Why did knowledgeable person send a text message saying that someone called me, but my cell phone didn't ring and there was no call record? It's telecommunications

Hello, it's my pleasure to serve you!

According to your description, because your mobile phone was turned off or the signal was temporarily bad, the number dialed by others was not connected, so there was no noise and no call record.

If you want to know more, please come to Zhihu platform of Anhui Telecom or online business hall of Anhui Telecom to ask questions, and there will be more professional customer service to answer your questions.

If you are satisfied with my answer, I hope it can be adopted. I wish you a happy life.
