Why does the mobile phone text message repeat more than ten times before it stops?

This is generally not a cell phone problem. If the other party keeps receiving the same message, it belongs to the problem of the SMS platform. It always recognizes that the received mobile phone has not been received, so it has been sending text messages. You can ask the recipient's mobile phone to take out the card and put it in another mobile phone, and then put it back after receiving the receipt. It will usually be fine.

Then you can call the mobile phone home 10086. They can help you solve this problem. (I used to work at 10086)
