SIMs, eSIMs & hotspot advice for Thailand
Buy a registered tourist SIM at airport kiosks or pre-purchase a verified eSIM; choose larger data bundles if you plan to tether a laptop.
Quick take: AIS, TrueMove H and dtac provide the best nationwide coverage; expect excellent city LTE/5G and weaker signals on small islands and remote highlands.

Why this matters
Official kiosks at BKK, DMK, HKT and CNX sell registered tourist SIMs and quick eSIM activation by QR code.
If you need laptop tethering, choose mid‑to‑large data bundles or rent a pocket Wi‑Fi for group use.
Check AIS/True/dtac coverage maps before island or highland travel; carry a backup SIM or offline maps.

Confirm your phone is unlocked and eSIM-capable before buying an eSIM.
