If you’re planning to stay connected during your visit to Thailand, buying a local SIM card is one of the first things you’ll want to do. But before you insert it into your phone, be aware of Thailand’s SIM card registration rules for tourists that will be enforced in 2025 — they apply to all users, including tourists.
Here’s everything you need to know in 2025.
🪪 Is SIM Card Registration Required in Thailand?
Yes. Since 2015, the Thai government requires all SIM cards — including prepaid tourist SIMs — to be registered to the user’s identity. This regulation helps authorities track phone use for security purposes.
🛬 Can I Buy a SIM Card at the Airport?
Absolutely. In fact, it’s often the easiest option.
📍 Available at:
Bangkok Suvarnabhumi (BKK)
Don Mueang (DMK)
Phuket (HKT)
Chiang Mai (CNX)
✅ Registration is Done on the Spot:
When you purchase a SIM card at a kiosk, they’ll take a photo of your passport and complete the registration process instantly.
