Is There Reliable 4G Data in Siargao? Smart vs Globe Signal Tested
Thai Simcard 路
馃嚨馃嚟eSIM for Philippinesfrom $1.99Yes, there is usable 4G data across Siargao, but coverage splits sharply between providers. Smart offers the most consistent reception around General Luna, Cloud 9, and the northern surf spots like Pacifico, while Globe performs well in town but turns patchy along rural coastal roads.
Siargao is an island where neither major Philippine carrier holds complete dominance. Smart and Globe both invested heavily in local infrastructure after Typhoon Odette, but their coverage is distributed unevenly across different barangays. While the main strip between General Luna and Cloud 9 enjoys solid connectivity on both networks, heading out to remote breaks or quieter villages quickly exposes signal gaps.
Local power grid stability also plays a major role in mobile internet quality. When a barangay experiences a brownout, cell towers rely on backup power systems that can drop out after several hours. Having access to both Smart and Globe gives you a working backup when one network's local tower loses power or becomes congested.
Siargao network coverage by area
Mobile reception changes depending on whether you are staying in the bustling tourist corridor or renting a scooter to explore the northern beaches.
| Area or Landmark | Smart Reception | Globe Reception | Connectivity Notes |
|---|---|---|---|
| General Luna & Cloud 9 | Good | Generally good | Both work well; speeds can slow during evening peak surf season |
| Dapa (Ferry Port) | Good | Usable | Smart coverage is good while Globe is usable |
| Pacifico & Burgos (North) | Stronger side | Patchy | Smart holds signal along coastal roads; Globe fades frequently |
| Magpupungko Rock Pools (Pilar) | Patchy | Patchy | Patchy coverage on both networks |
| Del Carmen & Sugba Lagoon | Weak | Weak | Signal drops quickly once boats travel inside mangrove channels |
| Island Hopping (Guyam, Daku, Naked) | Usable | Usable | Line-of-sight signal carries across the water from General Luna |
During high surf season between August and November, network towers along General Luna face heavy congestion. Even with full signal bars, evening bandwidth can slow down when cafes, resorts, and tourists upload video clips and run calls simultaneously.
What Thai Simcard uses here
Thai Simcard connects to both SMART 5G and Globe 5G networks in the Philippines. This dual-network access allows your phone to switch between carriers depending on which barangay you visit, avoiding the risk of getting stuck without signal if a local cell site goes down.
Available plans for the Philippines eSIM include:
- 1GB / 7 days: US$2.49
- 3GB / 15 days: US$4.49
- 3GB / 30 days: US$4.99
- 5GB / 30 days: US$6.49
- 10GB / 30 days: US$11.49
- 20GB / 30 days: US$19.99
- 50GB / 30 days: US$44.49
Because Thai Simcard supports both Smart and Globe, you can manually select the stronger network in your device settings if you head north to Pacifico or if a power cut knocks out Globe towers in your part of General Luna.
Practical connectivity tips for Siargao
- Expect routine brownouts: Power cuts occur regularly across Siargao, particularly during bad weather. Carry a fully charged portable power bank. Backup tower batteries can drain during extended outages, which may knock out service on one or both networks.
- Book everything through chat apps: Surf instructors, boat captains, and habal-habal motorbike riders coordinate almost entirely through Facebook Messenger and WhatsApp. Real-time data is essential because confirmations frequently arrive just an hour before departure.
- Keep data active for GCash: Many cafes, surf shacks, and drivers accept GCash, but processing the transfer requires an active mobile data connection at the register. Always carry backup Philippine peso cash because ATMs in General Luna frequently run out of money in peak season.
- Cache your maps offline: Download offline Google Maps for Siargao before leaving your resort. Certain rural and inland areas have weak or patchy signal where navigation apps can struggle without offline data.

Frequently asked questions
Which network is better for surfing spots in northern Siargao?+
Smart generally provides stronger, more dependable coverage around Pacifico and Burgos in the north, whereas Globe coverage is patchy in these northern areas.
Is there mobile signal at Sugba Lagoon?+
Signal is very weak or nonexistent inside Sugba Lagoon. Both Smart and Globe fade as your boat moves deep into the Del Carmen mangrove channels.
Do power outages shut down phone internet on Siargao?+
Power cuts can knock out mobile data. Cellular towers have battery backups, but prolonged brownouts cause batteries to drain, disabling towers for one or both carriers until electricity is restored.
Can I switch between Smart and Globe on the same eSIM?+
Yes. If your eSIM includes access to both networks, you can go into your phone's cellular settings, turn off automatic network selection, and choose the alternative carrier if your current connection drops.
