Indonesia eSIM: Travelsim Asia vs Airalo — Price, Networks & Honest Review (2026)
Last updated: May 16, 2026
Travelsim Asia and Airalo are two popular eSIM providers for Indonesia. Both work, both are legitimate, and both will get you online at Bali Ngurah Rai or Jakarta Soekarno-Hatta without standing in a SIM queue. But they're not identical — and depending on how you travel, one might suit you noticeably better than the other.
This is a straightforward comparison. We run Travelsim Asia, so we're not neutral — but where Airalo is the better pick, we'll say so.
Price comparison
Here's a side-by-side of the closest matching plans. All prices in USD.
Short trips (1–3 GB)
If you're visiting Indonesia for a week or less and mostly using Grab, WhatsApp, and Google Maps.
| Data | Travelsim Asia | Airalo | Verdict |
|---|---|---|---|
| 1 GB | $3.99 / 7 days | $4.50 / 3 days | $0.51 cheaper and more than double the validity |
| 3 GB | $7.99 / 15 days | $9.00 / 7 days | $1 cheaper and double the validity |
For short trips, Travelsim Asia is the clear pick — cheaper and significantly longer validity on both plans.
Standard trips (5–20 GB)
For a 1–4 week trip with regular use: Grab and Gojek daily, WhatsApp for everything, maps, social media, and photo uploads.
| Data | Travelsim Asia | Airalo | Verdict |
|---|---|---|---|
| 5 GB / 30 days | $10.99 | $14.00 | $3.01 cheaper |
| 10 GB / 30 days | $16.99 | $22.00 | $5.01 cheaper |
| 20 GB / 30 days | $27.99 | $35.00 | $7.01 cheaper |
Unlike Japan where prices are within a dollar across providers, in Indonesia the gap widens with plan size. At 20 GB, Travelsim Asia is $7 cheaper — a 20% saving — for the same data and validity.
Extended stays (50 GB)
For Bali long-stays, digital nomads, or anyone hotspotting a laptop for a month.
| Data | Travelsim Asia | Airalo | Verdict |
|---|---|---|---|
| 50 GB / 30 days | $34.99 | $42.00 | $7.01 cheaper, same 30-day validity |
At 50 GB, Travelsim Asia's $0.70/GB rate is the lowest per-GB price for any Indonesia eSIM in the market — including all competitors not in this two-way comparison. Airalo's $0.84/GB is competitive but $7 more in absolute terms for the same data window.
Unlimited plans
Airalo offers "unlimited" Indonesia eSIMs. Travelsim Asia does not.
| Plan | Travelsim Asia | Airalo | Verdict |
|---|---|---|---|
| Unlimited / 7 days | — | $27.00 (3 GB/day FUP) | Only Airalo offers this |
| Unlimited / 30 days | — | $72.50 (3 GB/day FUP) | Only Airalo offers this |
Worth knowing: Airalo's "Unlimited" Indonesia plans aren't truly unlimited — they give 3 GB/day at full speed, then throttle to 1 Mbps. For most travelers, Travelsim Asia's fixed plans deliver more usable full-speed data per dollar. A 30-day Airalo unlimited at $72.50 caps you at ~90 GB total (3 GB × 30 days) of high-speed data; Travelsim Asia's 50 GB / 30 days at $34.99 gives you 50 GB of full-speed data for less than half the price. If you genuinely need uncapped unlimited, see our Holafly comparison instead.
Network coverage in Indonesia
Indonesia has five mobile networks, but only two really matter for travelers: Telkomsel (widest rural and island coverage) and XL Axiata (strong urban). The networks your eSIM connects to determine where it actually works.
Travelsim Asia
- Telkomsel ✓
- XL Axiata ✓
Indonesia's two largest networks
Airalo
- 3 (Hutchison) ✓
- Indosat Ooredoo ✓
No Telkomsel, no XL
This matters more than it sounds. Telkomsel has Indonesia's widest coverage — particularly outside Java and Bali. Lombok, Flores, Sumba, the Gili Islands, Komodo, Raja Ampat, Sumatra, Sulawesi — these are areas where Telkomsel signal holds when other networks thin out. Airalo's Indonesia eSIM doesn't include Telkomsel access, which means weaker performance once you leave the main tourist islands.
If your trip is entirely in Bali or Jakarta, both providers will work fine. If you're going beyond the well-trodden tourist path — even a day trip to Nusa Penida, a ferry to the Gilis, or any of the eastern islands — Telkomsel access becomes the deciding factor.
What about island ferries and remote diving?
Telkomsel holds signal further offshore than other Indonesian networks — relevant for ferry crossings to Lombok and the Gilis, liveaboard dive trips around Komodo, and longer island-hopping itineraries in Eastern Indonesia. Travelsim Asia includes Telkomsel; Airalo does not.
Buying and setup experience
This is where the two providers differ most.
Travelsim Asia
- No app required
- No account or sign-up
- Buy on the website, eSIM arrives by email
- Install via tap-to-install link or QR code
- Top up and check data through a web portal — no login needed
Airalo
- App required (iOS and Android)
- Account creation and sign-up required
- Buy and install through the app
- Install via QR code from the app
- Top up and manage data through the app
If you like having everything in one app, Airalo's approach makes sense — their app is well-designed and lets you manage multiple eSIMs across trips. But if you'd rather just buy what you need and get a QR code in your inbox without creating yet another account, Travelsim Asia is simpler. There's nothing to download, nothing to log into, and your data portal works in any browser.
