Why do you receive text messages from friends in the same city?

Your mobile phone number information has been betrayed.

Some websites sell customer information. I think you have registered on some unknown websites and filled in your email address. If the website has a friendly link to the website, then the customer information of this website will be stolen by other websites. A website will send you information so that you can click on it and learn about it.

It's probably SMS fraud. Don't trust him. The act of using SMS to defraud money or finance. With the improvement of people's cognitive level, the language and content in short messages are changing with each passing day. Even the words "Notary Office Notice" appeared. And these are just the tip of the iceberg of fraudulent text messages.

Fraud cost:

The technical content of SMS fraud is not high. Through a group sender, several short message cards, a mobile phone number segment and a computer (sometimes without a computer), a large number of fraudulent short messages can be sent in groups.

Among these devices, the most critical part is the short message card, which is no different from the mobile phone SIM card sold in the market. When texting, the card number of the card will be displayed on the mobile phone, but it can only be used for texting, not talking. All short messages must be transmitted through the operator's platform and pay a certain fee.
