Why did you delay receiving the missed information?

When your mobile phone is in an abnormal state (power off, no power, no signal, etc.). ), it will be called to the call manager system, and the system will immediately generate a missed message and send it to the short message center. The time indicated in the missed message is the actual time when the missed message occurred. You can only receive the missed message when your mobile phone is in a normal state (the signal is turned on), and the SMS center will repeatedly send the failed message at regular intervals. In this way, there will be a delay between the time when you receive the missed message and the time when the missed message occurs, which is normal.
