If you’re planning to visit Thailand in 2025, one of the first things you’ll need is a reliable internet connection. While free Wi-Fi is available in many hotels and cafes, it’s not always secure or fast enough for navigation, booking services, or sharing your adventures.
That’s why most travelers choose a prepaid SIM card or an eSIM for instant internet access anywhere in Thailand.
In this guide, we’ll compare the top 5 prepaid SIM cards for tourists in Thailand so you can choose the best one for your needs.
