There are two ways to achieve wireless Internet access: wireless network card and wireless network card, the two are two different concepts, the wireless network card must be used with the wireless cat or wireless router, and finally it is basically necessary to use broadband to achieve Internet access, and some can also access the Internet through the operator's wireless hotspot; But the wireless network card is through the operator's mobile network to access the Internet, the tariff policy is also different, different from place to place, it is recommended to use China Telecom's 3G wireless network card business, because the current China Telecom's 3G network has covered all cities in counties and above across the country, which is far from being comparable to the other two, and the signal stability is also the best, as for the tariff, you can directly consult the local telecom customer service 10000

Network card refers to computer hardware, through the network card, you can connect to the network Internet card, refers to your account and password, only through the verification of the network card, you can log in to the network In layman's terms, the network card is your house, you can only live if you have a house.
