Can the other party still send the intercepted text message?

Yes.

According to the Zhongguancun Online query, after receiving the text message, it is filtered and stored in the interception library. You can still read it if you want, so the other party who intercepted the text message can still send it, but it is stored in the interception library.

SMS is text or digital information sent or received directly by users through mobile phones or other telecommunications terminals.
