How about installing Unicom optical fiber broadband in Yichang, Hubei? Have used friends to help me, thank you!

What you said about China Southern Telecom and China Northern Unicom are only advantageous operators differentiated by geographical location, and will not affect the use of basic broadband.

If you build a new residential area, I suggest that you install any company's products on any line, because the general residential area manager (property) will sign an exclusive access agreement with the communication company in order to maximize his own interests, so that the property can get a lot of benefits, but he needs to prevent other network operators from entering the line.

According to the situation of my new residential area, it is often that only one company's broadband products can be installed in a residential area. So, if you need to use broadband, you'd better not wait any longer, or you can contact the residential property and ask if your residential area will enter the line of the telecom company.
