We invite you. Telecom is a first-class broadband operator, and Great Wall is a second-class. First-tier operators shoulder more social responsibilities, with higher costs and unified and relatively fixed tariffs. Great Wall is a pure enterprise, with low cost and flexible tariffs, and can formulate tariff policies according to local conditions. In terms of network speed, the best has always been ITU, which can&;t be compared with others. In terms of service, pure enterprise service is better.
