Siargao is a two-network island, and the two networks don't agree on where to be good. Smart and Globe both cover the island, but their strength splits by barangay: one carries the General Luna strip, the other holds up better past Pacifico, and a brownout can drop one network's towers while the other keeps working. We recommend access to both so you have another network to try if reception is poor. Check the networks listed on the plan before buying.
We sell eSIMs, so read this knowing we're biased. But the Siargao problem is structural: almost every travel eSIM locks you to either Smart or Globe, and on this island you want both. Below is where each network works, which providers connect to which, and honest picks for surf season.
The short answer for Siargao
- The Siargao reality: Smart and Globe split the island. Neither wins everywhere, and outages can affect either or both networks.
- Best overall pick: Travelsim Asia, a provider on both Smart and Globe, cheapest 30-day 10 GB ($14.99), no app
- Best if you want unlimited: Holafly, Globe only, an option for trips based around General Luna
- Best big-data plan: Nomad, 20 GB / 45 days at $27.00, Globe only
- Other network options: Airalo (Smart), Ubigi (DITO + Smart), Saily (network undisclosed)

Why Siargao is a two-network island
Most coverage-problem islands have one answer. Raja Ampat is Telkomsel or nothing, and the Gilis lean hard on one Indonesian carrier. Siargao is different: Smart and Globe both invested here, especially in the rebuild after typhoon Odette, but they invested in different places. The tourist economy runs down the east coast from General Luna to Cloud 9, and coverage there is decent on both networks most days. Ride north to Pacifico and Burgos, cross to Dapa for the ferry, or head into the mangroves at Del Carmen for Sugba Lagoon, and the two networks stop being interchangeable.
Then there's the power grid. Siargao's electricity flickers, and when a barangay browns out, cell sites on backup batteries start dropping. Either network can be affected, and an outage may reach both. We recommend access to Smart and Globe so you can try the other network when one is unavailable, while keeping essential details offline.
Where each network works on Siargao
A realistic picture by area, from the airport to the day trips.
Siargao network coverage
| Area | Smart | Globe |
|---|---|---|
| General Luna and Cloud 9 | Good | Generally good; check reception at your accommodation |
| Dapa (ferry port) | Good | Usable |
| Pacifico, Burgos, the north | Usually the stronger side | Patchy |
| Del Carmen and Sugba Lagoon | Weak, fades in the lagoon | Weak, fades in the lagoon |
| Magpupungko (Pilar) | Patchy | Patchy |
| Island hopping (Daku, Guyam, Naked) | Signal from the GL coast, usable | Signal from the GL coast, usable |

The brownout rule. Power cuts can affect either mobile network, and sometimes both. An eSIM that includes Smart and Globe gives you another supported network to try if one is unavailable; it cannot guarantee service during an outage. Keep essential bookings and maps offline.
Which providers give you which network
Every major travel eSIM answers the Smart-or-Globe question differently, and only one refuses to choose. Prices shown at 10 GB, the size most two-week surf trips use.

