SIM card shops are widespread in China, and you can easily find them at major airports such as the Beijing Capital International Airport, Shanghai Pudong, Guangzhou Baiyun, Chengdu Shuangliu, and Shenzhen Bao’an.
You can also get Chinese SIM cards at kiosks and shops in most cities, or even from street vendors. However, we recommend buying your cards from official stores and websites only.
