Thailand eSIM — Frequently Asked Questions
Does eSIM work in Thailand?
Yes — eSIM works across Thailand on major local networks. You'll have 4G/LTE coverage in Bangkok, Phuket, Chiang Mai, Koh Samui, Pattaya and most tourist areas. Coverage extends to major islands and resort regions.
How do I set up my eSIM when I arrive in Thailand?
After purchase, you'll receive a QR code by email. Scan it in your phone's Settings before your flight. Your eSIM activates automatically when your phone connects to a Thai network at Suvarnabhumi or Don Mueang airport — no queuing, no SIM swap required.
What network will my eSIM use in Thailand?
Your Thailand eSIM connects to AIS or DTAC — Thailand's leading mobile networks — giving you reliable 4G/LTE coverage across cities, beaches, and popular tourist areas throughout the country.
How much data do I need for a Thailand trip?
For a 2-week trip to Thailand with normal social media, maps, messaging and the occasional video call, 3–5GB is comfortable. If you're island hopping or streaming a lot, 10GB covers you well. Most hotels and cafes also have Wi-Fi, which helps conserve data.
Can I use eSIM on iPhone or Samsung in Thailand?
Yes. eSIM works on iPhone XS and later, Samsung Galaxy S20 and later, and Google Pixel 3 and later. Check your phone's settings under Mobile Data → Add Data Plan to confirm eSIM support before purchasing.
