AIS 4G and DTAC 4G cover the Old City, Nimman, Doi Suthep and the central Chiang Mai corridor with reliable data for songthaew rides, Grab and Bolt rides, PromptPay payments at the Sunday Walking Street and cooking class reservations. Signal holds along the entire Nimmanhaemin Road corridor and inside the modern MAYA Lifestyle Shopping Center, drops inside the older brick halls of the temples in the walled Old City where the ancient brick walls and the gilded pagodas block reception, and weakens on the upper mountain trails of Doi Suthep where the forested elevation and the distance to the nearest tower reduce the line of sight.

Yes. Use your physical SIM for calls/SMS and the eSIM for mobile data. Disable roaming on your physical SIM.

Yes. eSIM offers instant activation without visiting a store. Coverage matches physical SIMs in covered areas.
Yes. 4G works at the base of Doi Suthep and inside the Wat Phra That temple complex for navigation and photos, but expect the signal to weaken as you climb the upper mountain trails because the forested elevation and the distance to the nearest tower reduce coverage. We recommend downloading offline maps before taking the songthaew up the mountain because the upper temple stairs have thin coverage. Your eSIM is useful for booking ethical elephant sanctuary visits on Klook, PromptPay payments at the Sunday Walking Street, and songthaew negotiations with Google Maps translations. Note that the local songthaew rides are cash-based; your eSIM keeps the data running while you use the maps to confirm destinations.
