Is Airalo Good for Bali? An Honest Review vs Telkomsel (2026)

We are an authorized Telkomsel retailer and we set up eSIMs for travelers every day, so we are not neutral — check our numbers against Airalo's own pages. Airalo prices and the network list come from Airalo's own app; the fair use and refund terms come from Airalo's published policies. All checked 26 August 2026.

First, a 60-Second Guide to Indonesian Networks

If you have never been to Indonesia, "Telkomsel" and "Indosat" are just two unfamiliar words. Most travellers assume they are interchangeable, like Vodafone and O2 at home.

They are not. And the difference does not show up in Seminyak. It shows up on the road to Amed.

There are three operators. That is the entire market.

#	Operator	Subscribers	Who owns it
1	Telkomsel This is what we sell	157.6 million	Telkom Indonesia, the state telecoms company (69.9%) and Singtel (30.1%)
2	Indosat Ooredoo Hutchison This is what Airalo uses	93.7 million	Ooredoo Hutchison Asia (65%)
3	XLSmart XL and Smartfren, now merged	73 million	Axiata and Sinar Mas (34.8% each)

Subscriber figures: Telkomsel Q3 2025, Indosat and XLSmart Q4 2025.

Telkomsel has 68% more subscribers than Indosat and roughly half of all mobile users in the country. It has been number one for its entire existence.

Why the biggest one matters to a tourist

Not for prestige. For towers.

Indonesia is 17,000 islands stretched across 5,000 kilometres. Building coverage here is brutally expensive, and only the operator with the most subscribers can justify putting a tower somewhere with two hundred residents and a dive shop.

What independent testers found in 2026

We sell Telkomsel, so do not take our word for it. Two organisations measure mobile networks worldwide from real phones, and both published Indonesia results at Mobile World Congress in 2026.

• Ookla Speedtest Awards 2026 gave Telkomsel five awards, including Fastest Mobile Network and Best Mobile Coverage, from real user measurements across Q3–Q4 2025. Ookla publishes country results at speedtest.net/awards.
• Opensignal 2026 placed Telkomsel ahead on 11 experience metrics, covering speed, video, gaming, coverage and 4G/5G consistency. Their Indonesia reports are free to read.

Neither sells SIM cards. Neither cares which one you buy.

👉 The full network guide: which of the 13 eSIM brands uses which operator

Airalo Does Not Use Telkomsel

Now the specific part. Open the Airalo app, go to the Indonesia eSIM, and tap Networks. Airalo tells you plainly:

No Telkomsel. Anywhere on the list. You are buying number two, not number one.

And here is the part that looks like a choice but is not

Two network names sounds like a safety net. If one is weak, the phone hops to the other.

It does not work that way here. Tri (3) and Indosat merged in January 2022 to form Indosat Ooredoo Hutchison. They are one company running one integrated network.

So an Airalo eSIM in Indonesia gives you one operator group, with no Telkomsel fallback at all.

	Telkomsel (us)	Indosat + Tri (Airalo)
South Bali — Kuta, Seminyak, Canggu	✅ Strong	✅ Strong
Central Ubud	✅ Strong	✅ Usually fine
Ubud valleys and rice terraces	✅ Strong	⚠️ Patchy in the gorges
Nusa Penida, Amed, Sidemen	✅ Strong	⚠️ Unreliable
Fast boats and ferry crossings	✅ Holds signal longest	⚠️ Drops early
Gili Islands, Lombok interior	✅ Strong	❌ Gaps
Flores, Komodo, Sumba	✅ Widest reach	❌ Gaps

To be fair to Indosat

In earlier Opensignal reporting, Indosat — after merging with Hutchison — outperformed Telkomsel on some speed measures in rural areas and outside Java. We published that and we are not deleting it now that it is inconvenient.

What changed is that in the 2026 round Telkomsel led on the metrics both testers publish. So the honest position is that Indosat is a genuinely good network that has closed ground, and Telkomsel is still ahead — most importantly on coverage.

And coverage is what decides your holiday. A speed test only runs where there is already a signal. If there is no Indosat tower on the road to Amed, it does not matter how fast Indosat is somewhere else.

