How does Shantou Mobile send a message to join the cornet?

You need the code of the cornet group you want to join, then send it to 10086 at will, and then cancel or handle it according to the cornet group selected in the reply, and follow the prompts step by step. However, I suggest you dial 10086, choose manual, tell him the full name of the cornet group you want to add, and he will let you confirm your local password, so it's ok, simple! Then you can use cornet next month!
