Paramedics used the ''jaws of life'' to try to free Vorasak Rungswang, 29, from the vehicle but it took them one hour.
Khun Vorasak, alive when rescue workers began to cut him free, was dead by the time he could be removed.
The impact of the crash when his taxi ran off Thepkasattri Road at the Mak Prok curves left the vehicle bend around a power pole about 12.45pm.
Police believe Khun Vorasak, on the taxi rank at the JW Marriott Resort and Spa in Mai Khao, on Phuket's holiday west coast, was responding to a request to pick up passengers at Phuket International Airport.
His body was taken to Thalang Hospital, in central Phuket.
