Pick by travel style

🧘 Digital nomadsThe 30-day big-data tier is cheapest per GB, and hotspot sharing matters beyond café Wi-Fi.

FAQ

eSIM vs airport SIM in Thailand — which wins?

Prices are close, but eSIM skips the queue and passport registration entirely; airport counters run 20+ minutes in high season.

How widespread is Thai 5G?

Mature in Bangkok, Chiang Mai and Phuket urban areas, 4G elsewhere — the best overall experience in Southeast Asia.

How much data for 7 days?

5GB covers moderate use; go unlimited-per-day if you'll stream or go live throughout.
