Can I buy a phone card at Taiwan Kaohsiung Airport? Thanks

Yes, you can find it at the gate when you leave the country, until 10:00 at the latest

Which airport in Taiwan has an operator counter that sells phone cards? Use Chunghwa Telecom for going up the mountain and down the sea, Taiwan's largest telecom operator, with a good signal.

There are sales points for phone cards and traffic cards at the airport. After you leave the customs, ask the information desk and they will tell you the direction.

Yes, the three major telecom operators in the pick-up hall all have counters, and they all have an all-you-can-eat data plan. The signals of the three operators are similar. Pay attention to whether the mobile phone system is compatible. Taiwan’s 4G frequency bands are FDD band 3, 7, 8, and 28
