Internet access is still the most important! ! !
I am in the north, my dormitory is 5 12k telecom network, and my home is 4M Netcom. The biggest feeling is that things are transmitted between two networks, which is simply a torture. A famous saying of my classmate: The furthest distance in the world is not from China to the United States, but from Netcom to Telecom.
From good to bad, each has its own advantages, depending on your needs. If you are from the north, it is better to install Netcom, because the coverage in the north is relatively large, so surfing the Internet, downloading and playing games will be enough. If you go to the internet or game server in the south, it will be slower. On the contrary, the telecom coverage in the south will be wider. Personally, the network speed and service of Northern Telecom are very unstable, which is not as good as that of Netcom, because after all, Netcom has a large coverage, will develop faster, the more users, the higher attention, and the better and more stable service and maintenance. It is estimated that the same is true for China Southern Telecom.
Now, of course, two networks are popular all over the country, many websites, games, ftp servers and so on. It is more and more convenient to have two lines or multiple mirrors.
