Getting a Chiang Mai SIM card or eSIM are what every clever visitor should handle first before venturing into this incredible city. If you are wandering through the ancient moat-surrounded Old City, trekking to 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 is no longer a luxury. It is a practical necessity. In this guide I share everything I have learned from many years of showing visitors around Chiang Mai: how much data you actually need, which carrier covers the mountain villages as well as the old city lanes, the price of a SIM or eSIM, and the safest places to buy one - all so you can spend less time stressing about Wi-Fi and more time creating lasting memories with your family.
