eSIM for Gili Trawangan
Gili Trawangan, known as Gili T, is the largest and liveliest of the three Gili Islands off Lombok, a car-free island of beach bars, diving, snorkelling and parties reached by fast boat. Of the Gilis it has the best coverage, with Telkomsel providing usable signal in most areas, though the small island's infrastructure is limited.
An eSIM Indonesia gives you access to the same plans in Gili Trawangan 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 Gili Trawangan
Gili Trawangan is reached by fast boat from Bali (around 1.5 to 2.5 hours) or a short hop from Lombok. Signal returns as you near the island. The island is car-free, getting around on foot, by bicycle or by cidomo horse cart. Telkomsel gives the most usable coverage, so a Telkomsel-based eSIM is the clear choice. Sort your accommodation and any dive bookings while connected, and download offline maps, since the small island's coverage, while the best of the Gilis, is still limited.

Coverage in Gili Trawangan
The Gili Islands have limited mobile infrastructure overall, but Gili Trawangan, the largest and most developed, has the best coverage of the three. Telkomsel provides usable signal in most areas of the island, especially around the main eastern strip where the boats arrive and the bars, dive shops and accommodation cluster. Coverage is patchier on the quieter western and northern sides, and the small island's infrastructure means dips even on Telkomsel. Other networks are weaker here. The dive and snorkel sites around the islands, including the famous turtle spots, lose signal over the water, and the fast-boat crossing from Bali is a dead zone.
Best network here
Telkomsel (the best signal on the Gilis); others weaker
| Area | Best network | What to expect |
|---|---|---|
| Main eastern strip | Telkomsel | Where boats arrive and bars cluster; the best-covered part of Gili T. |
| Harbour / village | Telkomsel | The arrival and local area; usable Telkomsel signal. |
| Accommodation belt | Telkomsel | Reasonable coverage around the eastern and southern stays. |
| Western / northern sides | Telkomsel | Quieter sides; coverage patchier, Telkomsel holds best. |
| Dive / snorkel sites | Telkomsel | Signal drops over the water at the turtle and reef spots. |
| Fast-boat crossing | Telkomsel | Dead zone over open water from Bali; reconnects near the island. |
Where to stay and connect in Gili Trawangan
Eastern strip
The main hub where boats arrive, with the bars, restaurants, dive shops and most accommodation. The best-covered part of the island and the lively heart of Gili T.
Harbour village
The local area near the boat landing, with markets and the night market food stalls, usable on Telkomsel. The practical centre.
Southern beaches
Quieter stays and swing-over-the-water spots along the south, reasonably covered. A calmer base within reach of the strip.
Western / northern sides
The quietest, most secluded parts with sunset views and fewer crowds. Coverage thins here; Telkomsel is the only usable option and even it dips.
Staying online while you move
Gili Trawangan is car-free and small, explored on foot, by bicycle or by cidomo horse cart, with the main eastern strip walkable. Coverage follows the development: usable on Telkomsel around the busy east, patchier on the quiet west and north. The island circuit by bicycle passes through low-signal stretches on the far side. The dive and snorkel sites around the Gilis lose signal over water, and the fast-boat crossing from Bali is a dead zone. Download offline maps and sort dive bookings while connected on the strip, and expect the quieter sides to dip even on Telkomsel.
How much data in Gili Trawangan
A few days on Gili T run on 4 to 6 GB, but coverage rather than volume is the limit on this small island. A Telkomsel-based eSIM is the clear choice, as other networks are weaker here. Use the eastern strip's coverage for uploads and bookings, download offline maps for the island circuit, and treat dive and snorkel trips as offline over the water. The party-island vibe also lends itself to switching off.
Apps worth having in Gili Trawangan
| App | Why it helps here |
|---|---|
| Telkomsel myTelkomsel | For managing a Telkomsel-based plan, by far the best network on the Gilis. Sort it before relying on the island's limited coverage. |
| Google Maps offline | Download Gili T before arriving; the quieter western and northern sides thin out and the crossing has no signal. |
| 12Go Asia / fast-boat apps | Book fast boats from Bali or Lombok. Download tickets before the crossing, which is a dead zone over open water. |
| Dive / PADI apps | Gili T is a major dive and snorkel spot for turtles; operators confirm trips, and the sites themselves are offline over water. |
| Offline notes | Save accommodation and dive details offline, since the quieter parts of the island dip even on Telkomsel. |

Gili Trawangan eSIM FAQ
Is there mobile coverage on Gili Trawangan?
Yes, the best of the three Gili Islands. Telkomsel provides usable signal in most areas, especially the busy eastern strip. The quieter western and northern sides are patchier, and the small island's infrastructure means dips even on Telkomsel.
Which network is best on the Gili Islands?
Telkomsel, clearly. It gives the most usable coverage on Gili T and the other Gilis, while other networks are weaker. A Telkomsel-based eSIM is the network to use across the islands.
Does Gili T have better coverage than Gili Air and Meno?
Yes. As the largest and most developed Gili, Gili Trawangan has the best coverage, with Telkomsel usable in most areas. Gili Air and Gili Meno have weaker and less consistent signal.
Will I have signal on the boat to Gili T?
No, the fast-boat crossing from Bali is a dead zone over open water, reconnecting near the island. Download maps and save your details before boarding.
Is there signal at the Gili dive and snorkel sites?
No, the sites are over the water and lose signal, including the famous turtle spots. Telkomsel reconnects near the island. Treat dive and snorkel trips as offline and confirm bookings on the strip first.
How much data do I need on Gili T?
