eSIM for Flores
Flores is a long, mountainous island in eastern Indonesia, stretching from the Komodo gateway of Labuan Bajo in the west to the tricoloured crater lakes of Kelimutu in the east. Coverage follows the towns along the Trans-Flores Highway, but the mountainous interior and remote stretches thin out, with Telkomsel the only network with real reach.
An eSIM Indonesia gives you access to the same plans in Flores 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 Flores
Flores is usually entered at Labuan Bajo in the west, the Komodo gateway with an airport, or at Ende or Maumere further east. The towns have coverage, best on Telkomsel. Many travellers drive the Trans-Flores Highway across the island, a multi-day mountainous journey. Sort your Telkomsel-based eSIM in a town, download offline maps for the whole route, and plan for long stretches of weak or no signal through the rugged interior between the covered towns.

Coverage in Flores
Flores is a long, mountainous island, and coverage concentrates in the towns strung along the Trans-Flores Highway. Labuan Bajo in the west, the increasingly developed Komodo gateway, has good coverage; Ruteng, Bajawa, Ende and Maumere, the main towns across the island, have usable Telkomsel signal. Telkomsel is the only network with real reach here. Between the towns, the highway winds through dramatic mountains, rice terraces and remote villages where coverage thins to nothing for long stretches. The Kelimutu crater lakes, a sunrise highlight near Moni, are reached through rural country, and the traditional villages and remote south coast are largely offline. Other networks barely register outside the main towns.

| Ruteng / Bajawa | Telkomsel | Highland towns on the highway; usable Telkomsel signal. |
| Ende / Maumere (east) | Telkomsel | Main eastern towns with airports; Telkomsel reliable. |
| Kelimutu / Moni | Telkomsel | The crater-lake area; Telkomsel in Moni, thinning toward the lakes. |

Where to stay and connect in Flores
Labuan Bajo
The booming western gateway to Komodo, with the most development, hotels and the best coverage on Flores. The main entry and exit point and the place to prepare.
Moni (Kelimutu)
The small village base for the Kelimutu crater-lake sunrise, with usable Telkomsel signal. Coverage thins on the climb to the lakes themselves.
Bajawa / Ruteng
Highland towns on the Trans-Flores route, gateways to traditional villages and rice terraces. Usable Telkomsel coverage in town, thinning in the surrounding country.
Ende / Maumere
The main eastern towns with airports and ports, reliably covered on Telkomsel. Practical bases for the eastern end of the island.
Staying online while you move
Flores is experienced by driving the Trans-Flores Highway, a spectacular multi-day journey across mountains, past volcanoes, rice terraces and traditional villages. Coverage follows the towns: usable on Telkomsel in Labuan Bajo, Ruteng, Bajawa, Ende, Moni and Maumere, but the long stretches of winding mountain road between them thin to nothing. The Kelimutu crater lakes and the remote villages and south coast are largely offline. Other networks barely work outside the towns. A Telkomsel-based eSIM is essential, offline maps of the entire route are critical, and you should plan for long disconnected stretches.
How much data in Flores
A Trans-Flores trip runs on relatively little data because so much of the journey is offline: 4 to 6 GB covers the towns where Telkomsel reaches. The network rather than the volume is what matters: a Telkomsel-based eSIM is essential, as other networks barely register outside the main towns. Download offline maps of the whole highway and your stops before setting off, use the town coverage to check in, and treat the mountainous stretches between as disconnected.
Apps worth having in Flores
| App | Why it helps here |
|---|---|
| Google Maps offline | Critical. Download the entire Trans-Flores Highway and your stops, since long mountainous stretches between towns have no signal. |
| Telkomsel myTelkomsel | For managing a Telkomsel-based plan, the only network with real reach across Flores. Sort it in a town before driving the interior. |
| Tour / driver operators | Many do the Trans-Flores route with a hired driver; confirm the itinerary and stops while connected in town. |
| Offline notes | Save your accommodation, driver contact and route details offline, since the highway has long no-signal stretches. |
| Weather apps | Check conditions before the Kelimutu sunrise and mountain drives; the highland weather and roads can be challenging. |
