Internet and Wi-Fi in Thailand
What to expect from mobile coverage, public Wi-Fi and data options in Thailand — and the simplest way to get online as a visitor.
Mobile coverage in Thailand
Fast, cheap mobile data almost everywhere, including most islands.
Local networks
Our Thailand eSIM connects to these local mobile networks, the same ones domestic SIM cards use:
- TrueMove H
- DTAC
Can you rely on public Wi-Fi?
Hotels, cafes and airports in Thailand usually offer Wi-Fi, but it rarely helps when you need a connection most: navigating between places, checking transport in real time, or calling a ride from the street. Public networks are also unencrypted more often than not. Treat Wi-Fi as a bonus, not a plan.
The easiest way to get online
A prepaid eSIM for Thailand installs on your phone before you leave home and connects to a local network automatically when you land — no store visits, no paperwork, no roaming fees. Plans start at $0.51.
