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
5 GB Travelsim Asia $10.99 30 days Nomad — $12.00 / 30d
10 GB 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 $34.99 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 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.

Final verdict: which is the cheapest Indonesia eSIM?

  • Cheapest overall for short trips (1 GB): Travelsim Asia — $3.99 for 1 GB / 7 days. Lowest 1 GB price in the Indonesia eSIM market with the longest validity at this tier.
  • 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 in the Indonesia market 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 $34.99 respectively, both for 30 days. The 50 GB plan delivers Indonesia's lowest per-GB rate at $0.70/GB.
  • 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).

Cheapest Indonesia eSIM — Frequently Asked Questions

What is the cheapest Indonesia eSIM in 2026?

The cheapest 1 GB Indonesia eSIM is Travelsim Asia at $3.99 for 7 days. The cheapest 5 GB is Travelsim Asia at $10.99 / 30 days, and the cheapest 50 GB is Travelsim Asia at $34.99 / 30 days. Ubigi is cheapest at 3 GB ($7.00) and 10 GB / 30 days ($16.00).

Which Indonesia eSIM has the lowest price per GB?

Travelsim Asia's 50 GB / 30-day plan at $0.70 per GB is the lowest per-GB rate of any Indonesia eSIM in 2026. It beats Nomad's 50 GB ($0.82/GB) by $6 absolute and Airalo's ($0.98/GB) by $14 for the same 30-day window.

What is the cheapest Indonesia eSIM for a one-week trip?

For a 7-day trip, 3 GB is typically enough. Ubigi is cheapest at $7.00 for 15 days; Travelsim Asia is $7.99 for 15 days and adds Telkomsel coverage. Airalo's 3 GB at $8.50 with only 7-day validity is the worst value at this tier.

Is the cheapest Indonesia eSIM also the best?

Not always. Ubigi is cheapest at 3 GB and 10 GB but runs on Indosat and XL, with no Telkomsel access — fine for Bali and Jakarta, weaker on the outer islands. Travelsim Asia is marginally more expensive at those tiers but adds Telkomsel coverage for travel beyond Java and Bali.

Holafly charges roughly $3.90 per day with no fixed-data option. A 7-day Holafly plan costs $27.30 — over 2.5 times the price of a Travelsim Asia 5 GB plan ($10.99) that covers the same trip. Holafly only makes sense for travelers who specifically need uncapped unlimited data.
