📶 Internet and SIM Cards in Chiang Mai

Don't buy simcard at the airport. If you visit AIS or Truemove at the mall and make the sim card there, it can be used for many months. They has much cheaper plans. I use about 80G LTE at 300bhat for month.

Get AIS SIM at 7-Eleven. 299 THB for 30 days unlimited 5G data. Coverage is excellent throughout the city. They have English-speaking staff at airport if you need help setting up.
