eSIM for Raja Ampat
Raja Ampat, an archipelago off West Papua, is one of the most remote and biodiverse marine destinations on earth, a bucket-list diving paradise of karst islands and pristine reefs. This is the frontier of Indonesian connectivity: coverage is minimal, concentrated at a few points, and even Telkomsel reaches only the main hubs, so a trip here is largely offline.
An eSIM Indonesia gives you access to the same plans in Raja Ampat as in the rest of the country. 5 GB is generally enough for maps, messaging and social media, while video streaming and hotspot use require more data. The plans shown range from 1 to 50 GB and start at $1.90. They are fully refundable within 30 days provided the eSIM has not been used on a network at the destination. The activation link is sent by email after purchase.
Getting connected in Raja Ampat
Reaching Raja Ampat is a journey: fly to Sorong in West Papua, then take a ferry to Waisai, the small capital on Waigeo island, before transferring by boat to your homestay or resort. Sort your Telkomsel-based eSIM and download everything in Sorong, which has city coverage, because once you are in the islands, connectivity is minimal. Waisai and some accommodation have patchy Telkomsel signal, but plan your trip as largely offline and confirm logistics before leaving Sorong.

Coverage in Raja Ampat
Raja Ampat is the frontier of Indonesian mobile coverage. Telkomsel, the only network with any meaningful presence in remote eastern Indonesia, reaches Waisai, the small capital on Waigeo, and provides patchy signal at some of the larger homestays and resorts. Beyond these few points, there is essentially no coverage: the world-class dive sites, the iconic Piaynemo and Wayag karst viewpoints, the remote island homestays and the liveaboard boats operate with no mobile signal. Other networks are absent. Sorong, the mainland gateway city, has normal city coverage, so this is where you prepare. A Raja Ampat trip is, by its nature, one of Indonesia's most disconnected experiences.
Best network here

| Waisai (capital, Waigeo) | Telkomsel | The small island capital; patchy Telkomsel signal. |
| Larger homestays / resorts | Telkomsel | Some have patchy Telkomsel; many have none. Confirm in advance. |
| Dive sites | Telkomsel | World-class reefs; no signal, fully offline over the water. |

Where to stay and connect in Raja Ampat
Sorong
The mainland gateway city in West Papua, with normal coverage, the airport and the ferry to Waisai. The place to prepare, download and message before heading into the islands.
Waisai
The small capital on Waigeo island, with the main services and patchy Telkomsel signal. The transit point to the homestays and resorts; sort final logistics here.
Homestays (Arborek, Kri etc.)
Simple island homestays near the reefs, the classic Raja Ampat stay. Coverage ranges from patchy Telkomsel to none; confirm with your host and expect to be offline.
Resorts / liveaboards
Dive resorts and liveaboard boats reaching the remote sites. Largely offline; some resorts have limited wifi, but the diving experience is disconnected.
Staying online while you move
Getting around Raja Ampat is entirely by boat between islands, and this is where connectivity disappears. Beyond patchy Telkomsel signal at Waisai and some larger accommodation, the inter-island boat trips, the dive sites, the karst viewpoints at Piaynemo and Wayag, and the liveaboard journeys have no mobile coverage. Other networks are absent throughout. The mainland gateway of Sorong has normal coverage. Prepare everything there or in Waisai, download offline maps and information, confirm all logistics and accommodation, and accept that a Raja Ampat trip is among the most genuinely offline travel in Indonesia.
How much data in Raja Ampat
Raja Ampat needs almost no data because it is offline by nature: 2 to 3 GB covers the trip, used mainly in Sorong and Waisai. A Telkomsel-based eSIM gives the only chance of any signal in the islands, but no plan changes the fact that the dive sites and remote islands have none. Download everything in Sorong, including offline maps and your full itinerary, and treat the diving and island time as a complete and welcome disconnection.
Apps worth having in Raja Ampat
| App | Why it helps here |
|---|---|
| Google Maps offline | Essential, downloaded in Sorong. The islands have no coverage, so offline maps and saved locations are your only navigation reference. |
| Telkomsel myTelkomsel | For managing a Telkomsel-based plan, the only network reaching the hubs. Sort it in Sorong before heading to the islands. |
| Dive operator / liveaboard info | Download all itinerary, dive site and safety information from your operator, since the trip is offline for days at a time. |
| Offline notes | Save your full itinerary, homestay and operator contacts, and emergency details offline; you will be unreachable in the islands. |
| Marine / dive log apps | Log dives and review the famous marine life offline; Raja Ampat is a bucket-list dive destination you experience without signal. |
