national, but we don't present it as an Indonesia-wide plan.
Telkomsel Indonesia (Nationwide): the product BaliSIM lists for trips beyond Bali and Lombok, with 38 or 103 GB and national quotas. Remote areas, parks, and sea routes can still lack signal.

If you're not sure which suits you, BaliSIM's eSIM comparison page sets its own plans side by side.

How to Buy and Activate an Indonesia eSIM

The basic steps are similar everywhere. The details differ by provider.

📱 From purchase to connected

Check your phone. It must support eSIM and be carrier-unlocked. Use your provider's compatibility list, such as BaliSIM's supported phones list.

Pick a plan that matches your destinations, data needs, and trip length.

Complete any registration your provider requires.

Install the eSIM by QR code, app, or manual entry, following the provider's instructions.

Switch it on in Indonesia. Select the eSIM for mobile data and follow the provider's roaming instructions.

Contact support if it won't connect.

How it works for each provider

Provider	What its pages say
BaliSIM	Complete an online activation form with passport and IMEI photos (plus a selfie on the Nationwide plan), ideally before arrival. The eSIM arrives by email, and the Nationwide plan is delivered one day before your arrival date. See the installation guide and troubleshooting guide.
Airalo	The Help Center has device-specific install guides, such as installing directly on iOS. Per its Indonesia guide, validity starts when the eSIM connects to a supported network. No registration step is described.
Saily	Buy a plan, install the eSIM through the Saily app, and enable data roaming. The plan activates automatically when you arrive, and plans have a 180-day window to activate.
Nomad	The plan page we reviewed doesn't detail the install steps. Follow Nomad's instructions after purchase.

Frequently Asked Questions

Which eSIM is best for Indonesia?

Start with two questions. Do you need a +62 number or call minutes? If so, look at BaliSIM, or ask Nomad which of its plans include a number. Will you travel beyond Bali and Lombok? If so, pick a plan that names every island. Then compare price per GB, validity, and registration at your data size.

Does an Indonesia eSIM work in Bali?

Yes, in general. Saily's page says its Indonesia plan covers the whole country and that eSIMs work well in tourist areas like Seminyak, Ubud, and Canggu, with speeds varying in remote villages. For Bali-named plans, check the stated area. Remote spots can still have weak signal, whichever eSIM you use.

Can tourists get an Indonesian phone number?

Yes, with some plans. BaliSIM's plans include a +62 number and call minutes, but they require passport and IMEI registration. XL's tourist eSIM also registers a prepaid number for foreign passport holders. Airalo and Saily plans are data-only. None of the pages we reviewed specify an SMS allowance, so ask before relying on SMS.

How much data do I need for Indonesia?

Check what your phone uses in an ordinary week at home in its mobile data settings, then add a buffer for maps, ride-hailing, and photo uploads. Tethering a laptop or streaming video multiplies usage. BaliSIM's data usage calculator can help, and a plan that lasts your whole trip matters as much as its size.

Is an Indonesia eSIM better than a physical SIM?

It depends on what you value. An eSIM can be installed before you land and lets you keep your home SIM active for calls, as BaliSIM's FAQ notes. A physical SIM includes a local number as standard but has to be collected or delivered; BaliSIM lists a Telkomsel physical SIM with hotel delivery. Compare price, number, and convenience.

Can I use an Indonesia eSIM on an iPhone and Android?

Yes, if your phone supports eSIM and is carrier-unlocked. On iPhone, the Add eSIM option is under the Settings mobile service or cellular menu. On Android, the path varies by brand, often under network or SIM settings. Some providers, such as Saily, install through their app. Check your device against the provider's compatibility list.
