Telecom's 3G seems to be a wireless Internet cafe, so don't expect anything. Even if the signal can cover the network, the wireless network is extremely unstable and will be affected by weather, terrain and other factors. In addition, it is also related to the signal receiving and transmission ability of your machine's wireless network card. This is the same as TV. Just watch TV with antenna and cable TV, so I still suggest you use cable network with cable network. Moreover, this 3G project of Telecom has just started to build network equipment, which is still not perfect.

We always recommend that you use a wired network.
