How to check the anonymous text messages sent by SMS birds?

1. Read the data carefully to see if there are obvious contradictions or irrationalities and judge its authenticity.

2. Search for relevant information through search engines or social media to see if other people have received similar short messages and judge whether it is done by the same person.

3. The above methods can't determine the identity. Try to reply to anonymous text messages and pay attention to protecting personal information. Don't disclose your ID number, mobile phone number and other sensitive information to each other.
