Komodo & Raja Ampat: offline guide
Komodo and Raja Ampat represent the extremes of Indonesia's connectivity spectrum. Labuan Bajo, the gateway to Komodo, has Telkomsel 4G in town. Komodo Island and the national park boat routes have no signal at all. Raja Ampat goes further: mobile coverage is essentially absent across the entire island group outside the gateway city of Sorong. Both destinations require complete offline preparation. Here is exactly what that means.
These are the two destinations where connectivity planning is a safety question, not a convenience one. Prepare in Labuan Bajo and Sorong. Do not assume signal will appear in the water.
Komodo National Park: honest coverage
| Location | Coverage | Notes |
|---|---|---|
| Labuan Bajo (Flores) | Telkomsel 4G | Your last prep window. Use it fully. |
| Boat from Labuan Bajo | None after harbor | Signal disappears within minutes of departure. |
| Komodo Island | None | No mobile coverage on the island itself. |
| Rinca Island | None | Same as Komodo. Full offline. |
| Pink Beach / other sites | None | No signal at any of the park's main attractions. |
| Return to Labuan Bajo | Telkomsel 4G returns | Signal comes back as you approach the harbor. |
- Download the complete offline map of Komodo National Park and Flores.
- Screenshot your boat operator's phone number and the park entry confirmation.
- Share your itinerary and expected return date with someone outside Indonesia.
- Download any entertainment for evenings on the boat.
- Confirm your post-Komodo accommodation booking is saved offline.
Raja Ampat: plan for zero signal
Raja Ampat in West Papua is one of the most biodiverse marine environments on earth and one of the least connected destinations in Asia. Over 75% of the world's coral species are found here. Mobile phone signal is not among them.
| Location | Coverage | Notes |
|---|---|---|
| Sorong (gateway city) | Telkomsel 4G | Your only signal before and after. Use Sorong fully. |
| Flight/boat from Sorong | None after departure | Signal ends at the Sorong harbor or airport. |
| Waigeo, Batanta, Salawati, Misool | None | The four main islands of Raja Ampat: no mobile signal. |
| Wayag | None | The iconic lagoon viewpoint: complete offline. |
| Liveaboard dive boats | None | Some boats have Starlink satellite internet for emergencies. Ask your operator. |
| Resorts | Satellite wifi at some | Quality varies. Do not assume connectivity. Confirm with your resort before booking. |
Sorong is the last city before Raja Ampat. Do everything digital in Sorong: download all maps, save all confirmations, share your full itinerary with a contact outside Indonesia, and withdraw Indonesian Rupiah in cash. ATMs are not available on the islands. Card payments are rare. Your eSIM data ends in Sorong harbor.
What your eSIM is useful for in these destinations
In Labuan Bajo and Sorong, your Telkomsel-backed eSIM is exactly as useful as anywhere else: Gojek (where available), maps, accommodation booking, communication. The dead zones are the destination, not the transit. Budget your data for the gateway cities and the return, not for the park or the archipelago itself.

FAQ
Is there any signal in Raja Ampat?
Rarely outside Sorong. On the Raja Ampat islands including Waigeo, Batanta, Salawati, Misool and Wayag, mobile coverage is essentially absent. Some resorts have satellite internet for guests. Some liveaboard dive boats have Starlink for emergencies. Plan Raja Ampat as a completely offline destination and complete all digital preparation in Sorong before boarding.
Is there signal in Komodo National Park?
Not on the islands or during boat trips in the park. Labuan Bajo on Flores has Telkomsel 4G coverage in town. Signal disappears shortly after leaving the harbor and does not return until you approach Labuan Bajo on the way back. Download everything in Labuan Bajo before departure.
Do I need cash in Raja Ampat?
Yes. ATMs are not available on the Raja Ampat islands. Card payments are rare in the villages and most small warungs. Withdraw Indonesian Rupiah in Sorong before boarding, enough for the full duration of your stay plus a buffer. Your liveaboard or resort charter is typically pre-paid, but village visits, tips and market purchases need cash.
Can my eSIM work in Raja Ampat if I have Telkomsel?
Telkomsel has better remote coverage than any other Indonesian operator, but Raja Ampat is beyond its consistent reach. Even a Telkomsel-backed eSIM will have no signal on the islands. Sorong has Telkomsel 4G. The islands do not. This is a geography limitation, not an operator failure.
