When calling the other party's mobile phone, is it possible that the other party intercepted it with faithfulness or some software?

I used Yi 'an, and Yi 'an is actually very powerful. But you said you heard the announcement voice, which was never sent by Xinyi 'an or any other software.

Because the interception software of Xinyi 'an mobile phone is a very common answer, after ringing again, it only says "the number you dialed is not in service area" and "the user is temporarily unable to connect", or there is no sound.

But "Call the assistant business, remind by free SMS ..." You are only talking about customized business.

Don't worry, if you want to know what the specific business is, you can call 10086 or 100 10 for consultation.
