1, netcom, the tariff is cheaper than telecom, because netcom and telecom compete, but there are few competition areas, so the cost is definitely cheap, but the network speed may not be guaranteed, because many places rent telecom equipment, who will rent good equipment to competitors, but not all places are bad, you can ask the owner of the same community how to use it, because there are also some communities where netcom makes its own equipment, which can be guaranteed.

2, telecommunications, operating in China for many years, from better equipment to the widest line, is basically in a monopoly position in southern provinces, so the cost is more expensive than Netcom, not without reason.

In a word, it depends on your actual situation. If you just browse the web, you can choose Netcom if the speed is not high. Don't waste the money you can save. It is not easy to make money. If you want to play online games, I suggest you install telecommunications, which is relatively stable. It's best to ask people around you how to use telecommunications and Netcom first, and then handle it according to your actual situation.

In addition, the group IDC has many products online, which are cheap and have a good reputation.
