How to set someone to call you and ask him to leave a message when your mobile phone is turned off, and prompt you to listen to the message when it is turned on?

You can confirm whether your mobile phone has this function of prompting voice messages.

In addition, Unicom's calling treasure service can also be understood as a service with the function of reminding missed calls. When the called party is turned off (or there is no signal) after the calling treasure service is started, it will receive a short message reminder after the phone is turned on, showing the missed phone number and dialing time during the shutdown period, so as not to miss important calls.

Tips:

1. Calling Bao service and Unicom secretary service are mutually exclusive and cannot be used at the same time.

2. You can send "1" to "10655811"or "0" to "106558165433".

3. If the call information service is a necessary service, please don't cancel it yourself during the use of the corresponding package.