Comparison prices and provider network listings: 23 October 2026; linked in the Sources section below. Travelsim Asia is our own product.
Travelsim Asia is the only provider in this comparison explicitly listing both Smart and Globe, with the lowest-priced 1 GB, 5 GB and 30-day 10 GB Philippines plans, no app and no account. We recommend that network choice for Siargao: if reception is poor where you are staying, you have another supported network to try.
The picks for Siargao
Here is when each provider is the right call, including where a competitor beats us.
Travelsim Asia: best overall for Siargao
Good for:
anyone whose trip goes past the General Luna strip, and anyone who'd rather not think about Philippine network politics. You can try Smart or Globe if reception is poor as you move between the strip, the north and the ferry port. Cheapest 30-day 10 GB among the providers compared here at $14.99 / 30 days, cheapest 1 GB ($2.99) and 5 GB ($10.49) too, delivered by email with no app and no account, top-ups by web portal when the swell talks you into a second week.
Trade-offs:
unlimited data (we don't sell it) and 20 GB+ plans, where Nomad beats us. This is our product, so weigh the bias.
Holafly: unlimited on the Globe side
Good for:
travelers basing themselves on the General Luna strip who want unlimited data without watching a counter, streaming and video-calling from cafés and villas. Globe holds the strip well, and Holafly’s unlimited is subject to fair-use speed reductions; hotspot sharing is limited to 1 GB/day.
Trade-offs:
exploring the island. It's Globe-only, so the north coast and brownout days can leave it flat, and at roughly $4/day it costs several times a fixed plan. Hotspot sharing is capped at 1 GB/day, which matters if your villa WiFi dies and the laptop needs rescuing.
Nomad: the big-data pick, on Globe
Good for:
heavy users and long stays. Nomad's 20 GB / 45 days at $27.00 is the best big-data deal in this Philippines comparison, beating our 20 GB ($29.99 / 30 days) on both price and validity, and their 50 GB / 30 days at $45.00 has no equivalent from us.
Trade-offs:
the same reason as Holafly: it's Globe-only, with account-based management and QR installation outside the app. If your month on Siargao is mostly the strip, it's a strong pick. If it's the whole island, you're back to one-network roulette.
Airalo, Ubigi and Saily: alternatives without listed Smart + Globe access
Honest steer: Airalo lists Smart; Ubigi lists DITO and Smart. Neither lists Globe, so neither offers the Smart + Globe combination we recommend for Siargao. Ubigi does list a second operator, though that does not establish DITO reception at your accommodation. Both cost more than us at 10 GB for 30 days ($19.00 and $16.00 against $14.99). Saily does not disclose its Philippine network, so ask about coverage for your planned stops before buying.
Siargao things worth knowing
- Brownouts are routine, so charge accordingly. Power interruptions hit regularly, more in storm season. A power bank keeps your phone alive through them, and access to Smart and Globe gives you another network to try if one goes down. An outage can affect both.
- Everything books through Messenger and WhatsApp. Surf instructors, habal-habal drivers, island-hopping boats, villa hosts: it all runs on chat, Facebook Messenger above all. The Philippines is a Messenger country, and confirmations arrive an hour before, not a day before. You want working data, not café WiFi you left twenty minutes ago.
- GCash needs data to pay. Half of Siargao's shops and drivers take GCash, and it needs a connection at the moment of payment. Cash still rules the smaller sari-sari stores, and the island's ATMs run dry in high season, so carry both.
- Surf season strains the strip's towers. August to November brings the crowds to Cloud 9, and evening speeds in General Luna sag when every villa and café hits the network at once. Being on whichever network is less congested that evening is another quiet win for carrying both.
- Download before the day trips. Sugba Lagoon and the Magpupungko pools sit in the island's weakest coverage. Save offline maps, your booking confirmations, and the tide chart before the boat leaves. Surf and weather forecasts matter here in typhoon season, so check them in town, not from the lagoon.
- Island WiFi is better than it was, and still not something to rely on. Fiber reached General Luna, but outages track the power grid and village WiFi fades fast outside the strip. Treat your eSIM as the primary connection and WiFi as a bonus, which is the Philippines rule everywhere off the big cities.
How much data do you need for Siargao?
More than a city trip. WiFi can't be leaned on, Messenger runs your logistics, GCash runs your payments, and surf clips are heavy. Data discipline on Siargao is mostly about uploads: a few reels of Cloud 9 footage move more data than a week of maps and chat.
Data by trip style
| Trip style | Daily usage | Recommended plan |
|---|---|---|
| Long weekend, chat and maps | 300–600 MB | 3 GB ($6.99) |
| A week of surfing, light posting | 500 MB–1 GB | 5 GB ($10.49) for lighter use; 10 GB ($14.99) near 1 GB/day |
| Two weeks, daily clips and stories | ~1 GB+ | 20 GB (Travelsim Asia $29.99 / 30d or Nomad $27.00 / 45d); 14 GB+ needed |
| A month, remote work, heavy uploads | 1.5 GB+ | 50 GB starting allowance (Nomad $45.00 / 30d); 45 GB+ needed, with more data if use exceeds 50 GB |
A light surf trip can fit 5 to 10 GB, but daily video uploads or laptop work need more. At 1 GB a day, two weeks requires at least 14 GB; at 1.5 GB a day, a 30-day stay requires at least 45 GB. Use the table for your expected mobile use and keep the top-up portal handy. Our Philippines data guide breaks usage down app by app.
eSIM vs a local SIM for Siargao
You can buy a local Smart or Globe SIM in Siargao and follow the operator’s registration process. Local Philippine eSIMs also require registration. Travelsim Asia’s roaming eSIM arrives by email without a local SIM-registration step, so you can install it before flying to Sayak. You can keep your home number alongside it; your home carrier’s roaming terms still apply to calls and SMS.
Install before you fly and test it during your Manila or Cebu layover. Our buy-and-install guide walks through setup on iPhone and Android.

The bottom line
Siargao doesn't have a best network. It has two networks that divide the island between them and can both be affected when the power goes out. That turns the usual eSIM comparison upside down: the deciding feature isn't price or an app, it's whether you're forced to pick a side.
Travelsim Asia is the only provider in this comparison explicitly listing both Smart and Globe, with the lowest-priced 30-day 10 GB plan in this comparison at $14.99. Holafly is the unlimited pick if your trip lives on the General Luna strip, and Nomad wins big-data trips at 20 GB and up. Whichever way you go, know which network you're buying before you pay, because on Siargao that answer follows you to every break on the island.
