For Gili Trawangan, Gili Meno and Gili Air, we recommend an eSIM that includes Telkomsel. Reception varies by island, accommodation and position, especially on boat crossings. Choose the network first, then compare the allowance and price for your whole Indonesia trip.
We sell eSIMs, so read this knowing we're biased. The Telkomsel point isn't a sales line though, it's geography. Below is a carrier-by-carrier look at what actually reaches each of the three islands, which providers connect to which network, and an honest set of picks at the end.
The short answer for the Gili Islands
- Broadest listed carrier choice: Travelsim Asia (all three operator groups); Holafly also lists Telkomsel + XL Axiata
- Best overall pick: Travelsim Asia — Telkomsel + XL like Holafly, plus Indosat/Smartfren; lowest prices at 1 GB, 5 GB, 20 GB and 50 GB, no app
- Best if you want unlimited: Holafly — shared Telkomsel and XL access, about $4/day
- Budget alternative with Telkomsel: Nomad — $18 / 5 days soft-unlimited
- No confirmed Telkomsel for the Gilis: Ubigi

Why the Gili Islands are a coverage test, not a price test
On Bali, almost any eSIM works, so people choose on price. The Gilis flip that. These three islands sit off the northwest coast of Lombok, roughly 30 to 45 minutes by fast boat from Bangsal harbour and a couple of hours from Bali. Mobile reception varies by carrier and location, so check with your accommodation rather than assuming a plan that works well in Bali will work equally well on every island.
That makes the Gilis one of the few places where the network behind your eSIM changes the trip. Book a boat transfer, message a dive school, or check a return schedule, and you need service at the harbour and on the island. Telkomsel holds that signal best. The gap widens on Gili Meno, the quietest and least developed of the three, where weaker networks that limp along on Trawangan can disappear entirely.
Carrier coverage across the three Gilis
Reception on each island depends on the network your provider supports and local conditions. Here is how the five listed Indonesian carrier brands compare across Gili Trawangan (the largest and most developed), Gili Air (the middle option), and Gili Meno (the smallest and quietest).
| Network | Gili Trawangan | Gili Air | Gili Meno |
|---|---|---|---|
| Telkomsel | Strong | Strong | Best available |
| XL Axiata | Good | Good | Patchy |
| Indosat Ooredoo | Usable in spots | Weak | Weak to none |
| 3 (Hutchison) | Weak | Weak | None to speak of |
| Smartfren | Weak | Weak | Poor |
Reception varies by where you stand on the island, conditions on the crossing and network load. We recommend Telkomsel access for the Gilis, but save essential details before leaving a reliable connection.
The Gili Meno rule. If your itinerary includes Meno, Telkomsel stops being a nice-to-have. Trawangan has enough tourist infrastructure that XL Axiata holds up well and even weaker networks manage something. Meno is where that margin runs out. A Telkomsel-backed eSIM is the difference between a working map on Meno and hunting for a bar behind the dive shop.
Which providers carry Telkomsel
Coverage on the Gilis comes down to one question you can answer before you pay: does the provider name Telkomsel among its Indonesian networks? Five list Telkomsel; Ubigi lists Indosat.
| Provider | Telkomsel? | Networks | Setup / management | 5 GB price |
|---|---|---|---|---|
| Travelsim Asia | ✓ Yes | Telkomsel + XL + Indosat + Smartfren | Email; no account for balance or top-ups | $10.99 / 30 days |
| Holafly | ✓ Yes | Telkomsel + XL Axiata | App optional; web access available | N/A — unlimited only |
| Nomad | ✓ Yes | Telkomsel | QR or app; account for management | $12.00 / 30 days |
| Saily | Telkomsel listed | Telkomsel listed | App-based setup and management | $13.99 / 30 days |
| Airalo | ✓ Yes | Indosat Ooredoo + Telkomsel | QR or app; account for management | $13.50 / 30 days |
| Ubigi | ✗ No | Indosat | QR or app; account for management | N/A at 5 GB |
Comparison prices and provider network listings: 23 October 2026. Always verify on the provider's site before buying. Travelsim Asia is our own product.
Travelsim Asia and Holafly are both providers in this comparison pairing Telkomsel with XL Axiata, and Travelsim Asia adds Indosat and Smartfren on top , giving you other supported networks to try if reception is poor. The full network sets differ, and shared carrier names do not guarantee identical signal. Their plan models also differ: Travelsim Asia sells fixed-data plans at full speed from $3.99, Holafly sells unlimited at about $4/day. Nomad also carries Telkomsel.
The picks for the Gili Islands
Five providers list Telkomsel. Here is when each one is the right call, including where a competitor beats us.
Travelsim Asia — best overall for most Gili trips
Good for: travelers who want Telkomsel access plus other supported networks, with no separate app to install. We connect to all three Indonesian operator groups, Telkomsel, Indosat and XLSmart through XL/Smartfren, on fixed plans with no daily allowance throttle. Prices are the lowest among the providers compared here at 1 GB ($3.99), 5 GB ($10.99), 20 GB ($27.99), and 50 GB ($36.99). The eSIM arrives by email and installs straight from the email, with no app and no account, and top-ups happen through a web portal, useful when a two-day Gili stop turns into four. Less ideal for: travelers who specifically want unlimited data, which we don't sell. This is our product, so weigh the bias.
