The first-tier operators are Telecom and China Unicom, and the second-tier operators rent their lines, such as Great Wall Broadband. The first-tier operators are relatively stable and really enjoy broadband, while the second-tier operators are generally * * *, so the second-tier operators will cause slow network speed during peak hours.

Operators refer to network service providers, such as Nokia and Samsung. The manufacturers of communication equipment are called manufacturers, and China Unicom, China Telecom, China Mobile and China Radio and Television are called operators. Because the state is very strict in telecommunications management, only companies with operating licenses issued by the Ministry of Industry and Information Technology can set up networks; From the perspective of communication industry, equipment manufacturers and operators are interdependent, but operators generally have more advantages, just as China Mobile stipulates that some mobile phones produced by Nokia and other mobile phone manufacturers should be branded with GSM.
