Many public places such as stations and hotels are covered with free WiFi, which is unsafe. Some WiFi users need to enter their mobile phone number if they want to connect, but there will be greater risks in this process. Some businesses may write down customers' mobile phone numbers and earn a lot of profits by selling personal privacy, and some businesses will also promote them.

In this case, it is recommended that you do not connect to WiFi, and you can use the data on your mobile phone directly. At the same time, some hackers may drill some loopholes, and sometimes they will monitor or analyze the network. Because the main purpose must be to get everyone's payment account or password. If the link is delayed, it will fall into the trap set by others, thus causing a lot of money losses. And this kind of WiFi has a great feature, that is, the speed is very slow. Although you can open a link, you need to wait a long time if you want to get the information you want.

If you want to avoid this kind of thing from happening to yourself, you can be vigilant. At the same time, try not to enter passwords or send some secret files or emails, otherwise you will be criticized by your boss. At the same time, some merchants will paste the password directly on the wall. Be sure to confirm it again and again. If the WiFi name is wrong, it won't work. Some people's mobile phones will set the WiFi to the automatic connection mode, and try to turn it off before going out.

It's not easy for anyone to make money. You must protect the money in your pocket. There may be Trojan viruses in WiFi, which are set by scammers in advance. Open the mobile phone software without knowing it, so everyone must clean up and detect the virus in time, and try not to install some unknown software. You can give relevant information to the elderly at home, because many elderly people don't understand the complex network environment.
