1. You can't install broadband without a telephone line. You must have a phone. The cheapest one is 20 yuan.
2. I have a 2-meter monthly subscription, and I want to deposit 300 phone bills (the internet access fee will be deducted from your phone bill), monthly 128, 1M 108, plus the initial installation fee 188. And I have to buy a cat, only a few tens of dollars, to go to the computer city TP -LINK one.
I can't do it without a local ID card. Although I'm not from Changsha, I got an ID card in Changsha and wrote the address of our school, so I got away with it. You'd better discuss with the landlord and see if he will help me.
One more thing, Changsha's policy is that the monthly subscription must be used for one year. Even so, it's like using PHS for a year. If you don't want to use it, telecommunications won't come to you so freely.
