Short answer
The best eSIM for Nusa Penida is BaliSIM Bali Visitor eSIM on Telkomsel. Coverage is solid at Toyapakeh, Kelingking, and Broken Beach — but patchy at Crystal Bay and nonexistent at Atuh and Diamond Beach. Download offline maps before you board the fast boat from Bali.
Nusa Penida is where Bali's Instagram photos come from. Kelingking Beach, Broken Beach, Angel's Billabong, Crystal Bay — every one of them is on Nusa Penida, a 40-minute fast boat from Sanur or Padang Bai. It's also the place where travelers most commonly discover that Bali-level connectivity does not automatically extend to Bali's neighbouring islands.
This guide covers what coverage actually looks like across Nusa Penida's main destinations, why the network you choose matters more here than in South Bali, and what to do before you board the boat so you don't arrive at Toyapakeh port without a working map.
Does eSIM Work in Nusa Penida?
Yes — but with more variation than anywhere else in the Bali area. Nusa Penida has been rapidly developing its mobile infrastructure over the past two years, and Telkomsel now provides reliable 4G across the main tourist corridor. The problem is that "main tourist corridor" covers about half the island. The remote southeastern viewpoints — Atuh Beach, Diamond Beach, Tree House — are genuinely difficult to reach and have minimal to no signal.
The other variable is which network your eSIM runs on. XL's coverage on Nusa Penida is noticeably weaker than Telkomsel, particularly outside Toyapakeh and the main road between Kelingking and Broken Beach. BaliSIM runs on Telkomsel, which consistently provides the strongest coverage across Nusa Penida's tourist areas.

Why Connectivity on Nusa Penida Is Different from Bali
Nusa Penida has no traffic lights, no Grab, limited ATMs, and roads that range from rough to genuinely dangerous on a scooter. Navigation is not optional — it's survival. The island's main viewpoints are connected by roads that don't always match what Google Maps shows, and getting lost here means finding yourself on a dirt track heading toward a cliff with no signal to call for help.
There's also a practical sequence issue that catches many travelers off guard: the fast boat from Sanur or Padang Bai arrives at Toyapakeh or Crystal Bay port, and the scooter rental drivers meet you immediately at the dock. Within minutes of landing, you need to navigate to your accommodation. If you haven't sorted your eSIM before boarding the boat, you're navigating a new island with no map and no data.
The solution is straightforward: install your BaliSIM eSIM in Bali before the crossing, download Google Maps offline for all of Nusa Penida while you still have Bali's strong 4G, and arrive at Toyapakeh port already oriented. The whole setup takes less than five minutes in your Sanur hotel the morning of departure.
Coverage Across Nusa Penida's Main Areas
Toyapakeh (main ferry port, north coast)
The strongest coverage on the island. This is where most travelers arrive, where the main scooter rental operators are based, and where most accommodation is concentrated. 4G on Telkomsel is consistent here throughout the day. This is also your last reliable opportunity to download offline maps and confirm your accommodation location before heading inland.
Kelingking Beach area
Consistently good 4G on Telkomsel. The viewpoint — one of the most photographed spots in Indonesia — has enough tower coverage for uploads, WhatsApp, and Maps. The clifftop area directly above the T-Rex-shaped peninsula has reliable signal. The beach itself (accessed by a very steep trail) has weaker signal.
Broken Beach & Angel's Billabong
Good 4G on Telkomsel across the viewpoint areas. Both sites are close together on the northwestern coast and fall within solid coverage range. These are among the easiest Nusa Penida destinations from a connectivity standpoint.
Crystal Bay
More variable. Signal at the bay itself ranges from moderate to weak depending on conditions and how many people are connected simultaneously. During peak season (July–August), tower congestion at Crystal Bay can slow speeds significantly. This is a popular manta ray snorkeling site and dive base — dozens of operators and tourists are all trying to use the same limited tower capacity. Download what you need before arriving.
Atuh Beach & Diamond Beach (southeast)
The southeastern coast of Nusa Penida is where the island's most dramatic landscapes are — and where coverage effectively ends. Atuh and Diamond Beach have minimal to no reliable signal on any network. The roads to reach them are long, poorly maintained, and infrequently travelled. Download offline maps and save your accommodation's GPS pin before heading to this part of the island.
Tree House & remote interior
No coverage. This area requires a guide, a reliable scooter, and fully offline navigation. Treat it the same way you would treat a remote trekking destination — everything you need must be on your phone before you leave Toyapakeh.
If you're planning a trip to Nusa Penida, check the latest Klungkung weather forecast before you travel. You'll find today's temperature, rainfall probability, wind conditions, and local weather updates to help you choose the best time for snorkeling, island tours, and fast boat crossings.
BaliSIM vs Buying a SIM Card on Nusa Penida
There are no major carrier stores on Nusa Penida. The island has a few small phone repair shops in Toyapakeh that sometimes sell physical SIM cards, but tourist registration is inconsistent and stock is unreliable. If you're planning to buy a SIM after you arrive, you're gambling on whether the right shop is open and has what you need — before you've even worked out how to get to your accommodation.
BaliSIM removes that problem entirely. Buy before you leave Bali, install the QR code at your Sanur or Padang Bai accommodation, and board the fast boat already connected.
| Feature | BaliSIM eSIM | Local SIM / Nusa Penida |
|---|---|---|
| Install before crossing | Yes — in Bali | Not available |
| Availability on the island | Already installed | Very limited, inconsistent |
| Keep home number active | Yes (dual SIM) | Usually no |
| Works across Bali too | Yes — same plan | Yes |
| English support | 24/7 via WhatsApp | Unlikely on the island |
Getting Around Nusa Penida: What You Actually Need Data For
Transport on Nusa Penida is almost entirely by scooter — either self-driven or with a hired driver. There are no Grab or Gojek drivers operating here; the ride-hailing app ecosystem doesn't function on the island. Navigation is entirely on you.
