The number you dialed is already activated. Is Tianyi hacked?

Communication assistant service is a value-added service provided by China Telecom to telecom mobile phone users. Its main function is to remind you of missed messages when the phone is turned off, the signal is not good, and the line is busy, as well as to inform you of new number changes, call forwarding settings, missed call inquiries, missed voice messages and many other functions.

Dial the other party's mobile phone number to remind you that the number you dialed has been opened. Tianyi voice communication assistant service sends messages, but generally the other party cannot receive them.

The other party uses the Tianyi card of Telecom, and the assistant service is Tianyi's business.

That is, when the owner is absent, the owner's mobile phone is turned off or in a state of no signal, when you dial the owner's phone, you will be prompted that the phone you dialed has started the Tianyi voice communication assistant service, and when the owner's mobile phone returns to normal, a message will be sent to inform the owner of your call. In this case, the owner can't receive the message you sent.
