eSIM Bali & Indonesia 2026: Provider Comparison and Costs for 7, 14 and 30 Days

Four providers published their Indonesia plans in a way we could actually read: Simbye, aloSIM, Airalo and Holafly. Prices run from €1.95 for 1 GB (Simbye, blog post of 3 June 2026) up to $76.50 for 30 days with no data cap (Holafly, as of 10 October 2026).

"Not stated" under hotspot just means the page we read didn't say. It doesn't mean tethering is blocked.

Simbye: cheapest way in, with a catch in the date

According to Simbye's blog post of 3 June 2026, Simbye leads this comparison at €1.95 for 1 GB and 7 days. The bigger plans are cheap too, all valid for 30 days: 5 GB for €6.95, 10 GB for €11.95, 20 GB for €19.95. Unlimited costs €19.95 for 7 days or €33.95 for 15 days.

The catch is the date. Those figures come from the blog post, not the shop, because Simbye's Indonesia shop page wasn't available on 10 October 2026. Four-month-old prices might still hold. Might not.

Simbye lists Telkomsel and Indosat as its networks. For island-hopping, Telkomsel on that list matters; more on that in the coverage section.

aloSIM: fixed GB plans, priced in dollars

On its Indonesia page, aloSIM sells everything from 1 GB for 7 days ($4.50) up to 20 GB for 30 days ($35.00), all as of 10 October 2026. In between you'll find 2 GB for 15 days at $7.00, 5 GB at $14.00 and 10 GB at $22.00, the last two also valid for 30 days. aloSIM names three networks: Indosat Ooredoo Hutchison, Telkomsel and Tri.

The price table on that page is headed "Unlimited", yet every row underneath has a fixed data cap. Go by the GB figure, not the heading.

Airalo: only the unlimited plans checked

On Airalo, only the unlimited tab loaded for us on 10 October 2026. Three days cost €10.50 there, 15 days €44.00. That's why Airalo's fixed-GB plans are missing here; we don't copy prices from second-hand sources.

On networks, Airalo names 3SinyalKuat, which is the Tri network, plus two more without naming them. In Canggu that probably won't matter. On Flores it might.

Holafly: unlimited, with strings attached

Holafly only sells unlimited plans for Indonesia, starting at $11.90 for 3 days (as of 10 October 2026), and lists XL and Telkomsel as its networks. Two limits sit on that same page: hotspot sharing is capped at 1 GB a day, and a fair usage policy can slow your speed for up to a day. So unlimited means unlimited volume here, not unlimited speed.

Who's missing, and why

Saily, Nomad, Yesim, Ubigi and eSIM FOX all sell Indonesia plans too. On 10 October 2026, though, their price pages either wouldn't load or didn't show plan data. We don't copy prices from search snippets: one snippet gave Saily the same dollar price for 5 GB in one place and for 10 GB in another. If one of these providers is on your shortlist, check its price on its own page.

With a fixed data plan, a week starts at €1.95 (Simbye, blog post of 3 June 2026) and a month with 20 GB at €19.95 (also Simbye). Thirty days of unlimited data cost €63.00 with Airalo (as of 10 October 2026). Per GB, roaming sits above the fixed Simbye plans in all three scenarios, both in euros, so no conversion is needed. Unlimited plans have no per-GB price, so they can't be compared that way.

The math follows the same method as our eSIM vs. roaming breakdown for two weeks in the USA: published price, no discount codes, no currency conversion. How much data you need, we can't tell you without knowing how you travel. Our guide How Much Data Do I Need for Travel? walks you through working it out. So we're sticking to the plan sizes providers actually sell.

Table sources: Simbye per its blog post of 3 June 2026. aloSIM, Airalo, Holafly, Vodafone and O2 per their own pages on 10 October 2026. Telkomsel: price and data per a Holafly guide dated 20 August 2026, validity per Tempo of 19 April 2024. The Vodafone figures for 14 and 30 days are our own multiplication of the weekly price. Plans valid for 30 days also cover shorter trips; you just use part of the validity.

One week in Bali

A week in Canggu or Ubud is almost boring, cost-wise. If 1 GB is enough, you'll pay €1.95 at Simbye (blog post of 3 June 2026) or $4.50 at aloSIM (as of 10 October 2026). More breathing room comes with 5 GB for €6.95, again Simbye, but then with 30 days of validity.

