5–10 GB covers many 10–14 day holidays with normal social use.

Airport vs eSIM
Airport SIMs are easy to find in Thailand. eSIMs remain nicer when you land late or connect onward the same day.
FAQ
Can I hotspots my laptop?
Often yes on fixed-data plans, but confirm the plan page. Unlimited products sometimes limit tethering.
Final recommendation
Price a 7–15 day fixed pack across Nomad, Saily, and Airalo first. Move to Holafly only if you know you are a heavy data user.
