How to send a short message to open a call reminder on Unicom mobile phone? It means that there is no signal and there is a SMS reminder when the phone is turned off.

Unicom's calling treasure service can 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.

4. The operation of different cities is different. Please refer to the cancellation method of local Unicom.
