What is Unicom's voice warning?

When the number of voice minutes in the user's package is insufficient or used up, the system will send a short message to remind you accordingly. The specific reminders are as follows:

1. User voice resource shortage reminder: triggered in real time when the voice usage in the user package reaches the early warning threshold; Reminder elements: end time, used quantity and remaining quantity.

2. Voice resource exhaustion reminder: triggered in real time when the voice minutes in the user package are exhausted.