Seven days of unlimited data run from €19.95 (Simbye blog, 3 June 2026) to $27.50 (Holafly, as of 10 October 2026). You only need that if you watch or upload a lot of video. And if you plan to tether a laptop, Holafly of all providers is the wrong pick, given its 1 GB daily hotspot cap.

Two weeks with 10 GB

Let's take two weeks and 10 GB as the example, without claiming that fits everyone. Simbye charges €11.95 for that (blog post of 3 June 2026), aloSIM $22.00 (as of 10 October 2026), both valid for 30 days. On a German Vodafone plan you'd need two ReisePaket World weekly packs at €34.99 each (as of 10 October 2026), which works out to €69.98, and you'd still only get 8 GB.

Per GB, that's €8.75 at Vodafone (€34.99 divided by 4 GB) against just under €1.20 at Simbye (€11.95 divided by 10 GB), a gap of a good €7.50 per GB. O2 is cheaper than Vodafone at €14.99 a month (as of 10 October 2026) but only gives you 2 GB. Whether that covers two weeks is something the data guide linked above can help you work out.

A month or longer

At 30 days the picture shifts a bit. 20 GB costs €19.95 at Simbye (blog post of 3 June 2026) and $35.00 at aloSIM (as of 10 October 2026). Unlimited costs €63.00 at Airalo and $76.50 at Holafly, also as of 10 October 2026. Suddenly the Telkomsel tourist SIM with 25 GB for 30 days (per a Holafly guide dated 20 August 2026) starts to look interesting. More on that in a moment.

If Bali is just one stop, say with a Singapore layover or onward travel to Thailand, a single-country eSIM may stop making sense. For longer trips across several countries, see eSIM for Multiple Countries: The Nomad Strategy.

If you're looking for a SIM card for Bali, you have two basic routes: a travel eSIM or Telkomsel's physical tourist SIM. The tourist SIM gives you a lot of data: 25 GB plus 25 minutes of local calls for Rp 150,000, according to a Holafly guide dated 20 August 2026. The 30 days of validity for the 25 GB come from Tempo, 19 April 2024. The trade-off is time at a counter, a physical SIM slot, and registration with your passport and a face scan.

Telkomsel's own FAQ on the Tourist Prepaid Card describes it as a starter pack you order online and pick up after you arrive in Indonesia. It doesn't list price or data, though; the figures above come from the Holafly guide.

Where you pick it up seems to change. According to Nomad's guide, pickup is currently only possible in Bali and in Mandalika on Lombok, and the plan only comes as a physical card. That guide isn't dated, and Tempo listed other pickup points in April 2024, Yogyakarta among them. Before you fly, check Telkomsel's own page.

What to bring, per Nomad and Tempo: your passport, your phone's IMEI and an unlocked phone. Since 1 July 2026, every new local SIM also requires the face scan, which bali.live says means your original passport plus a valid entry stamp or visa. Whether the tourist plan can be extended, we couldn't confirm in the sources we read; ask Telkomsel.

We're deliberately not converting the rupiah prices. Sources use different exchange rates, and a dollar or euro figure without a dated rate would be a guess. If you want to compare, check your banking app on the day. The same Holafly guide of 20 August 2026 also lists Indosat options, such as "Travel On 30 GB" for Rp 100,000 with 30 days of validity.

Usually not worth it. Vodafone Germany charges €34.99 per week for 4 GB on its ReisePaket World, or €9.99 per day for 500 MB, while O2 Germany offers 2 GB for €14.99 a month with Roaming Plus World (both as of 10 October 2026). The upside: nothing to install.

Vodafone also has a ReisePaket Data with 3 GB for €29.99 per week in country zone 1 (as of 10 October 2026), and its page lists Indonesia explicitly. O2's page didn't say which contracts can book the option, so that's one to check in your own plan.

Telekom is the odd one out. Its roaming page mentions passes from €5.95 one-off (as of 10 October 2026), but the Indonesia prices sit inside a price tool we couldn't read. So we're not quoting a number for Indonesia. If you're with Telekom, look it up there yourself.

One trap is spelled out on Vodafone's own page: the ReisePakete activate automatically when you enter the destination country. If you use a travel eSIM and keep your German SIM active alongside it, you should turn off data roaming on the German line. Otherwise you might end up paying twice without noticing.

On a US, UK or Australian plan? We didn't collect your carrier's Indonesia rates, so the German numbers above won't apply to you. The method still does: divide your carrier's daily or weekly pass by the GB it includes, and compare with the eSIM rows, exactly like the USA breakdown linked earlier.

