Start with how much data you need and how long you are staying. For short city trips a small 1–5 GB plan is usually enough; for longer stays or hotspot use, look at larger or unlimited plans. Check that the plan covers Thailand as a local or regional option, compare the price per GB rather than the headline price, and confirm your phone supports eSIM before you buy.
