AIS has the widest coverage nationwide, including islands like Koh Samui and Koh Phangan. DTAC and TrueMove H are strong in Bangkok and Chiang Mai. Expect weaker signal on remote islands (Koh Lipe, Koh Kood) and in mountainous northern regions near the Myanmar border.
Grab is essential for taxis across Bangkok, Chiang Mai, and Phuket — it requires constant data. Download offline maps for island-hopping trips. Google Translate's Thai camera translation helps with menus and signs. Budget 1-2 GB per day for active use.
Thailand introduced SIM registration requirements in 2023 — physical SIMs now need passport scanning. eSIMs bypass this process. Mobile banking apps like Wise work well for QR payments at 7-Eleven and street vendors.
