Why does the short message information report show that it was sent successfully, but the other party can't receive the short message?

The reasons why the SMS was sent successfully but not received by the other party are as follows:

1. The receiver's memory is full, so just delete the redundant SMS.

2. The receiver's signal is poor, so it is recommended to send it to a place with good signal.

3. The processing of short message center is affected by congestion, packet loss or interconnection obstacles.

4. SMS function is not enabled.
