Short answer
The best eSIM for Sulawesi is Telkomsel Indonesia Nationwide. Coverage is excellent in Makassar, reliable throughout Toraja, and stronger than other networks across most of Wakatobi. One eSIM covers your entire Indonesia trip, including Bali, Java, Lombok, and Sulawesi.
Planning a trip to Sulawesi and wondering whether you'll have internet access in places like Makassar, Tana Toraja, or Wakatobi? The answer depends entirely on where you're going. Makassar has some of the strongest mobile coverage in eastern Indonesia, Toraja is surprisingly well-connected for a mountain destination, while Wakatobi's remote islands require a network with the widest coverage footprint.
This guide covers the best eSIM for Sulawesi, network coverage in Makassar, Toraja, and Wakatobi, how reliable mobile data is for travel, diving, and remote work, and which eSIM plan makes the most sense if Sulawesi is only one stop on a larger Indonesia trip.
Traveler reality: Most international visitors don't travel to just one place in Sulawesi. A typical itinerary starts in Makassar, continues to Tana Toraja via the mountain road through Parepare and Enrekang, then extends to Manado, Bunaken, or Wakatobi. Mobile coverage changes significantly throughout that journey, which is why network choice matters more in Sulawesi than it does in Bali or Jakarta.
Why Sulawesi Requires a Different eSIM Strategy Than Bali
Bali is compact and heavily developed. Sulawesi is enormous. Distances between destinations are much larger, terrain is more mountainous, and many travelers combine cities, highland regions, islands, and marine parks in a single trip.
That means coverage matters far more than raw speed. A network that works perfectly in Makassar may struggle on remote roads through Toraja or on smaller islands in Wakatobi.
This is why most experienced Indonesia travelers choose Telkomsel when visiting Sulawesi. It has the broadest infrastructure footprint across eastern Indonesia and remains the most reliable option once you leave major urban centers.
Quick tip: If you're visiting Bali before Sulawesi, activate your BaliSIM eSIM before leaving Bali. Your connection will continue working automatically when you land in Makassar.
eSIM vs Physical SIM Card in Sulawesi
You can buy physical tourist SIM cards at Sultan Hasanuddin Airport in Makassar, but most travelers benefit more from arriving already connected. Booking Grab, confirming hotel reservations, contacting dive operators, and arranging transfers is easier when your phone works immediately after landing.
An eSIM also avoids Indonesian tourist SIM registration requirements and removes the need to search for a carrier store after a long flight.
If Sulawesi is part of a larger Indonesia itinerary, a single BaliSIM Nationwide plan works across Bali, Lombok, Java, Flores, Komodo, and Sulawesi without changing SIM cards. Read our complete Indonesia eSIM guide for a full breakdown.
Best eSIM Options for Sulawesi in 2026
1. Telkomsel eSIM — Best Overall for Sulawesi
Telkomsel is the strongest network throughout Sulawesi and the easiest recommendation for travelers. Coverage is excellent in Makassar, reliable across Tana Toraja, and generally stronger than competitors throughout remote regions and island destinations.
If your itinerary includes road trips, ferry travel, diving trips, mountain regions, or multiple cities, Telkomsel consistently delivers the most reliable experience.
Best for: Makassar, Toraja, Wakatobi, overland travel, island hopping, remote destinations
Coverage: Strongest overall network in Sulawesi
Travelers: Most international visitors
2. XL eSIM — Good in Cities, Weaker Outside
XL performs well in Makassar and larger urban areas but loses coverage more quickly outside city centers. For travelers staying exclusively in Makassar, XL can be sufficient. For Toraja, Wakatobi, or extended travel through Sulawesi, Telkomsel remains the safer choice.
Best for: City-focused trips
Not ideal for: Toraja, Wakatobi, remote roads, island travel

What Data Plan Do You Need for Sulawesi?
Makassar city trip (3–5 days)
Maps, Grab, WhatsApp, restaurant bookings, and social media usage typically fit comfortably within a 10–15 GB plan.
Makassar + Toraja itinerary (5–8 days)
You'll use significantly more navigation data while traveling between destinations. A 15–20 GB plan is recommended.
Sulawesi explorer route (10–14 days)
Combining Makassar, Toraja, Manado, Bunaken, or Wakatobi is best served by a larger Nationwide plan.
Diving trip in Wakatobi
Most resorts provide Wi-Fi, but mobile data remains useful for transfers, flight changes, messaging, and backup connectivity. Telkomsel offers the best chance of staying connected between islands.
Indonesia multi-island trip
If Sulawesi is only one stop alongside Bali, Lombok, Java, or Flores, choose a Nationwide plan and use a single eSIM for the entire journey.

Frequently Asked Questions
Does eSIM work in Tana Toraja?
Yes. Telkomsel coverage in Rantepao and Makale is generally strong and reliable for maps, WhatsApp, ride bookings, hotel reservations, and social media. Most hotels, cafés, and tourist sites in Toraja have usable mobile coverage.
If you're visiting traditional villages or remote viewpoints, download offline Google Maps before leaving town.
Is internet available in Wakatobi?
Yes, but expectations should be different from Bali or Jakarta. Wangi-Wangi generally has reliable mobile coverage, while smaller islands and boat routes may experience weaker connectivity.
Most dive resorts provide Wi-Fi, but speeds vary depending on weather, infrastructure, and island location.
Download boarding passes, dive itineraries, and maps before traveling between islands.
Which network is best for Sulawesi: Telkomsel or XL?
For city-only trips in Makassar or Manado, both networks perform well. However, travelers heading to Toraja, Bunaken, Wakatobi, or multiple destinations across Sulawesi generally benefit from Telkomsel's broader coverage footprint.
This becomes particularly noticeable during long road trips, ferry transfers, and travel through rural areas where Telkomsel typically maintains coverage longer than competing networks.
For a detailed comparison, see our Telkomsel vs XL guide.
Can I work remotely from Sulawesi?
Yes, particularly in Makassar and Manado. Both cities have modern hotels, coworking spaces, reliable Wi-Fi, and strong mobile networks suitable for Zoom, Google Meet, and cloud-based work.
Toraja supports light remote work and video calls, while Wakatobi should be viewed primarily as a diving destination where internet reliability varies between resorts.
Do I need a separate eSIM for Wakatobi?
No. A Telkomsel Indonesia Nationwide eSIM covers Wakatobi alongside the rest of Indonesia. There is no need to purchase a separate local SIM card after arriving.
For most travelers, one Nationwide plan is the simplest option because it works continuously from Bali, Jakarta, Makassar, or Manado all the way through to Wakatobi.
Conclusion
Sulawesi rewards travelers who venture beyond Indonesia's most visited destinations. From Makassar's waterfront and seafood markets to Toraja's mountain culture and Wakatobi's world-class diving, the island offers experiences that feel very different from Bali.
Those same distances and remote destinations are exactly why choosing the right network matters. While nearly any network works in central Makassar, travelers heading to Rantepao, Bunaken, Kendari, Wangi-Wangi, or Tomia benefit from the wider footprint of Telkomsel.
A single BaliSIM Nationwide eSIM keeps you connected throughout the journey without changing SIM cards between islands, airports, ferries, and domestic flights. Install it before departure, arrive connected, and focus on exploring Sulawesi rather than searching for a mobile signal.
