Shanxi Changzhi, Telecom, Netcom and Tietong, which broadband network is the best?

North Netcom has done a comprehensive job with a wide coverage, but the service is poor and the price is more expensive. Telecom is now expanding its business and doing a lot of activities. The coverage is not very wide. You can call and ask if you are in the service area. As for the network speed, there is not much difference between the two. You can give up Tietong, the service is still poor, the network speed is very slow, and no one will pay attention to you after installation. Suggest Netcom, or Telecom. Personally, I think telecommunications is more affordable.
