The verdict

For most Australians on a Bali holiday of a week or more, a data-only Indonesia eSIM usually costs less than international roaming. Telstra, for example, lists Indonesia in its Zone 2 Day Pass at $10 a day with 2GB of data, so 7 days of daily use comes to $70 and 14 days to $140, according to Telstra at the time of writing. A data-only eSIM for the same days often comes in below that. Roaming is still the simpler pick if you need normal calls and texts on your Australian number all trip.

ShopBack Australia is a free app and website that returns cash on what you spend when you book or shop online at partner stores, including Klook and Trip.com. Booking through ShopBack lowers the cost of the trip, and you still book on the site you chose. Join ShopBack Australia free before you buy your Bali eSIM.

• Benchmark: Telstra Day Pass in Indonesia, $10 a day for 2GB, unlimited standard calls and SMS.
• eSIM option: a data-only Indonesia eSIM, such as Klook's 5G Telkomsel eSIM with validity from 1 to 30 days.
• Phone check: it must support eSIM and be unlocked.
• Before you check out: go through ShopBack, so your effective price is what you pay minus the cash that comes back.

Is an eSIM cheaper than international roaming for Bali?

Usually, yes, once your trip runs past a few days, because roaming in Indonesia is charged per day while an eSIM is one upfront price for the whole trip. The gap grows with every extra night in Seminyak, Ubud or Uluwatu.

Here are the published roaming figures from Telstra and Vodafone, at the time of writing:

Provider	What it costs in Indonesia	What you get	Source
Telstra Day Pass	$10 a day (Indonesia is Zone 2)	2GB data a day, unlimited standard calls and SMS; 2GB more for $10	Telstra international roaming page
Telstra pay as you go	$3 per MB of data; calls listed at $4.00 a minute for Indonesia	No daily cap on charges	Telstra international roaming page
Vodafone $5 Roaming	$5 a day in over 100 destinations, list varies	Your plan's included data, calls and texts; 1GB more for $5	Vodafone roaming page
Vodafone pay as you go	$1 per MB of data	Applies where $5 Roaming is not available or switched on	Vodafone roaming rates page

What that looks like for common Bali trip lengths on the Telstra Day Pass, used every day:

Trip length	Telstra Day Pass total
5 nights	$50
7 nights	$70
10 nights	$100
14 nights	$140

Telstra says you are charged the Day Pass only on days you use it, and that it can take up to 2 hours to activate, so switch it on before you fly. Vodafone says $5 Roaming is charged only on days you use your included data, make or receive a call, or send a text, and it can be used for up to 90 days a calendar year. Its destination list can change, so check Indonesia is on it in My Vodafone before you leave. Optus and other providers publish their own roaming rates, so look up yours too.

The pay as you go trap. If you land in Bali without a Day Pass or eSIM and your phone uses mobile data, pay as you go rates of $1 to $3 per MB add up fast. Turn off data roaming until you have a plan sorted.

When roaming is the better choice. If you are only in Bali for two or three days, need to take calls on your Australian number for work, or travel with a phone that does not support eSIM, a daily roaming pass is the simpler choice even if it costs more.

What is the best eSIM for Bali?

The best eSIM for Bali is a data-only Indonesia eSIM on a major local network, sized to the days and data you will actually use. A nationwide network matters if you plan day trips beyond the south, such as to Ubud or Nusa Penida.

As one example, Klook sells a 5G eSIM for Indonesia on the Telkomsel network. According to Klook's eSIM listing at the time of writing, it offers:

• Validity: 1 to 30 days
• Speed: 5G or 4G LTE
• Service type: data only
• Coverage area: all of Indonesia
• Confirmation: instant, so you can buy the night before you fly

How to choose your plan size:

1. Count your days. Match validity to your nights in Bali, plus a day for travel.
2. Estimate your data. Maps, Grab or Gojek rides, WhatsApp and booking apps use far less than streaming video or video calls. Hotel and villa Wi-Fi covers most heavy use.
3. Buy the smallest plan that covers both, and top up if you need more.
4. Check the start rule. Some plans count days from installation, others from first connection in Indonesia.

