Notify each other by SMS.

1, when you call your boyfriend, your mobile phone prompts you to call, and the comic service has been opened. Notify each other by SMS. Of course, in this case, he fainted, and he just didn't want to answer your phone. But I was afraid of making you angry, so I arranged it.

2. There may be no signal or outside the service area. Blackening prompt tone drops off. By the way, your relationship is very delicate.

3. In this case, it is possible that there is no signal on the other party's mobile phone, and then there will be a short message prompt in the process of dialing the past. Including his cell phone, if you don't want to answer other people's calls, you can't call in. At this time, you will remind him by SMS.

Don't think too much, this is one of the services provided by operators. When you can't get through to the other party, Mobile will send a text message to tell the other party who called him. There may be many reasons why I can't get through, such as no signal, power off, and inaudible, so you didn't receive it. In short, if you can't get it, there will be a text message.

5. It may be that the signal of the other party's mobile phone is not good, or this prompt appears when the mobile phone is turned off without power. Please call again another time.
