Want to send messages or call a person's mobile phone number continuously. Is there any way?

This may require a professional software and the support of your mobile phone. Just like Samsung's, it can be set to turn on the phone regularly and make phone calls regularly.

But maybe I don't know much! It seems that this function is not used on the mobile phone for the time being. Try fetion. It might be useful. Write it out, save it, and send it by computer!
