The Complete Bali eSIM Guide for travellers from Australia: Everything You Need to Know Before You Fly

Planning a Bali (or wider Indonesia) trip from Australia and want reliable, affordable mobile data from the moment you land? You’re in the right place. This guide is written in the same practical, no‑nonsense style you’ll find across the Why Balisim articles—clear steps, local know‑how, and zero fluff. We’ll cover how eSIMs work for Indonesia, the best options for Australians, why a local eSIM usually wins, how to activate before you fly, device requirements, local rules, top‑ups, and more.

Who this guide is for

Whether you’re here for surf, wellness, work, or a month‑long island hop, staying connected should be easy. This guide is for Australians who want to skip airport queues, get a proper +62 number for local apps, and enjoy dependable coverage without paying roaming premiums. Let’s start with a few Australia‑specific tips to set you up for success.

Australia‑Specific Considerations When Getting an eSIM for Bali

Before you choose a plan, it helps to understand a few Australia‑specific details: device compatibility, how to set up dual‑SIM properly, what coverage to expect in Bali, and whether you’ll need a local number for everyday life on the island.

Device support and setup

    • Most AU iPhones (XS or newer) and flagship Samsung models support eSIM. AU iPhone 14/15 have a SIM tray and also support eSIM.

    • Keep your AU SIM active for calls/SMS (bank OTPs) and set the Indonesian eSIM as your data line.

    • Important: For this local eSIM solution, Google Pixel phones are not supported.

Coverage realities

    • Expect strong 4G in Canggu, Seminyak, Uluwatu, Ubud, Sanur, and Kuta; 5G exists but isn’t crucial for most travellers.

    • Telkomsel typically delivers the most consistent island‑wide experience, including more remote pockets and island day trips.

Do you need a +62 phone number?

    • Essential for Gojek/Grab, local OTPs, restaurant callbacks, and many bookings.

    • Many international eSIMs are data‑only; local eSIMs typically include a +62 number.

Queue‑free arrival

    • Pre‑activate from Australia to avoid airport lines and go online as soon as you deplane.

Pro tip: On iPhone, set your AU line to “Calls & SMS only” and leave Data Roaming off; set the Indonesian eSIM as your Mobile Data line. That gives you bank OTPs without surprise roaming data charges.

With the basics sorted, the next step is choosing how you want to connect—roaming, an international data eSIM, or a local Indonesian eSIM.


Typical Indonesia eSIM Provider Options from Australia

There are three common ways Australians connect in Indonesia: stick with AU roaming, install an international travel eSIM, or get a local Indonesian eSIM. Each balances convenience, cost, and features differently.

Australian carrier roaming (Telstra/Optus/Vodafone)

    • Pros: Zero setup; keep your +61 number and plan.

    • Cons: Daily fees add up quickly; costly for week‑long trips or heavy data use.

    • Best for: Very short trips where convenience beats cost.

International travel eSIMs (e.g., Jetpac, Airhub, Nomad, Airalo, SimOptions)

    • Pros: Install before you fly; auto‑activate on arrival; sharp pricing.

    • Cons: Often data‑only (no +62 number); some don’t use Telkomsel, which can mean patchier coverage around Bali.

    • Best for: Travellers who only need data and won’t rely on local‑number OTPs.

Local Indonesian eSIMs

    • Pros: +62 number included; stronger national coverage (often Telkomsel‑backed); priced for Indonesia; simple top‑ups.

    • Cons: Requires passport/IMEI pairing; eSIM/QR is single‑device only.

    • Best for: Most Australians who want seamless app access, reliable coverage, and better value.

Pro tip: If you’ll be using Gojek/Grab on day one, choose a local eSIM with a +62 number and activate before you fly—you’ll walk past the airport lines and hail a ride immediately.

Next, let’s look at why a local eSIM usually delivers the smoothest Bali experience.

Why a Local Indonesian eSIM Is Usually Better

Bali works best with a local number and a network that covers where you’ll actually go. A local eSIM ticks both boxes—and keeps costs predictable.

A real +62 phone number

    • Required for Gojek/Grab and many OTP‑based services.

    • Makes everyday logistics simpler—drivers and venues can call or WhatsApp you locally.

Coverage where it counts

    • Telkomsel is generally the safe bet island‑wide and across popular side trips.

    • Fewer dead spots when you venture beyond the main beach towns.

Value and flexibility

    • Tourist plans often include 20–30 days from your arrival date, with national data on 3G/4G/5G.

    • Top up easily while your IMEI remains active (e.g., up to 90 days with XL), ideal for extended stays.

Pro tip: If you plan day trips to Nusa Penida or northern Bali, pick a Telkomsel‑backed option to minimise dropouts on the road and at viewpoints.

Since timing can make or break your arrival, let’s talk about why pre‑activating before you fly is a game‑changer.

 

Why You Should Get a Local eSIM and Set It Up Before You Fly

Arrivals at Denpasar can be busy, and telecom counters often have queues. Pre‑activation means your phone is ready to go as soon as the cabin door opens.

What pre‑activation delivers

    • Online immediately to message your villa, navigate, or order a car.

    • No rushed paperwork; complete the form and scan your QR calmly at home.

Key facts at a glance

    • Validity: Typically 20–30 days from your arrival date.

    • Single‑device: eSIM/QR is tied to one device and cannot be reused.