One more thing worth knowing, because Airalo says it themselves: their fair use policy warns that the underlying networks "may apply traffic management during busy periods," causing slowdowns separate from the daily cap and outside Airalo's control. That is what being a roaming guest means in practice.

Every Plan, Priced

Airalo sells two ranges in Indonesia: fixed-data plans and unlimited. Here is all of it, including the plans where they beat us.

Fixed-data plans against ours

Airalo plan	Their price	Closest plan of ours	Our price	Verdict
1 GB — 3 days	$4.50	we sell nothing this small	—	Airalo wins
3 GB — 3 days	$8.00	we sell nothing this small	—	Airalo wins
3 GB — 7 days	$8.50	we sell nothing this small	—	Airalo wins
5 GB — 7 days	$12.00	we sell nothing this small	—	Airalo wins
10 GB — 7 days	$19.00	10 GB — 30 days	$13	32% less, and 23 more days
5 GB — 15 days	$13.00	10 GB — 30 days	$13	same price, double the data
10 GB — 15 days	$20.00	10 GB — 30 days	$13	35% less
20 GB — 15 days	$34.00	21 GB — 30 days	$17	50% less, 1GB more
5 GB — 30 days	$13.50	10 GB — 30 days	$13	cheaper and double the data
10 GB — 30 days	$21.00	10 GB — 30 days	$13	38% less
20 GB — 30 days	$35.00	21 GB — 30 days	$17	51% less, 1GB more
50 GB — 30 days	$49.00	45 GB — 30 days	$26	47% less, but 5GB less data
50 GB — 30 days	$49.00	83 GB — 30 days	$37	$12 less and 33GB more

Look at where the yellow rows stop. Airalo only beats us under $12. Every plan above that, we are cheaper — usually by a third to a half.

And note the 5GB rows. Airalo charges $13 for 5GB over 15 days and $13.50 for 5GB over 30 days. We charge $13 for 10GB over 30 days. Same money, twice the data, longer validity.

Unlimited plans against ours

Trip	Airalo Unlimited	Best plan of ours	You save
3 days	$11	$13 (10GB)	Airalo wins by $2
5 days	$19	$13 (10GB)	$6 — 32%
7 days	$27	$13 (10GB)	$14 — 52%
10 days	$34	$13 (10GB)	$21 — 62%
15 days	$48	$17 (21GB)	$31 — 65%
30 days	$69	$26 (45GB)	$43 — 62%

The crossover is about 3.5 days. Book a fourth night and the maths has already flipped.

What Is the Cap on Airalo's Unlimited Plan?

This is the question people type into Google right before they buy, so here it is straight, from Airalo's own published fair use policy.

The detail almost everyone gets wrong — including us, until we checked

Your daily allowance does not reset at midnight. Airalo's policy is explicit: it resets every 24 hours, counted from the moment you activated the eSIM.

We had this wrong on this page until 26 August 2026, when we read the policy properly. It is corrected now, and we are telling you rather than quietly editing it.

Credit where it is due

We are competing with Airalo and we still want to say this clearly. Airalo is the most honest of the big unlimited sellers. The number is written in plain text on their own site, in language you can search, before you pay.

Brand	Do they publish the limit?	Daily or whole plan?	Speed after
Airalo	✅ Yes — 3GB a day, in plain text	⚠️ Resets 24h after activation	1 Mbps
Ubigi	⚠️ A range, yes. Per country, only as an image	✅ Whole plan	2 Mbps
Holafly	❌ No number before you buy	⚠️ Resets every day	256 kbps – 1 Mbps

Airalo wins on transparency. Ubigi wins on structure, because a whole-plan limit lets you have one heavy day without being punished for it. Holafly loses both.

Now do the maths on that 3GB

Here is the thing almost nobody works out.

If you somehow used every single gigabyte Airalo will give you at full speed for 30 days, that is 3GB × 30 = 90GB, for $69.

Unlimited sells you a ceiling you will never touch. That is the whole business model.

What does 1 Mbps feel like?

