Short answer: some Komodo liveaboards now carry Starlink and give usable internet at anchor, but many boats have no connection at all — and even on a connected vessel, expect stretches from several hours to a full day with nothing. Treat wifi on a Komodo liveaboard as a bonus that may or may not appear, never as a service you can build your week around.

Crews hear this constantly in Labuan Bajo. The answer has three parts: mobile coverage inside the park, what satellite internet delivers at sea, and what to arrange on land before you cast off — across every route in our Komodo liveaboard guide.
How strong is the mobile signal inside Komodo National Park?
Labuan Bajo has solid 4G, and Telkomsel has the widest coverage in East Nusa Tenggara. Once you leave the harbour, coverage stops being about your carrier and becomes geography: bars when a tower on Flores has line of sight to you, nothing behind the islands.
Expect a weak but workable signal for the first hour out of Labuan Bajo, patchy reception around Rinca, an occasional single bar on the ridgelines at Padar and Pink Beach — people genuinely climb the hill to send messages — and effectively nothing across the northern sites on our dive sites hub. Coverage flickers under way too: a burst mid-channel, then gone.
What does Starlink actually change on a Komodo liveaboard?
Satellite internet has genuinely changed the picture. A properly installed flat-panel terminal works far from any tower, including under way, and on a calm evening at anchor it carries messaging, email and photo uploads for a full guest list.
What it does not do is turn a dive boat into an office. Bandwidth is shared, so a dozen guests uploading footage after the third dive slows everything to a crawl, and squalls degrade the link. The terminal draws from the generator, so many operators run it in windows — usually after dinner — and switch it off during briefings and night passages. Some boats include it in the fare, others treat it as an extra, so read the vessel’s inclusions list. Boats in the luxury yacht category are the most likely to have one running.
The operative word is some: two boats leaving the same pier at similar fares can differ completely. Ask before booking — does this vessel have satellite internet, and when is it on?
When will you be genuinely offline?
- Overnight repositioning legs. The boat moves north after dinner; you wake up out of range.
- Full days in the north. Three or four dives and a sunset landing, all outside coverage.
- Long crossings. Itineraries reaching east spend hours with no tower on any horizon.
- Any satellite-free boat, once the harbour is behind you.
Shorter open trips stay near Labuan Bajo and catch more incidental signal; longer itineraries push north and east, which is why the diving is better and why the phone stops working. Compare routes on our packages page.
Should you buy an Indonesian SIM before boarding?
Yes, if you want any chance of local coverage. Buy a Telkomsel prepaid SIM or eSIM at Denpasar airport or in Labuan Bajo town — bring your passport, as registration is required — and load enough data for the trip, since top-up is impossible at sea. Roaming works too, but it is the expensive way to receive the same single bar.
Keep the phone in airplane mode between check-ins; a handset hunting for a network it cannot find flattens its battery faster than anything else aboard. Sort it out on land, with the other steps in our Labuan Bajo departure guide.
How do you tell family you will be out of contact?
This is the part guests most underestimate. Send your household the itinerary with the boat name and the operator’s Labuan Bajo office number — a shore office that answers the phone beats any onboard wifi. State plainly that silence is expected: “you will not hear from me between Tuesday and Thursday evening” removes the ambiguity that causes panic. Nominate one contact person, not five. If you cannot be unreachable at all, a satellite messenger such as an inReach or Zoleo works where phones do not.
Every properly run vessel carries a communication chain independent of guest wifi — VHF to nearby boats and the harbourmaster, a satellite phone, an EPIRB — and that is the layer that matters in a real incident; our crew and safety standards page sets out what should be aboard. Komodo Luxury — which keeps a shore desk in Labuan Bajo to relay messages between its vessels and families at home — lists its fleet and routes on the Komodo liveaboard page.
Does the August 2026 earthquake change how you plan communications?
It reinforces the same advice. The M7.7 earthquake of 15 August 2026 had its epicentre roughly 200 km northeast of Labuan Bajo; the harbour authority reopened sailing the same day under Maklumat 05/MP-VIII/2026, Komodo National Park was not closed, and conditions have held so far. The lesson: when something newsworthy happens in eastern Indonesia, families see the headline long before an offline guest can answer it. Agree in advance where they should look — BMKG for seismic and weather advisories, harbourmaster notices for sailing status, the operator’s shore desk for the boat.
What should you pack to stay powered?
Cabins usually have 220V sockets (type C/F plugs) but few of them, and generators are sometimes shut down overnight. Bring a power bank in the 20,000 mAh class in your carry-on, a multi-port charger, and a dry bag for tenders. Download maps, books and an image of your certification card before you sail, and pack spare camera batteries. If connectivity is non-negotiable, say so at enquiry stage: an operator can steer you to a satellite-equipped vessel or a route within reach of Flores, and our price guide explains where onboard extras sit relative to the fare. For full control of schedule and equipment, a private yacht charter or a luxury phinisi gives you the most say.
Frequently asked questions
Do all Komodo liveaboards have wifi?
No. Satellite internet is becoming common on larger vessels, but many boats in Komodo have none. Ask about the specific vessel rather than the operator, since most fleets are mixed.
Does Starlink work while the boat is moving?
A maritime-grade terminal is built to hold the link under way, and in calm conditions it does. Expect degradation in heavy rain and rough crossings, and expect the crew to switch it off during briefings or to manage power.
Can I work remotely from a Komodo liveaboard?
Email and messaging, sometimes. Scheduled video calls, not reliably — diving fills the daylight hours, bandwidth is shared, and the northern sites have no coverage. Hold anything unmissable in Labuan Bajo.
Which mobile network works best in Komodo?
Telkomsel has the broadest reach across Flores and the surrounding waters, making it the default choice. Even so, coverage stops well short of the northern dive sites, so no SIM keeps you connected throughout the park.
What happens in an emergency if there is no phone signal?
The boat’s own systems take over: VHF to nearby vessels and the harbourmaster, satellite phone to the shore office, an EPIRB for distress alerting, and a documented evacuation route toward Labuan Bajo. Guest wifi plays no part in that chain — which is why crew equipment and training matter more than signal bars.
Book the boat for the diving, not the bandwidth. Buy a Telkomsel SIM, carry a power bank, tell one person at home exactly when you will be silent, and ask the operator whether your vessel has satellite internet.