Other places Australians buy travel eSIMs include Airalo, Holafly and Nomad, and Australian providers such as Telstra, Vodafone and Optus sell roaming passes. For Bali stays and flights, Australians also book through Booking.com, Expedia and Agoda, and you can open each of those from ShopBack Australia too.

What are the best eSIM deals for Bali from Australia in 2026?

The best Bali eSIM deal in 2026 is the lowest total price for your days and data after the cash ShopBack returns, not the lowest headline price. A few ways to get there:

• Do not overbuy data. A light user on a 7-night trip often needs a small plan. Heavy social posting or hotspotting a laptop needs more.
• Match validity to your trip. With Klook listing validity from 1 to 30 days, pick the option closest to your stay rather than rounding up to a month.
• Check promo code terms first. The ShopBack Klook page says that if you use any promo, coupon or discount code, your whole order is not eligible on ShopBack. Read the terms on the store's ShopBack page before you apply a code.
• Buy the eSIM with the rest of the trip. If you are already booking a Bali hotel or tours on Trip.com or Klook, buying the eSIM there keeps everything in one account.
• Go through ShopBack before you pay. ShopBack works like a post-purchase discount on the order: you pay the store as normal, then cash comes back to your ShopBack account.

Real-time eSIM prices change often, so compare plans on the day you buy rather than relying on a price you saw weeks ago.

Klook vs Trip.com eSIM for Bali: how do they compare?

Klook and Trip.com both sell travel eSIMs to Australians, so the fair comparison is the same data and days on the same day, using the total price after ShopBack. Each has its own strengths.

	Klook	Trip.com
What it is	Travel platform for activities, transport, eSIMs, SIM cards and pocket Wi-Fi	Travel platform for flights, hotels, trains, transfers, car hire and eSIMs
Bali eSIM	5G Indonesia eSIM on Telkomsel, all of Indonesia, data only	eSIMs sold alongside Bali flights and hotels
Plan details shown	Network, validity (1 to 30 days), speed, coverage and service type on each listing	Read the coverage, data and validity on the product page before you pay
On ShopBack	The ShopBack Klook page names the 5G Indonesia (Bali) eSIM on Telkomsel as a participating eSIM	The ShopBack Trip.com page lists eSIM among its eligible categories
Before you pay	Go through the ShopBack Klook page	Go through the ShopBack Trip.com page

Klook suits travellers who want to see the local network and validity at a glance and also plan to book Bali activities such as tours, water parks or day trips. Trip.com suits travellers who want flights, the hotel and the eSIM in one account.

5. Switch on in Bali. On arrival, set the eSIM as your data line and turn on data roaming for that eSIM if the provider tells you to.
6. Keep your Australian SIM for texts. Leave it on for bank codes, with mobile data switched off on that line to avoid roaming charges.

How do I save on a Bali eSIM with ShopBack?

Before you check out, go through ShopBack to get a post-purchase discount on the order. The cash ShopBack returns lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles.

1. Sign in to ShopBack Australia on the app or website, or join free.
2. Open the ShopBack Klook page or the ShopBack Trip.com page.
3. Check the participating eSIM list or eligible categories, the live rate and the terms on that page.
4. Tap through, choose your Bali eSIM and pay in the same session.
5. The cash shows as pending, then confirms later, and you can withdraw it once confirmed.

Working out your effective price. Your effective price is what you pay minus the cash ShopBack returns. On a $20 eSIM at an illustrative 10%, $2 comes back, so the effective price is $18. Real rates change, so check the live rate on the store's ShopBack page before you buy.

Do the same for the rest of the trip. Booking through ShopBack lowers the cost of the whole Bali trip, and you still book on the site you chose: a villa on Trip.com, a Nusa Penida day trip on Klook, or a hotel on Booking.com, Expedia or Agoda. On a $1,500 Bali hotel and flight booking at an illustrative 5%, $75 comes back, so the effective price is $1,425. Check the live rate on each store's ShopBack page.