At 1 Mbps	Works?
Google Maps, WhatsApp, email	✅ Fine
Instagram and TikTok	⚠️ Slow to load
Video calls	⚠️ Rough — Airalo says "lower-quality"
Netflix or YouTube in HD	❌ No

Hotspot: Airalo Does Not Cap It

We went looking for a hotspot restriction here because Holafly has a severe one. Airalo does not. Their fair use policy says it outright:

That is a clear answer and Airalo deserves credit for giving it. On this one point, they, Ubigi and we are all the same.

Provider	Hotspot allowance
Airalo	✅ No limit on tethering or device count
Ubigi	✅ Uncapped on all plans
Balitel (Telkomsel)	✅ No separate limit. Your data is your data.
Holafly prepaid	❌ Capped ~500 MB – 1 GB a day, separate from phone data

So if hotspot is your deciding factor, this is not a reason to pick us over Airalo. It is a reason to avoid Holafly.

The one caveat that still applies to Airalo: the 3GB daily cap covers everything, phone and tethered devices together. Work off a laptop for a morning and you can reach it before lunch, then sit at 1 Mbps until your activation hour comes round again. Our plans have no daily ceiling at all — use 12GB on Tuesday if you like.

Where Airalo Genuinely Wins

We sell Telkomsel eSIMs, so we are biased. Airalo is still the biggest travel eSIM company in the world for reasons that are mostly good ones.

1. Short trips. This is not close.

1GB for 3 days at $4.50. 3GB for 3 days at $8. 3GB for 7 days at $8.50. 5GB for 7 days at $12.

We sell nothing under 10GB. If you are in Bali for a long weekend in Seminyak and you need maps and WhatsApp, buy Airalo. We would be taking money for gigabytes you will never open.

2. They publish their fair use limit

Covered above, and it deserves repeating. Airalo tells you 3GB a day before you pay, and tells you exactly when it resets. Holafly tells you nothing.

3. Uncapped hotspot, stated plainly

No tethering limit and no device limit, written into their policy. Most of the market either caps it or stays quiet.

4. They publish their network list too

Everything in the network section above came from Airalo's own app. Nine of the thirteen brands we checked will not tell you which Indonesian network you are buying. Airalo will, on a screen anyone can open.

We are using that openness to argue against them. That is a slightly unfair reward for being honest, and we would rather say so than pretend otherwise.

5. Multi-country travel

If Bali is one stop on a route through Thailand, Vietnam and Singapore, one Airalo regional plan is simpler than four local SIMs. That is a real advantage and we cannot match it.

6. The app, and instant store credit

Airalo's app is the best in the category. Top-ups, usage tracking, and support all live in one place. Refunds to Airmoney store credit are instant, which is genuinely useful if you just bought the wrong plan.

Where Airalo Falls Short in Bali

1. It is the second network, not the first

The main one. Indosat and Tri are the same company, so you have one network group — 93.7 million subscribers and about 90% population coverage, against Telkomsel's 157.6 million and 97%.

If your whole trip is Seminyak, Canggu and the airport, this will never bother you. If you are taking the fast boat to Nusa Penida or driving to Amed to dive, it will.

2. No Indonesian phone number

Airalo is data only. No +62 number, no Indonesian SMS.

Grab and Gojek send a verification code by SMS when you create an account. Without an Indonesian number the code never arrives. Same for QRIS payment apps and Indonesian banking apps.

If you already have a Grab account verified at home, you can use it over Airalo's data. If you need a new account, you are stuck.

3. Short validity on the cheap-looking plans

Airalo's 7-day and 15-day plans look cheap next to a 30-day one, but they expire while you are still using them. Their 10GB/7-day is $19. Our 10GB runs 30 days for $13. You are paying 46% more for 23 fewer days.

4. The daily reset punishes one heavy day

A 3GB daily cap sounds generous until you have one long travel day of hotspotting, a film on the flight home, or a two-hour video call with the family. You hit the wall once and you are at 1 Mbps until your activation hour comes round again — which, as above, is not midnight.

Fixed-data plans do not do this. Use 6GB on Tuesday and 200MB on Wednesday. Nobody stops you.

5. You are a roaming guest, not a local customer

Airalo connects you through Indosat as a visitor. We put you on Telkomsel directly, as a customer with your own number.

