Daily Life Services—SIM Card

(I) Foreigners can bring their passports or Foreign Permanent Resident ID Cards to the service branches of telecom operators such as China Telecom, China Mobile, and China Unicom, to purchase a SIM card and activate mobile communication services in China.
(II) The mobile communication service plans usually include call time and data. Different operators will provide different service plans according to customers' needs, and users can choose the appropriate one.
Note: The plans often offer a limited amount of data. They can disable internet access when not using internet services if the data offered is little. Or, they are suggested to consult the telecom operator for an appropriate data plan if they need to use a large amount of data.
