Cheapest Indonesia eSIM by plan size (full breakdown)
Prices alone don't tell the full story — a $4.50 plan that expires in 3 days is not "cheap" for a week-long trip. The table below includes validity alongside price so you can compare like for like. Every provider's full plan list, including the unlimited options left out here, is in our Indonesia eSIM price guide.
| Data | Cheapest option | Price (USD) | Validity | Runner-up |
|---|---|---|---|---|
| 1 GB | Travelsim Asia | $3.99 | 7 days | Nomad / Ubigi — $4.00 / 7d |
| 3 GB | Ubigi | $7.00 | 15 days | Travelsim Asia — $7.99 / 15d |
| 5 GB | Travelsim Asia | $10.99 | 30 days | Nomad — $12.00 / 30d |
| 10 GB (30 days) | Ubigi | $16.00 | 30 days | Travelsim Asia — $16.99 / 30d |
| 20 GB | Travelsim Asia | $27.99 | 30 days | Nomad — $33.00 / 45d |
| 50 GB | Travelsim Asia | $36.99 | 30 days | Nomad — $41.00 / 45d |

Cheapest Indonesia eSIM for a 1-week trip
For a standard 7-day trip to Indonesia with regular use — Grab and Gojek rides, WhatsApp, maps, and some social media — 3 GB is typically enough. The cheapest 3 GB option with at least 7 days validity is Ubigi at $7.00 for 15 days, with Travelsim Asia close behind at $7.99 for the same validity window plus Telkomsel access.
| Provider | 3 GB price | Validity |
|---|---|---|
| Ubigi | $7.00 | 15 days |
| Travelsim Asia | $7.99 | 15 days |
| Nomad | $8.00 | 30 days |
| Saily | $8.99 | 30 days |
| Airalo | $8.50 | 7 days |
1-week verdict: Ubigi wins on raw price at $7.00. Travelsim Asia at $7.99 adds Telkomsel access (Indonesia's strongest network for rural and outer-island coverage) for an extra $0.99 — a worthwhile trade if your itinerary goes beyond Bali and Jakarta. Both have 15-day validity, giving you a comfortable buffer. Airalo's 3 GB at $8.50 with only 7-day validity is the worst value at this tier.
Cheapest Indonesia eSIM for a 2-week trip
Two weeks in Indonesia with typical tourist usage — heavy Grab/Gojek, daily WhatsApp, some streaming — lands most travelers in the 5–10 GB range. The cheapest options:
| Provider | Plan | Price | Validity |
|---|---|---|---|
| Travelsim Asia | 5 GB | $10.99 | 30 days |
| Nomad | 5 GB | $12.00 | 30 days |
| Ubigi | 10 GB | $14.00 | 7 days only |
| Ubigi | 10 GB | $16.00 | 30 days |
| Travelsim Asia | 10 GB | $16.99 | 30 days |
| Nomad | 10 GB | $19.00 | 30 days |
Note on Ubigi's $14.00 / 10 GB plan: This is the cheapest 10 GB plan among the providers compared here — but the 7-day validity makes it unsuitable for a 2-week trip. It's genuinely good value for a short, data-heavy stay. For 30-day validity, Ubigi's $16.00 is still cheapest, with Travelsim Asia $0.99 more at $16.99 with the Telkomsel coverage advantage.
Cheapest Indonesia eSIM per GB
If you want to find the absolute best value per gigabyte — regardless of trip length — here's how every major provider compares:
| Plan | Provider | Price | Price per GB | Validity |
|---|---|---|---|---|
| 50 GB | Travelsim Asia | $36.99 | $0.74/GB | 30 days |
| 50 GB | Nomad | $41.00 | $0.82/GB | 45 days |
| 50 GB | Airalo | $49.00 | $0.98/GB | 30 days |
| 25 GB | Ubigi | $28.00 | $1.12/GB | 30 days |
| 20 GB | Travelsim Asia | $27.99 | $1.40/GB | 30 days |
| 10 GB | Ubigi | $14.00 | $1.40/GB | 7 days |
| 10 GB | Ubigi | $16.00 | $1.60/GB | 30 days |
| 10 GB | Travelsim Asia | $16.99 | $1.70/GB | 30 days |
| 5 GB | Travelsim Asia | $10.99 | $2.20/GB | 30 days |
| 3 GB | Ubigi | $7.00 | $2.33/GB | 15 days |
| 1 GB | Travelsim Asia | $3.99 | $3.99/GB | 7 days |
Within a provider's fixed-plan range, larger allowances generally cost less per GB; compare validity too. The jump from 20 GB to 50 GB roughly halves the per-GB rate at Travelsim Asia.
