Which Network Actually Works Best in Flores?
Independent connectivity guides and traveler forum threads converge on the same answer: Telkomsel. It holds roughly the largest market share and the widest physical tower network in Indonesia, and — more relevantly for Flores — it’s the carrier most consistently reported as having usable signal outside Labuan Bajo town itself, including on stretches of the Trans-Flores Highway between Ruteng, Bajawa, and Ende where other networks can drop out entirely.
This doesn’t mean other carriers are useless. In Labuan Bajo town, Indosat and XL generally work fine for browsing and messaging. The gap shows up once you’re overland: on multi-day drives or in villages away from the coast, Telkomsel is the network most travelers report still having a signal on, even if it’s only 3G rather than 4G in some pockets.
Physical SIM Card vs eSIM: Which Should You Choose?
- Physical Telkomsel SIM, bought locally: the most reliable option, sold at the airport, at Telkomsel outlets in Labuan Bajo, and at many convenience stores. Requires passport registration (standard for all Indonesian SIMs), takes a few minutes, and gives you a real local number.
- International eSIM, bought before you fly: convenient — no physical swap, active before you land — but only as good as the local network it partners with. Some travelers report eSIM brands that work fine in Bali failing once they reach Flores or Raja Ampat, because the eSIM’s Indonesian partner isn’t Telkomsel.
- Dual approach: many travelers keep an eSIM as backup and buy a physical Telkomsel SIM on arrival specifically for the overland or boat portion of the trip, when reliable signal matters more.
If you’re booking an eSIM in advance, check the provider’s own coverage page or reviews specifically for “Flores” or “Nusa Tenggara Timur (NTT)” rather than just “Indonesia” — national-level marketing copy rarely distinguishes between Bali-level coverage and the much thinner network in eastern Indonesia.
Where Is Signal Reliable, and Where Does It Drop?
| Location | Typical signal | Notes |
|---|---|---|
| Labuan Bajo town | Good, 4G on most networks | Hotels and cafes also commonly offer WiFi |
| Komodo boat trips (day trips, liveaboards) | Patchy to none once away from the coast | Signal often returns near larger islands, drops in open water and remote anchorages |
| Ruteng, Bajawa, Ende (main towns) | Generally reliable, mainly Telkomsel | Other carriers work in town centers, less so on approach roads |
| Rural villages and trekking routes (Wae Rebo, remote highland stops) | Weak to none | Wae Rebo itself is commonly reported as having no signal at all |
| Kelimutu crater lakes area (Moni) | Workable in Moni village, weaker at the crater rim | Plan sunrise logistics assuming you may be offline for a few hours |
How Do I Buy a Local SIM Card in Flores?
- At Labuan Bajo airport or in town: Telkomsel counters and authorized dealers sell tourist SIM packages, typically pre-loaded with a data bundle.
- Bring your passport. Indonesian regulation requires SIM registration tied to an ID document — this applies to every carrier, not just Telkomsel.
- Ask for the tourist or traveler package specifically, since these usually bundle a data allowance sized for a 1 to 4 week trip rather than a monthly local plan.
- Top up as needed via the carrier’s app or at any convenience store carrying Telkomsel top-up vouchers, common throughout Labuan Bajo and larger overland towns.
Is There WiFi on Komodo Boats and in Remote Areas?
Assume no reliable WiFi once your boat leaves the harbor. Some higher-end liveaboards and phinisi charters advertise onboard WiFi via satellite or a signal booster, but coverage in open water between islands is inconsistent even on boats that offer it — treat any onboard WiFi as a bonus, not something to plan communication around. If staying reachable during a multi-day boat trip matters (family updates, work), tell your operator before booking so they can flag which boats in their fleet, if any, have a working satellite connection — see our Komodo phinisi charter guide page for cabin and boat comparisons.
On land, most guesthouses, hotels, and cafes in Labuan Bajo, Ruteng, Bajawa, and Ende offer WiFi, generally more consistent than mobile data in older buildings with thick walls. Rural homestays, including overnight stays at Wae Rebo, typically have none at all — part of what makes that stop feel genuinely remote rather than just quiet.
Can You Work Remotely From Flores?
Short bursts of connectivity, yes; a full remote workday relying on video calls, no — not outside Labuan Bajo town, and even there expect occasional drops during peak-usage hours or bad weather. Digital nomads working from Flores generally base themselves in Labuan Bajo for the reliable WiFi and Telkomsel coverage, treating any overland or boat leg as genuinely offline time rather than trying to stay connected throughout. If your trip needs guaranteed connectivity for part of it, plan the working days around your Labuan Bajo stay and treat the Trans-Flores and boat portions as a deliberate break instead of fighting for signal.
Power, Plugs and Other Connectivity Basics
Indonesia uses the European-style Type C and Type F plugs (two round pins), running at 220–230V. Travelers arriving from the US, UK, Australia, or most of Asia will need a plug adapter — pack one rather than assuming you can buy one easily outside Labuan Bajo’s main tourist strip, since hardware stores in smaller overland towns don’t reliably stock them. Power cuts are uncommon in Labuan Bajo itself but do happen occasionally in smaller villages and during heavy storms, so a power bank is worth carrying if you’re relying on your phone for photos and navigation on overland days.
