Are you there? I am friends with each other. Can he get my message?

Under normal circumstances, if there is no problem with the function of the mobile phone, if you can send it normally, it should be able to receive it normally. If I didn't reply to your message, there are probably several reasons. One is that I didn't see it because I was busy at work, or I forgot to reply to you because I was busy. The other is that I don't want to reply to you. Needless to say! Another is that you didn't receive it, such as blacklisting you and so on.
