Which taxi is best to call to the airport? It seems not all taxis are allowed on the territory.

You’re right, only Grab taxi service is allowed on the airport territory. You can order a car through the application. You don’t need a foreign card for registration, and you can use your country’s phone number, then pay for the trip in cash with baht (or link a bank card if you have one).

Other taxis, like InDrive and Bolt, are not allowed on the airport territory, so they stop nearby – you’ll have to walk about 300 meters. We wrote in detail about transport in Phuket.
