Does Changchun Dorn Residential Island have telecom broadband?

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

You can call the service hotline 10000 of the telecom company in advance for consultation, but pay attention to the fact that telephone consultation with customers may not be as accurate as the local business hall.
