When I call people in Taiwan Province Province, should I add something before the phone number? What about texting?

Add 00886 to the front, otherwise I recommend you to use the short message card of Taiwan Province Province, which is only 0.38 yuan at most. You don't need to add 00886 before entering the other party's number. When sending, the system automatically converts the information into traditional and sends it out, realizing automatic conversion of complex and simple, supporting reply, and receiving reply is free, and the other party only needs to pay the SMS fee of the operator to which his mobile phone belongs. In Taobao or Paipai, you can find "purchasing SMS card" or "Taiwan Province SMS" or directly find "Taiwan Province Bank SMS card".