The rules changed in 2026, so here's the short version (as of 10 October 2026).

• Local SIM or eSIM from Telkomsel, Indosat or XL: since 1 July 2026, every newly issued card comes with registration by passport and face scan. According to Komdigi Director General Edwin Hidayat Abdullah, it takes under a minute on average (Tempo, press conference of 29 May 2026).

• Travel eSIM from a foreign provider such as Airalo or Holafly: per mybestsim.com (an eSIM comparison site, page undated) it works as a roaming data profile and falls outside that registration.

• IMEI: a separate, older system. If you use a local card, customs (DJBC, via DDTC News of 4 April 2024) says the temporary 90-day IMEI activation happens at the mobile operator's counter, not at customs.

All the details and exceptions are in our post on Indonesia's new SIM registration rules. We couldn't open a primary page from Komdigi or customs; the statements rest on the media named above. A quick look at Komdigi and Bea Cukai before you leave doesn't hurt.

The travel blog Unusual Nomad calls south Bali the easy part. On Nusa Penida, the Gilis, Lombok and Flores, the Indonesian network behind your eSIM plays a bigger part. For the outer islands, the provider esim-now describes Telkomsel as the only network with dependable reach.

The clearest account is the travel blog Unusual Nomad, in a comparison dated 21 September 2026. It compares Nomad, Airalo and Yesim across Bali, Nusa Penida, Lembongan, Lombok and the Gilis, and concludes that a plan can be excellent in Canggu or Seminyak and much less convincing in the interior or on the next island. Those are the blog's experiences, not ours.

The Flores and Rinjani details come from the esim-now.com coverage guide, updated 9 October 2026. Keep in mind esim-now is an eSIM seller itself, which also applies to its Telkomsel statement above. The same guide says eSIMs that run only on Indosat or XL can struggle at rice terraces, dive sites and between islands.

So is Telkomsel simply the best network? Not that simple. The summary of Opensignal's July 2026 Indonesia report puts XL ahead on speed and 5G; we couldn't open the page itself, so the summary is all we know. The December 2025 report already noted, per its summary, that XLSmart had expanded its 4G coverage in eastern Indonesia and across Bali. Our read of the sources: XL is catching up on speed, while reach on remote islands remains Telkomsel's argument, as esim-now describes it.

For your choice, that means: Simbye, aloSIM and Holafly list Telkomsel among their networks; Airalo names Tri plus two unnamed ones. That's no proof of better reception, only a sign that Telkomsel is in the mix, according to the provider.

For Java, meaning Jakarta, Yogyakarta or Bromo, we didn't find a dated coverage report aimed at travelers. We'd rather name that gap than fill it with guesses.

The least stressful way is to install the eSIM at home on Wi-Fi and only switch on its data connection after you land. When validity starts is up to each provider; the rule is in the plan details. Your home SIM can stay active alongside it, for banking texts for instance, as long as data roaming on that line is off. New to all this? How Does an eSIM Work Abroad? covers the basics from QR code to dual SIM.

There's no recommendation here without a catch, so every profile also says who it doesn't suit.

One week in south Bali with normal browsing? A small GB plan from Simbye or aloSIM does it, depending on whether you'd rather pay in euros or dollars. Not for you if you upload video every day.

Two or three weeks of island-hopping to Nusa Penida, the Gilis or Lombok? Then a 10 or 20 GB plan makes sense, depending on your usage, from a provider that lists Telkomsel among its networks, which per the providers' own information means Simbye or aloSIM. If you stream shows every evening, run the numbers more carefully (the data guide above helps).

Remote work with a laptop is where unlimited makes sense. Airalo at €63.00 for 30 days or Holafly at $76.50 (both as of 10 October 2026) are the options, with the caveat that Holafly caps hotspot use at 1 GB a day and Airalo's page said nothing on hotspot. If your laptop gets online through your phone, Holafly is a dealbreaker. And with Airalo, the network question for Flores stays open.

• Long stay, tight budget, time to spare at a counter: the Telkomsel tourist SIM. Not for phones without a SIM slot, and not for anyone who can't spare time at the counter on arrival day.

• Barely any data, mostly hotel Wi-Fi, on a German O2 contract: Roaming Plus World with 2 GB for €14.99 a month (as of 10 October 2026) is convenient, if your plan allows it. For anything more, too expensive.

The last check before you pay: the plan page has a line naming the network. If it says Telkomsel, that's the safer bet for the outer islands according to esim-now. If it names another network or none, ask the provider first.
