Doris, there are three telecom operators. You need to choose one according to your phone configuration. If it supports WCDMA/GSM, you should buy one from China Unicom. In some airports, there are branches of China Unicom. You can go there to buy a SIM card. If you plan to access internet, then you need to subscribe data packages. Do not forget to tell the staff about this.
