eSIM for Nusa Lembongan
Nusa Lembongan is the small, laid-back island between Bali and Nusa Penida, popular for its relaxed pace, surf breaks, snorkelling and the mangrove-fringed link to neighbouring Nusa Ceningan. Smaller and more developed for tourism than Penida, it has reasonable coverage in the main areas, with Telkomsel the safest across the island.
An eSIM Indonesia gives you access to the same plans in Nusa Lembongan 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 Nusa Lembongan
Nusa Lembongan is reached by a 30-to-45-minute fast boat from Sanur in Bali, landing at Jungut Batu or Mushroom Bay. Signal returns as you approach. The main beach areas have reasonable coverage, so arrange your stay and scooter on arrival. The island is small and walkable or scootered in parts, but coverage thins in the quieter corners and on the bridge to Nusa Ceningan, so download offline maps in Bali before crossing.

Coverage in Nusa Lembongan
Nusa Lembongan, being smaller and more tourism-developed than Nusa Penida, has reasonable coverage in its main areas. Jungut Batu, the main beach and accommodation strip, Mushroom Bay and the central areas have usable 4G on Telkomsel and XL. Telkomsel is the safest across the island. Coverage thins in the quieter corners, on the famous yellow suspension bridge linking to Nusa Ceningan, around the secluded beaches and on the water for snorkelling and diving trips. The neighbouring Nusa Ceningan is patchier still. The fast-boat crossing from Sanur loses signal over open water, returning near the island.
Best network here
Telkomsel (safest island-wide); XL usable in the main areas
| Area | Best network | What to expect |
|---|---|---|
| Jungut Batu | Telkomsel / XL | The main beach and accommodation strip; reasonable coverage on both. |
| Mushroom Bay | Telkomsel / XL | Popular bay with resorts; usable signal, Telkomsel steadier. |
| Central areas / village | Telkomsel | The island's interior and village; Telkomsel the safer network. |
| Yellow bridge / Nusa Ceningan | Telkomsel | The link to Ceningan; coverage thins, Telkomsel holds best. |
| Secluded beaches / Devil's Tear | Telkomsel | Quieter spots; signal can dip, Telkomsel the reliable option. |
| Snorkel / dive sites / crossing | Telkomsel | Signal drops over open water on trips and the Sanur crossing. |
Where to stay and connect in Nusa Lembongan
Jungut Batu
The main beachfront strip with most guesthouses, warungs and the surf breaks, with the island's best coverage. The practical base for a Lembongan stay.
Mushroom Bay
A pretty bay with resorts and calm swimming, popular with day-trippers, reasonably covered. A slightly more upscale base than Jungut Batu.
Central village
The local interior of the island away from the beaches, where Telkomsel is the steadier network. Quieter and more authentic.
Toward Ceningan
The area around the yellow suspension bridge to Nusa Ceningan, with the Blue Lagoon and cliff spots. Coverage thins; Telkomsel holds best on the link.
Staying online while you move
Nusa Lembongan is small, explored on foot, by scooter or by hired driver, and the main beach areas stay reasonably covered. The quieter corners, the famous yellow bridge to Nusa Ceningan and the secluded beaches thin out, with Telkomsel holding best. The snorkelling and diving trips around the islands and the fast-boat crossing from Sanur lose signal over open water. For exploring beyond the main strip and crossing to Ceningan, download offline maps in Bali before you go, and use a Telkomsel-based eSIM for the quieter parts of the island.
How much data in Nusa Lembongan
A relaxed stay on Nusa Lembongan runs on 4 to 6 GB, mostly in the well-covered main beach areas. Coverage thins in the quieter corners and on the water, so a Telkomsel-based eSIM is the safer choice and offline maps help for Ceningan and the secluded beaches. Use the Jungut Batu and Mushroom Bay coverage for uploads, and treat snorkel and dive trips as partly offline.
Apps worth having in Nusa Lembongan
| App | Why it helps here |
|---|---|
| Google Maps offline | Download Nusa Lembongan and Ceningan in Bali before crossing; the quieter corners and the bridge area thin out. |
| 12Go Asia / fast-boat apps | Book the Sanur fast boat. Download tickets before the crossing, which loses signal over open water. |
| Telkomsel myTelkomsel | For managing a Telkomsel-based plan, the safest network across the island. Sort it before relying on the patchier corners. |
| Dive / snorkel apps | Lembongan is known for manta and mola-mola diving; operators confirm trips, and the sites themselves are offline over water. |
| Offline notes | Save your accommodation and driver details offline, since the quieter parts of the small island can drop signal. |

Nusa Lembongan eSIM FAQ
Is there mobile coverage on Nusa Lembongan?
Reasonable in the main areas like Jungut Batu and Mushroom Bay on Telkomsel and XL, better than neighbouring Nusa Penida thanks to its smaller, more developed size. The quieter corners, the Ceningan link and the water thin out, where Telkomsel is safest.
Which network is best on Nusa Lembongan?
Telkomsel. It is the safest across the island, including the quieter corners and the bridge to Nusa Ceningan. XL is usable in the main beach areas, but a Telkomsel-based eSIM is the reliable choice.
Will I have signal on the boat to Nusa Lembongan?
No, not over open water. The fast-boat crossing from Sanur loses signal mid-way, returning near the island. Download maps and save your details in Bali before boarding.
Is there signal on Nusa Ceningan and the yellow bridge?
It thins. The famous yellow suspension bridge to Ceningan and the neighbouring island are patchier, with Telkomsel holding best. Download offline maps before exploring across the bridge.
How much data do I need on Nusa Lembongan?
4 to 6 GB covers a relaxed stay, mostly in the well-covered main beaches. Coverage thins in the quieter corners and on the water, so a Telkomsel-based eSIM matters more than the data size.
Is Nusa Lembongan better covered than Nusa Penida?
Yes, somewhat. Being smaller and more tourism-developed, its main areas have more reasonable coverage than rugged Penida. But both rely on Telkomsel as the safest network, and both have low-signal corners and offshore gaps.
