For a short Komodo and Labuan Bajo trip, our pick is Travelsim Asia's 5 GB Indonesia eSIM at $10.99 for 30 days. It includes Telkomsel and installs from email without an app or account. For a smaller allowance with the same 30-day validity, Nomad's 3 GB plan costs $8. Whichever you choose, expect gaps in mobile service during the boat trip.
We sell the Travelsim Asia plan. Our recommendation comes down to Telkomsel access, the allowance you need and how long it lasts. Where another provider is a better fit, we say so.
The short answer for Komodo
- Our pick for a short trip: Travelsim Asia, 5 GB for $10.99 over 30 days. Telkomsel included, email installation and web-portal top-ups.
- For light use over a longer itinerary: Nomad, 3 GB for $8 over 30 days on Telkomsel. Our 3 GB costs $7.99 but lasts 15 days; Nomad buys you twice the validity for one cent more.
- Already have an Indonesia eSIM? Keep it if it includes Telkomsel and has enough data and validity left. You don't need another plan just for Komodo.
- Need internet throughout a liveaboard trip? Check the specific boat's satellite service. A bigger mobile allowance cannot fix a coverage gap at sea.

Travelsim Asia or Nomad: which plan fits your trip?
We recommend 5 GB for a short Labuan Bajo stay and boat excursion because it leaves more room for your days on land and photo sharing. If you keep uploads on Wi-Fi and only need messages and bookings, 3 GB is a smaller starting option. Size either allowance for your whole Indonesia itinerary; these are planning choices, not measured averages for Komodo visitors.
| Plan | Validity | Price |
|---|---|---|
| Travelsim Asia, 3 GB | 15 days | $7.99 |
| Nomad, 3 GB | 30 days | $8.00 |
| Travelsim Asia, 5 GB | 30 days | $10.99 |
| Nomad, 5 GB | 30 days | $12.00 |
Nomad's longer 3 GB validity is the better fit if you need those extra days. At 5 GB for 30 days, ours costs $1.01 less. These are standard USD prices from our 5 October Indonesia comparison, excluding promotions. Neither price nor network access proves that one provider will be faster on your boat.
Our eSIM installs from the email, without an app or account, and you can add data through the linked web portal. If you need an Indonesian number for ordinary calls or SMS, compare a local Telkomsel offer instead: our travel plan is data only. Telkomsel lists a GraPARI service location in Labuan Bajo; check current opening hours and purchase requirements directly.
Why we would choose Telkomsel access for Komodo
Telkomsel is our first network criterion for this route. Alongside its documented local infrastructure, boat operator Komodo Luxury recommends a Telkomsel SIM in its speedboat packing advice. That gives us a destination-specific reason to recommend it, rather than assuming every Indonesia plan is equally suitable.
Look for the name Telkomsel in the exact plan's network list before paying. An “Indonesia” label tells you the destination included, but providers can use different Indonesian networks. Our plan lists Telkomsel alongside other partner networks. Those extra options can help elsewhere on your itinerary; they don't establish coverage at a particular Komodo bay.
You also don't have to buy from us to get Telkomsel. Nomad and Airalo include it in the plans captured in our October comparison. If you already have a suitable plan, check its remaining allowance and expiry before purchasing another one.
Labuan Bajo and the national park are different connectivity questions
Labuan Bajo is the town on Flores where you arrange transfers, meet your crew and board for Komodo. A search for a “Komodo eSIM” usually covers both the time in town and the boat trip, but a connection that works at your hotel says little about the next day's anchorage.
Telkomsel has documented network investment around Labuan Bajo, including the airport and hotels. Its 2023 ASEAN summit report also describes work along the sea route towards Rinca. That is evidence of infrastructure in the area, not a current signal test for every visitor route.
For your own trip, separate the places where you can sort things out from the places where you can happily wait:
| Part of the trip | How to plan your connection |
|---|---|
| Labuan Bajo, your hotel and departure point | Install and test the eSIM, contact the crew, download bookings and finish large uploads before sailing. |
| Komodo, Rinca, Padar and beach stops | Save the itinerary offline. We do not have verified, stop-by-stop signal measurements for these locations. |
| Sea crossings and overnight anchorages | Expect periods without usable mobile data. Ask the operator about the internet available on your specific boat. |
A day trip lets you catch up when you return to town. On a multi-night sailing, tell anyone expecting regular replies that you may be offline. If you have a work deadline, arrange the connection around it before booking the boat.
Ask what “Wi-Fi on board” actually means
Before a liveaboard trip, ask whether the boat's internet comes from a mobile router or a satellite service such as Starlink. A mobile router still depends on cellular reception. A satellite-equipped boat is a separate service from the eSIM on your phone.
Komodo Luxury's onboard connectivity guide distinguishes mobile access around Labuan Bajo from internet at sea and identifies satellite-equipped vessels. The useful question is about the boat you booked: is guest internet included, is there an allowance, and is it suitable for the call or upload you need?
Buying a larger or unlimited mobile plan will not fix an area without coverage. For a sailing spent mostly offline, a modest eSIM allowance for the days before and after the boat can be enough. Spend more on data because you expect to use more, not because the destination is remote.
Coming from Bali, or travelling further through Flores?
An Indonesia eSIM can cover Bali, Labuan Bajo and the Komodo area under the same country's plan, wherever its supported networks have service. You don't need a separate Komodo product simply because you fly from Bali to Flores.
If you've already used the eSIM in Bali, check how much data and validity remain. Moving to another Indonesian island doesn't give you a fresh allowance or restart the plan. Size the purchase for the whole itinerary, including the days after your sailing.
For example, budgeting 0.5 GB on each of eight days when you expect to use mobile data gives 4 GB. A 5 GB plan would leave 1 GB spare. That's a calculation based on your assumed use, not a local usage study. Regular video calls, hotspot work or automatic photo backups need a separate budget. Our Indonesia data guide helps you choose; the Bali guide covers the earlier stop.
Do these checks before the boat leaves
- Check that your phone supports eSIM and is carrier-unlocked. Install while you have Wi-Fi, following the Indonesia installation guide.
- In Labuan Bajo, select the travel eSIM for mobile data and enable roaming on that line. Keep home-line data roaming and automatic data switching off. Turn off Wi-Fi briefly and load a page to check the connection.
- Save the crew's contact details, meeting point, hotel address and booking confirmations offline. Download any maps you will need before departure.
- Check your balance and the boat's internet arrangements. Turn off automatic cloud backups if you want to save the allowance for messages and travel logistics.
If mobile data stops working after you leave town, first distinguish a coverage gap from an installation problem. When you return to a known connected area, check that the correct data line and roaming are still enabled. If automatic selection fails, try Telkomsel manually if it is allowed by your plan. Don't delete the eSIM as a first troubleshooting step.
For this route, we'd start with Telkomsel access, enough data for the land days, and the boat's connectivity details settled before departure. View our Indonesia plans, or return to the Indonesia eSIM guides to compare the rest of your trip.
How we checked this guide
Plan prices come from our dated Indonesia comparison. Telkomsel's infrastructure report is historical; the boat operator's guidance is operational advice, not independent network testing. We have not assigned signal ratings to Padar, Pink Beach or individual anchorages. The sources linked beside each claim explain what the recommendation rests on.
