Data tips for Thailand
- Ride-hailing apps like Grab and Bolt are widely used in cities and need data to book rides.
- Cafes and hotels in tourist areas usually have Wi-Fi, but coverage on boats and remote islands can be patchy.
- Beach days mean a lot of photos and videos. Save the uploads for your hotel Wi-Fi.

FAQ
How much data do I need per day in Thailand?
Most travelers use around 1.2GB per day with maps, messaging, social media and some music. Light users can get by on a few hundred MB, while heavy video streaming can push past 3GB a day.
Does Google Maps use a lot of data?
Hardly any. Navigation uses roughly 5 to 10MB an hour, and offline maps use none at all.
Should I get an unlimited eSIM?
Only if your estimate is above ~3GB per day or you rely on hotspot. Many "unlimited" plans slow down after a daily cap, so check the fair-use policy.
How can I use less data abroad?
Download maps, playlists and shows on Wi-Fi before heading out, turn off auto-play and background app refresh, and upload photos at the hotel.
