Portable WIFI that can be charged is reliable
The principle of portable wifi is equivalent to the Internet module inside the mobile phone, the wireless network card inside the computer, as long as the use of the place has mobile, Unicom, telecommunications signals, you can access the Internet, the stability of the portable wifi network directly depends on the local operator network conditions, not the portable wifi device itself can be decided. For example, our own mobile phone sometimes has a good signal, and sometimes the signal is different.

2. Whether the portable wifi Internet access is safe, will not steal confidence

This worry is redundant, portable wifi a mobile phone, the principle of the router is the same, usually we do not have a network can also accept the connection to the outside of the public network, portable wifi is more secure than this public network.
Unreliable, because the signal is unstable, the portable WIFI signal that can be charged is not stable enough, and the signal strength can only reach one grid, so it is not reliable, at the same time, the rechargeable battery can not provide continuous use of the wireless network for a long time, and the use of different wireless networks should be selected according to their actual situation in daily life, and the use of small and cheap can not bring huge losses to themselves
Unreliable, this WIFI is mostly to steal your phone inside the privacy rights, so it is best not to use
