Iphone5s always sends text messages automatically, every few hours, asking for help. For example, I sent a message to a friend last night, and then every time

1. In the SMS settings, check whether there is a plan to send SMS automatically. First, check whether the content sent each time is the same. If they are the same, it means that automatic scheduled transmission is set.

2. If it is not set or the content sent is inconsistent, it depends on what it is. For example, the content sent is: I am downloading it quickly with Momo artifact. For example, I am using XXX software to add things quickly. Then delete the software on the phone.
