FAQs
Which network is best for the southern islands?
AIS generally holds signal best on Phuket, Samui and the smaller gulf islands; Dtac and True are fine in Bangkok, Chiang Mai and Pattaya. Beaches on the far side of islands are patchy on every network.
When should I activate a Thailand eSIM?
Most seller QR codes start the validity clock on first connection in Thailand, but a few start at purchase/installation — check before you scan. When unsure, install the eSIM at home but only enable data roaming after landing.
