Which family in Yantai uses broadband?

Hello, homeowner ... Now Yantai's home broadband is mainly telecom, Netcom, Tietong, Yintong, radio and television ... The fastest one should be Netcom. The download restrictions are similar. It's just that a broadband account is not allowed to connect multiple machines ... I'm using Yintong now ... because I'm an old user, the price is very cheap, but the network speed is not very fast. In addition, sometimes it will be disconnected. I will come back to be Netcom ... but the disadvantage of Netcom is that.
