Whispering that the attribution shown by anonymous SMS is the sender's attribution?

Quietly say that the attribution displayed by anonymous SMS is the sender's attribution, and the attribution can be found.

Anything sent by your mobile phone number can be found. Because the attribution of the middle four digits of the mobile phone number is assigned. It is invisible unless it is sent through some software.

And check the attribution through the mobile phone number. If you send a text message to others, others will know the software related to your mobile phone number and read out the attribution of your number.
