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.
| 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 |

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 | Networks |
|---|---|---|---|
| Ubigi | $7.00 | 15 days | Indosat + XL |
| Travelsim Asia | $7.99 | 15 days | Telkomsel + XL |
| Nomad | $8.00 | 30 days | Telkomsel + Smartfren |
| Saily | $8.99 | 30 days | Undisclosed |
| Airalo | $8.50 | 7 days | 3 + Indosat |
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 | Networks |
|---|---|---|---|---|
| Travelsim Asia | 5 GB | $10.99 | 30 days | Telkomsel + XL |
| Nomad | 5 GB | $12.00 | 30 days | Telkomsel + Smartfren |
| Ubigi | 10 GB | $14.00 | 7 days only | Indosat + XL |
| Ubigi | 10 GB | $16.00 | 30 days | Indosat + XL |
| Travelsim Asia | 10 GB | $16.99 | 30 days | Telkomsel + XL |
| Nomad | 10 GB | $19.00 | 30 days | Telkomsel + Smartfren |
Note on Ubigi's $14.00 / 10 GB plan: This is the cheapest 10 GB plan in the market — 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 | $34.99 | $0.70/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 |
Larger plans always cost less per GB. 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 $0.70/GB is the lowest per-GB rate for any Indonesia eSIM in this comparison. It beats Nomad's 50 GB by $6 absolute and Airalo's by $14, despite all three covering the same 30–45 day windows. For long stays in Bali or multi-island itineraries, this is the value floor.
Why Indonesia eSIMs are cheaper than Japan
Indonesia eSIMs are consistently priced $1–3 lower than equivalent plans for Japan or South Korea at the same data tiers. Three reasons:
- Lower wholesale carrier costs. Indonesia's mobile networks — Telkomsel, XL, Indosat, 3, Smartfren — operate in a high-volume, lower-ARPU market. Wholesale data rates for international eSIM providers are correspondingly lower than Japan's high-cost carriers.
- Higher tourist competition. Indonesia (especially Bali) has dozens of eSIM providers competing for tourist data spend. Price pressure is intense, particularly at the 1–10 GB tiers.
- Mature local prepaid SIM market. Indonesia's local SIM cards from Telkomsel, XL, and Indosat are genuinely cheap (IDR 50,000–200,000 / ~$3–13 for tourist plans). eSIM providers have to price competitively against the physical SIM alternative.
How much data do you actually need in Indonesia?
Indonesia is moderately data-hungry. Three things drive most of your usage: Grab and Gojek (constant location updates and in-app maps), Google Maps for inter-island navigation, and WhatsApp for everything — from villa hosts and tour guides to scooter rentals and restaurants.
| Usage profile | Per day | 7 days | 14 days | Recommended plan |
|---|---|---|---|---|
| Grab, maps, WhatsApp, browsing | 300–600 MB | 2–4 GB | 4–8 GB | 3–5 GB |
| + social media, photos | 800 MB–1.5 GB | 5–10 GB | 10–20 GB | 10 GB |
| + video calls, streaming, hotspot | 2–4 GB | 14–28 GB | 28–56 GB | 20–50 GB |
Most tourists fall in row 1 or 2. Villa, café, and hotel WiFi in Bali is generally reliable — supplement your eSIM for heavier tasks.
Does cheapest mean worst network coverage?
Not always — but in Indonesia, the network you connect to matters more than almost anywhere else. With thousands of islands and dramatic terrain shifts, the wrong network can mean dead zones outside major cities:
| Provider | Networks | Rural / island coverage | 5G |
|---|---|---|---|
| Travelsim Asia | Telkomsel + XL Axiata | Excellent | Yes |
| Holafly | Telkomsel + XL Axiata | Excellent | Yes |
| Nomad | Telkomsel + Smartfren | Good | Partial |
| Ubigi | Indosat + XL (XLSmart) | Moderate | Partial |
| Airalo | 3 (Hutchison) + Indosat | Moderate | Partial |
| Saily | Not publicly disclosed | Unverified | Partial |
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, Holafly, and Nomad are the only providers in this comparison with Telkomsel access. Travelsim Asia and Holafly add XL Axiata for strong urban backup; Nomad pairs with Smartfren (weaker as a secondary). Airalo and Ubigi do not include Telkomsel — fine for Jakarta and Bali, risky for outer islands.
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 in the market — 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 — avoid entirely for cost-conscious travelers. At $3.90/day for short trips, a 7-day Holafly plan costs $27.30 — over 2.5x what a Travelsim Asia 5 GB fixed plan costs for the same trip ($10.99). Holafly only makes sense if you specifically need unlimited data and aren't willing to track GB usage.
Cheapest Indonesia eSIM with no app required
Most Indonesia eSIM providers require downloading an app and creating an account before installing the eSIM. If you're buying last-minute at Bali Ngurah Rai or Jakarta Soekarno-Hatta with no data connection, this creates a catch-22.
Travelsim Asia is the only provider in this comparison that requires no app and no account — the eSIM is delivered by email and installs in any browser. For travelers who want the cheapest option that's also app-free: Travelsim Asia's 1 GB at $3.99 is both the lowest 1 GB price in the market and the only one requiring no account or app to install.

- Avoid on price: Holafly at $3.90/day; Airalo's 1 GB / 3-day plan for any trip longer than 3 days; Saily, Airalo, and Ubigi for travel outside Java/Bali (none connect to Telkomsel).
