Phuket eSIM: online from the airport to the beaches

Phuket pairs an airport bus to the town with a beach bus down the west coast. With the eSIM on, the ride south is on the map from the start.

The short answer

A Phuket eSIM is installed at home before you fly and switched on when you land, with data roaming on for the line. Phuket International (HKT) is the island's airport: the Smart Bus runs from the domestic terminal down the west-coast beaches to Rawai for a flat 100 baht, and the orange 8411 bus runs to Phuket Town.

Before you go (Phuket)

Install the eSIM at home on Wi-Fi and keep the line switched off until you land. Download offline maps and your tickets while you still have Wi-Fi, in case a temple or a boat trip has no signal. On arrival, switch the eSIM line on, choose it for mobile data and turn on data roaming for that line only.
