You can only go to the Unicom business hall next to you for consultation, and their reply is the most authoritative, because if you cover fiber-optic broadband, the engineering department will input the information into the system, and the sales staff can accept it, otherwise there is no information in the acceptance system, and even if you want to install it for customers, you can't charge.

You can call Unicom's service hotline 100 10 in advance for consultation, but it should be noted that telephone consultation with customers may not be as accurate as local business halls.