When a tower gets busy — 7pm in Canggu, a beach club on a Saturday — roaming traffic can be deprioritised behind local traffic. Airalo's own policy acknowledges this network traffic management and disclaims responsibility for it.

How Much Data Do You Actually Need?

Nobody knows how many gigabytes they use. Everybody knows how many days their trip is. So start from days.

That is the whole rule. No calculator, no app, no guessing.

Why one gigabyte?

What you are doing	Data used
Google Maps, one hour of driving	about 5 MB
WhatsApp messages, all day	under 20 MB
Instagram, 30 minutes of scrolling	about 150 MB
One hour of Netflix or YouTube in HD	about 3 GB

Maps and WhatsApp are basically free. One hour of Netflix uses three days' worth of everything else. Notice that one hour of Netflix is also exactly Airalo's entire daily allowance.

Now pick your plan

Your trip	Normal use	Video most days
3–4 days	Airalo 3GB — $8	Our 10GB — $13
5–7 days	Our 10GB — $13	Our 21GB — $17
10 days	Our 10GB — $13	Our 21GB — $17
2 weeks	Our 21GB — $17	Our 45GB — $26
3 weeks	Our 21GB — $17	Our 45GB — $26
A month	Our 45GB — $26	Our 83GB — $37

When in doubt, go one size up. Running out on day nine is far more annoying than the four dollars you saved.

So Where Do You Actually Buy a Telkomsel eSIM?

You cannot buy one online from Telkomsel as a tourist. Their website sells eSIMs to Indonesian citizens, verified by national ID card and family card. Foreign residents with a KITAS permit must visit a service centre in person. Tourists hold neither document.

Where	Who runs it	Sorted before you fly?
GraPARI service centre in Bali	Telkomsel themselves	❌ In person only
Counters at Ngurah Rai airport	Third parties under Telkomsel branding	❌ Queue on arrival
Authorized retailer — this is us	Licensed businesses like Balitel	✅ Yes

We are both an online store and a real shop in Bali

Most sellers are one or the other. The cheap SIM shops in Canggu are physical only — you have to land, find them, and pay cash. The international eSIM apps like Airalo are online only. Airalo is AirGSM Pte Ltd, registered in Singapore; there is no Airalo counter anywhere in Indonesia.

We are both.

• Buy online before you fly. Order from home, send us your passport and IMEI, and we register everything while you are still packing. The QR code arrives on your WhatsApp. You land connected.
• Or come and see us. We are part of Diamond Handphone, trading in Bali since 1998, with five stores across Denpasar, Kuta, Seminyak and Canggu.

👉 The full explanation of why tourists cannot buy Telkomsel directly

An Honest Warning About a Local IP

Every comparison page you will read, including ours, is written by somebody selling something. So here is a real drawback of our product that we have not seen any local seller admit.

A Telkomsel line gives you an Indonesian IP address. That is the whole point — it is what makes you look like a local to the internet. It is also occasionally inconvenient.

What an Indonesian IP gives you	What it can cost you
✅ Gojek, Grab and QRIS work properly	⚠️ Netflix shows the Indonesian catalogue, not yours
✅ Tokopedia, Traveloka and local booking sites work	⚠️ Some home streaming services geo-block you
✅ Local prices on apps that vary by country	⚠️ Your bank may flag a login from Indonesia
✅ Indonesian customer service lines connect	⚠️ Some government or work portals block foreign IPs

How to get both

This is easier than it sounds, and it is what we tell customers in the shop.

• Keep your home line installed. Your phone holds both. Switch data to your home line over the villa wifi when you need to log into your bank, then switch back.
• Tell your bank you are travelling before you fly. Thirty seconds in their app. Worth doing regardless of which eSIM you buy.
• Use a VPN for streaming if your home catalogue matters to you.

Airalo has the same issue in reverse. As a roaming eSIM it does not give you an Indonesian number, so the Indonesian half of that list will not work for you at all.

What Happens If It Does Not Work?

This is the question everyone has and nobody asks out loud, especially when buying from a company they have never heard of. So here it is straight, both policies side by side.

