Thailand Travel Tips
Must-see hotspots
Grand Palace and Wat Pho in Bangkok, Phi Phi and Similan Islands, Phuket, Krabi & Railay, Chiang Mai and Doi Suthep, Ayutthaya historical park, floating markets, and the northern hill tribes.
Data planning
Plan for 3-5 GB/week for typical travel use (maps, messaging, photos). If you stream video or work remotely, consider 10+ GB. Top-ups are simple via the Simology app.
Insider tips
- — Public Wi‑Fi can be inconsistent or unsecured — use your eSIM for safer, more reliable access.
- — Use mobile data to navigate BTS/MRT in Bangkok, check regional train schedules, and book ferries or long-distance buses.
- — Thailand’s cool season (Nov–Feb) is ideal for travel. Hot season (Mar–May) can be intense; monsoon season (Jun–Oct) brings heavy rains and occasional transport delays.
