The short answer
Arrive at Labuan Bajo with an eSIM already installed, sort out everything that needs the internet while you are still in town, and accept that the park itself is offline. Komodo Airport is the gateway to Komodo National Park, it is small, and its scheduled services are essentially domestic as of July 2026. Town has usable 4G on Telkomsel, the network with the widest reach in Indonesia. Out on the water it is a different story, and no amount of shopping around for a SIM changes that.
A small airport right beside town
Komodo Airport sits a couple of kilometres from Labuan Bajo, so the transfer is a short drive rather than a journey. One terminal handles arrivals and departures, and most people are outside within minutes of the bags appearing. Taxis, hotel drivers and tour operators wait in the arrivals hall. The distance is short enough that travelling light and walking is not absurd, though the heat and the road usually decide that for you. Facilities are modest: a handful of cafes and shops, and quiet stretches between flights.
Getting online when you land
An eSIM installed at home attaches to the local network on its own, which is the whole point at an airport this size. Free Wi-Fi may be available in the terminal, but at a small airport a public network is a weak thing to depend on, and it ends at the doors anyway. Switch off airplane mode, enable data roaming on the travel eSIM line, set it as your data line, and you are connected before you reach the car park. That is enough to confirm a boat, a pickup or a room.
SIM counter or an eSIM you already have
You can usually buy a local SIM in Labuan Bajo, but the airport is the worst place to do it and the day you sail is the worst time. Every Indonesian SIM has to be registered against a passport, so a counter purchase means forms rather than a quick sale, and airport pricing runs above the in-town rate. A Goodbars eSIM is scanned at home on your own Wi-Fi and is live on Telkomsel when you land. If your phone has no eSIM support, buy in town rather than at the terminal.
Town has signal, the park does not
This is the honest bit: Labuan Bajo has workable 4G, and Komodo National Park largely does not. In town, Telkomsel handles maps, messaging, calls and booking without much drama. Once a boat leaves the harbour, coverage drops away fast. Some spots near the bigger islands may give you a bar or two, but nothing you can plan around, and multi-day trips are effectively offline unless the boat carries its own satellite internet. Treat that as part of the experience rather than a fault in your connection.
What to do before the boat leaves
Do your online admin in town, on purpose, before the harbour. Download offline maps of Flores and the park. Save your boat booking, operator contact and accommodation details as screenshots. Send the people who track you a message saying you will be out of signal for the next few days, with a rough return time. Check the weather forecast before you leave rather than hoping to check it later. Then let the phone go quiet, and use the data you have left when you get back to town.