	Airalo	Balitel
Change your mind, never used it	14 days — and it ends the moment you activate	30 days, unactivated
Installed but not switched on	Counts as unused	Still fully refundable — just delete it
Something is broken	Request within 30 days of purchase	We fix it, replace it, or refund it
Can they refuse if they fix it?	Yes — if resolved within 10 days of your notice	We would rather fix it than refund it too
Partly used the data	Only the unused portion is refunded	❌ Not refundable once activated
Store credit option	✅ Airmoney, instant	❌ We refund cash only
Cash back to your card	7–10 business days, up to 30 depending on bank	Up to 10 business days
How you ask	App button, email or chat	WhatsApp or email

Two honest points, one each way.

Our change-of-mind window is more than twice as long — 30 days against their 14. If you buy early and your trip moves, that matters.

But Airalo's instant Airmoney credit is genuinely better than anything we offer for the "I bought the wrong plan" case. It is store credit rather than cash, so it is not the same as a refund, but it solves the problem in seconds.

A refund means your holiday already went wrong

Here is the part that matters more than any policy table.

Getting your money back does not get your evening back. If your data dies on the way to Uluwatu, you do not want a refund button and a 10-day wait. You want somebody to fix it in the next ten minutes.

When something breaks in Bali	Airalo	Balitel
Who you contact	In-app chat or email	WhatsApp, a real person
Where they are	Singapore — AirGSM Pte Ltd	Kuta, on the same island as you
What hours	24/7, but from another country	8:00 AM – 2:00 AM Bali time
Can they see the network you are on	No	Yes — we are on it too
Can you walk in	❌ No shop in Indonesia	✅ Five stores in Denpasar, Kuta, Seminyak, Canggu
Can they re-register your IMEI	❌ Not their product	✅ Same day

So Which One Should You Buy?

Your situation	Better pick
Trip of 3 or 4 days, South Bali only	Airalo — the $8 3GB plan
You need under 5GB total	Airalo — we have nothing that small
Bali is one stop on a multi-country trip	Airalo — one plan, many borders
Trip of 5 days or more	Telkomsel — we are 32% to 65% cheaper
You need 10GB or more	Telkomsel — $13 against their $21
Going to Nusa Penida, Amed, or Sidemen	Telkomsel — coverage, not price
Island hopping to Lombok, Flores, or Komodo	Telkomsel
Need a new Grab or Gojek account	Telkomsel — you need the +62 number
Need SMS codes for payments or banking	Telkomsel
Working off a laptop all day	Telkomsel — no daily cap to hit
Worried about getting stuck with no help	Telkomsel — WhatsApp and a real shop in Bali
You expect one very heavy data day	Telkomsel — no daily cap to hit

Frequently Asked Questions

Which is the largest mobile operator in Indonesia?

Telkomsel, with about 157.6 million subscribers as of Q3 2025. Indosat Ooredoo Hutchison is second with roughly 93.7 million and XLSmart third with about 73 million. Telkomsel is majority owned by Telkom Indonesia, the state telecoms company, with Singtel holding 30.1%. Telkomsel covers over 97% of Indonesia's population against about 90% for Indosat, and at the 2026 Ookla Speedtest Awards it won five categories including Best Mobile Coverage.

Is Indosat the same as Telkomsel?

No. They are competing operators. Indosat Ooredoo Hutchison is Indonesia's second largest network with about 93.7 million subscribers, while Telkomsel is the largest with about 157.6 million. In South Bali both perform well and most travellers would not notice a difference. Outside the main tourist corridor, in places like Nusa Penida, Amed, Sidemen, the Gili Islands and eastern Indonesia, Telkomsel's wider coverage becomes the deciding factor.

What is the cap on Airalo's unlimited plan?

3GB per day. After you use 3GB within a day, Airalo throttles your speed to 1 Mbps for the rest of that day. Crucially, the allowance does not reset at midnight — Airalo's fair use policy states it resets every 24 hours counted from the time you activated your eSIM. So if you activated at 6pm, your day runs 6pm to 6pm. Airalo publishes all of this openly, which makes them the most transparent of the major unlimited sellers.

When does Airalo's daily data allowance reset?

