Do I need a SIM card on Koh Phangan?

Not strictly — hotel and cafe WiFi is widely available and covers most everyday needs. But a local data SIM gives you reliable connectivity on the move: navigating unfamiliar roads, looking up listings while out, messaging, and a backup if hotel WiFi is slow. For remote workers doing video calls, a good data SIM (used alongside a coworking space) is near-essential.

Where do I buy a SIM card on Koh Phangan?

The most convenient option is to buy at Koh Samui Airport before boarding the catamaran to Koh Phangan — carrier counters are in the arrival hall and have you connected before you step off the ferry. On the island, 7-Eleven stores and official AIS and True Move outlets in Thong Sala stock tourist SIM cards. You need your passport to register one.

Which carrier is best on Koh Phangan — AIS or True Move?

Both AIS and True Move provide 4G coverage in the island's main areas (Thong Sala, the south coast, west coast and Chaloklum). AIS has historically had the edge for island-wide coverage, but both are practical choices for the main beaches. Coverage weakens on the remote east coast and in the jungle interior regardless of carrier.

Can I use an eSIM on Koh Phangan?

Yes — if your phone supports eSIM, you can purchase and activate a Thai tourist eSIM online or at the airport and be connected without a physical card swap. Major Thai carriers (AIS, True Move) and many international eSIM providers offer Thailand plans. Check your phone's settings under 'SIM card' or 'Mobile data' to confirm compatibility before you rely on this option.

Is the internet fast enough for video calls on Koh Phangan?

In the main towns and the established coworking cafes (particularly in Sri Thanu, Ban Tai and Thong Sala), internet speeds are fast enough for reliable video calls. Hotel and guesthouse WiFi varies considerably — some is excellent, some is barely usable for streaming. For reliable video call sessions, the dedicated coworking spaces are the better environment. A good data SIM provides a fallback.

How much data do I need for a week on Koh Phangan?

It depends entirely on usage. Light users (messaging, occasional maps, casual social media) get by on a few gigabytes per week without issue. Remote workers who rely on mobile data for calls and uploads will run through a tourist package quickly and should buy the highest-data option available, prioritise WiFi for video calls, and keep mobile data for navigation and messaging. There is no hard rule — assess how you use data normally and buy accordingly.

Is there good WiFi at guesthouses and resorts on Koh Phangan?

WiFi is standard across the island's accommodation, but quality varies enormously. Larger resort hotels and coworking-friendly cafes in Sri Thanu and Thong Sala have fast, reliable connections. Smaller bungalow resorts and remote beach stays can have slow or intermittent WiFi. Check recent reviews specifically mentioning WiFi if a reliable connection is important to your stay.

Koh Phangan · Connectivity & Practicalities

SIM Card & Internet on Koh Phangan

Coworking café on Koh Phangan — the island has reliable internet at established cafes and coworking spaces

Staying connected on Koh Phangan is straightforward in the main areas: good 4G coverage across the south coast, west coast and the main towns, a dense network of cafes and guesthouses with WiFi, and Thai tourist SIM cards available at every 7-Eleven on the island. The key is to sort things out before heading to a remote beach, since coverage and access drop sharply once you leave the main roads.

Buying a SIM at Koh Samui Airport before the crossing is the smoothest approach — you step off the catamaran already connected. Once on the island, Thong Sala is the practical place to top up data, replace a SIM or find a store if you didn't sort it before arriving.

Buying a SIM card in Thailand

Thai law requires a passport to register a SIM card — carry yours when you go to buy. SIM cards are sold at all major Thai airports (Koh Samui Airport included) at carrier counters in the arrival hall, and throughout the island at 7-Eleven convenience stores, True Move and AIS outlets in Thong Sala, and some guesthouses that stock them for convenience. The process is quick: hand over your passport, choose a tourist data package, and you're connected within minutes of stepping off the ferry. Buying at Koh Samui airport before the crossing is the most convenient option — you board the catamaran already online.

Getting to Koh Phangan → AIS · True Move · 4G island-wide

Which carrier to choose

AIS and True Move (which now operates the former DTAC network) are the two main carriers covering Koh Phangan, both offering tourist SIM cards with data packages designed for short stays. AIS has historically had the strongest coverage across the island's main areas; True Move is competitive in the main towns and beaches. Both deliver 4G speeds in Thong Sala, Haad Rin, the west coast and Chaloklum — the areas where most visitors spend most of their time. The honest difference in daily use is small; the main thing is to choose a package with enough data for your trip length and usage pattern, since topping up on the island is possible but requires a convenience store.

Coverage across the island

4G coverage is reliable across the island's main areas: the south coast from Thong Sala to Haad Rin, the west-coast strip through Sri Thanu and Haad Yao, and the north coast around Chaloklum. Coverage weakens in the more remote corners — the east coast around Than Sadet and Haad Sadet, the inner jungle roads, and the boat-access bays like Bottle Beach and Haad Yuan where there's no road and no cell tower. If you're based in one of the main beach areas you'll have no meaningful issues; if you're heading to the island's remote east coast or off-grid accommodation, expect limited or no signal and plan accordingly.

eSIM — the traveller's alternative

If your phone supports eSIM (most modern smartphones from 2019 onwards do), an eSIM is an alternative to buying a physical card. You purchase and activate it online before you travel — or at the airport — and it loads onto your device without swapping cards. Several international providers offer Thailand eSIM plans; the major Thai carriers also sell eSIM directly. The advantage is convenience and the ability to keep your home number active on a different line; the trade-off is that plans and top-ups are managed through apps rather than a walk to the nearest 7-Eleven. Check your phone's compatibility in settings before assuming it works.

WiFi on the island — the no-SIM option

Almost every guesthouse, resort and hotel provides WiFi, and the quality ranges from a slow shared connection in a bungalow resort to the fibre-equivalent speeds at the coworking cafes in Sri Thanu and Thong Sala. If you are only using messaging apps and a little social media, hotel WiFi may be all you need and a local SIM an optional extra. For anyone working remotely — video calls, large uploads, consistent sessions — relying on hotel WiFi alone is a gamble; coworking spaces and cafes with dedicated fibre connections are the reliable alternative, and a data SIM gives you backup for sessions away from them.

Data usage tips for the island

Before you arrive, download offline maps of Koh Phangan — the island's winding roads and occasional dead-end tracks make offline navigation a genuine time-saver even when you have data. WhatsApp, FaceTime and other messaging apps are the most data-efficient way to call home; save video calls for WiFi. Streaming audio or video burns through tourist data packages quickly — if you're a heavy streamer, buy the largest package available or supplement with a WiFi top-up. Google Maps and Apple Maps both work reliably on the island for navigation in the main areas; for the more remote tracks, a downloaded offline version is the practical safety net.