For messaging apps specifically, WhatsApp is the default communication channel for tour operators, drivers, and boat crews across Flores — more so than email or phone calls for day-to-day coordination. Downloading offline maps (Google Maps offline areas, or a dedicated offline-maps app) before you lose signal is worth doing before any overland or boat day, since re-routing without a live connection is otherwise difficult on Flores’ winding mountain roads.
Frequently Asked Questions
Which SIM card works best for tourists visiting Flores?
Telkomsel is the most consistently recommended carrier across independent travel and connectivity guides, specifically because of its wider coverage outside Labuan Bajo town.
Do international eSIMs work well in Flores?
Only if they route through Telkomsel’s network. Some eSIM brands that work well in Bali have been reported by travelers as unreliable in Flores and Raja Ampat, so check the provider’s specific network partner for eastern Indonesia before buying, not just its general Indonesia coverage claim.
Is there internet access on Wae Rebo?
Generally no. Wae Rebo’s remote highland location is commonly reported as having no mobile signal, which is part of the appeal for travelers seeking a genuinely disconnected overnight stay.
Do I need to register my SIM card with my passport?
Yes — Indonesian regulations require SIM registration tied to an identity document for all carriers, including tourist SIM packages sold at the airport.
Will my phone work at all during a multi-day Komodo boat trip?
Expect intermittent signal near larger islands and none in open water or remote anchorages, unless your boat specifically has a satellite WiFi system — ask your operator before booking if staying reachable matters to your trip.
Planning Connectivity Around Your Itinerary
If staying reachable matters for part of your trip, tell Komodo Luxury when booking so they can flag which Labuan Bajo boat packages or overland routes have better connectivity, and which stretches — Wae Rebo, open-water boat days — are worth planning as offline time in advance.

Practical Tips for Staying Connected and Paying Your Way on Flores
Buy a Telkomsel prepaid SIM. It has the coverage the others do not once you leave town, and that is the whole decision for most visitors. Indosat and XL are fine if you are staying in Labuan Bajo and nowhere else. Kiosks at Komodo Airport and the shops along Jalan Soekarno-Hatta sell starter packs, though the official Telkomsel outlets register them fastest. Bring your passport — every new SIM activation in Indonesia requires it.
If you would rather use an eSIM, check that the plan actually runs on Telkomsel rather than simply saying “Indonesia”. Several brands default to a weaker network outside Bali, which you will not notice until you are three hours east of the harbour. An eSIM works well as a backup or for a short trip; a physical SIM performs noticeably better on the road.
Speeds are slower here than in Bali or Java. Expect 4G in the main towns and 3G or worse across much of the island. In Labuan Bajo itself, speeds average 10 to 20 Mbps on a good day — enough for a video call — with outages and slowdowns during storms and peak hours. On the liveaboards, in the park and in the rural villages there is effectively nothing, so download maps and anything you need offline before you leave.
On paying: carry cash for markets, ojek rides and homestays. Larger hotels, dive shops and some Labuan Bajo restaurants take cards, with surcharges and the occasional network failure. Power is the standard European two-pin, Type C or F, at 220V. The markets, Pasar Baru in Labuan Bajo included, take cash only. Small notes make bargaining easier and buying a snack possible.
More Questions Answered
Do I need an Indonesian SIM card in Flores?
Yes, you need an Indonesian SIM card if you want mobile data or to make local calls outside of WiFi areas. International roaming is expensive and unreliable in Flores. A local SIM provides better coverage, especially on overland routes or rural stretches where only Indonesian networks operate.
Where can I buy a SIM card in Labuan Bajo?
You can buy a SIM card in Labuan Bajo at the airport arrivals area, official Telkomsel and Indosat outlets, and numerous mobile shops along Jalan Soekarno-Hatta. The airport is fastest for immediate activation, but official outlets offer the most help with registration and data packages.
Is there good internet in Flores Indonesia?
Internet in Flores Indonesia is good in major towns like Labuan Bajo, with 4G available, but slows considerably in rural areas. The best speeds, averaging 10–20 Mbps, are in Labuan Bajo. Away from towns and in the Komodo islands, signal and speeds are often poor or absent.
Can I get an eSIM for Flores Island?
Yes, you can get an eSIM for Flores Island, but it only works well if your provider uses the Telkomsel network. Many global eSIM brands partner with weaker Indonesian networks. Order and activate your eSIM before arrival, and verify provider details for the Nusa Tenggara Timur region.
Can I use credit cards in Labuan Bajo?
Credit cards are accepted at most upmarket hotels, dive shops, and some restaurants in Labuan Bajo. However, power cuts and unreliable card terminals are common, and local markets operate cash-only. Always carry cash for transport, street food, and small purchases; ATMs are available in town.
What plug adapter for Indonesia and Flores?
Flores uses the same plug adapter as the rest of Indonesia: European two-pin (Type C or F) with 220V. Bring a universal adapter if your devices use a different standard. Power in hotels is usually stable, but bring a surge protector if you are charging sensitive electronics in rural areas.
