eSIM for Bunaken
Bunaken is a small island marine park off North Sulawesi near Manado, world-renowned for its dramatic coral walls and diving. As a remote island in a marine national park, it has limited coverage, with Telkomsel reaching the island patchily, while the gateway city of Manado on the mainland is fully connected.
An eSIM Indonesia gives you access to the same plans in Bunaken 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 Bunaken
Bunaken is reached by boat from Manado, the capital of North Sulawesi, around 30 to 45 minutes across the bay. Manado has a city airport and full coverage, so this is where you prepare: activate your Telkomsel-based eSIM, download maps and confirm your resort and dive bookings. Signal becomes patchy on the boat and the island, so sort everything in Manado first. Bunaken's resorts have varying coverage and some offer wifi, but plan the diving as largely offline.

Coverage in Bunaken
Manado, the mainland gateway city, has full, normal coverage on all networks including some 5G, so the mainland side of a Bunaken trip is well connected. Bunaken island itself, within a marine national park, has limited coverage: Telkomsel reaches the island patchily around the main village and the dive resorts, while other networks are weak or absent. The island's interior and quieter shores thin out further. The famous dive sites, the dramatic coral walls and drop-offs that draw divers worldwide, are over the water and offline. The boat crossing from Manado has patchy signal. Some resorts offer wifi, but Bunaken is best treated as a largely offline diving escape.

Where to stay and connect in Bunaken
Manado
The fully covered mainland gateway city with the airport, hotels and the boats to Bunaken. The place to prepare, download and message before crossing to the island.
Bunaken village
The main settlement on the island, with local life and some homestays, and patchy Telkomsel coverage. The most connected part of the island, relatively speaking.
Dive resorts
The dive-focused resorts around the island, the main reason to stay. Coverage varies and some offer wifi; confirm with your resort, but plan the diving as offline.
Quiet shores
The calmer parts of the island away from the village and resorts. Coverage thins to weak Telkomsel only; choose for solitude and accept being offline.
Staying online while you move
A Bunaken trip splits clearly: the mainland gateway of Manado is fully covered, while the island and its diving are largely offline. The boat crossing from Manado has patchy signal. On the island, getting around is on foot or by local boat, with patchy Telkomsel coverage around the village and resorts thinning elsewhere. The world-class dive sites, the coral walls and drop-offs, are over the water and offline. Prepare everything in Manado, download offline maps and information, confirm resort and dive bookings, and treat the island and diving as a disconnected escape, with resort wifi as the only likely connection.
How much data in Bunaken
Bunaken needs little data because the island and diving are largely offline: 2 to 4 GB covers the trip, used mainly in well-covered Manado. A Telkomsel-based eSIM gives the best chance of patchy signal on the island, but the dive sites are offline regardless. Download everything in Manado, confirm bookings, and treat Bunaken as a diving escape where resort wifi, not mobile data, is the occasional link to the outside world.
