Getting a Chiang Mai SIM card or eSIM are the first thing every smart traveller should sort before venturing into this beautiful city. Whether you are wandering through the ancient moat-circled Old City, trekking to Doi Inthanon - Thailand's highest peak - or hopping between the over 300 temples that make Chiang Mai the cultural heart of the North, staying connected isn't a luxury anymore. It is a practical necessity. In this guide you'll find everything I have learned from years of showing visitors around Chiang Mai: how much data you actually need, what network works in the mountain villages plus the old city lanes, what you'll pay for a SIM or eSIM, and the best spots to purchase one - so you can spend less time stressing about Wi-Fi and more time enjoying special moments with your family.