Holafly — shared Telkomsel and XL, with unlimited data
Good for: travelers who want unlimited data on the same Telkomsel + XL Axiata coverage and would rather not track gigabytes. If you plan to stream on the beach or video-call home every evening from Gili Air, Holafly's unlimited allowance avoids a fixed total, but fair-use rules can still reduce speed. Less ideal for: anyone counting cost. At about $4/day, a week runs $27.50, more than double what a Travelsim Asia 5 GB plan covers comfortably for the same trip at $10.99. Holafly also caps hotspot sharing at 1 GB/day, so it earns its price only when unlimited phone data is genuinely worth the premium to you.
Nomad — the budget Telkomsel alternative
Good for: travelers who want Telkomsel at a low price, especially on the soft-unlimited tiers at $18 / 5 days and $33 / 10 days, the lowest five- and ten-day unlimited totals in this comparison. A 5-day Gili and Lombok combo fits the $18 plan well. Less ideal for: heavy data users who hit Nomad's roughly 2 GB/day cap, after which speeds drop to 1 or 2 Mbps depending on the plan. Allow more high-speed data if you plan to upload large files or make video calls. Nomad lists Telkomsel, which we recommend for the Gilis; reception varies by location.
Airalo and Saily list Telkomsel; Ubigi lists Indosat
Honest steer: Airalo lists Telkomsel alongside Indosat Ooredoo, so it is a viable Gili option. Ubigi lists Indosat alone; Saily lists Telkomsel and can be considered for the Gilis. Check usable signal at your specific Gili Meno accommodation. Travelsim Asia adds XL/Smartfren to Telkomsel and Indosat, and costs less than Airalo at every matching fixed-data size. Choose Airalo if its unlimited or regional plan better fits your trip.
Gili-specific things worth knowing
- Boat transfers run on messages, not timetables. Public boats from Bangsal and fast boats from Bali (Serangan, Padang Bai, Amed) confirm times by WhatsApp and change with the weather. You want reliable signal at the harbour and on the island to rebook when a crossing shifts. This is another point for Telkomsel-backed coverage, which holds furthest over the water.
- There are no cars or scooters on the Gilis. You get around on foot, by bicycle, or by cidomo pony cart. Live turn-by-turn navigation matters far less here than on Lombok, so you'll use less map data, but you'll still lean on WhatsApp and booking sites that need a connection.
- WhatsApp runs the dive schools and homestays. Dive centres, freediving schools, homestay hosts, and boat captains all coordinate over WhatsApp. Voice and video calls work well on Telkomsel. Check that your plan doesn't throttle to a speed that breaks a call before you rely on it to confirm a dive.
- WiFi is decent on Trawangan and thin on Meno. Gili Trawangan's cafés and dive shops have usable WiFi you can offload heavy tasks onto. Gili Meno has far less, so your eSIM becomes the primary connection rather than a backup. Plan a little more data if Meno is on the list.
- Snorkelling and diving mean long stretches off your phone. Much of a Gili day is spent in the water, which keeps data use low. Most travelers need less data here than a Bali city stay, so a small plan with easy top-up beats overbuying.
How much data do you need for the Gili Islands?
A Gili trip is usually light on data. Time in the water, no scooter navigation, and decent WiFi on Trawangan all keep usage down. The main drivers are WhatsApp, booking and transfer sites, and social media between snorkel sessions.
| Trip style | Daily usage | Recommended plan |
|---|---|---|
| Day trip or overnight, light use | 200–400 MB | 1 GB ($3.99) |
| 2–4 days, WhatsApp, maps, social | 400–700 MB | 3 GB ($7.99) |
| A week across the Gilis and Lombok | 700 MB–1.5 GB | 5 GB ($10.99) |
| Heavy social, streaming, hotspot | 2 GB+ | 10 GB ($16.99) |
Most Gili travelers do fine on 3 to 5 GB. If the Gilis are part of a longer Lombok trip, size for the whole route and keep the top-up portal handy. Our Indonesia data guide breaks usage down app by app.
eSIM vs a local SIM for the Gilis
Arrange your data before crossing to the Gili Islands. If you buy a local SIM or eSIM in Bali or Lombok, ask the operator to register your foreign phone for tourist use. Travelsim Asia’s roaming eSIM does not require Indonesian IMEI registration.
For a short island stay, buying and installing an eSIM before you fly is the low-friction choice, as long as it carries Telkomsel. Our buy-and-install guide walks through setup on iPhone and Android.
The bottom line
For the Gili Islands, we recommend Telkomsel access and checking reception with your accommodation, especially on Meno. Download maps and tickets before the crossing: a listed network does not promise service on the boat or at every beach.
Travelsim Asia and Holafly both list Telkomsel plus XL Axiata (Travelsim Asia also lists Indosat and Smartfren); Airalo lists Telkomsel too. Travelsim Asia offers fixed data from $3.99 with no app, Holafly offers unlimited at about $4/day, and Airalo offers fixed, unlimited and regional plans. Nomad is the budget Telkomsel option. Whatever you choose, check the Telkomsel line before you pay, and compare Airalo on price and plan type; Saily also lists Telkomsel, while Ubigi lists Indosat; check that either plan meets your route's needs.
