Can Shandong Telecom's cool card open the extremely fast service?

You can't. Telecom Cool Card is a phone bill package, and there are traffic restrictions when using it. When the user reaches the set traffic threshold, the network speed will be forced to reduce, and there is no extremely fast service, but you can choose to buy a high-speed traffic package to meet the demand and improve the network speed experience. Shandong Branch of China Telecom Co., Ltd. (hereinafter referred to as Shandong Telecom) is a directly affiliated branch of China Telecom Group Company, which was incorporated in June 2002.
