Why can't I get a text message from a mobile phone? ! ! ! !

My mobile phone has appeared before. When I went back to my hometown, the message sent by my mobile phone could not be received. And it's a little specific. The information from the service desk will be received. I called the service desk of China Telecom to have it tested, and I refreshed and restarted the information platform of my telecom mobile phone number. No problem in the back. You can try it like this.
