10000 sent a text message saying that it was checked by big data. Is it true?

Fake. The investigation of big data should be based on the official telephone number, and other short messages should be ignored to prevent SMS fraud. SMS fraud refers to 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.
