I used to do great wall broadband, but I didn't do it well! Telecom is good, but it's drag. This is the advantage of telecommunications! China Telecom is the best! Also helpless! You can find the telecommunications department and let them check and repair! Or go to their business hall. If you call, it is estimated that you will not come for ten and a half months! Otherwise, let's see if there is Unicom. Although it is unstable, it is better than you now! China industry is so rubbish!