    • Passport limit: One passport can register up to 3 eSIMs.

Pro tip: Landing late? Pre‑activation is even more valuable—skip closed counters and avoid after‑hours surcharges from unofficial sellers.

With timing locked in, let’s compare what actually differs between local eSIM options so you can pick with confidence.

Comparison of Local Indonesian eSIM Options

Local eSIMs differ by network, validity, IMEI rules, whether you get a +62 number, and how top‑ups work. Matching these to your itinerary is where the value really shows.

What to compare

    • Network: Telkomsel vs XL vs Indosat/IM3 vs Tri/Three vs Smartfren (Telkomsel usually leads in Bali).

    • Validity: Most tourist plans run 20–30 days from arrival.

    • IMEI window: Example—XL eSIM active 30 days; IMEI valid up to 90 days.

    • Phone number: Ensure a +62 number is included by default.

    • Top‑ups: Confirm availability and process.

Helpful references

Pro tip: If you’re mixing work and play, choose a plan with a comfortable buffer. Navigation, uploads, and hotspotting use more data than you think.

Once you’ve chosen your plan, installing and activating it from Australia only takes a few minutes—here’s how.

 

How to Activate a Local eSIM Before Arriving

Activation is a two‑step flow: submit the activation form (passport + IMEI) and install the eSIM on your device. Do it at home for a faster, calmer arrival.

Step‑by‑step

    • Check compatibility and unlock status in your phone settings.

    • Purchase your plan and submit the pre‑arrival activation form.

    • Install the eSIM via QR scan or manual entry.

    • Set the Indonesian eSIM as your data line; turn off data roaming on your AU line.

    • Land, attach to the network, and receive your +62 number.

Detailed guides

Pro tip: Take a screenshot of your QR code and activation details (and save them to Files) so they’re handy even if airport Wi‑Fi is spotty.

With installation handled, double‑check your handset’s compatibility and unlock status so nothing derails your departure day.

 

Device Requirements for Australians

A smooth eSIM experience starts with a compatible, unlocked phone. Most recent Australian iPhones and Samsung flagships are ready out of the box, but a quick check now avoids airport troubles later.

Compatibility & unlock checks

    • iPhone: Settings > General > About > Carrier Lock (look for “No SIM restrictions”); confirm Add eSIM in Settings > Mobile/Cellular.

    • Android (Samsung): Check SIM Manager/Connections for eSIM support.

    • Important: Google Pixel phones are not supported by this local eSIM.

Helpful resources

Pro tip: Travelling as a couple? One passport can register up to three eSIMs—set up both phones at home and hit the ground running together.

Once your device checks out, understanding Indonesia’s simple registration and IMEI rules will help you plan validity and top‑ups with confidence.


Local Rules You Should Know (Registration, IMEI, Validity)

Indonesia’s rules are straightforward: verify identity, pair your device, and use your plan within its validity window. Providers guide you through this during activation.

What to expect

    • Registration: Provide passport details during activation.

    • IMEI pairing: Binds your eSIM to your device for security and continuity.

    • Validity: Tourist plans typically 20–30 days from arrival.

    • XL example: eSIM active 30 days; IMEI valid up to 90 days.

    • Limits: One passport can register up to 3 eSIMs; eSIM/QR is single‑device only and cannot be reused.

Pro tip: If you think you’ll extend your stay, set a reminder for when your IMEI window ends (e.g., 90 days on XL) so you can top up or plan a fresh activation in time.

With the rules clear, let’s look at day‑to‑day management—checking your balance and topping up when you need more data.

 

Data Top‑Up Capabilities

Running low doesn’t have to interrupt your day. As long as your IMEI remains active, you can add data and keep your number without starting from scratch.

Practical tips

    • Choose a plan that matches real usage—maps, rides, social uploads, and hotspotting add up.

    • Check your balance regularly and top up before you hit zero to avoid any temporary slowdowns.

How to check and top up

Pro tip: If you work remotely, schedule top‑ups in the morning before calls; café Wi‑Fi can vary, and mobile data is often the more reliable backup.

With top‑ups sorted, let’s wrap up with a quick checklist and final recommendations so you can book with confidence.

 

Quick Reference: Key Facts and Final Recommendations

Here’s a screenshot‑friendly checklist to save before you fly:

  • Validity: Typically 20–30 days from your arrival date.

  • Activation: Complete the pre‑arrival activation form for instant connectivity.

  • Single‑device: eSIM/QR is unique and bound to one device; cannot be reused.

  • Passport limit: Up to 3 eSIMs per passport.

  • XL specifics: eSIM active 30 days; IMEI valid up to 90 days for top‑ups.

  • Top‑ups: Available while IMEI is active; plan ahead for heavy usage.

  • Networks: National data works on 3G/4G/5G across Indonesia.

  • Phone number: You receive a +62 number on activation.

Final recommendations for Australians:

  • Choose a local Indonesian eSIM if you want a +62 number and reliable Bali coverage (Telkomsel‑backed options are the strongest island‑wide).

  • Keep your AU SIM on for calls/SMS and bank OTPs, but switch data to the Indonesian eSIM and turn off AU data roaming.

  • Pre‑activate in Australia to skip airport queues and start your trip connected.

With your plan selected and activation complete, you’re set to arrive in Bali with connectivity sorted—leaving you free to enjoy the beaches, cafés, and adventures ahead.
