What should I do if I want to pay for a ticket abroad by credit card but need to use a Taiwan mobile phone number to receive a credit card verification code SMS?

Step 1: Confirm that the "Voice" roaming function has been enabled on your Taiwan Telecom number
It is recommended that you confirm whether the international calling and text messaging functions of your Taiwan SIM card are enabled before going abroad. The default settings of Taiwan's telecom operators may be disabled.
