The Thailand plans in our database use AIS, True, DTAC. Where a provider hasn't published it, the table shows "Network not published". AIS and TrueMove cover cities and islands well. You may briefly lose signal on boats between islands.
For maps, messaging and light browsing, about 0.3–0.5GB a day, so 3–5GB is enough for 7 days. If you often watch videos or share a hotspot, consider unlimited data. To save money, choose Airalo 50GB · 30 days, the best value per GB (US$0.55 / GB).
Most providers don't list hotspot limits in their details, so please read the plan details before you buy. A travel eSIM is data only and works alongside your own SIM, so WhatsApp keeps working. Calls and SMS to your usual number still go through your own carrier (roaming charges may apply).
Thai carriers such as AIS and True sell tourist SIM cards. Under the rules of Thailand's telecom regulator (NBTC), they must be registered with your passport before use. A travel eSIM can be bought and installed before you leave, so you just turn on data when you land. Both work, so compare plans by trip length and data use.
