For Phuket, use Saily’s Thailand eSIM: $2.99 for 1 GB and $7.99 for 5 GB, and the same plan keeps working on Phi Phi, Krabi and back in Bangkok.
The catch: plans are data only, so you get no local phone number for calls or texts.
Phuket trips are full of boat times, Grab rides from Patong and beach-club bookings. A Thailand eSIM set up before you fly is ready at Phuket airport.
