There are two types of wireless Internet access: wireless network card and wireless network card.

Wireless Internet cards are GPRS Internet cards, 3G Internet cards and other things.

A wireless network card is used to access an access point such as a wireless router or wifi.

A Wi-Fi card is definitely going to cost money, exclude.

Wi-Fi is available at airports, cafes, and other places for free. There is also a kind of stealing other people's access point Internet access card, cracking other people's wireless password secretly. However, this kind of equipment has a large radiation explosion, and it is typical to be greedy for small and cheap to lose big.

The people who sell these cards don't need it themselves.

Internet access is all about passwords.

What terminal to use.

It's not right to steal someone else's Wi-Fi.

And that kind of thing radiates a lot.