Travelsim Asia's 50 GB / 30-day plan at $0.74/GB is the lowest per-GB rate for any Indonesia eSIM in this comparison. It costs $4.01 less than Nomad's 50 GB / 45-day plan and $12.01 less than Airalo's 50 GB / 30-day plan. For long stays in Bali or multi-island itineraries, this is the lowest unit price in the comparison.
How Indonesia prices compare with Japan
Indonesia is not consistently cheaper than Japan. In the 10 October comparison, Travelsim Asia's Indonesia plans cost more at every matching allowance and validity. Three examples:
- 5 GB for 30 days. Travelsim Asia costs $10.99 for Indonesia and $9.99 for Japan, a $1.00 difference.
- 20 GB for 30 days. Travelsim Asia costs $27.99 for Indonesia and $22.99 for Japan, a $5.00 difference.
- 50 GB for 30 days. Travelsim Asia costs $36.99 for Indonesia and $34.99 for Japan, a $2.00 difference. Compare the same provider, allowance and validity before drawing a country-wide conclusion.
How much data do you actually need in Indonesia?
A week of ordinary use in Indonesia runs 3 to 5 GB. Two weeks runs closer to 10 GB. At the prices above that is $7.99 to $10.99 for a week and $16.99 for a fortnight, which is why the 5 GB and 10 GB tiers are where most of the value sits. If you want that estimate built up app by app rather than assumed, our Indonesia data guide works through what Grab, WhatsApp and Maps actually consume.
Does cheapest mean worst network coverage?
Not always. In Indonesia the network you connect to matters more than almost anywhere else: with thousands of islands and sharp terrain shifts, the wrong network means dead zones outside the major cities. Which provider runs on which Indonesian network, and how each one holds up on the outer islands, is set out in our Indonesia buyer's guide.
Telkomsel is Indonesia's most important network , particularly outside Java and Bali. If your itinerary includes Lombok, Flores, Sumba, Sumatra, Sulawesi, Raja Ampat or any rural area, Telkomsel access materially affects whether you have signal. Travelsim Asia is the only eSIM in this comparison listing all three Indonesian operator groups: Telkomsel, Indosat and XLSmart through XL/Smartfren.
Validity traps: when "cheap" isn't actually cheap
The three most common mistakes when picking an Indonesia eSIM on price alone:
- Airalo's 1 GB / 3-day plan at $4.50. It's not even the cheapest 1 GB plan — Travelsim Asia, Nomad, and Ubigi all sit at $3.99–$4.00 with 7-day validity. Airalo's plan is more expensive and expires faster.
- Ubigi's 10 GB / 7-day plan at $14.00. Genuinely the cheapest 10 GB option among the providers compared here — but it's a 7-day window. For a 10-day trip you'd need two plans, bringing total cost to $28.00. Ubigi's $16.00 / 30-day plan (or Travelsim Asia's $16.99 / 30-day) is the right call for most travelers.
- Holafly is the wrong buy if price is your first filter. It sells unlimited plans only, at roughly $4/day, so a short trip costs several times what a fixed plan covering the same days costs. The full cost comparison is in our Indonesia price guide.
Cheapest Indonesia eSIM with no app required
Airalo, Nomad and Ubigi also offer QR installation outside their apps. Install before travel while you have WiFi.
Travelsim Asia requires no app or account: the eSIM arrives by email, and balance checks and top-ups work through your personal web portal without a login. For travelers who want the cheapest option that's also app-free: Travelsim Asia's 1 GB at $3.99 has the lowest 1 GB price among the providers compared here and includes email installation with no app or account required.
Final verdict: which is the cheapest Indonesia eSIM?
- Cheapest overall for short trips (1 GB): Travelsim Asia — $3.99 for 1 GB / 7 days. The lowest 1 GB price among the plans compared here, with joint-longest seven-day validity at this size.
- Cheapest for light trips (3 GB): Ubigi — $7.00 / 15 days. Travelsim Asia at $7.99 / 15 days is $0.99 more but adds Telkomsel coverage.
- Cheapest for standard trips (5 GB): Travelsim Asia — $10.99 / 30 days. Cheapest 5 GB plan among the providers compared here and the only one under $12 with Telkomsel access.
- Cheapest 10 GB: Ubigi at $16.00 / 30 days (or $14.00 / 7 days for short trips). Travelsim Asia's $16.99 / 30 days is $0.99 more but gains Telkomsel coverage.
- Cheapest 20 GB and 50 GB: Travelsim Asia — $27.99 and $36.99 respectively, both for 30 days. The 50 GB plan delivers the lowest per-GB rate among these Indonesia plans at $0.74/GB.
- Price watch: Holafly at ~$4/day and Airalo's 1 GB / 3-day plan for trips longer than 3 days. Network watch: Ubigi lists Indosat alone and Saily lists Telkomsel on its current Indonesia page. Airalo lists Telkomsel, but Travelsim Asia costs less at every matching fixed-data size.