Google Maps offline is the single most important tool on Nusa Penida. The roads between viewpoints are complex, poorly signposted, and don't always match digital maps accurately. Experienced travelers download offline Maps before the boat crossing, then navigate entirely on GPS without needing live data. The GPS positioning works even without signal — only the map tile downloads require data, and you do that in advance.
Your BaliSIM Indonesian number is still useful on Nusa Penida for WhatsApp communication with your accommodation, confirming snorkel trip pickups, and messaging your boat operator for the return crossing. Most Nusa Penida businesses run entirely on WhatsApp.
The Fast Boat Crossing: What Happens to Your Signal
Most Nusa Penida crossings depart from Sanur Beach (multiple operators, 40 minutes) or Padang Bai (slightly longer, less crowded). Signal on both the Bali side and the Nusa Penida side is strong. Mid-crossing over the Badung Strait, signal drops for about 10–15 minutes.
Use the time in Sanur or Padang Bai before boarding to download your offline maps if you haven't already. The moment you dock at Toyapakeh, you'll want navigation ready. The scooter rental people approach immediately — having your accommodation pinned offline means you can hand your phone to the driver and go.
How to Set Up BaliSIM Before Your Nusa Penida Trip
The process takes under two minutes and should be done in Bali before you head to the boat departure point.
After purchasing your BaliSIM plan, a QR code arrives in your email. Open your phone's Settings, go to Mobile Data or Cellular, select Add eSIM, and scan the code. Set BaliSIM as your data SIM and leave your home SIM active for calls and messages. Then, while you still have strong Bali 4G, open Google Maps, search "Nusa Penida," and download the offline map for the entire island.
By the time your fast boat docks at Toyapakeh, you have working data via your BaliSIM eSIM, an offline map of the whole island loaded, and your accommodation's GPS pin saved. Everything that could go wrong on arrival is already handled.

Frequently Asked Questions
Does eSIM work well in Nusa Penida?
Yes, in the main tourist areas. Toyapakeh port, Kelingking Beach, Broken Beach, and Angel's Billabong all have reliable Telkomsel 4G. Crystal Bay is more variable due to tower congestion during peak hours. The southeastern coast — Atuh Beach, Diamond Beach, Tree House — has minimal to no signal. Download Google Maps offline for the entire island before boarding the fast boat from Bali. GPS positioning works without signal; you just need the map tiles downloaded in advance.
Should I download offline maps before crossing to Nusa Penida?
Yes — this is not optional. Nusa Penida's roads are complex, poorly signposted, and sometimes don't match digital maps accurately. Without offline maps, you're navigating blind at a destination where getting lost can mean riding to a cliff edge on a rough road with no signal to call for help. Download Google Maps offline for all of Nusa Penida while you're still in Sanur or Padang Bai — it takes about 2 minutes on Bali's 4G and uses roughly 200MB of storage. Your BaliSIM eSIM handles the data for the download; GPS navigation itself uses no data.
Can I use Grab or Gojek on Nusa Penida?
No. Grab and Gojek do not operate on Nusa Penida. Transport is by scooter rental (self-drive or with a local driver), and drivers are arranged directly at the port or through your accommodation via WhatsApp. Your BaliSIM Indonesian number is useful for these WhatsApp arrangements — accommodation hosts, scooter rental operators, and day trip organizers all communicate primarily via WhatsApp.
How much data do I need for Nusa Penida?
Less than you'd expect, because you'll be offline for large parts of the trip. A typical 2–3 night Nusa Penida stay uses 2–4GB of mobile data — primarily WhatsApp communication, navigation at coverage spots, and social media browsing at your accommodation. If you're staying in Bali before and after, your overall Bali trip data usage is the bigger number. See our Bali data usage guide for the full trip estimate.
Are there ATMs on Nusa Penida?
There are a small number of ATMs near Toyapakeh, but they frequently run out of cash on weekends and during peak season. The practical advice: withdraw cash in Bali before crossing. Carry more IDR than you think you need — many smaller warungs and some accommodation providers on the island are still cash-only, and QRIS acceptance is less universal here than in South Bali. This is one of the reasons having a working eSIM from the moment you land matters: you can at least confirm your accommodation has availability before you realize you need more cash.
Will my eSIM work back in Bali after Nusa Penida?
Yes — the same BaliSIM plan covers all of Bali seamlessly. There's no plan change, no reconnection step, and no additional cost for moving between Bali and Nusa Penida. The moment your fast boat approaches the Sanur or Padang Bai shoreline on the return crossing, your eSIM reconnects to Bali's strong 4G automatically. For coverage across all Indonesian islands on a single plan, see our Indonesia eSIM coverage guide.
Conclusion
Nusa Penida has some of the most spectacular scenery in all of Indonesia, and some of the most variable mobile coverage in the Bali area. The two facts are related — the island's remoteness is part of what makes it extraordinary, and the infrastructure gaps are a natural consequence.
For most travelers, the practical answer is simple: get your BaliSIM eSIM sorted in Bali, download offline maps before the boat crossing, carry cash from a Bali ATM, and arrive at Toyapakeh already oriented. The areas with coverage — Toyapakeh, Kelingking, Broken Beach — give you everything you need for navigation and communication. The areas without coverage — Atuh, Diamond Beach, the remote southeast — are the places where you'll be too busy looking at the view to notice your phone has no bars anyway.
