When I call the other party, the number you dialed is on the phone after the beep. Can she receive the message I sent?

SMS is ok. SMS is not restricted by hacking. It just blacked you out, but texting is ok. But if there is interception software in her mobile phone, she can't see it because it is all in the interception information. If she wants to read it, she can only read it in the interception message, but most people don't set it there. She can read it, but try to make it clear at once, and don't send it in three sentences, otherwise.
