Good to know before you go to Thailand
Thailand covers the classic backpacker route well — Bangkok, Chiang Mai, and the main southern islands (Phuket, Koh Samui, Koh Phi Phi) all have strong, reliable signal, and it keeps getting faster in Bangkok. Coverage gets patchier the further you go into national parks or remote northern hill towns. Data use here tends to run high because of navigating songthaews and Grab, translating menus, and video-calling home across the time difference — 10GB+ is a safer floor for a two-week trip than the 3-5GB that works fine for a short European city break. If you are diving or on a remote island for a few days, download offline maps before you lose signal.
