What Is the Cheapest Reliable eSIM for Bali?
The cheapest eSIM for Bali depends on how much data you need and how long you stay, and the lowest advertised price is rarely the best value. A $4.50 plan sounds cheap until you realise how little data it holds, while a plan that costs more upfront can work out cheaper per GB. "Reliable" matters just as much, so we compare price, data, validity, network, and restrictions side by side.
This guide compares BaliSIM, Airalo, and Holafly using each provider's own pages. BaliSIM publishes this article, so we only report what each provider states, and we don't claim any of them is the cheapest or most reliable for everyone.
- Lowest upfront price: Airalo's Indonesia page lists plans from $4.50, for a small allowance.
- Lowest price per GB we could confirm: BaliSIM's XL 18 GB plan ($13.14, about $0.73 per GB) and its Telkomsel Indonesia 38 GB plan ($27.96, about $0.74 per GB), at current page prices.
- Unlimited data: price per day is the number to compare, and fair-use limits can apply.
Bali eSIM Price Comparison (Checked November 1, 2026)
The table lists plans whose prices we could confirm on official pages. Price per GB is simply the price divided by the data allowance. Unlimited plans are compared per day instead.
| Plan | Network | Data and validity | Price | Value | Number, hotspot, registration |
|---|---|---|---|---|---|
| BaliSIM Telkomsel, Bali Visitor | Telkomsel | 13 GB (smallest). Described for Bali and Lombok. Data valid for 30 days from arrival date | $14.56 (list price $16.25) | ~$1.12 per GB | +62 number and hotspot included. Passport and IMEI registration |
| BaliSIM XL, Bali Visitor | XL | 18 GB (smallest). Data 30 days, IMEI active 90 days | $13.14 (list price $15.22) | ~$0.73 per GB | +62 number, hotspot, and 5 call minutes included. Passport and IMEI registration |
| BaliSIM Telkomsel, Indonesia (Nationwide) | Telkomsel | 38 GB (smallest). Data 28 days, IMEI active 30 days | $27.96 (list price $35.44) | ~$0.74 per GB | +62 number, hotspot, and 120 call minutes included. Passport and IMEI registration |
| Airalo Indonesia, smallest plan | Indosat listed as primary, plus two others | Fixed-data plans from $4.50. Sizes and validity not confirmed on the page we reviewed | From $4.50 | Per GB not verified | Data-only per Airalo's guide. Airalo says no registration queue |
| Airalo Indonesia, unlimited | Indosat listed as primary, plus two others | 7 days; 30 days | $27; $69 | ~$3.86 per day; ~$2.30 per day | Data-only. Fair-use limits may apply |

BaliSIM prices include the discount shown on each page, so they can change. BaliSIM's larger sizes (for example 20 to 83 GB on the Telkomsel Bali plan and up to 403 GB on the XL plan) have their own prices on the product pages, and we haven't listed them here. We couldn't confirm Airalo's fixed-data price list on its official page, so we show no per-GB figure for it. Check each page before buying.
Cheapest eSIM Options for Different Travel Needs
What Affects eSIM Price and Reliability?
- Data allowance and validity. A cheap plan that expires early, or runs out in three days, isn't cheap.
- Network. The plan borrows a local operator's network. Telkomsel, XL, and Indosat differ by location, so check which one your plan uses.
- Included extras. A local number, call minutes, and hotspot all carry value. Compare plans with the same extras.
- Fair-use limits. Unlimited plans may slow down after heavy daily use, and hotspot can be capped.
- Registration and top-up rules. These affect convenience and what happens if you run out.
- Promotions. On-page discounts change. Compare list prices as well as current prices.
Reliability can't be read from a price tag. These are the signals each provider publishes. They aren't a ranking, and the review platforms and volumes aren't comparable.
| Provider | Support channels | Other published signals |
|---|---|---|
| BaliSIM | WhatsApp +62 813-3977-4203 and email; troubleshooting guide | Trustpilot showed 259 reviews and a 4.7 TrustScore on October 29, 2026. Trustpilot says it doesn't verify review content |
| Airalo | States 24/7 support, including WhatsApp chat | Its page shows app ratings of 4.7 (iOS) and 4.6 (Android) |
| Holafly | States 24/7 chat support | Offers refunds, including for connection issues, with conditions. Its page displays 116,811 Trustpilot reviews |

Frequently Asked Questions
What is the cheapest eSIM for Bali?
It depends on your data and days. Airalo's Indonesia page lists plans from $4.50, but for a small allowance. Among plans whose prices we could confirm, BaliSIM's XL 18 GB ($13.14) and Telkomsel Indonesia 38 GB ($27.96) came to about $0.73 and $0.74 per GB. Compare the same data and validity before you decide.
Is the cheapest Bali eSIM reliable?
Not automatically. Price says nothing about signal, support, or refunds. Check which network the plan uses, how you can reach support, and whether a refund route exists. No eSIM, cheap or expensive, can guarantee coverage in every location, particularly on remote islands, in mountains, or at sea.
How do I compare Bali eSIM prices fairly?
Compare the same data allowance over the same number of days, then divide the price by the GB to get price per GB. For unlimited plans, divide by the number of days instead. Then add up what's included, such as a local number, calls, and hotspot, and check any registration or top-up rules.
Is an unlimited eSIM cheaper for Bali?
Usually only for heavy users or longer stays. Unlimited plans we reviewed cost about $2.30 to $2.55 per day over 30 days, and more for short terms. They can carry fair-use speed limits, and Holafly caps hotspot at 1 GB per day. A fixed plan can cost less if you don't use much data.
How much data do I need to avoid overpaying?
Light use such as maps and messaging needs far less than heavy use such as streaming or tethering a laptop. Estimate your own usage first, since paying for unused gigabytes is the most common way to overspend. BaliSIM's data usage calculator can help, and you should match the plan's validity to your trip.
Do cheap Bali eSIMs include a local number?
Often not. Airalo's and Holafly's Indonesia plans are described as data-only, so they have no Indonesian number or regular calls. BaliSIM's product pages list a +62 number on the plans we reviewed. If an app needs a local number to verify your account, compare plans with that feature.
Do Bali eSIMs require registration?
It depends on the provider. BaliSIM's product pages require passport and IMEI details through an online form, ideally before arrival. Airalo says its Indonesia eSIM has no registration queue, and Holafly's page describes no registration step. Registration takes time, so weigh it alongside the price.
Are the discounted prices permanent?
No. BaliSIM's product pages show a current price with a crossed-out list price, and promotions change. For example, the Telkomsel Bali 13 GB plan showed $14.56 against a $16.25 list price on our check date. Compare both numbers, and confirm the price at checkout before you buy.
Is BaliSIM the cheapest eSIM for Bali?
Not necessarily. Airalo lists a lower entry price for a small plan, and the cheapest option changes with data size, validity, and promotions. BaliSIM's strengths in this comparison are included extras such as a +62 number and hotspot, plus per-GB pricing on larger plans. Compare the exact plan you need.
