HOW TO IDENTIFY AN ANONYMOUS TEXT MESSAGE?

Hi calimeromj, I read your message, and I wanted to say that there are very few ways to know who the real author of the messages is.
Moreover, these numbers are indeed numbers that you can find on the internet, which are either free or paid, but anonymous in one way or another; these numbers are designed not to provide information.
But for you to have filed a complaint for defamation and invasion of privacy is a good thing.
I'm sorry for not being able to help you more...
hoping it gets resolved quickly.
Take care.

Yeah, but if the anonymous texts are insulting or threatening, they'll react quickly in the face of a threat from the CNIL; if they can't find the culprit, it's them who are liable… And there's no need for the time, it's enough to look at the phone number, and I suppose it’s not necessarily in the site’s log since they must go through something phone-related at some point or another, and maybe there's a log for that which is less of a hassle...
