Do Mobile Networks Work During Island Tours?
Koh Lao Lading
Yes — on most popular routes, coverage is strong enough for calls, maps, and messaging apps. Travelers are often surprised to find they can even livestream from a boat while surrounded by limestone cliffs.
Still, occasional “dead zones” exist in very remote coves, but they’re rare and short-lived. For most tourists and digital nomads, this is more than enough to stay connected.

SIM Card vs. eSIM: Which One Should You Choose?
Phi Phi Island
