Why did I receive a text message in Linping that I was in Jiaxing, Zhejiang?

A big reason is that your information is leaked.

Do you often click on some advertising links or abnormal links when watching online news or videos? When you accidentally order something you shouldn't, the other party will record your information in the background, because many softwares will read your address and telephone address book now, so it is easy for some marketers to even use it and send short messages frequently. Pay attention to protecting personal information, surf the Internet carefully, and don't click on the links in short messages.