Every 24 hours from the moment you activated the eSIM, not at midnight. This is stated in Airalo's own fair use policy. It matters because if you activate in the evening and use your 3GB the following morning, you will be throttled to 1 Mbps for the whole of the following evening rather than recovering at midnight.

Does Airalo limit hotspot or tethering?

No. Airalo's fair use policy states there is no limit on tethering or on the number of devices you connect. This puts Airalo alongside Ubigi and a local Telkomsel plan, all of which allow unrestricted hotspot. Holafly is the exception, capping tethering at roughly 500 MB to 1 GB per day. Note that on an Airalo unlimited plan the 3GB daily cap still covers phone and tethered devices together.

Which network does Airalo use in Indonesia?

Indosat and Tri, branded 3SinyalKuatHemat (Hutchison), both with 5G. Airalo lists these two on the Networks screen in their own app. Airalo does not use Telkomsel in Indonesia. Because Tri and Indosat merged in 2022 to form Indosat Ooredoo Hutchison, these are one operator group rather than two independent fallbacks, and it is Indonesia's second largest network rather than its largest.

Is Airalo good for Bali?

For short trips in South Bali, yes. Airalo's small plans start at USD $4.50 for 1GB and their app is excellent. For trips of five days or more it becomes expensive — their 10GB over 30 days is $21 against $13 for a local Telkomsel plan from an authorized retailer. Airalo also runs on Indosat rather than Telkomsel, which matters once you leave the main tourist corridor for Nusa Penida, Amed, or the outer islands.

Is Airalo cheaper than a local Telkomsel eSIM in Bali?

Only below about $12. Airalo's 1GB, 3GB and 5GB short plans are cheaper than anything Balitel sells, and their 3-day unlimited at $11 beats Balitel's $13. Above that Balitel is cheaper on every comparable plan, by 32% to 65%. The crossover is roughly 3.5 days.

Does Airalo have a daily data limit?

On unlimited plans, yes — 3GB per day, then 1 Mbps until the allowance resets 24 hours after activation. Airalo's fixed-data plans have no daily limit; you use the data at whatever pace you like until it runs out or the plan expires.

Can Airalo receive Grab or Gojek OTP codes?

No. Airalo is data only with no Indonesian +62 number, so SMS verification codes cannot reach you. You cannot create a new Grab or Gojek account on an Airalo eSIM. A local Telkomsel line from an authorized retailer does include an Indonesian number, which is what makes those codes arrive.

What is Airalo's refund policy?

Airalo allows consumers to withdraw from a purchase within 14 days, but that right ends as soon as the eSIM is activated. Refund requests for a service problem must be made within 30 days of purchase, and Airalo is not obliged to refund if they resolve the issue within 10 days of being told. Where data has been partly used, only the unused portion is refunded. Refunds to Airalo's Airmoney store credit are instant, while refunds to the original payment method take 7 to 10 business days. For comparison, Balitel allows 30 days on unactivated eSIMs.

Will Netflix work on an Indonesian eSIM?

Netflix will work, but it will show you the Indonesian catalogue rather than your home one, because a local Telkomsel line gives you an Indonesian IP address. Some other home streaming services may geo-block you entirely. If your home catalogue matters, use a VPN, or switch your phone back to your home line over wifi. This is the trade-off for getting an Indonesian IP, which is also what makes Gojek, Grab, QRIS and local booking sites work properly.

Will my banking app work on an Indonesian eSIM?

Usually, but your bank may flag a login coming from an Indonesian IP address as suspicious. Tell your bank you are travelling before you fly, which takes about thirty seconds in most banking apps and is worth doing whichever eSIM you buy. You can also keep your home line installed and switch data back to it over wifi when you need to log in.

Can I get a refund on a Balitel eSIM?

Yes. Unactivated eSIMs are fully refundable within 30 days of purchase, including ones you have installed but not switched on, because those can simply be deleted. Once the eSIM is activated and your IMEI is registered, the Indonesian number has been issued to you and cannot be reused, so it is non-refundable except in the case of a technical fault we cannot resolve. Refunds go back to your original payment method within about 10 business days.

What happens if my eSIM does not work in Bali?

