Getting a Chiang Mai SIM card or eSIM are what every clever visitor should handle first before discovering this beautiful city. Whether you're strolling around the ancient moat-surrounded Old City, hiking up Doi Inthanon - the highest mountain in Thailand - or moving between the over 300 temples that make Chiang Mai northern Thailand's cultural capital, staying connected has stopped being a luxury. It is a real requirement. In this guide I share everything I have learned from years of showing visitors around Chiang Mai: how much data you actually need, which carrier covers the mountain villages plus the old city lanes, what you'll pay for a SIM or eSIM, and the most reliable vendors - all so you can spend less time fretting over Wi-Fi and more time creating lasting memories with your family.
