After receiving the text message, the mobile phone was detected as illegal.

I think it's a liar. He actually sent me a reminder message from Unicom on my mobile phone. If you want to send it on the stage, it will definitely not be Unicom. Maybe there is something wrong with some software you installed. Pay attention to whether it will be sent to you every time you use it or run out. The software had better be downloaded from official website! !
