My friend called him in recent days and kept saying that the other party had enabled SMS.

This is a mobile phone call assistant, which means that your mobile phone will send a message to tell you when there is no signal or it is turned off. If you want to cancel, just dial 10086 to cancel manually.

That means her cell phone is turned off or there is no signal for the time being.

, that is, the other party has a call reminder function.

The calling customer has opened the SMS calling service, and will receive the SMS reminder of your call after the phone is turned on ... Is this the state of power off or no signal? Will he receive a SMS reminder of your call or will he receive a SMS reminder of your call after "turning on"? Is there the word "after startup"?

Can you set this when you don't want to answer someone's phone, so that his phone can always be heard in this state? Actually, is the mobile phone turned on or has a signal? Just deliberately not answering?

I hope my answer is helpful to you. Good luck!

Work smoothly, study progress!

Timely adoption, thank you.