Worth mentioning: Airalo's app also includes a loyalty program where you earn credits toward future eSIMs. If you travel frequently and use Airalo for every trip, that adds up. We don't have a loyalty program.
What's the same
- Data-only — no Indonesian phone number, no SMS. Use WhatsApp, FaceTime, or Skype for calls.
- No IMEI registration — both bypass Indonesia's 90-day IMEI registration requirement that applies to physical local SIMs.
- 5G support — where available and if your phone supports it.
- Prepaid — no bill shock. Data roaming needs to be switched on, but there's nothing extra to charge.
- Install before you fly — both let you install at home and activate when you land.
- Top-ups available — you can add more data without buying a whole new eSIM.
- Hotspot / tethering — works with both. Just remember it burns through data faster.
So, which one?
There's no wrong answer here — both will keep you connected in Indonesia. But depending on your trip, one fits better than the other.
Travelsim Asia might be better if you:
- Want to buy and go — no app, no account
- Want the lowest price at any data tier from 1 GB to 50 GB
- Plan to travel outside Bali and Jakarta (Lombok, Flores, Sumba, Sumatra)
- Prefer managing things from a browser instead of an app
- Need a large 50 GB plan for a Bali long-stay or remote work setup
Airalo might be better if you:
- Travel frequently and want loyalty rewards
- Prefer managing all your travel eSIMs in one app
- Are visiting multiple Southeast Asian countries on one eSIM (regional plan)
- Specifically want an "unlimited" plan (with 3 GB/day FUP)
- Are staying entirely in Bali or Jakarta where two networks is plenty
Frequently asked questions
💰 Is Travelsim Asia or Airalo cheaper for Indonesia?
Travelsim Asia is cheaper across every comparable plan size. The gap is smallest on 1 GB ($0.51 saving) and widest on 20 GB and 50 GB ($7 saving on each). On 3 GB, Travelsim Asia is $1 cheaper and also offers double the validity (15 days vs 7 days).
📶 Which networks do Travelsim Asia and Airalo use in Indonesia?
Travelsim Asia connects to Telkomsel and XL Axiata — Indonesia's two largest mobile networks. Airalo connects to 3 (Hutchison) and Indosat Ooredoo. Telkomsel access matters for travel outside Java and Bali, particularly to islands like Lombok, Flores, Sumba, and Sulawesi.
📱 Do I need an app to use Travelsim Asia or Airalo in Indonesia?
Travelsim Asia does not require an app or account. You buy on their website and receive your eSIM by email. Airalo requires downloading their app and creating an account before you can purchase and install an eSIM.
🏝️ Does Airalo work in Bali?
Yes. Airalo's Indonesia eSIM works well in Bali across all major areas (Seminyak, Canggu, Ubud, Uluwatu, Sanur, Nusa Dua). Coverage on Bali through Indosat and 3 is solid. Where Airalo's coverage weakens is outside Bali — particularly on the outer islands and rural Sumatra or Sulawesi, where Telkomsel access becomes important.
🌐 Does an Indonesia eSIM require IMEI registration?
No. Both Travelsim Asia and Airalo are international roaming eSIMs, not local Indonesian SIMs — so Indonesia's 90-day IMEI registration requirement does not apply. Only physical local SIM cards from Telkomsel, XL, Indosat, etc. require IMEI registration for tourists.
🔄 Can I top up my Indonesia eSIM if I run out of data?
Yes. Both providers support top-ups. Travelsim Asia lets you top up through a web portal with no login required. Airalo lets you top up through their app.
💬 Will WhatsApp work with an Indonesia eSIM?
Yes. Both Travelsim Asia and Airalo provide data-only eSIMs. WhatsApp, FaceTime, Telegram, Signal, and all other messaging and calling apps work over the data connection using your existing phone number. This matters in Indonesia, where WhatsApp is the default communication channel for villa hosts, tour guides, restaurants, and most small businesses.
🛵 Will Grab and Gojek work with an Indonesia eSIM?
Yes. Grab and Gojek work with any data connection. Both eSIMs provide reliable enough data for the constant location updates these ride-hail apps require. Just make sure your eSIM is your active data line and roaming is enabled.
Quick tips for using an eSIM in Indonesia
Install Grab and Gojek before your trip
Both are essential for transport across Indonesia. Install before you fly so you can book a ride the moment you land at Bali Ngurah Rai or Jakarta Soekarno-Hatta. Both also handle food delivery (GoFood, GrabFood) — useful for late-night villa cravings.
Pre-download offline maps for Bali
Bali's roads are a tangle of one-way scooter lanes that Google Maps gets wrong sometimes. Download the Bali region offline before you fly — your scooter rides will be smoother and you'll save 200–500 MB/day in map data.
Telkomsel matters for outer islands
If you're heading to Lombok, the Gili Islands, Komodo, Flores, Sumba, Raja Ampat, or anywhere in Sumatra or Sulawesi, prioritize a Telkomsel-connected eSIM. Airalo's 3 + Indosat combination works in Bali and Jakarta but thins out elsewhere.
Budget around 500 MB per day for typical tourist use
Grab/Gojek, WhatsApp, Google Maps, light social media. Heavy photo uploads or video calls will push that higher. If you're hotspotting a laptop in a Canggu café, budget 1–2 GB per day.
Ready to pick?
Both providers work. If you want the simplest possible experience — no app, no sign-up, Telkomsel + XL coverage, and the lowest prices on every plan size — we built Travelsim Asia specifically for that.
Prefer Airalo? No hard feelings — here's their Indonesia page. Either way, skip the airport SIM queue and the IMEI registration hassle.
