Call the other party, and the mobile phone prompts the other party to open the SMS service, so does the other party turn off or stop?

In fact, this is a call transfer, and you can set four different situations to transfer! 1 means no signal, 2 means no answer, 3 means incoming call, and 4 means all transfer! It depends on what kind of settings the owner makes. Most of them are turned off. If the host doesn't want to answer any phone calls, but wants to know who is calling himself, you can set an unconditional turn. Then he can leave his mobile phone on and receive a system message telling him who called him. The caller can only ask for help by SMS! I suggest you open the SMS to report, so you can send a message to know whether he is open or closed! This is the most accurate!
