Why do you often receive spam messages?

Our mobile phones usually receive spam messages. There are two kinds of spam messages, namely advertising messages and fraudulent messages, and general advertising messages, such as business activities. The bills of hotels, supermarkets, restaurants, shopping malls, Taobao sellers, as well as short messages from banks, insurance, mobile Unicom and Internet broadband, have everything. Can't even stop. According to the statistics of the Ministry of Industry and Information Technology, tens of millions of short messages are edited and sent out every day.

First, this part of our figures came from our carelessness and leaked out. For example, we went out shopping, went shopping, participated in activities, left our phone number as a gift, and inadvertently left our number, so merchants sent text messages to promote advertisements.

Second, some businesses use their own numbers to exchange data with other businesses, and we don't know it ourselves. How can we receive some unknown text messages?

Third, some organizations, companies and individuals only sell telephone numbers, and they collect all kinds of numbers through various channels. For example, the recruitment, job search, express delivery and sign-in registration we posted, or the space and number of friends we posted were inadvertently recorded by others.

Fourth, every region, regardless of Unicom's mobile phone number, is regular. Some people use computer algorithms to synthesize numbers. For example, 1350577 ~ 1, 1350577-2, 1557599 ~ 1 may be troublesome, but it is relatively safe and legal.

Merchants get numbers in these ways, and then use software to send them in groups. In the past, Fetion could be sent in groups, but now Taobao can replace group software. You can send it after you enter it.

I was cheated once, and the phone bill of 100 yuan was gone in ten minutes. But I will never order it again.

In short, a word of warning, if you don't take advantage of small things, you won't suffer.