Message us on WhatsApp and a real person in Bali will troubleshoot it, usually within minutes. We are available from 8:00 AM to 2:00 AM Bali time and we can re-register your IMEI the same day if that is the problem. If we cannot fix it, we replace it or refund it. You can also visit one of our five physical stores in Denpasar, Kuta, Seminyak or Canggu. App-only providers can only offer a chat window from another country.

How much data do I need for Bali?

About one gigabyte per day for normal use — maps, WhatsApp, photos and some scrolling. So a 10-day trip needs roughly 10GB and a three-week trip roughly 21GB. Double it if you stream video or make long video calls, because one hour of Netflix uses about 3GB, which is three normal days of everything else. When in doubt, go one size up.

Why does a Telkomsel eSIM need my passport?

Because it is a local Indonesian line, not a roaming one. Indonesian law requires every mobile number to be registered against a verified identity — citizens use an ID card, foreign residents use a KITAS, and tourists use a passport. On top of that, Indonesia requires foreign phones to have their IMEI registered before they can use a local network. We complete both for you before you arrive. Roaming eSIMs like Airalo skip this because they never give you an Indonesian number in the first place.

Can I buy a Telkomsel eSIM online before I arrive in Bali?

Yes, from an authorized retailer. Balitel operates both an online store and physical shops in Bali, so you can order before you fly, send your passport and IMEI, and have the eSIM registered and delivered to your WhatsApp before departure. You land already connected rather than queuing at the airport.

What is Balitel?

Balitel is an authorized Telkomsel retailer based in Kuta, Bali, operating under registered Telkomsel outlet 3301071729. It sells official Telkomsel tourist eSIM plans that include a real Indonesian +62 phone number, handles the passport and IMEI registration required by Indonesian law, and sends the eSIM QR code by WhatsApp before travelers arrive. Balitel is part of Diamond Handphone, a Bali mobile retail business trading since 1998 with five stores across Denpasar, Kuta, Seminyak and Canggu.

Is Indosat good enough for Bali?

In South Bali, yes. Kuta, Seminyak, Canggu, and Denpasar are well covered. It becomes a problem in the Ubud valleys, on Nusa Penida, in Amed and Sidemen, on ferries, and anywhere in eastern Indonesia. Telkomsel is the safer choice if you are leaving the tourist corridor.

Is Airalo a trustworthy company?

Yes. Airalo is AirGSM Pte Ltd, registered in Singapore, and is the largest travel eSIM provider in the world. It publishes its network partners, its fair use limits and its tethering policy, and has a well-built app with 24/7 support. The criticisms in this article are about which network it uses in Indonesia and what it charges for larger plans, not about whether the company is legitimate.

Our Honest Summary

Airalo is the biggest travel eSIM company for good reasons. The app is the best in the category, the short plans are cheap, support is 24/7, hotspot is genuinely uncapped, and they publish their fair use limit and their network partners when most rivals publish neither. We used their own openness to argue against them in this article, which is a slightly unfair reward for good behaviour.

Three or four days in Seminyak? Buy Airalo. We mean it.

Past that, two things decide it. From five days onward we are 32% to 65% cheaper, and even Airalo's theoretical best price per gigabyte is 70% higher than our 83GB plan. And Airalo runs on Indosat and Tri — one company, Indonesia's second network, no Telkomsel — which runs out of signal in exactly the places worth travelling to.

If you are staying five days or more, leaving South Bali, or you want Grab and Gojek to work, buy a real Telkomsel line — and since Telkomsel cannot sell you one online, that means an authorized retailer like us.

Airalo prices and the network list were taken from Airalo's own app. The 3GB daily threshold, the 24-hour reset and the tethering policy are quoted from Airalo's published Unlimited Data Plans Fair Use Policy. Refund terms are from Airalo's terms of use. Operator subscriber figures are from published industry data (Telkomsel Q3 2025; Indosat and XLSmart Q4 2025) and award results from Ookla and Opensignal as announced in 2026. All checked 26 August 2026 and subject to change. Correction: an earlier version of this page said the daily allowance resets at midnight. It resets 24 hours after activation. Corrected 26 August 2026.
