Good to Know
- Koh Phangan's internet is suitable for location-independent work like writing and design, but not ideal for video-intensive work or large file transfers.
- For stays longer than 15 days, buy a cheap local prepaid SIM at 7-Eleven and top up with monthly packages through the carrier app—far better value than tourist packs.
- AIS provides the best coverage beyond town center and is recommended if you plan to explore the island; TrueMove H offers the fastest speeds in town.
- Public WiFi networks on the island are often unsecured; always use a VPN when accessing public networks to protect your data.
