Why can't I see the number of the short message sent by others, and I can't find it on the mobile network.

Science and technology are progressing rapidly. Mobile technology is provided by other companies, and I haven't mastered the core technology yet. It's just a machine to build a station. All the short messages I received were sent from an ip address, with 6 or 7 messages a day. I am depressed, too. I called my cell phone and the other party said there was no way. There are so many cases like this that there is nowhere to complain.
